Finding a meal replacement shake that actually supports weight management may sound simple until you're standing in the supplement aisle surrounded by dozens of options, each claiming to be the solution. 

Some options are packed with protein but taste like chalk, others are sweet but loaded with sugar. And many promise clinical results without any clinical backing.

Meal replacement shakes can support weight management for some people when used thoughtfully, but quality varies widely. The best meal replacement shakes provide 20-30 g protein, under 5 g sugar, at least 5 g fiber, and complete micronutrients. 

In this guide, we’ll evaluate nine top meal replacement shakes based on nutritional composition, taste, clinical use, and real-world practicality to help you make an informed choice.

Let’s get right in.

Medical Disclaimer: This article provides educational information about meal replacement shakes and is not intended as medical advice, diagnosis, or treatment. Individual nutritional needs differ based on health status, medications, and metabolic factors. 

Always consult qualified healthcare professionals before starting any meal replacement program, especially if you have chronic health conditions, take medications, are pregnant or breastfeeding, or have a history of eating disorders. Results from meal replacement use differ significantly by individual.

What are meal replacement shakes?

Meal replacement shakes are beverages designed to substitute for a complete meal while providing balanced macronutrients (protein, carbohydrates, fats) and micronutrients (vitamins and minerals). 

Unlike protein shakes, which primarily deliver protein for muscle recovery, or smoothies, which blend whole foods, meal replacements are formulated to meet broader nutritional needs for some people.

These shakes serve several purposes:

• Weight management: Controlled calorie portions help create a calorie deficit for weight reduction
• Convenience: Ready-to-drink or quick-mix options save time on busy days
• Clinical programs: Many obesity medicine practices incorporate clinical-grade meal replacement formulated for use in medically supervised programs into supervised weight management plans

The key nutritional components of these shakes include:

• 15-30 grams of protein per serving to promote satiety and preserve lean muscle
• 3-6 grams of fiber to support digestive health and fullness
• 200-400 calories per serving to replace a meal without excessive energy intake
• Essential vitamins and minerals (often 20-30% of daily values)
• Healthy fats in moderate amounts for nutrient absorption

It’s important to know the difference between a quality meal replacement and a protein supplement. A true meal replacement addresses hunger and nutritional needs for several hours, while a protein shake alone won't keep you satisfied until your next meal.

9 best meal replacement shakes for weight loss in 2025

Disclaimer: Meal replacement shakes don’t directly cause weight loss. Instead, they support calorie-control during weight loss. There is also no ‘best’ choice for everyone. Results vary based on individual factors.

Note: The values in this table are obtained from the USDA. These rankings reflect general quality criteria. Individual needs vary based on health status, medications, dietary preferences, and goals. Consult a specialist before choosing.

1. Robard shakes

What it is: Medical-grade meal replacement designed for use within physician-supervised weight management programs, where specialists monitor nutrition, adjust recommendations, and ensure safe calorie restriction.

Who it's for: Patients working with obesity medicine specialists who want balanced macronutrients and 20-30% of daily micronutrient needs in structured programs.

Unlike retail shakes marketed directly to consumers, Robard shakes are formulated specifically for medical weight management programs with balanced macronutrients and complete micronutrient profiles.

Many patients have incorporated these into knownwell's weight management programs, with many finding them helpful for structured nutrition during calorie restriction when used under clinical supervision.

Key features

• Complete medical-grade nutrition: Each serving provides 20-30% of daily vitamin and mineral requirements alongside balanced protein, fiber, and essential fats. This prevents micronutrient deficiencies that can occur with calorie restriction
• Clinically tested formulations: Robard shakes undergo testing in medical weight management settings. They're designed for extended use under professional supervision, not just short-term dieting

• Used by obesity medicine care teams nationwide, providing clinical credibility
• Can be customized with additions (berries, nut butters) under dietitian guidance

Cons

• Not as sweet or dessert-like as retail options
• Higher cost per serving than mass-market retail shakes

Pricing

Available through knownwell's clinic shop as part of medically supervised weight management programs. Most patients purchase monthly supplies as part of structured care programs.

Bottom line

For patients in medically supervised programs, Robard is a common choice because its clinical-grade formulation ensures nutritional adequacy during calorie restriction. However, choices depend on individual preferences. 

2. Orgain organic meal

What it is: USDA organic, plant-based meal replacement with a complete amino acid profile

Who it's for: Vegan eaters or those avoiding dairy who want clean-label, allergen-friendly nutrition

Orgain stands out in the plant-based category for actually delivering complete protein without the chalky texture that many vegan shakes have. The combination of pea, brown rice, and chia proteins provides all essential amino acids.

Key features

• Organic plant protein blend: Pea protein, brown rice protein, and chia, delivers 16-20 g complete protein without dairy. This combination provides all essential amino acids in proper ratios.
• High fiber content: 8 g fiber per serving promotes satiety better than most competitors. The fiber comes from organic sources, including acacia gum and flaxseed.
• Clean ingredient list: USDA organic certification, non-GMO, gluten-free, soy-free, and kosher. Contains no artificial preservatives, sweeteners, or colors.

Pros

• Smooth texture without grittiness, which is rare for plant-based shakes
• High fiber (8 g) keeps you satisfied longer than lower-fiber options
• Organic certification appeals to clean-eating preferences
• Multiple flavor options with stevia sweetening (not artificial)

Cons

• Plant protein digests differently than whey, so some people find it less satiating
• Slightly earthy aftertaste that some consumers notice (though milder than many plant proteins)
• Higher price point than conventional protein shakes

Pricing

Costs depend on the retailer. Orgain organic shakes are widely available at grocery stores, Target, and Amazon.

Bottom line

Orgain is the go-to recommendation for plant-based eaters who don't want to compromise on protein quality or texture. The high fiber content supports satiety, and the organic ingredients align with clean-eating priorities. It won't taste identical to whey-based shakes, but it's one of the best-tasting plant options you can try.

3. Ka'Chava

What it is: Superfood-dense meal replacement with adaptogens, probiotics, and greens alongside protein

Who it's for: Health-conscious consumers who prioritize maximum micronutrient density and don't mind robust flavors

Ka'Chava contains superfoods, adaptogens, probiotics, digestive enzymes, and complete protein. The result of this combination is an exceptionally nutrient-dense shake, but with an earthy, complex flavor profile.

Key features

• Superfood ingredients: Maca, spirulina, acai, goji berries, camu camu, and dozens of other nutrient-dense ingredients provide vitamins, minerals, and phytonutrients 
• Digestive support: Probiotics, prebiotics, and digestive enzymes support gut health. This is important for people who struggle with digestive issues during dietary changes
• Complete plant protein: 25 g protein from pea, brown rice, and other plant sources provides all essential amino acids plus 9 g fiber

Pros

• Exceptional micronutrient density with superfood ingredients
• Probiotic and enzyme blend supports digestive health
• High protein (25 g) and fiber (9 g) promote satiety
• Made with organic, whole-food ingredients rather than isolates

Cons

• Complex, earthy flavor that some might find too intense
• Expensive compared to basic meal replacements ($79+ per bag)
• Dense texture that some find heavy or filling too quickly

Pricing

Available through Ka'Chava's website with subscription discounts, so pricing may vary.

Bottom line

Ka'Chava appeals to people who see food as medicine and want maximum nutrient density in every meal. The superfood ingredients provide good nutritional value beyond basic meal replacements. However, the flavor and higher price make this better suited for enthusiasts rather than those just seeking convenient calorie control.

4. Huel black edition

What it is: High-protein, low-carb meal replacement with 40 g protein per serving

Who it's for: Active individuals, athletes, or those following higher-protein eating patterns who need substantial protein in one meal

Huel Black provides protein (40 g per serving) with relatively low carbohydrates, making it suitable for people prioritizing protein intake for satiety, muscle preservation, or athletic performance.

Key features

• Maximum protein content: 40 g protein per serving. This comes froma  pea and rice protein blend providing complete amino acids.
• Low carbohydrate: Only 17-23 g net carbs per serving makes this work for lower-carb eating patterns. The neutral flavor base allows customization with fruits or flavors.
• Provides balanced macronutrients and 20-30% of daily micronutrient needs: Despite a high protein focus, it still provides vitamins, minerals, and fiber for complete meal replacement functionality.

Pros

• Highest protein content reviewed here (35 g), excellent for preserving muscle during weight management.
• Neutral base flavor allows customization with fruits, nut butters, or flavor drops.
• Lower carbohydrate content fits higher-protein eating patterns.
• Plant-based protein suitable for vegans.

Cons

• Higher calorie content (400 per serving) requires portion awareness for weight management.
• Some people find 35 g of protein in liquid form too filling or causes digestive discomfort.
• Powder-only format requires mixing (no ready-to-drink option).

Pricing

Available through Huel's website at variable prices.

Bottom line

Huel Black works best for people who need substantial protein, such as athletes, highly active individuals, or those following nutrition plans emphasizing protein for satiety and muscle preservation. The 400-calorie serving size and 35 g protein make this more meal-like than lighter options. However, if you don't need this much protein, you're paying for nutrients you won't use.

5. Garden of Life Raw Organic Meal

What it is: Raw, sprouted meal replacement using minimally processed whole-food ingredients

Who it's for: Raw food advocates or those seeking minimally processed, plant-based nutrition with very low calories

Garden of Life takes a raw-food approach to meal replacement using sprouted proteins and unprocessed ingredients to maintain enzyme activity and nutrient bioavailability.

Key features

• Low-calorie count won't satisfy most people as a complete meal replacement.
• Earthy, plant-forward taste not everyone enjoys.
• Lower protein (20 g) than other options despite the same serving size.

Pricing

Prices depend on the retailer. Garden of Life Raw Meal is available at health food stores and online.

Bottom line

Garden of Life serves a specific audience, raw food enthusiasts who prioritize minimal processing and enzyme activity. The grainy texture and earthy flavor require adjustment for most people.

6. SlimFast advanced nutrition

What it is: Highly palatable meal replacement that focuses on taste as well as an improved nutrition profile

Who it's for: Those prioritizing taste and convenience who are comfortable with artificial sweeteners

SlimFast reformulated its shakes to increase protein and reduce sugar while maintaining the dessert-like flavors that made them popular. The result is enjoyable to drink, though nutrition purists note the artificial sweetener content.

Key features

• Dessert-like flavors: Creamy vanilla, rich chocolate, and café latte varieties taste more like milkshakes than nutrition supplements. This improves adherence for people who struggle with clinical-tasting shakes
• Improved macronutrient profile: 20 g protein and 5 g fiber with only 1 g sugar, which is an improvement over the original SlimFast formulations.
• Wide availability: Found in nearly every grocery store and pharmacy, making it accessible and convenient

Pros

• Really enjoyable taste, doesn't require "getting used to"
• Convenient ready-to-drink bottles require no mixing
• Widely available at affordable prices
• Improved nutrition over original SlimFast (higher protein, lower sugar)

Cons

• Contains artificial sweeteners (sucralose, acesulfame potassium) that some prefer to limit
• Lower fiber (5 g) than top-rated options means less satiety for some people
• Brand association with older, less nutrition-focused diet shakes

Pricing

Varies depending on the product line. SlimFast Advanced Nutrition prices also fluctuate often in seasonal sales.

Bottom line

SlimFast Advanced Nutrition works well for people who've struggled with clinical-tasting shakes and need something enjoyable to drink consistently. The improved protein and reduced sugar make this a good option despite artificial sweeteners. 

7. Premier Protein meal replacement shakes

What it is: High-protein, low-sugar meal replacement at mainstream pricing

Who it's for: Budget-conscious consumers seeking high protein and good taste without premium pricing

Premier Protein delivers 30 g of protein, 1 g of sugar, and 160 calories at lower prices in comparison to boutique brands. The shakes taste good, mix well, and are available everywhere.

Key features

• High protein: 30 g protein per 29 is an excellent value compared to other premium options
• Wide availability: Sold at Target, Walmart, grocery stores, and pharmacies nationwide. No special ordering required.
• Variety of flavors: Vanilla, chocolate, café latte, caramel, and seasonal varieties prevent flavor fatigue.

Pros

• Well-reviewed taste, especially with café latte and caramel flavors 
• Ready-to-drink convenience with no mixing required
• Available in bulk at warehouse stores for further savings

Cons

• Lower fiber content (3 g) compared to top-rated options
• Contains artificial sweeteners (sucralose, acesulfame K)
• Less micronutrient profile than medical-grade options

Pricing

Premier Protein shakes are available in general grocery stores like Walmart and online at various price points.

Bottom line

Premier Protein offers a great value proposition for mainstream consumers who want high protein and low sugar without premium pricing. The taste is good, the protein content is high, and the availability is universal. Although it contains lower fiber and artificial sweeteners, it delivers good nutrition at accessible prices for budget-conscious weight management.

8. 310 nutrition shake

What it is: Very low-calorie meal replacement targeting women specifically

Who it's for: Those seeking light meal replacement or snack substitute rather than full meal replacement

310 Nutrition markets primarily to women with very low-calorie formulations (90-110 calories per serving). This works better as a snack replacement or light meal rather than a complete meal substitute for most people.

Key features

• Zero sugar with stevia: No added sugars and stevia sweetening, which appeals to those avoiding artificial sweeteners and sugar simultaneously
• Light texture: Thin, shake-like consistency that some prefer over thick, heavy meal replacements

Pros

• Zero sugar with natural stevia sweetening (no artificial sweeteners)
• Light, easy-to-drink texture
• Dessert-inspired flavors (salted caramel, vanilla cake) taste good

Cons

• Low protein (15 g) won't satisfy most people as a complete meal replacement.
• Higher price per serving relative to protein content.
• Marketing heavily toward women with specific body ideals may not appeal to all audiences.

Pricing

The 310 Nutrition shakes come in individual serving packs and various box sizes, with lower prices for bulk orders online.

Bottom line

310 Nutrition works best as a snack replacement or light meal supplement rather than a complete meal replacement for most people. The 90-calorie, 15 g protein serving won't provide sustained satiety for several hours. However, for those seeking a very low-calorie option to create substantial deficits or replace smaller eating occasions, it serves that purpose with decent taste and natural sweetening.

9. Soylent complete meal

What it is: Ready-to-drink balanced macronutrients and daily micronutrients with minimal preparation or thought required

Who it's for: Busy professionals who prioritize convenience and balanced macronutrients and 20-30% of daily micronutrient needs over taste 

Soylent emphasizes balanced macronutrients and convenience above all else. The ready-to-drink bottles require zero preparation, and the formulation provides balanced macronutrients and micronutrients without requiring any nutrition knowledge.

Key features

• Provides balanced macronutrients and 20-30% of daily micronutrient needs, zero prep: Pre-mixed bottles contain everything needed for a meal, no measuring, mixing, or cleaning required
• Balanced macronutrients: 20 g protein, 36 g carbohydrates (including 9 g sugar), and healthy fats provide sustained energy
• Original unflavored option: The original version has a neutral taste that allows customization or just functional consumption

Pros

• Ultimate convenience, grab a bottle and drink, no preparation
• Complete balanced nutrition for people who don't want to think about macros
• Neutral original flavor works for people who don't want sweet shakes
• Popular with tech workers and professionals who view eating as fuel

Cons

• Higher sugar content (9 g) compared to other options reviewed here.
• Higher calorie (400) requires portion awareness for weight management.
• Taste is functional rather than enjoyable for most people.
• Soy protein base may not suit those avoiding soy.

Pricing

Available on Soylent's website in packs of 12 or 36 servings. Prices vary depending on whether you buy online or in various health food stores.

Bottom line

Soylent serves people who view meals primarily as fuel and prioritize convenience over taste. However, higher sugar (9 g) and calories (400) make this less optimal for weight management compared to lower-calorie, lower-sugar options. It works best for maintaining weight while maximizing convenience rather than creating calorie deficits.

Can meal replacement shakes help with weight loss?

Research suggests that meal replacement shakes can support weight management when used appropriately and under clinical supervision. 

Results depend on baseline metabolism, total calorie intake, exercise, adherence, sleep quality, and hormonal health.

Why they may work for short-term calorie control:

• Portion control: Pre-measured servings provide you with accurate calorie intake
• Simplified decision-making: Reduces decision fatigue around food choices
• Protein-rich formulations: Higher protein intake promotes satiety and, when combined with adequate calorie intake and physical activity, supports lean muscle preservation during weight management
• Consistency: Regular use creates predictable calorie patterns that support deficit creation

Why whole foods still matter for long-term success:

• Satiety from chewing: The physical act of chewing and eating solid foods triggers satiety signals that liquids don't provide as effectively
• Nutrient complexity: Whole foods contain beneficial compounds (phytonutrients, polyphenols) that supplements can't fully replicate
• Eating skill development: Learning to build balanced meals with whole foods teaches sustainable habits for maintenance
• Social and cultural connection: Meals involve more than nutrition. They're part of social life and cultural identity

Meal replacements work best as transitional tools (3-6 months) rather than permanent solutions. Many patients find success using shakes for one meal daily while eating balanced, whole foods for other meals. This approach provides structure while maintaining the experience of preparing and eating solid food. 

The knownwell care team helps patients determine appropriate timing and duration for meal replacement use based on individual health status, goals, and preferences. 

What to look for in a weight loss shake

All meal replacement shakes do not have equal nutritional value. Use these criteria to evaluate options:

• High protein (20-30 g per serving): Protein promotes satiety. Combined with adequate calories and physical activity, protein preserves lean muscle during weight management. Look for complete protein sources: whey, casein, soy, or complementary plant proteins (pea + rice)
• Low added sugar (<5 g): Added sugars contribute calories without satiety benefits. Natural fruit sugars in small amounts are acceptable, but refined sugars or high-fructose corn syrup should be minimal. Check the ingredient list, not just the total sugar number. Some shakes use whole fruit, which provides fiber alongside natural sugars.
• Fiber content for satiety (at least 3-5 g): Fiber slows digestion and promotes fullness. Shakes with 5-9 g fiber per serving help you feel satisfied longer. Sources matter, so look for ingredients like chicory root fiber, inulin, or whole food fibers rather than isolated synthetic fibers alone.
• Vitamin and mineral profile: When replacing a meal, the shake should provide at least 20-30% of daily vitamin and mineral needs. Check for vitamins A, C, D, E, K, B-complex, and minerals, including calcium, iron, magnesium, and zinc.
• Taste and mixability: The best nutritional profile doesn't matter if you can't stand drinking it. Clinical-grade meal replacement formulated for use in medically supervised programs prioritizes nutrition over dessert-like flavors, while consumer brands focus on palatability. Consider your priorities and try small quantities before committing to large containers.

Red flags to avoid

• Excessive added sugar (>10 g) or artificial sweeteners in large amounts: High sugar content undermines weight management goals by spiking blood glucose without providing lasting satiety. While small amounts of artificial sweeteners are generally recognized as safe, excessive use may affect taste preferences over time, making naturally sweet whole foods taste less appealing.
• Low protein content (<15 g per serving): Shakes with minimal protein won't keep you satisfied or help preserve muscle mass. These function more like snacks than meal replacements
• Unclear ingredient sourcing or "proprietary blends": Vague ingredient lists make it impossible to assess quality. "Proprietary blends" hide actual amounts of individual ingredients, preventing informed decisions about what you're consuming.
• No fiber or healthy fats: Shakes lacking fiber won't promote fullness or support digestive health. Similarly, completely fat-free formulations may impair the absorption of fat-soluble vitamins (A, D, E, K) and leave you hungry shortly after drinking.
• No third-party testing or clinical use: Third-party testing verifies that products contain what labels claim and are free from contaminants. Shakes used in clinical settings have typically undergone more rigorous evaluation than direct-to-consumer brands.

Are meal replacement shakes safe for everyone?

While meal replacement shakes may be appropriate for many healthy adults when used as directed, individual tolerance and safety vary. Certain medical conditions require clinical oversight before use. 

Disclaimer: This information is for educational purposes only and does not constitute medical advice. Always consult your healthcare provider before starting any meal replacement program.

Some potential risks for people with specific health conditions include:

• Diabetes: Rapid-digesting carbohydrates in some shakes can spike blood glucose. People with diabetes need formulations with balanced macronutrients and adequate fiber. Those taking insulin or diabetes medications should consult their care teams before replacing meals with shakes, as calorie changes may require medication adjustments.
• Kidney disease: High protein intake stresses the kidneys in people with reduced kidney function. Medical supervision ensures protein intake stays within safe limits.
• Relapse in disordered eating: Meal replacements do not cause eating disorders, but they can trigger relapse of disordered eating behaviors in individuals with a history of these conditions. When used appropriately, meal replacements can still be a helpful tool, if incorporated within a supervised plan that emphasizes food variety, eating competence, and ongoing clinical or behavioral support.
• Nutrient gaps if overused or used without medical guidance: Replacing all meals with shakes for extended periods risks micronutrient deficiencies despite fortification. Whole foods provide nutrients and beneficial compounds that supplements can't fully replicate. Using shakes for all meals without clinical supervision is not advisable for most people.

Additionally, people taking medications for thyroid conditions, blood pressure, or blood thinning should discuss meal replacement timing with specialists, as changes in meal patterns can affect medication absorption or effectiveness.

When to seek medical guidance: Anyone with chronic health conditions, those taking multiple medications, pregnant or breastfeeding individuals, and people over 65 should consult healthcare professionals before starting meal replacement programs. Clinical supervision ensures safety and effectiveness.

How knownwell supports safe, sustainable weight management

Knownwell's approach to weight management centers on evidence-based care, which is customized to each patient's needs, medical history, and goals. Our board-certified obesity medicine care team understands that long-term weight management involves more than calorie reduction; it requires addressing the complex biological, psychological, and social factors that influence eating patterns and metabolism.

To achieve sustainable weight management, knownwell incorporates Robard clinical-grade meal replacement formulated for use in medically supervised programs into care plans when appropriate. These products meet rigorous nutritional standards and provide complete meal replacement with balanced macronutrients and micronutrients. 

Our care team will determine whether meal replacements fit your specific situation. Some patients benefit from structured meal replacement programs, while others achieve better outcomes with whole-food approaches. There's no single solution that works for everyone.

Our team also monitors your progress, adjusts recommendations based on your response, and addresses challenges as they arise. This supervision ensures meal replacements support your goals safely without leading to nutrient deficiencies or other complications.

Our regular check-in sessions allow our care team to assess:

• If current calorie and macronutrient targets remain appropriate
• How meal replacements affect satiety, energy, and overall well-being
• Whether medication adjustments are needed if you're taking weight management medications
• Progress toward health markers beyond just weight (blood pressure, glucose control, energy levels)

Our registered dietitians also help patients learn:

• Which meals to replace and which to eat as whole foods
• How to build balanced, whole-food meals that complement shake use
• When and whether to add supplemental vitamins or minerals
• How to adjust portions as weight and metabolic needs change

But remember, sustainability is highly individual, and using meal replacement shakes long-term isn't sustainable for everyone.​

Either way, we help patients stay away from risky or nutritionally inadequate options. The supplement market is largely unregulated, and many products make claims that exceed their actual benefits. The knownwell care team guides patients toward evidence-based options that meet nutritional standards while steering clear of products with questionable ingredients, excessive stimulants, or misleading marketing.

So, if you're considering adding meal replacements to your eating pattern, or if you're already using them and want to ensure you're doing so safely, consult with our care team.

Frequently asked questions

What is the best meal replacement shake for weight loss?

The best meal replacement shake for weight loss is Robard because it's formulated specifically for clinical weight management with balanced macronutrients and complete micronutrient profiles. 

Robard shakes provide 15-30 g protein (depending on product line), with sugar content ranging from 3-8 g depending on the specific formulation, adequate fiber, and 20-30% of daily vitamin and mineral requirements. They're used in physician-supervised programs nationwide and designed for extended use under professional guidance.

For other individuals, 'best' depends on dietary preferences, taste tolerance, and specific goals.

Are these shakes safe for long-term use?

Long-term safety depends on the specific shake and how you use it. Using shakes for one or two meals daily while eating balanced whole foods generally poses no safety concerns for healthy adults. 

Clinical-grade meal replacement formulated for use in medically supervised programs like Robard are designed for extended use. Replacing all meals with shakes for months without medical oversight is not advisable.

What's the best shake for women over 40?

The best shakes for women over 40 have at least 20g protein and 20-30% daily values of calcium and vitamin D. Orgain Organic Meal and Huel Black Edition both meet these criteria. Women over 40 need adequate protein to preserve muscle mass and calcium, and vitamin D for bone health.

Are vegan meal replacement shakes effective?

Yes, vegan (plant-based) meal replacements work just as well as dairy-based options when they provide complete protein with all essential amino acids. 

Quality vegan shakes use complementary proteins like pea combined with rice protein. Orgain Organic Meal, Ka'Chava, and Garden of Life Raw Organic Meal meet this standard.

Can I replace all three meals a day with shakes?

Replacing all meals with shakes is not advisable without medical supervision. Most people achieve better long-term outcomes using shakes for one or two meals while eating balanced, whole foods forthe  remaining meals. 

Note: Very low-calorie programs carry significant risks. Close monitoring does not eliminate risks of muscle loss, electrolyte imbalances, metabolic adaptation, and gallstones. 

Should I drink them before or after a workout?

Drinking shakes after exercise works best for most people, as it provides recovery nutrients while serving as a structured meal. Drinking shakes before intense exercise may cause digestive discomfort. 

For strength training, post-workout protein supports muscle recovery. For moderate cardio, timing matters less.

What's the best shake with low sugar?

The best shakes with low sugar include Orgain Organic Meal (1 g), Huel Black Edition (1 g), Premier Protein (1 g), and 310 Nutrition (0 g) that contain minimal sugar. If you prefer avoiding artificial sweeteners, choose options sweetened with stevia or monk fruit, like Orgain.

How do I choose between plant-based and whey protein?

Whey provides complete amino acids naturally with a smooth texture. Plant protein suits vegan eating patterns, has a lower environmental impact, and works for those with lactose intolerance. 

From a weight management perspective, both can be equally effective when providing adequate total protein. Choose based on dietary preferences and what you'll drink consistently.

Do I need a doctor's approval to use these?

Healthy adults generally don't need approval for occasional use. Consult a physician if you have diabetes, kidney disease, heart conditions, take multiple medications, plan to replace more than one meal daily for extended periods, are pregnant or breastfeeding, have a history of eating disorders, or are over 65 or under 18.

Can shakes be used with GLP-1 medications like Ozempic?

Meal replacement shakes may be used alongside GLP-1 medications, but this requires close coordination with your care team. GLP-1 medications significantly reduce appetite, which can make meeting protein and nutrient needs challenging. 

Your health care professional needs to monitor your total intake to ensure adequate nutrition while avoiding excessive calorie restriction that could lead to muscle loss or nutrient deficiencies. 

Timing of shakes may also need adjustment to minimize GI side effects. Never start meal replacements while on GLP-1 medications without discussing with your care team first. For specific guidance, read our article on what to eat while taking Zepbound.
