The best nuts for weight loss provide protein, healthy fats, and fiber in small packages that may help you feel satisfied for longer.
Are nuts healthy for weight loss? Research showed that daily nut consumption improves metabolic markers such as fasting blood sugar, lipid profile, and glycemic control, some of which may contribute to weight management outcomes.
Nuts have a high caloric density, meaning that just a handful packs plenty of energy. Pay attention to portion sizes when including nuts in your eating pattern. Pre-measure nuts and pack them as a snack rather than eating them out of a bag.
Disclaimer: Always consult with your physician or healthcare provider regarding your individual nutritional needs. Everyone's dietary requirements for a balanced eating pattern differ.
Nuts may help with weight management by providing protein, fiber, and healthy fats that can help you feel full and satisfied. This may help reduce cravings and unnecessary snacking for many people.
They also offer essential nutrients your body needs for energy and hormone function. Pay attention to portion sizes since nuts contain a high number of calories.
Nuts deliver powerful nutrition in small servings. A 1 oz handful (about 23 almonds or 14 walnut halves) provides healthy monounsaturated fats, plant-based protein, and fiber that work together to support satiety.
Protein and fiber may slow digestion for some people, which can help you feel full between meals. Slowing digestion may reduce cravings and prevent mindless snacking between meals for some people.
The healthiest nuts to eat typically contain fiber, protein, and healthy fats.
What are the healthiest nuts to eat for weight management? Nuts that provide at least 4g protein, 2g fiber, and predominantly unsaturated fats per 1 oz serving work well for most people. Top choices include almonds, pistachios, and walnuts.
Healthy fats support hormone production and help your body absorb fat-soluble vitamins. Your body needs these fats to function properly. Nuts provide healthy fats with less saturated fat than many animal products, making them a helpful addition to varied eating patterns.
Portion control can be helpful for many people's weight management goals. Nuts provide significant energy because of their caloric density. A 1 oz serving gives you nutritional benefits while fitting into your daily calorie needs.
Ultimately weight management largely depends on maintaining a sustainable caloric balance that works for your individual needs.
The best nuts for weight management offer a balance of protein, fiber, and healthy fats that may help you feel full.
Disclaimer: We ranked nuts by their nutritional value, satiety, and other added health benefits. But individual needs vary, and you should consult with your healthcare provider about which foods work best for your personal health goals.
Why they may help: High protein and fiber content may promote lasting fullness
Nutrition per 1 oz: 164 calories, 14 g fat, 6 g protein, 4 g fiber
Almonds contain more protein than most nuts, making them helpful for maintaining muscle mass during weight management. The combination of protein and fiber may help support blood sugar regulation for some people, potentially preventing energy crashes that trigger cravings.
Almonds for weight loss are among the healthiest nuts you can choose, thanks to their protein and fiber content.
A randomized trial found that participants who replaced carbohydrate-rich snacks with almonds as part of a calorie-controlled diet experienced improvements in weight management and heart health markers. However, the study indicates that it is the overall calorie control, rather than almonds alone, that primarily contributed to weight loss.
All this makes almonds a smart combination for heart-healthy snacking.
How to eat them: Add sliced almonds to salads, oatmeal, or Greek yogurt for extra crunch.
Caution: Raw almonds provide the most benefits. Flavored varieties contain added oils, sugar, or excess salt.
Why they may help: The act of shelling slows eating and prevents overeating when coupled with deliberate portioning
Nutrition per 1 oz: 159 calories, 13 g fat, 6 g protein, 3 g fiber
Pistachios offer a unique advantage for weight management. The process of shelling each nut naturally slows your eating pace, giving your brain time to register fullness. The visual cue of empty shells also helps you track how many you ate.
A 2011 study found people consumed 41% fewer calories eating in-shell pistachios (125 calories) compared to shelled ones (211 calories), likely because shelling slows eating and increases perceived volume, despite similar fullness and satisfaction.
How to eat them: Buy them in shells and enjoy them as a snack or as an addition to salads and yogurt. Cracking each one can make eating more intentional.
Caution: Salted pistachios can encourage overconsumption. Choose unsalted varieties when possible to limit excess sodium.
Why they may help: Omega-3 fatty acids lower triglycerides, thus improving heart health. It also reduces inflammatory processes.
Nutrition per 1 oz: 185 calories, 18 g fat, 4 g protein, 2 g fiber
Walnuts provide more omega-3 fatty acids than any other nut. These healthy fats support brain health and may help regulate appetite hormones for some people. The anti-inflammatory properties of omega-3s can support overall metabolic health.
A 2025 study found that consuming less than 40 g of walnuts daily (about 1.4 oz) was associated with reductions in both BMI and body weight, making walnuts a helpful addition to a balanced eating pattern.
How to eat them: Chop walnuts and sprinkle over salads or mix into homemade granola for a heart-healthy crunch.
Caution: Walnuts have the highest calorie content per ounce. Stick to measured portions to maintain calorie balance.
Why they may help: Lower in fat than most nuts while providing satisfying creaminess
Nutrition per 1 oz: 157 calories, 12 g fat, 5 g protein, 1 g fiber
Cashews contain less fat than many popular nuts (12 g per ounce vs. 14 g in almonds and 18 g in walnuts) while still providing protein and satisfaction.
Cashews provide magnesium, a mineral that supports many body functions. Adequate magnesium intake maintains nerve and muscle function, boosts the immune system, and may contribute to better sleep quality, though individual needs vary.
How to eat them: Use raw cashews to make dairy-free cream sauces or enjoy a handful as an afternoon snack.
Caution: People often overeat cashews because of their mild flavor and smooth texture. Pre-portion servings to maintain control.
Why they may help: Rich in healthy fats that may promote satiety with smaller portions
Nutrition per 1 oz: 196 calories, 20 g fat, 3 g protein, 3 g fiber
Pecans provide predominantly monounsaturated fats, the same heart-healthy fats found in olive oil and avocados. These fats may help you feel satisfied with smaller portions and are part of heart-healthy eating patterns.
Pecans contain antioxidants that may support overall health, though individual responses vary.
How to eat them: Toast pecans lightly to enhance their natural nutty flavor, then add to salads or eat as a measured snack.
Caution: Pecans are calorie-dense, so pay attention to portion sizing.
Why they may help: High healthy fat content
Nutrition per 1 oz: 204 calories, 21 g fat, 2 g protein, 2 g fiber
Macadamia nuts contain the highest percentage of monounsaturated fats among all nuts. This makes them potentially very satisfying for many people. A measured portion may provide lasting fullness.
The rich, buttery flavor feels indulgent, and the healthy fats in macadamias may help some people feel satisfied, potentially supporting balanced eating patterns.
How to eat them: Enjoy 6-8 macadamia nuts as a luxurious snack, or chop them to add richness to baked goods in small amounts.
Caution: Macadamias contain the most calories per serving of any nut.
Why they may help: Good source of vitamin E and fiber for metabolic support
Nutrition per 1 oz: 178 calories, 17 g fat, 4 g protein, 3 g fiber
Hazelnuts provide vitamin E, an antioxidant that supports immune function and protects cells from oxidative damage. The fiber content helps with digestion and may promote feelings of fullness for some people.
Their naturally sweet flavor can satisfy cravings for sweeter foods without added sugars.
How to eat them: Add chopped hazelnuts to morning oatmeal or blend them into smoothies for extra creaminess and nutrition.
Caution: Many hazelnut products contain added sugars. Choose raw or dry-roasted varieties without flavoring.
Why they may help: Selenium content supports thyroid function and metabolism
Nutrition per 1 oz: 186 calories, 19 g fat, 4 g protein, 2 g fiber
Brazil nuts are rich in selenium, a trace mineral that supports thyroid function. While adequate selenium supports health, individual nutritional needs vary. Consult your physician if you have thyroid-related concerns.
Just one Brazil nut can provide about 77 percent of the daily selenium needs for most adults, though amounts vary by nut size and source.
How to eat them: Consume 1-2 Brazil nuts per day as part of a balanced mixed nut serving, or add small amounts of chopped Brazil nuts to a trail mix.
Caution: Excessive selenium intake can lead to toxicity (selenosis). Consult your physician if you have thyroid conditions or take selenium supplements.
Why they may help: Pinolenic acid may help support natural appetite regulation
Nutrition per 1 oz: 191 calories, 19 g fat, 4 g protein, 1 g fiber
Preliminary research suggests that pine nuts contain pinolenic acid, a polyunsaturated fat that may influence appetite-regulating hormones. However, individual responses require more research.
Pine nuts also provide magnesium, which may support healthy sleep and stress management.
How to eat them: Toast pine nuts lightly and sprinkle them over salads, pasta, or roasted vegetables for Mediterranean flavor.
Caution: Pine nuts cost more than many nuts. Use them as a flavorful garnish rather than a main snack.
Why they may help: Technically legumes, but provide similar benefits with more protein
Nutrition per 1 oz: 161 calories, 14 g fat, 7 g protein, 2 g fiber
Peanuts offer more protein than many tree nuts, making them helpful for maintaining muscle mass during weight management. The combination of protein, healthy fats, and fiber may provide sustained energy and satisfaction for many people.
Peanuts also contain resveratrol, the same antioxidant found in red wine.
How to eat them: Choose dry-roasted peanuts without added oils or salt. Add to stir-fries or enjoy a small handful as a protein-rich snack.
Caution: Peanut allergies are common. Many commercial varieties add oils, salt, or sweeteners that significantly increase calories.
Why they may help: Lower in fat and calories while providing complex carbohydrates
Nutrition per 1 oz: 63 calories, 1 g fat, 1 g protein, 2 g fiber
Chestnuts differ significantly from other nuts. They contain less fat and calories while providing complex carbohydrates. This makes them more similar to starchy vegetables than traditional nuts.
The fiber and complex carbs may provide steady energy without the calorie density of other nuts.
How to eat them: Roasted chestnuts make a warming snack during colder months, or add them to soups and stews for texture.
Caution: Fresh chestnuts need proper preparation to be safe to eat. Buy pre-roasted versions or learn proper cooking techniques.
Why they may help: Variety prevents boredom and provides diverse nutrients
Nutrition per 1 oz: ~170 calories (varies by mix), mixed fat profile, 5-6 g protein, 2-3 g fiber
Mixed nuts provide nutritional variety and can help prevent boredom with eating the same foods repeatedly. The combination of different textures and flavors can make snacking more satisfying for many people.
You benefit from the unique compounds found in each type of nut.
How to eat them: Choose mixes without dried fruit, chocolate, or excess salt. Create your own blend to control ingredients and portions.
Caution: Commercial mixes may include extra oils, salt, or sweetened additions that increase calories significantly.
Some nuts have added sugars, oils, and salt that make them less supportive of health goals than others. Choose raw or dry-roasted nuts over flavored or coated ones to get the benefits without the drawbacks.
Honey-roasted, chocolate-covered, or cinnamon-sugar varieties can contain as many calories as candy while masking the natural satisfaction that plain nuts may provide.
Salted nuts contribute excess sodium that can cause water retention and may interfere with natural hunger cues for some people. Added salt enhances flavor in ways that can encourage overeating.
The salty taste may trigger cravings and override natural fullness signals, making portion control more challenging for many people compared to unsalted varieties.
Trail mixes frequently include chocolate chips, dried fruit with added sugar, or other high-calorie additions that can triple the calorie content while reducing the protein and fiber density.

Most adults can include around 1 oz (about 23 almonds, 14 walnut halves, or 18 cashews) in a balanced eating pattern for weight management. However, everyone has different caloric and nutritional needs.
You can divide this into smaller portions throughout the day or enjoy it as one satisfying snack. Individual needs vary significantly, so consult with your care team about what amounts work for your specific health goals.
Peanuts provide healthy fats, protein, and fiber that are supportive of health goals and may support weight management when eaten in appropriate portions for your individual needs.
While peanuts are calorie-dense like all nuts, the protein and fiber may help some people feel satisfied with smaller amounts. Choose unsalted, dry-roasted peanuts to limit unnecessary additives.
Your registered dietitian can help determine if peanuts fit well into your personal eating pattern.
Chestnuts are the lowest-calorie nut at just 63 calories per ounce, but they're quite different from other nuts in texture and nutritional profile. Among traditional nuts, cashews and almonds are lower-calorie options at around 160 calories per ounce.
Remember to consider calorie content alongside protein, fiber, and healthy fat content when choosing foods that support your health goals.
The healthiest nuts for weight loss include almonds, pistachios, and walnuts because they have over 4 g of protein, 2-4 g of fiber, and heart-healthy unsaturated fats in 1 oz. These nutrients work together to promote fullness without excessive calories.
However, the right choice depends on your individual taste preferences, portion control needs, and overall eating pattern.
Remember to consider calorie content alongside protein, fiber, and healthy fat content when choosing foods that support your health goals.
Nut butters can fit into a weight management plan when you measure portions carefully and consider your individual calorie needs. Two tablespoons contain about the same calories as an ounce of whole nuts, but may satisfy you less.
Choose natural varieties without added sugars or oils, and measure servings rather than eating directly from the jar. Discuss with your dietitian how nut butter portions might fit into your personalized eating plan.
Yes, nuts are healthy for weight loss when eaten in appropriate portions. Daily nut consumption doesn't cause weight gain when portions fit within your overall calorie and nutrition needs.
Some research suggests people who include nuts in balanced eating patterns may maintain healthier weights, though individual results vary.
The key is eating appropriate serving sizes consistently. Your individual response may vary based on your metabolism, activity level, and overall eating pattern. Work with your healthcare team to determine what works for you.
Consider limiting nuts with added sugars, excess salt, or oil coatings rather than avoiding any specific type of nut.
Flavored varieties like honey-roasted or chocolate-covered nuts can contain double the calories of plain varieties. Focus on raw or dry-roasted options without additives.
Your dietitian can provide personalized guidance about which nuts work well for your individual health goals and any specific dietary considerations.
Most nuts fit well into low-carb eating patterns due to their high fat and protein content, with minimal carbohydrates.
Pecans, macadamias, and Brazil nuts have fewer carbs, while cashews contain slightly more carbohydrates than other nuts, so portions may need adjustment on very low-carb plans.
Consult with your registered dietitian about how nuts fit into your specific eating pattern and health goals.
Nuts can work well as pre-workout fuel when you eat them 30-60 minutes before exercise, providing sustained energy from healthy fats and protein for some people.
They may also support recovery when you pair them with a carbohydrate source after workouts. Individual responses vary significantly.
The timing matters less than finding what works well for your digestion, energy levels, and overall eating plan. Discuss timing with your registered dietitian if you have specific performance or health goals.
