Discover the benefits of eating nuts for weight loss. Learn how to incorporate nuts into your diet for optimal results using Noom’s personalized approach.

What you’ll learn:

  • Nuts are packed with protein, healthy fats, and fiber, which can help you feel satisfied, making them a good tool for weight loss in moderation.
  • Portion control and factoring nuts into your daily calorie count is important because nuts are high in calories and fat. 
  • Nuts also contain healthy fats, like omega-3s, which support heart health. 

Can nuts be a part of a weight loss plan? Absolutely! Including a variety of nuts in your weekly diet, along with a calorie deficit, can contribute to weight loss. Nuts are packed with protein, fiber, and healthy fats, offering a satisfying crunch and helping you feel full and energized throughout the day. 

Just don’t go overboard. Even though nuts can be satisfying, they also have a high-calorie content—this is why Noom classifies nuts as an orange food. Orange foods are the most calorie-dense and should be eaten less frequently and in smaller portions. 

Let’s explore how to incorporate them into your day to achieve the best results for your health and weight and how Noom can help.

Can nuts help you lose weight?

Nuts are rich in healthy fats, protein, and fiber—a combination that can help you feel satisfied, leading you to eat fewer calories. 

Research has shown that eating about one handful of nuts daily (about an ounce) can help you manage your weight and prevent weight gain as you age. The combination of fiber and protein in nuts may keep you full and help prevent overeating. 

Remember, portion control and tracking the amount of nuts you eat is key. By including a moderate amount of nuts in your meals and snacks throughout the week, you can enjoy their satisfying crunch and flavor while still losing weight.

Can nuts boost your metabolism?

No, nuts don’t directly boost your metabolism. However, they are rich in minerals like magnesium and selenium, which play important roles in supporting metabolic function. Studies show that eating nuts in moderation does not contribute to weight gain and may even help with weight management due to their ability to promote satiety and reduce overall calorie intake.

Remember, everyone’s needs are different. With the right approach, these nutrient-dense snacks can be valuable in your weight management toolkit.

How many nuts should I eat per day? 

A single one-ounce serving a few days per week is recommended, and you should factor that into your daily calorie needs. The trick to eating nuts is to master portion control. Here are some tips so that you don’t overdo it:

  • Aim for about one ounce (28 grams) per serving, which is roughly:
  • 49 pistachios (in shells): 160 calories
  • 24 almonds: 164 calories
  • 18 cashews: 157 calories
  • 14 walnut halves: 185 calories
  • 10-12 macadamia nuts: 200 calories
  • Use a small container or snack-sized bag to pre-portion your nuts.
  • Use a food scale until you can eyeball portions accurately.

Are nuts high in fat?

While nuts are somewhat high in fat, much of it is unsaturated. These “healthy” fats, including monounsaturated and polyunsaturated fats, play a crucial role in lowering LDL (or “bad”) cholesterol, supporting heart health, and supplying essential fatty acids that the body can’t produce on its own.

Unsaturated fats have been linked to a lower risk of heart disease and better overall cardiovascular health. Some nuts, like walnuts, are especially noteworthy as they contain omega-3 fatty acids. These beneficial fats promote heart health, strengthen cell membranes, and may even enhance brain function.

Fun fact: Walnuts are one of the richest plant-based sources of omega-3s.

Healthy ways to add nuts to meals and snacks

Now that you’ve discovered the health benefits of nuts, let’s explore how to integrate them into your meals and snacks. One good tip is to swap out other high-calorie toppings or snacks for nuts. For example, try slivered almonds instead of croutons on salads, a handful of roasted pistachios instead of potato chips, or chopped walnuts instead of granola on yogurt. 

Breakfast

Starting your day with nuts can set you up for success. Nuts give you essential nutrients that help you stay focused and provide stable energy throughout the day. The fiber and healthy fats in nuts can help you feel full longer, regulating your appetite. 

Easy ways to incorporate nuts into your breakfast
  • Add a sprinkle of chopped nuts to your bowl of oatmeal or yogurt for a little crunch and healthy fat. 
  • Add a tablespoon of nut butter to a smoothie for extra protein and flavor.

Lunch

When added to lunch, the protein and healthy fats in nuts may help curb cravings that lead to unhealthy snacking later in the day.

Easy ways to incorporate nuts into your lunch
  • Toss a few toasted walnuts on salads or add chopped hazelnuts to a grain bowl. 
  • Use them to replace croutons for a great crunch with more nutrients.

What’s the best nut for weight loss?

There is no single “best” nut for weight loss. If you track your calories and eat in moderation, all nuts can be part of a healthy diet. Each type of nut has its health benefits. You can eat a variety of nuts as part of your weight loss plan as long as you’re mindful of your portions and keep your calorie intake in check. Here’s how common nuts compare ounce for ounce:

  • Cashews (155 calories) are rich in heart-healthy monounsaturated fats. They can also give a creamy texture to dairy-free sauces and snacks. 
  • Hazelnuts (178 calories) – Hazelnuts are packed with healthy fats, fiber, and antioxidants, particularly vitamin E, which promotes skin health. 
  • Almonds (160 calories) – Almonds can help you feel full and are high in fiber and vitamin E. 
  • Pistachios (160 calories) – You’ll get more nuts per serving with pistachios because they have fewer calories per nut. Plus, peeling off those shells reduces how quickly you can eat them. 
  • Peanuts (161 calories) – Though technically a legume, peanuts are usually treated like nuts. They are an excellent source of healthy monounsaturated fats and may help lower cholesterol.
  • Walnuts (185 calories) –  As mentioned, walnuts are abundant in heart-healthy omega-3s. A study found that incorporating walnuts into a reduced-calorie diet led to weight loss and cardiovascular benefits, including improved LDL cholesterol levels and lower blood pressure.
  • Brazil nuts (190 calories)  Brazil nuts are rich in antioxidants, particularly selenium. These compounds have powerful antioxidant and anti-inflammatory properties that may help reduce the risk of heart disease and cancer.
  • Pine nuts (191 calories) – Pine nuts are a good source of magnesium, which can help reduce muscle cramps and fatigue.
  • Pecans (196 calories) – Pecans are one of the highest-calorie nuts per one-ounce serving, but they’re loaded with antioxidants and healthy monounsaturated fats. A study suggests that eating a handful of pecans daily in exchange for other fatty foods may promote improved cardiometabolic health.
  • Macadamia nuts (204 calories) – Because macadamia nuts have more calories per serving, portion them carefully.
