6 best foods to help boost your metabolism



Possibly. What we eat can help influence our metabolic process and make it a little more or a little less efficient. But before you overhaul your diet, it’s necessary to understand how your metabolism functions.

What Is Metabolism and How Does It Work?

“Your metabolism is what’s in control of your body and how it makes and burns energy from food,” says Melissa Majumdar, RD, a senior bariatric dietitian for the Brigham and Women’s Center for Metabolic and Bariatric Surgery in Boston and a spokesperson for the Academy of Nutrition and Dietetics. “We rely on our metabolism to do everyday activities but also to breathe, think, digest, circulate blood, and regulate temperature,” she explains.

Metabolism consists of our resting metabolic rate (RMR), which is the energy our body uses to breathe, circulate blood, and perform other basic functions; activity thermogenesis, which is any type of activity or exercise; and the thermal effect of food. “By just eating, we’re burning calories to turn that food into energy,” Majumdar explains.

Each one of these factors makes up a typical percentage of the total energy expenditure, but there is some variability. For most people, thermogenesis makes up about 10 percent of their total energy expenditure, while resting metabolic rate accounts for about 60 to 70 percent. The most variability occurs with activity levels and can vary from 100 calories burned for a sedentary person to up to 3,000 calories or more for a training athlete.

What Affects Our Metabolism, for Better or Worse?

Genetics play the biggest role in metabolism, but some variations are seen among certain ethnic groups.

Lean muscle mass, which accounts for about a 5 percent difference between men and women, also affects metabolism, because muscle burns more calories than fat, even at rest. Increasing muscle mass through exercise increases your metabolism even when you’re not actively exercising.

The most variability in metabolism among individuals is also seen with activity thermogenesis (the number of calories you burn by being active).

How Does Eating Certain Foods Help Rev Up Your Metabolism?

Certain foods can speed up or slow down metabolism, potentially affecting weight loss. But it’s not a simple, direct relationship — “eat this to boost your metabolism and lose weight.”

For example, meals high in protein cause our metabolism to increase, but it’s usually temporary. “At that meal, your energy expenditure is greater,” says Majumdar. “Whether that actually translates to big changes, weight management, or weight loss is a different story.”

What’s more, with respect to weight loss, metabolism isn’t the only factor; the amount we eat also matters. Eating meals high in protein, fiber, and healthy fats promotes satiety, meaning we’re less likely to eat as much at the next meal.

On the flip side, not eating enough calories can cause your body to use muscle for energy, which can lead to a loss of muscle mass. If the body is trying to reserve its energy stores, metabolism will slow.

Experts agree that there’s no one food that will have such a significant effect on our metabolism that it would cause us to lose weight. But there are foods that may rev up your metabolism a bit, and there are others you should eat in moderation or avoid altogether.

Six of the Best Foods to Help Boost Your Metabolism

1. Avocado


Avocado is high in healthy polyunsaturated and monounsaturated fats, which promote satiety. A study published in November 2013 in Nutrition Journal found that adding half an avocado at lunch may help overweight people feel more satisfied and reduce their desire to eat in the hours following a meal.

Since avocado is an anti-inflammatory food, it may have a secondary effect. “Inflammation can definitely interfere with a lot of different things in your body, one of which might be metabolism,” says Lisa Moskovitz, RDN, the CEO of the New York Nutrition Group in New York City.

If you’re trying to lose weight, be mindful of portion sizes. One quarter of an avocado has 80 calories and 8 grams of fat.

2. Tempeh


High in protein and fat, tempeh promotes satiety — a feeling of fullness. Since the soybeans it’s made with are fermented, tempeh contains probiotics, which can be beneficial for gut health and may improve immunity. “When all that is running well, it can help you have more energy and burn more calories,” Moskovitz says.

A meta-analysis published in May 2017 in the journal Microbial Pathogenesis suggests that adults who take probiotic supplements may lose weight; the review did not attribute this to a direct increase in metabolism. It’s important to note that research on the link between probiotics, gut health, and weight is still preliminary. Many more studies are needed before probiotics in food or supplement form can be recommended for weight loss or healthy weight maintenance.

3. Chili pepper

Chili peppers

Studies show that eating spicy foods like chili peppers may help speed up metabolism. A meta-analysis published in June 2017 in the journal Bioscience Reports found that capsaicin, an active compound found in chili peppers, helps to speed up metabolism and may play a role in weight loss as a result. The studies included in the analysis used capsaicin supplements, so it cannot be assumed that capsaicin-containing foods (which have lower amounts of the compound than concentrated supplements do) would have the same affect on metabolism.

4. Beans


Beans are an excellent source of protein to keep you feeling satiated — and amino acids, the building blocks of protein, can help preserve muscle mass and thus burn more calories while your body is at rest. “Foods that promote or preserve lean muscle mass are always good for metabolism,” Moskovitz says.  

Additionally, the fiber in beans helps to fill you up with fewer calories so you can go for a longer time between meals or eat less overall.

Eating ¾ of a cup each day of beans or legumes was found to contribute to just over half a pound of weight loss over about six weeks, according to a systematic review and meta-analysis published in September 2016 in the American Journal of Clinical Nutrition. Although half a pound itself isn’t a huge amount, adding beans and legumes to your diet may help you lose weight and prevent you from gaining it back, the authors noted.

5. Whole grains

Whole grains

Unlike refined grains, whole grains contain fill-you-up fiber, are anti-inflammatory, and may be beneficial for weight management. A study published in March 2017 in the American Journal of Clinical Nutrition suggests that swapping whole grains for refined grains may result in a “modest increase” in resting metabolic rate. Study participants who substituted whole grains for refined also had increased calorie loss during digestion.

6. Eggs


Eggs are not only low in calories, but because they’re an excellent source of protein and some healthy fat, they stave off hunger. They’re also a good source of B vitamins, which have been shown to boost metabolism. “B vitamins help convert the foods you eat into energy, so they help with processing those calories better and using them for energy,” Moskovitz says.

Research published in the International Journal of Obesity looked at overweight and obese adults over an eight-week period. Two sets of participants went on a diet that reduced their energy intake by 1,000 calories a day. One of these groups ate two eggs for at least five days a week for breakfast and the other group consumed the same amount of calories but ate bagels. The egg eaters lost 65 percent more body weight, 16 percent more body fat, had a 61 percent greater reduction in body mass index (BMI) and a 34 percent greater reduction in waist circumference. (The study also looked at two other groups of participants, who did not go on a reduced-calorie diet but followed the same egg or bagel plan. No statistical differences in weight or fat loss were shown between these sets.)
