Rev Up Your Metabolism with Foods That Have a High Thermic Effect
Medically Reviewed by Dr. Nicole Avena

Are you looking to burn more calories without even breaking a sweat?

If so, we’ve got a top health tip for you.

Below, we’ll uncover which foods have the highest thermic effect to help rev up your metabolism.

What Is the Thermic Effect?

The thermic effect of food (TEF)¹ is the change in metabolic rate that occurs after eating. It refers to the amount of energy expenditure that’s required for the digestion, absorption, and storage of nutrients from food. The TEF is a component of total daily energy expenditure (TDEE),² which also includes resting metabolic rate and physical activity.

The process of digestion requires energy to break down food into smaller molecules that can be absorbed by the body. This accounts for most of the TEF. Also, energy is required for the storage of nutrients and the utilization of nutrients once they’ve been absorbed into the body.

In general, protein has a higher thermic effect compared to carbohydrates and fats. This means that consuming a meal high in protein can result in a greater increase in metabolic rate compared to a meal lower in protein with the same number of calories.

Research has shown that the TEF can account for around 10% of daily energy expenditure for most people, but this can vary depending on dietary intake and individual variances. Certain factors, such as age and body composition, can influence the TEF. Also, the TEF may vary based on the type and amount of food consumed, as well as individual metabolic differences.

It’s important to note that the TEF is a small component of overall energy expenditure and may not significantly contribute to weight loss. However, if you’re looking for natural ways to stoke your metabolism, even small gains from the TEF may be beneficial to your overall health and well-being.

Here Are Some of the Top Foods with a High Thermic Effect

Lean Protein

When it comes to foods with a high thermic effect, lean proteins are at the top of the list. Consider chicken breast, turkey, or fish – these options require more energy for your body to digest and metabolize compared to other food groups. This means that by simply incorporating lean proteins into your meals, you can boost calorie burning throughout the day.

Not only are lean proteins great for increasing the thermic effect of food, but they also help keep you feeling full and satisfied. This can aid in weight management and help prevent overeating. So, the next time you’re planning a meal, consider adding some grilled chicken or salmon for an extra metabolic kick.

Remember that variety is key when it comes to optimizing your thermic effect and overall metabolism. Mix up your protein sources throughout the week to ensure you’re getting a wide range of nutrients.

Spicy Foods

Spicy foods can be a tremendous asset in helping you burn calories. The thermic effect of spicy foods come from compounds like capsaicin found in chili peppers, which can help fire up your metabolism.

These spicy ingredients not only add flavor to meals, but also increase the heat production in your body, leading to a temporary spike in calorie expenditure.

Whether you enjoy Mexican cuisine with jalapeños or Indian dishes with curry powder, incorporating spicy foods into your diet can help enhance the thermic effect of what you eat.

Fruits and Vegetables

Fiber-rich fruits and vegetables are essential for overall health and can play a key role in supporting your metabolism through the thermic effect. These foods may require more energy to digest, leading to a higher calorie burn during the digestion process. Berries, apples, broccoli, and spinach are excellent choices as they’re packed with fiber that can keep you feeling full longer, while aiding in digestion.

Adding colorful fruits, like oranges or strawberries, to your morning smoothie can help kickstart your day. For lunch and dinner, incorporate leafy greens like kale or Brussels sprouts into salads or stir-fries for a delicious way to increase your metabolic rate naturally.

By including fiber-rich fruits and vegetables in every meal you’re not only supporting weight management, but also promoting better digestion and nutrient absorption.

So, the next time you’re at the grocery store, load up on nutrient-rich produce to help maximize the thermic effect of your diet.

Green Tea and Caffeine

Green tea and caffeine can have a significant impact on boosting the thermic effect of food. Green tea is rich in antioxidants like catechins,³ which may help increase metabolism and promote fat oxidation. Caffeine, found in coffee and other beverages, also can help enhance calorie burning.

Both green tea and caffeine can help increase energy expenditure during digestion, leading to a higher thermic effect after meals. Incorporating these into your diet can be as simple as starting your day with a cup of green tea or enjoying a post-workout coffee.

It’s important to note that while these beverages can aid in calorie burning, moderation is key. Too much caffeine intake may lead to side effects like jitteriness or disrupted sleep patterns. For optimal results, make sure to monitor your consumption levels and be mindful of your body’s cues when including green tea and caffeine in your daily routine.

By incorporating these foods and beverages strategically into your meals and snacks each day, you can maximize the thermic effect of food and help support your weight management goals.

Other Factors That Can Impact the Thermic Effect

Meal Frequency

Meal frequency may play a role in the thermic effect and the process of burning calories. Eating smaller, balanced meals throughout the day can help keep your metabolism active and prevent energy slumps. Aim for regular intervals between meals to optimize this effect.

Regular Exercise

Exercise is another key factor that can impact your body’s ability to efficiently burn calories. Both aerobic and strength training exercises can increase your metabolic rate, leading to higher calorie expenditure. Incorporating physical activity into your routine is essential for maximizing the thermic effect.

Quality Sleep

Though often overlooked, quality sleep is crucial for maintaining a healthy metabolism. Lack of sleep can disrupt hormone levels related to appetite regulation⁴ and energy balance, potentially slowing down your body’s ability to burn calories effectively. Getting sufficient sleep each night, 7-9 hours is recommended, can help support the thermic effect and your overall well-being.

Optimize the Thermic Effect

Incorporating foods with a high thermic effect into your diet can help burn calories and support your weight loss goals.

Remember to include lean protein with every meal to increase satiety, which can aid in weight management. Focus on meal frequency to keep your metabolism active throughout the day.

Also, don’t forget the importance of regular exercise and quality sleep in supporting overall metabolic function.

By incorporating these tips into your lifestyle, you can optimize the thermic effect of food to burn calories naturally.
