The 11 Best Foods to Boost Your Metabolism. By Alina Petre, MS, RD NL. Can I Use Vitamins for Weight Loss? Medically reviewed by Sirisha Yellayi, DO.

Can 7-Keto-DHEA Supplements Boost Your Metabolism? The rate at which the body burns calories to produce this energy is called the metabolic rate. Scientists use various formulae to measure resting metabolic rate RMR , also known as resting energy expenditure REE.

RMR and REE refer to the amount of energy a body uses at rest, for example, sleeping or sitting. The rate can vary between individuals. Factors affecting it include age, sex, and the activity the person is carrying out at the time.

While a person has no control over the genetic aspects of their metabolism, research shows that some strategies may help speed up the rate at which the body processes calories.

It is worth noting that, while speeding up the metabolism may help people burn calories and lose weight, it needs to be part of an overall strategy that includes a healthy and varied diet and regular exercise. The authors also hypothesized that meal timing may play a role in resting energy expenditure.

However, the results were not conclusive, and more reseach is needed. Learn about time-restricted eating , which focuses on the timing of meals to improve health and gain muscle. Some people skip meals as a way to lose weight.

However, this can negatively impact metabolism. Eating meals that are not filling can have the same effect. According to current dietary guidelines, adult females aged 19 and over need 1,—2, calories a day, depending on their physical activity levels, and males need 2,—3, During pregnancy and breastfeeding, females will need up to additional calories, depending on the stage.

How many calories should I eat per day? Reducing calories may not increase metabolic rate, but the choice of foods that provide those calories may do.

Protein, for example, may be more likely than carbohydrates or fat to promote thermogenesis, the burning of calories in the body. Those who consumed a higher proportion of protein burned more energy than those who consumed less. Some research has suggested that green tea extract may play a role in promoting fat metabolism.

While the Academy of Nutrition and Dietetics says any increase is likely to be small, green tea may help manage weight and health in other ways. The National Center for Complementary and Integrative Health says it is safe to consume up to 8 cups of green tea a day.

People should speak with a doctor before increasing their intake of green tea or consuming it during pregnancy. It may interact with some medications. During pregnancy, it may increase the risk of birth defects due to low folic acid levels. Does green tea help with weight loss?

The authors of a small study found that combining resistance training with dietary measures led to a slight increase in metabolic rate, but it was not statistically significant.

Participants who did only resistance training saw a reduction in fat mass and an increase in lean mass. Research suggests that when a person has more muscle mass, their body uses food for energy more effectively.

In other words, their metabolism is less wasteful. The researchers suggested that fat free mass lean mass and thyroid hormone levels might help account for the variability.

Resistance training may involve lifting weights and doing exercises that use the weight of the body or resistance bands to build muscle.

A previous study , from , found that high intensity interval resistance training also increased metabolic rate. Interval training is highly intensive and may be more suitable for people who are already fit than those who are new to regular exercise.

How can exercise help you build muscle? Staying hydrated is essential for the body to function at its best. Water is necessary for optimal metabolism, and it may help a person lose weight. In , scientists assessed the metabolic rate of 13 people who consumed either or milliliters ml of water.

They found evidence of increased fat oxidation after ml when a person is at rest, and concluded that drinking water may have an impact on metabolism. However, they did not find that it increased metabolic rate. This may happen because the additional water helps the body burn fat preferentially over carbohydrate.

How much water should I drink each day? Stress affects hormone levels, and it can cause the body to produce more cortisol than usual. Adrenal glands produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions.

Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate ATP , which is used to fuel various other cellular processes. Basically, mitochondria help turn the energy we take from food into energy that cells can use.

Exercise increases the number of mitochondria improving our body's ability to produce energy. Two excellent ways to supply energy to the mitochondria are L-carnitine and creatine from natural food sources.

Not only do they help provide energy to the body, but they are integral in helping build muscle mass. One can get plenty of both through animal protein like grass-fed beef, bison, eggs, and poultry; however, plant-based proteins like beans, nuts, and seeds can also do the job.

If you are trying to boost your energy, B vitamins are a great place to start. B vitamins are water soluble and therefore your body absorbs only as much as it needs, and any excess passes through your urine.

Vitamin B12 plays an important role in energy production as it helps transform the food we eat into energy that cells can use, helps form red blood cells that are necessary for lung function, and converts fat and protein to energy.
