It is true. Some foods have such a high thermogenic effect to literally burn calories as you chew. So you do not have to do anything else but to feed your metabolism with them.
1. Whole grain Cereals
Your body burns twice as many calories doing full split of whole grain foods (especially those rich in fiber, like oatmeal and brown rice) than processed foods.
2. Lean meat
The protein has a high calorific action. It can burn approximately 30% of the calories it contains and is a food rich in proteins during digestion. So a chicken breast at 300 calories consumes about 90 calories to break.
3. Dairy products with low fat
Dairy products are rich in calcium and vitamin D while also contributing to maintaining and building muscle mass which is essential for maintaining a robust metabolism.
4. Green tea
Drinking four cups of green tea a day has proven that you can lose more than six pounds in eight weeks. It contains EGCG and catechins that speed up your metabolism temporarily. So do not forget to always have a pitcher of iced tea in the fridge.
One cup of lentils contains 35% of the daily needs of the body iron. At the same time, 20% of people have iron deficiency at some point in their lives. But when there is a lack of a nutrient in your body, your metabolism slows down because the body takes what it needs to operate effectively. So, the lentil is a good legume to fill in the gaps of ironas well as spinach.
6. Hot peppers
Capsaicin is the substance that gives the peppers their pungent flavor and warms your body thus burning more calories. The peppers can be eaten raw, cooked, dried or powdered. Also add as much as possible hot red pepper sauce in soups, meat and eggs.
