Pepper weight loss tips

Pepper, the reason that people can't refuse is: burning fat and cultivating oneself!

Capsaicin is the key to burning fat in pepper. As long as you eat one or two spoonfuls, the stimulating taste will immediately send a signal to the brain that "enough is enough", resulting in a great loss of appetite. At the same time, another important function of capsaicin is to stimulate the body's heat-producing system and accelerate metabolism. A fast heat-generating system can improve the working efficiency of the body, just as a fast-running machine consumes a lot of hydrocarbon fuel.

After eating a spicy meal, you can consume more than 25% calories. When spicy food is burning in the stomach, it is more obvious to drink a cup of caffeine-rich black tea. Pepper can also promote the production of two enzymes in the body. In the process of burning fat, they can "persuade" fat cells to unload, while preventing excessive accumulation of fat. This method of losing weight does not need any dietary rules, because capsaicin stimulates the production of endorphins and serotonin, which will also make you feel good.

In the daily diet, what should I do if I want to eat without worrying about my health? The first course needs to be spicy, which is to burn calories better next. If you want to control your appetite, you must remember that protein's rich food is easy to increase your appetite, so put more onions and shallots in your dishes. Don't use packaged spices, because they are all substitutes for capsaicin and don't work. Finally, the spicy food is ready, and if it is kept for 2 hours, the capsaicin will automatically heat up.

But what if someone is afraid of eating spicy food? Spicy is caused by capsaicin, which stimulates the pain of nerve endings. There is a good way to make your mouth not afraid of spicy food: eat Chili regularly, let it adapt little by little, and the pain in your brain will gradually numb.

Beginners who eat spicy food are advised to take a sip every day for lunch and dinner at first, and then drink some milk or yogurt, because protein in milk can relieve the taste stimulation and stomach acid caused by capsaicin. In addition, you can gradually adapt to the spicy taste of spices containing Chili powder, and then gradually expand your tolerance for Chili. It is ideal to eat green pepper, which is rich in vitamins and relatively less capsaicin. Green pepper tastes good and can avoid stomach acid.

While eating spicy food, you must eat breakfast: wake up the metabolic system in the body to prevent hunger from invading later; Choosing low-fat milk can make you feel full immediately; Don't eat cream cake often in the morning. On the contrary, we can eat some Chili slices. Eat fruit four times a day to supplement vitamins and rich fiber. There are two kinds of people who should be careful when eating Chili.

Pepper is a tonic for women.

Pepper is spicy and stimulating, which has a good effect on stimulating appetite. However, many women think that eating Chili peppers is easy to get angry, which leads to "small acne" on their faces.

Because pepper not only has bactericidal effect, but also contains a substance called capsaicin, which can promote hormone secretion, thus accelerating metabolism to achieve the effect of burning body fat, thus playing a role in losing weight. And the ingredients of pepper are natural and reliable. In some areas dominated by spicy food, local women not only have less acne problems, but also have slippery skin.

People with cold foundation deficiency and cold have slow blood circulation, and often have symptoms such as cold hands and feet, weakness of limbs, low blood pressure and dizziness. Therefore, eating more spicy and warm food can promote blood circulation and help alleviate the symptoms of deficiency and cold.

On the other hand, pregnant women should not eat spicy food often because of heat, yin deficiency, damp heat and sweating, or they will be heated, which will aggravate the discomfort of hot air, dry mouth, redness and fever, and the consequences may be more serious.

Even people with cold buttocks should eat properly according to their physical condition, because eating too much will produce hot air at any time and sweat too much, which will lead to water loss, sore throat and swollen teeth, but it will be counterproductive. So it is ok to eat spicy hot pot once or twice occasionally, add two drops of spicy oil and use pepper as seasoning, but not every day.
