Caffeine doesn't take effect until it is drunk for an hour, so drinking it in time before the meeting and before studying will refresh your mind and improve the efficiency of work and study.

2. Improve the effect of exercise to lose weight

Drinking coffee before exercise can stimulate sympathetic nerve, decompose visceral fat and promote blood circulation.

The combination of coffee and exercise can effectively burn visceral fat and achieve the effect of losing weight. If you want to get better fat burning effect, it is recommended to drink black coffee without sugar.

3. It can reduce body fat.

Coffee contains chlorogenic acid, which can promote lipid consumption and reduce body fat.

However, in order to exaggerate the efficacy of coffee, many merchants will mark the words burning fat on coffee drinks. Don't choose blindly. It is recommended to refer to the ingredient list more. Only black coffee without additives can achieve the expected effect.

Three disadvantages of drinking coffee

1. May suffer from insomnia.

It is best not to drink coffee within 4 hours before going to bed. Drinking coffee before going to bed will affect sleep and make it shallow. In addition, the diuretic effect of caffeine is likely to increase the frequency of going to the toilet at night, which may hinder sleep.

2. Obstruct the absorption of calcium

Coffee will increase the amount of calcium excreted by the body. People who like to drink coffee every day and don't supplement calcium much may have osteoporosis. Therefore, people who usually like to drink coffee must pay attention to calcium supplementation.

Not only coffee, but also energy drinks, cola and green tea all contain caffeine. Also control intake and pay attention to calcium supplementation!

3. Hinder the absorption of iron

Like calcium, a "tannin" of polyphenols in coffee will hinder the absorption of iron. So don't eat iron-rich food with coffee. It is recommended to drink some water or wheat tea with meals and coffee at rest.

After understanding the advantages and disadvantages of coffee, drink coffee reasonably and become healthy and thin!
