"Coffee" is a highly controversial drink because caffeine can lead to addiction, and eating too much may cause palpitations, insomnia and other problems. However, Chiu Anzhong, a well-known Japanese dietitian, has used various data to confirm that, in fact, with three cups of coffee a day, there is no need to change any living habits, and you can lose 1.5 kilograms a year! Some studies have confirmed that drinking coffee before exercise is more efficient in fat burning and can lose 1.5 kilograms in 3 months.

As 30-40 minutes after drinking coffee, the concentration of fatty acids in the blood will become higher, when combined with the right amount of exercise, you can turn fatty acids into heat and burn fat effectively. For example, take a brisk walk for 10-15 minutes and take the stairs back to the office or home instead of taking the elevator; you can also do some small movements in place, such as twisting and stretching the upper body, tiptoeing, tucking in your abdomen, etc.

Although drinking coffee has the effect of losing weight, but drinking a lot of coffee for a long time, there are still some side effects. Here's an overview of some of the side effects of drinking coffee:

1. At present, there is no direct evidence that caffeine can lead to osteoporosis, and some studies have found that although caffeine increases calcium excretion, it is not a high risk factor for osteoporosis, and inadequate calcium intake is the main cause. Therefore, it is still recommended that attention should be paid to adequate calcium intake.

2. Avoid putting too much sugar: adding too much sugar when drinking coffee will reflexively stimulate the islet cells in the pancreas to secrete a large amount of insulin, while excessive insulin can reduce the content of glucose in the blood. Once the blood sugar is too low, there will be palpitations, dizziness, limb weakness, drowsiness and other hypoglycemic symptoms. In addition, when drinking coffee, it is not appropriate to eat too much cake, candy and other high-sugar food, otherwise it will also produce the above symptoms.

3. Although drinking too much coffee may hinder the development of the fetus, it has not been confirmed whether it will lead to preterm birth or low birth weight.

4. The more coffee you drank, the higher the increase of indexes such as reactive protein C, tissue necrosis factor and the number of white blood cells. The higher the risk of cardiovascular disease may be in the future. Drinking coffee in acute stage will slightly increase the effect of hypertension, but the effect is not obvious after long-term drinking.
