Drink black coffee before exercise

Black coffee is a very healthy drink. A 100-gram cup of black coffee contains only 2.55 kcal. So drinking a cup of black coffee after a meal can effectively break down fat. Black coffee has a stronger diuretic effect. Black coffee can also promote cardiovascular circulation.

For women, black coffee also has a beauty-enhancing effect. Drinking it regularly can make you radiant and beautiful. Patients with low blood pressure can make themselves in better condition by drinking a cup of black coffee every day. Drinking black coffee before exercise is a controversial topic among many people. Let’s find out whether it is okay to drink black coffee before exercise.

Coffee contains caffeine, which promotes fat decomposition and inhibits fat synthesis. So drinking coffee can also help you lose weight.

However, many people are not very clear about the health effects of caffeine, except for its excitement and refreshing effect.

Caffeine itself does not affect the absorption of nutrients, but it has a strong diuretic effect, promoting the excretion of nutrients that have been absorbed in the body with urine. That is to say, after drinking coffee, the amount of urine will increase significantly, and the kidneys cannot fully absorb the nutrients in the original urine into the blood as usual. As a result, many important nutrients such as potassium, magnesium, and B vitamins will be lost as they "leak" out of the body with urine.

At the same time, caffeine can effectively promote urinary calcium excretion, which may disrupt the body's calcium balance. If the normal calcium intake is insufficient, or if the diet does not contain enough vegetables, beans, seaweed and other foods, the acid-base balance tends to be acidic. Then, under the effect of caffeine, the body's mobilization of bone calcium will be aggravated, which will lead to osteoporosis over time. For women over 35 whose bone density begins to decrease, especially those in menopause, the impact cannot be ignored.

In addition, people who are prone to cramps and edema, as well as women with dull skin, dark circles under the eyes, and excessive oil secretion should also strictly control their coffee consumption, because the loss of minerals and vitamins will aggravate these symptoms.

Because everyone's physique is different, the amount and time of consumption of black coffee should vary from person to person. People with a fast heart rate are not suitable for drinking coffee before exercise. If you do this for the purpose of losing weight, it is not a good method. The key to losing weight is to eat less and exercise more, and don't drink coffee blindly.
