Drinking coffee like this is effective
The claim that coffee has a weight loss effect is not groundless. Coffee contains caffeine, which is the main effective ingredient of coffee. Caffeine has two effects related to weight loss.
1. Caffeine has a diuretic effect. Studies have long shown that caffeine has a diuretic effect. Since it is a diuretic, it can naturally eliminate the water in the body, and of course, the weight will be reduced.
2. Caffeine has an exciting effect and can increase the basal metabolic rate. This is also true. Now that the basal metabolic rate has increased, weight loss is a matter of course.
But don't be happy too early. In fact, most people who drink coffee to lose weight are still getting fat as before, and even getting fatter! What about drinking coffee to losing weight?
Emphasize one point, that is, you can't talk about the role without data and dose, otherwise you will be a hooligan. Let's analyze it.
Let me talk about the diuretic effect of caffeine. Know that diuresis can never lose weight! You know, diuresis excretes water, not fat. Although the weight is lost, there is no less fat. Just drink some water or eat more salty food, and the weight will return immediately. Besides, the diuretic effect of caffeine is very weak, I think it can be ignored.
Let's talk about the effect of caffeine on improving basal metabolism. Caffeine does excite the central nervous system, speed up the heartbeat, and increase basal metabolism. But (usually but the latter is the focus), the effect of improving the basal metabolism of caffeine is very small. Drinking a cup of coffee with 200 mg of caffeine can only increase it by about 1 to 3%. Taking a girl with a basal metabolism of 1,000 calories as an example, an increase of 3% only increases the energy consumption of 30 calories. Compared with more than 1,000 calories a day, 30 calories can be completely ignored.
This is why most people who drink coffee to lose weight do not get results. So what happened to those who get fatter the more coffee they drink? It turns out they drank the wrong coffee.
The calories of coffee itself are very, very low. A cup of pure black coffee has less than 5 calories. You can think that pure coffee has no calories.
However, apart from pure black coffee, most coffee is not pure. For example, adding milk or milk froth for a latte is not a big problem, but many people feel bitter and add a lot of sugar. Again, additional sugar is a taboo for weight loss. Free sugar is rapidly absorbed to raise blood sugar, and blood sugar that cannot be consumed is converted into fat in a short time. High blood sugar repeatedly stimulates insulin secretion, which will eventually aggravate insulin resistance, making the tissues less able to use blood sugar, making it easier to gain weight. In addition to milk, some coffees have to be creamed, such as mocha. The heat is higher.
But these coffees are not the most likely to cause weight gain. The most likely cause of weight gain is 3-in-1 instant coffee. This kind of convenient coffee actually contains very little coffee, mostly sugar and non-dairy creamer. For example, a certain classic original three-in-one instant coffee has 80% carbohydrates and 13% fat! What concept? Just eat candy. If you drink this kind of coffee every day, you still have to drink a few cups a day, it won't make sense to not get fat.
It seems that drinking coffee to losing weight is really unreliable. Wait a minute, coffee can really lose weight, the key is to drink the right coffee.
A. First of all, don't give the weight of weight loss to coffee. Coffee can only assist with weight loss. The key to weight loss is to control your mouth and open your legs.
B. The timing of drinking coffee is very important. Drink it before exercising. Coffee has a stimulating effect, which can make you unconsciously increase the amount of exercise when you exercise, without feeling tired. Simply put, drinking coffee before exercise can increase exercise volume, thereby increasing calorie consumption.
C. Drink pure black coffee, that is real coffee. And you can completely ignore the little heat of the coffee. If you are really not used to black coffee, add some milk, but no cream or sugar.
D. If you want to drink convenient instant coffee, please choose pure coffee powder, which is a bit expensive.
what? Unsweetened coffee is too bitter? Why do you want coffee?
