Weight loss seems to be a topic that people are always passionate about. Drinking black coffee is also the choice of many people who lose weight. So, can black coffee really help lose weight?
First of all, coffee still has a certain health value. Because it is rich in caffeine and polyphenol antioxidants, which have many health benefits, including reducing inflammation and free radical damage.
As for weight loss, coffee seems to have two potential benefits: promote metabolism and reduce appetite. It is mainly caffeine that can promote metabolism. A number of studies have confirmed that caffeine can increase a person’s metabolism, allowing the body to consume more energy at the same time.
In a survey involving more than 600 people, researchers found that more caffeine intake was associated with a decrease in body weight, body mass index (BMI) and fat mass. When the participants doubled their caffeine intake, their weight, BMI and fat mass dropped by 17%-28%.
Coffee enables exercise to burn more fat. A study observed the effect of 7 healthy men drinking about 1 cup (250 ml) of water or caffeinated coffee after 30 minutes of exercise. It turned out that those who drunk coffee burned more fat than those who drunk water.
However, these studies are still not enough to confirm that coffee has an exact weight loss effect.
Regarding the reduction of appetite, studies have shown that drinking coffee before meals will reduce meal intake. However, if the coffee is too long away from the main meal, for example, if you drink coffee three or four hours before the meal, the food intake for the next meal will not be affected.
A study of 33 overweight and normal weight people found that coffee could reduce the calorie intake of overweight people. But in another study, coffee did not show such a good effect. Therefore, whether coffee can help reduce calorie intake requires more research.
Some of the weight loss coffees sold online are just black coffee or instant black coffee with some publicity from the sellers. Some others may be added something helpful to weight loss, such as “L-carnitine.” Like caffeine, whether L-carnitine can actually help weight loss is not entirely certain. Therefore, while buying “weight loss coffee”, you should pay attention to whether the coffee is just black coffee or something with other additions. And if other ingredients are added, you must figure out whether the manufacturer is formal and whether the product has a formal batch number, etc.
Therefore, the effect of coffee on weight control is only a small part. As for whether coffee is good for your health, it is mainly a question of quantity. As long as you drink the right amount, it is good for your health while excessive drinking may be harmful.
For healthy adults, it is safe to consume coffee with no more than 400 mg of caffeine per day. Pregnant women should not consume more than 200 mg per day.
Another thing to note is that when we discuss the health issues of coffee, we are talking about black coffee, which refers to coffee without sugar or cream. After adding dairy products and sugar, coffee or milk tea will not only explode in calories to make you fat, but also make your suffer from oily skin and acnes.
