Why does drinking black coffee make you gain weight?

In modern society, many people like to drink coffee to refresh themselves. For those who want to lose weight or maintain their figure, they may choose to drink black coffee, because compared with other types of coffee, black coffee does not contain sugar and dairy products, so it has lower calories. However, some studies have shown that long-term and large-scale drinking of black coffee may lead to weight gain. So why does drinking black coffee make you gain weight? The following will analyze it from several aspects.

1. Stimulate appetite

First, before discussing why drinking black coffee can cause weight gain, we need to understand the hormone insulin. Insulin is one of the hormones secreted by the pancreas and plays a key role in regulating blood sugar levels. When we consume food, especially foods containing carbohydrates, blood sugar levels rise and stimulate pancreatic islet cells to release insulin to lower blood sugar.

However, caffeine interferes with the normal secretion of insulin. Studies have shown that consuming large amounts of caffeine can cause pancreatic cells to respond less effectively to blood sugar, thereby increasing appetite. This means that when we drink black coffee, we may feel hungrier and tend to consume more food and energy.

2. Affects metabolism

Secondly, drinking black coffee may also affect our metabolic process. A study found that when drinking a lot of coffee for a long time, the fat oxidation (ie fat breakdown) process in the human body is inhibited. This means that the body cannot effectively convert fat into energy and is more likely to store it.

In addition, drinking black coffee may cause hormonal imbalance in some people. Hormones play an important role in regulating metabolism, appetite, and weight. If hormones are out of balance, this may lead to weight gain.

3. Drink selection

In addition to the above two aspects, when discussing why drinking black coffee will make you gain weight, we also need to consider the issue of beverage selection. Although black coffee itself has low calories, if we add sugar, creamer or other high-calorie ingredients when drinking coffee, the energy intake will be greatly increased.

In addition, some people may habitually pair black coffee with high-sugar, high-fat foods, which not only consumes extra energy, but may also lead to blood sugar fluctuations and abnormal insulin secretion.

in conclusion

To sum up, when discussing why drinking black coffee will make you gain weight, we can draw the following conclusions: First, caffeine interferes with insulin secretion and increases appetite; second, long-term and excessive drinking of coffee may inhibit the fat oxidation process and lead to hormonal imbalance; finally, when choosing beverages and pairing foods, you also need to pay attention to avoid extra intake of high-energy foods.

Therefore, in the pursuit of healthy weight loss or maintaining a healthy figure, it is not recommended to drink a lot of black coffee for a long time. If you really like to drink coffee, you can drink it in moderation and try to choose low-sugar and low-fat ingredients.
