Does coffee really help you lose weight

 Evidence remains unclear about whether coffee plays a role in weight loss in obese people. The results of much of the related research are inconsistent, but some indicate that drinking coffee does not contribute to weight loss, [1] for example; Some studies have noted an effect of coffee on weight loss, including a review published in the journal Critical Reviews in Food Science and Nutrition in 2018, which indicated that consuming 2 milligrams of caffeine per day had an effect in reducing obesity problems. This led to lower weight, lower body mass index, and lower body fat, compared to those who consumed 1 milligram of caffeine per day.

The results of research and studies on the effect of caffeine on appetite differed greatly, as some theories indicated that caffeine affects weight by suppressing appetite, reducing the feeling of hunger and the desire to eat for a short time, and the second theory is the burning of calories. It states that caffeine can increase the body's energy consumption when it is at rest, in addition to that it stimulates the body to produce energy and heat accompanying the digestion of food.

On the other hand, the results of other studies on the effect of caffeine on appetite differed, as some showed that consuming caffeinated drinks throughout the day may lead to weight gain. Because caffeine can raise levels of the stress hormone in the body known as cortisol. Which increases the body's ability to store energy, raises the heart rate and blood pressure, and in addition to that, drinking caffeine can lead to a decrease in blood sugar, and thus it increases a person's desire to eat high-calorie foods; That is, the more caffeine is consumed, the more the body needs to eat foods that produce glucose. Such as: starches, sweets, fruits, and milk. 

In general, there is no single cause of obesity, and there is no single solution to it, and consuming one type of food or drink cannot be sufficient for healthy weight loss [5], as the best way to lose weight in a healthy way is to reduce the number of Calories intake and increased level of physical activity; This is done by reducing the consumption of foods high in calories; Including: sugars, juices, in addition to artificial sweeteners and cream, which would help increase the rate of energy burning compared to the rate of energy consumed from food and drink.
