Studies suggest that coffee may help people lose weight and help lower their risk of developing diabetes.

In one study in France, a group of volunteers was given a supplement of 400 mg of decaffeinated green coffee bean extract daily, while another group was given a placebo.

After a month, volunteers from the first group lost about 5.7% of their weight, while people from the second group lost only 2.8% of weight.

Although drastic weight loss was not achieved, the study demonstrated how gradual weight loss can happen after regularly taking coffee. Additionally, the study’s use of decaffeinated coffee showed that coffee’s fat-reducing effects may not be because of caffeine, which is known to burn calories.

Experts believe several chemicals in coffee called “chlorogenic acids” contribute to weight loss. These chlorogenic acids help digest food and slow down the production of fat and sugar in the body.

Because of the high amount of chlorogenic acids in espresso, experts say drinking espresso after meals may also be a good practice.

Meanwhile, studies in other countries suggest that regular consumption of coffee reduces the risk of developing diabetes. A study by Harvard University and two other different studies from the Netherlands all showed a direct connection between drinking coffee and the lowered risk of getting type-2 diabetes.

However, adding lots of sugar and cream to coffee does not help in losing weight or in preventing diabetes. To make the most out of coffee's health benefits, experts suggest taking black coffee, espresso, coffee with a small amount of milk, or green coffee bean supplements.
