"Coffee, when consumed in moderation and without too many added sweeteners can help you lose weight and be good for overall health," said Ashley Shaw, nutritionist at Preg Appetit.

 Coffee contains nutrients such as niacin, potassium, magnesium, and antioxidants, which can improve digestive health, support muscle function, and lead to better heart health. It also contains caffeine that boosts energy, reduces insulin sensitivity, and promotes weight loss.

 Here are some health and weight loss benefits for this energy-boosting drink:

 - Black coffee is a low-calorie drink: Weight loss is associated with a lack of calories, which occurs when you consume fewer calories than you burn. One common way to help achieve a calorie deficit is to consume fewer calories than usual calories.

 Black coffee is an ideal drink for weight loss, with less than 5 calories per serving (1 cup). However, they are low in calories only if you drink them black.

 - Caffeine boosts metabolism: Metabolism is the process in which the body disassembles nutrients and uses calories for foods throughout the day.

 Caffeine, a stimulant found in coffee, is one of the few substances that may increase the primary metabolic rate (BMR), also known as the rate at which calories burn during rest. 

 A small study conducted in 2018 found that participants who drank different measures of coffee over a two-month period had greater metabolic outcomes, the product of metabolism. A higher or faster metabolism will allow you to burn more calories during rest or physical activity, which can help with weight loss.

 Caffeine may reduce hunger. Appetite is affected by a variety of factors, including the type of food you eat, levels of physical activity, and hormones. Although there is not enough research to determine the cause-and-effect relationship to reduce caffeine appetite, studies have shown that it may reduce levels of ghrelin, a hormone that makes you feel hungry.

 A small 2014 study found that participants increased their sense of fullness and reduced their eating within just four weeks of drinking coffee daily based on ghrelin levels.

 How to drink coffee to lose weight:

 

For the health benefits of coffee and weight loss, Shaw recommends eating no more than four cups of coffee a day, equivalent to 400 mg of caffeine. 

 "Four cups of coffee a day offer the benefits of feeling more alert and improving fat metabolism and there is little impact on sleep and hunger," says Shaw. Drinking a cup every two hours would be good for feeling the lasting effects of each period. 

 However, if you like strong coffee, drink fewer cups accordingly so you don't get more than 400 mg of caffeine a day, according to Russia Today.

 She added that black coffee is best for weight loss because it does not contain sugars or added fats that can contribute to weight gain. 

 If you're new to black coffee, it may be helpful to gradually reduce the sweetener until you get used to the bitter taste. If you have a sensitive stomach, it's best to eat alongside your coffee because this acidic drink can cause stomach disorders, shaw says. She noted that too much pressure on the digestive tract can cause weight gain.
