Participants were obese men aged 40 years or older who had an average body mass index (BMI) of 27 and were equally divided into two groups. The researchers asked the two groups of participants to eat muffins and orange juice for breakfast (which contained 85 grams of carbohydrates, 25 grams of fat, 7 grams of protein, and 595 calories). The difference is that one group has a cup of hot water for breakfast, while the other group has 2 grams of ginger. Six hours later, the researchers measured the calorie expenditure of the participants. The results showed that ginger could enhance the feeling of fullness after a meal, and the group containing ginger consumed a total of 43 kcal of calories. If you eat it daily, this effect may be even greater. If you can add some ginger to your diet every day, you will lose 2 kilograms of weight a year.
