Black coffee is better for losing weight. But I suggest you: 1 Eat dinner instead of snacks every day. 2 the way to eat three meals a day is to eat early; Eat well in the afternoon; Eat late and eat less. 3 combine a small amount of exercise (excessive, etc.). ) I think it will make great progress if I persist for one month. Remember to drink plenty of water and don't let your skin lose its elasticity.
