Calorie calculation method:
1. People should know how many calories they should consume every day and how many calories their bodies need. It depends on many factors, such as how quickly you want to finish your weight loss plan or how many calories you consume in physical activity. Under normal circumstances, women should consume no less than 12 calories a day.
2. Have your own diet plan and carry it out perfectly. Of course, you can adjust it at any time, but if it is not necessary, it is best to keep the basic plan. There are at least three meals and two snacks in the plan. Feeling deprived of food will make it more difficult to lose weight. Make sure you get enough energy in each food group, especially fat and protein, which will help you feel full.
