Don't overeat, but don't be too thin. Eating too much will accumulate fat. If you eat too little, your body will tend to break down muscles, reduce metabolism and store energy in fat first. Ensure the balance of calories, eat carbohydrates: fats: protein in a balanced ratio of 60:25: 15, eat less and eat more meals, so that your blood sugar will be in a relatively stable state, your body will be more comfortable, and you should absorb as much as you metabolize. Don't hoard fat. Simple aerobic exercise can last for a long time and consume more calories, which can play a good role in the initial stage of weight loss, but the body will gradually adapt to this challenge, which will also aggravate the trend of decreased metabolism and fat accumulation. Therefore, after you meet the platform period, you should add some strength training to increase the proportion of muscles and ensure vigorous metabolism. You don't have to go to the gym to do strength training, but you can also do self-weight training. But first of all, I suggest you find a professional to guide you, and don't hurt yourself because of incorrect posture.
