Eating once won't be a big problem, but if you want to lose weight, you must ride a bike about four times a week. And dieting will make you slim down and get fat. Trust me, start eating beef, low fat. And you should increase anaerobic training, so as to maintain muscle mass. The higher the muscle mass, the higher your metabolism. For example, if you eat 1 0,200 calories a meal and your body needs to consume 1 0,300 calories, then you will be thin. Therefore, it is very important to improve metabolism, which is more important than dieting and car maintenance.
