First of all, it depends on whether you want to lose weight quickly or whether you plan to do it as a matter of life. If you want to lose weight quickly, your plan is feasible, but I suggest you add exercise, such as climbing stairs and skipping rope, which has a good effect. You should stick to it! If you are not too fat and have a normal weight, but have a high demand on your body, you can take losing weight as a daily activity in your life. You can eat every meal, you must eat a good breakfast, and it doesn't matter if you eat something high in calories occasionally, but you must eat breakfast, lunch is normal, and dinner must be light and low in calories. Another important issue is that no matter what your situation is, you must pay attention to detoxification and defecation in your body. I wish you reach your ideal weight as soon as possible!
