No one can give you the answer. What matters is how long you want the answer, and you have to pay twice as much sweat for this time (this is real sweat). I can only tell you that it is difficult for you to lose 40 pounds. I lose 60J a year, but my ratio is big, so I lose quickly, and yours is much smaller, so it will take at least one year. Besides, I didn't mean to scare you. I want to lose weight. Losing weight is a healthy exercise. If you lose weight, your sweat will be put in a bowl every day, not just dried with a towel. You have to think about whether you have the perseverance and determination. Otherwise, you don't need to reduce it, because you can't stand the rebound speed. My rebound has reached 5-6J every day after three days, and it will be 15- 16J after three days. Please think it over first. In addition, weight loss requires methods, including a reasonable diet and proper exercise every day (the more exercise, the better, the less diet). You need to try to adjust according to your state. For example, you must go on a diet to lose weight, but no one knows how hungry you are to avoid overeating, so you should control the amount yourself. Customize your own weight loss plan according to your own situation. Remember, the most important thing about the weight loss plan is not how tough and perfect it is, but whether you carry it out perfectly according to the plan. The plan can be adjusted at any time, but the effect of completion is that you waste a day. Control yourself.

In addition, talk about the necessary knowledge of slimming, aerobic exercise to reduce fat, anaerobic exercise to gain muscle, aerobic exercise to lose weight, anaerobic exercise to eat meat, aerobic slimming, anaerobic exercise to exercise bones and muscles, these must be combined, otherwise losing weight will make you inhuman. For example, the belly is like orange peel, the legs are like elephants and so on. Once this happens, it is more difficult to change back than to lose weight. Pay more attention to it. Learning fitness knowledge will help you lose weight successfully. If you sharpen your knife, you won't miss the woodcutter, otherwise you will get twice the result with half the effort.

Finally, I wish you an early success.
