Two cucumbers will do. The best way to lose weight is to give priority to exercise, supplemented by dieting. Of course, you should control your food intake, but I think two cucumbers should not be a problem that bothers you to lose weight. Try to do some simple aerobic exercise, such as running at home (this is the method I introduced in a successful example of losing weight in CCTV). In short, try to stick to simple exercise! Although things are small, persistence is the most important thing. With determination, you can achieve satisfactory results.
