Yes, even if you are overweight, you should gain weight, but not more than twenty-five pounds. For overweight women, it might range between fifteen and twenty-five pounds. However, if you are fat, your doctor may advise you to lose weight. This should only be done if your doctor instructs you to. Otherwise, you might hurt yourself by losing too much weight too fast. If you are underweight, you should try to eat more meals and snacks and reduce the amount of time you spend watching television or eating at restaurants. Additionally, if you are underweight, your muscles will begin to waste away if they are not used regularly, so make sure to keep active by going for walks or doing other things that increase your heart rate. You should also consider joining a sports team or taking up dancing - these activities will help you build muscle mass as well as give you something to focus on other than eating junk food all the time. Finally, if you are underweight, your body needs more calories than it is getting, so you should try to eat more foods with protein and fiber in them (such as beans, peas, whole grains, and vegetables) and less sugar and processed foods. In conclusion, yes, a woman can gain weight if she is overweight. It is important for you to know your own body and what kinds of changes you can afford to make before deciding how to move forward with your health plan.
