I've recently lost a lot of weight and am having a hard time getting it back on.

I'm sorry to hear that! You can try eating more healthy foods, like fruits and vegetables, lean proteins, whole grains, and low-fat dairy products. Also, make sure to stay hydrated by drinking plenty of water throughout the day. Additionally, you could consider exercising regularly, even if just for short periods of time. This will help you increase your energy levels, as well as burn calories.
