“Can obesity be fixed without medications?”

Yes

Absolutely, it can. Eating a healthy and balanced diet and limiting your intake of things like sodas, fried and fatty foods, and sugary desserts will help, as well as getting some safe exercise that your doctor approves of. Many people successfully lose weight with the help of a nutritionist and their doctor. Be sure to get plenty of sleep and drink enough water during the process.
