Weight gain usually happens over time. Most people know when they've gained weight. Some of the signs of overweight or obesity include:
- Clothes feeling tight and needing a larger size.
- The scale showing that you've gained weight.
- Having extra fat around the waist.
- A higher than normal body mass index and waist circumference. (For more information, go to "How Are Overweight and Obesity Diagnosed?")
