First, researchers interviewed thousands of people about weight loss.
Through thousands of focused surveys, interviews and discussion, the main problems people
had in previous weight loss attempts were:
1. Weight loss is too slow. It’s so slow, you get frustrated and give up.
2. It’s confusing. How much to eat? What foods to eat?
3. It's too hard to control portions.
4. Eating habits are too strong.
5. Feeling hungry all the time.
