Eat less yet be full
- Eat disgusting food: Eat the most utterly disgusting food you can find. Can you? Na. I can't. What I do is to keep the salt a little less than normal so that the food would taste simple and bland making me eat lesser food. It would be wise to use less salt. Salt sometimes makes you crave more food and water.

- Eat your veggies first: Annoy your appetite away with high fiber foods first. Eating your veggies first would kick start food processing in the stomach making you eat less. Eating veggies have many other advantages including essential vitamins, lowers the risk of certain cancers, heart disease and other chronic diseases and conditions. Hate eating vegetables? Who is the strongest cartoon superhero?
- Eat slowly: Worse come to worse, your stomach only has a 30 minute hunger cycle. Even if you are starving, in 30 minutes, you'll lose your appetite and stop eating. I see this happen with most people, especially when you have lunch with friends or colleagues or when you are in a hurry. You forget what your teeth are designed for - Chewing! Chew your food long enough to make it easy for your stomach to digest it. Also chewing your food helps you enjoy what you are eating and saves you from constipation.
