One very easy strategy that can be used is altering the order that you eat things each meal. By drinking a glass or two of water, you are already filling up your stomach, meaning that hormones that lead to fullness will start being produced, leading you to feeling fuller sooner, and driving the hunger away.
1) By starting with vegetables/fruit, you are pumping your stomach with food that is low in calories (most vegetables are like 80% water, and water doesn’t typically have any caloric value). Following these low-calorie fillers, you can move on to protein sources.
2) Protein is a little harder to digest than fats or carbohydrates, and they’re much less likely to be stored as fat (the process of turning protein into fats – gluconeogenesis/ de novo lipogenesis – is not a major factor in fat gain). Protein has been proven to make people feel fuller for longer than carbohydrates, and they have a much lower caloric density than fats. A
3) After pumping your stomach with bulky vegetables, nutritious protein, you can move on to the fun things – carbohydrates and fats. By this point your belly should be pretty full, meaning that the potential for over eating fats and carbohydrates is reduced!
