The obesity epidemic demonstrates that people are having difficulties with managing their energy intake and energy expenditure. Strategies to make controlling energy intake easier and more enjoyable are therefore needed. The results of this thesis suggest that lowering eating rate, i.e. the amount of food consumed per unit of time (g/min), could be an effective strategy as it can make people feel full on fewer calories. Several strategies for lowering eating rate and their potential to lower energy intake and body weight were explored. The strategies that showed most potential were: 1) lowering a person’s habitual eating rate, for example with the help of a device that tells you to take more time in between bites, and 2) choosing foods that take more time to consume, for example by avoiding caloric beverages as they can be consumed very quickly. Further research is needed to confirm whether these strategies are effective in reducing long-term energy intake and managing body weight. Lowering eating rate is expected to not only make portion control easier, but also to make eating more enjoyable.
