According to this article sprinkling your food with chilli peppers can help to curb your appetite. Researchers from Purdue University in Indiana found that capsaicin in the peppers helps to reduce hunger and also increases energy expenditure burning more calories. It is more effective in those people who don’t regularly eat chillies. The study measured the effects of half a teaspoon of cayenne pepper and tested 26 people, 13 who, liked spicy food and 12 who did not. The study found that those who did not regularly eat chillies also experienced a decrease of hunger, especially for fatty, salty and sweet foods. It seems, however, that once people become familiar to the effect that it becomes less effective.
