2. Add tomatoes to your meal
An effective way to fool your brain is by eating tomatoes, whether in salads, sandwiches, or just by themselves. Research indicates they're rich in compounds that control the levels of appetite-regulating hormones, including lowering the level of the hormone ghrelin, making us feel full.
A study involving a small group of women aged 18 to 35 bore out tomatoes' ability to fill us up. The women were given cream cheese sandwiches made either of white bread, bread enriched with carrots, or bread enriched with tomatoes. According to the Daily Mail, the researchers thought the carrot bread would be the most filling, but were surprised when tomato bread turned out to be the most satisfying. Lycopene, the pigment that makes tomatoes red, may be responsible for taking the edge off the appetite; it's already credited with numerous other health benefits, from boosting fertility to defending against cancer.
