Avoid These Foods for a Reason

The list of foods that lower levels or inhibit the actions of the appetite-regulating hormone leptin includes many of the foods you should avoid for other reasons. Foods high in saturated or trans fats may block leptin from reaching the brain. Alcohol is no friend to your leptin levels, and animal research suggests that high-fructose corn syrup causes leptin resistance. Steer clear of these foods! Also, eating a huge dinner can delay leptin release, so you want to be sure to spread your calories evenly throughout the day.
