The Shangri-La Diet is based on the premise that the body wants to find a set weight, depending on what the dieter is eating, and not stray from that weight. Thus, if an individual eats tasty food, the brain will want more, causing weight gain. If an individual eats bland food, the brain desires less and allows weight loss. The idea is to eat whatever food is desired while staying away from processed foods or items with high-fructose corn syrup. The actual diet involves eating a couple meals each day and drinking a few tablespoons of liquid in between meals. Over time, the individual's food preferences may change, and they can lose weight by desiring to eat less food. Although some individuals may lose weight on this diet, they might not stick to it long term, as it restricts many tasty foods which may not actually cause weight gain.
