Dr. William Davis developed the Wheat Belly diet. The diet focuses on eliminating wheat and managing carbohydrates. Davis explains the diet and why it works in his book "Wheat Belly: Lose the Wheat, Lose the Weight, and Find Your Path Back to Health."
In addition to eliminating all wheat, dieters also cannot eat foods made with barley, rye and other oats. The diet eliminates wheat because it raises blood sugar. Dieters also cannot eat gluten-free foods, as the ingredients in these cause the same effect.
Davis also recommends dieters eliminate several other foods, including high fructose corn syrup, salt, sugary foods and drinks, rice and potatoes. He recommends eating fruits that don't have high sugar content, such as berries, apples, vegetables and raw nuts; the diet also calls for grass-fed animal products, such as meat and eggs.
The plan recommends exercise, but it doesn't specify a type of exercise or frequency.
The Wheat Belly diet is an effective weight loss diet because of the unhealthy foods it eliminates. It works well for people who are sensitive to gluten, as it provides healthier alternatives to gluten-free foods. However, according to WebMD, scientific evidence doesn't support the theory that gluten causes more weight gain than other foods. The diet plan eliminates certain foods, such as legumes, that have many nutrients.
