Athletes who tend to overeat while following a high-carbohydrate diet should consider avoiding wheat as a strategy for controlling appetite. Wheat contains opioid peptides that mimic the effect of opiate drugs in the brain. Opioid peptides have an analgesic or sedative effect, which can enhance appetite in those who unconsciously wish to replicate this effect through diet. It’s not surprising to find that dairy products also contain opioid peptides. Many so-called “comfort foods,” such as pizza or macaroni and cheese, are accurately named because they contain both wheat and dairy products. Athletes who struggle with appetite control while eating a high-carbohydrate diet will likely benefit from substituting fruit, potatoes, sweet potatoes, or squash for wheat in the diet.
