All diets work when you want to lose weight. I've seen Asians on all rice diets (all carbs) and get all skinny and no diabetes. I've seen guys on McDonald's diets eating only a lean chicken breast sandwiches. Key is to eat LESS calories than your body burns to lose weight. But not all foods are healthy and are prone to increasing the chance of cancers hence my point of mentioning the GMO engineered junk food Hawaiians are known to devour and consider a fine delicacy all thanks to the Jones Act that keeps healthy fruits, veggies and seafood and lean meats prohibitively expensive and out of reach for many to eat healthier.
