this thread is started by request. the paleo diet, essentially, consists of eating only lean meats, fruits, vegetables, and nuts. all dairy, grains, cereals, processed foods, sugar, and starch are eliminated. the most controversial group eliminated in my experience would have to be dairy. many people still include dairy if they simply cannot let it go....the main problem with dairy is the high saturated fat content, which can be avoided by buying non-fat milk. milk is still slightly high in sugar however. the diet works, basically, just because your eating clean as all hell. i doubt there is any cleaner way to be eating. you eat absolutely zero refined carbs and sugars which can cause blood insulin to spike, and replace them with fruit and vegetables, in which the carbohydrates cause slow gradual rises in blood sugar and are therefore not damaging. ever meal includes some kind of lean meat, including lobster, shellfish, tuna,turkey, chicken breast, organ meats and various different kinds of wild game. meats you need to eliminate are the horribly fatty ones like hot dogs, pork chops, ham etc. fats come from the meat,nuts, and various different kinds of oils such as flaxseed,canola, and olive, all bad fats are eliminated.... all vegetables are allowed with the exceptions of potatoes, which are very starchy and can cause blood sugar levels to spike. so far ive been eating this way for awhile. i try different diets, such as the warrior diet, and manipulate macronutrient breakdowns and such, but the food choices never really change.
