I hate it when people quote paleolithic man, their diet and how good they looked. No, They didn't look good, their diet sucked, they are often hungry and there is hardly any variety in their diet. Sometimes, they could just be consuming a single one type of food for days or week and many died from malnutrition and lack of essential vitamins and minerals.
People trying to promote this should seriously stop this hypocrisy. They couldn't last one fucking day on a true paleo diet. Paleo men are lean because they are constantly in caloric deficit and physically more active. The modern "paleo" diet is nothing like what was consumed in those times. Today, followers of paleo diet get a good mix of protein, veggies, fruits, and healthy oils in their meals. Those days, they could be just dining on nuts or fruits if their hunt is unsuccessful. When they do hunt a beast, they do not consume veggies or anything with it. It is unthinkable for them to consume the full spectrum of food in one meal. Please stop this bullshit.
It bears repeating. A little bread, pasta, butter and animal fat doesn't hurt. It just makes life more enjoyable.
