Ketosis is a metabolic state in which fat provides most of the fuel for the body, instead of carbs. You can get into ketosis by following a very low-carb, high-fat ketogenic diet. In this video I’m going to look at whether this is a good idea or not.

  1. Good but not the whole story. The truth is that ketosis is a completely normal state, not an unusual one. Native Americans diet was almost solely Bison. Inuits had very little fruit and grain; their food was all hunted in the main. Hawaiians main diet was fish. Until agriculture carbs just were not available to evolving man all year round – how could they be? Fruits and grains are seasonal. In late summer and autumn more fruit, berries and grains became available so the bodies of the hunter gatherers would use those preferentially for energy whilst fat stores were laid down. Why? Because winter was coming obviously and lean cold times were ahead for a few months – they needed that fat.. The reason why we have seen the epidemic of cardiovascular disease, obesity, diabetes, stroke etc etc is because now refined carbs are available all year round and bingeing on those whilst frying in corn oil and using other "vegetable oils" trans-fats is a toxic combination. Ketogenic diet probably saved my life. There are plenty of cave paintings of our ancestors hunting. How many have you seen of him eating a banana? More accuracy please A N.
