One of the functions of insulin is decreased lipolysis – reduction in the conversion of stored lipids into blood fatty acids. Decreased insulin causes the reverse.

Meanwhile, if you follow PB or Crossfit, you know that you have enough glycogen on a low carb diet to get through any CF workout, regardless of how intense, because it’s over quickly. Then you burn fat the rest of the day as your body makes ketones and/or any added glucose it needs from dietary protein (or muscle).

True but what size were these people? Modern day hunter gatherers are very small. The men probably weigh less than 140 lbs on average.

Also, what is their activity level? Walking around looking for food with the occasional sprint. Pretty tame by today’s standards of Crossfit and other programs which demand a high anerobic load.

You need carbs to do anerobic work.

Can blood type also dictate which way to lean towards (high carbs [from fruits & veggies], moderate protein VS low carbs, high protein) when looking to eat healthy, such as a study from Peter D’Adamo, ND, suggests, or is his research somewhat flawed due to the mold & fungus factors in grains & meats (grain-fed animal meats anyway)?

Also, are coconuts a good source of balanced carbs & protein, or does the laxative like property outweigh the nutrition?

God bless!
