Fats and oils paralyze insulin reception. Sugar increases insulin sensitivity, thereby, less insulin is needed. Dead flesh has the fats. Plants have the sugar. I'll take plants, thereby, still rock out single digit body fat, high energy levels, lean musculature, strength, endurance, and the sweet aroma being emitted from my person that the chickies love.
Meanwhile, you dead flesh-eaters will increase onset of morbidity, obesity, rot breath, and dead carcass odor.
