Carbohydrate (sugar) spikes blood sugar. High blood sugar stimulates insulin production and promotes an insulin-dominant metabolic environment. Insulin dominance promotes energy storing, hunger, and over eating among other things. Fat requires virtually no insulin to mobilize and has no impact on blood sugar, making it metabolically neutral. Deriving the bulk of your energy from dietary fat and eliminating most dietary sugar causes your body to elevate glucagon levels in response. Glucagon encourages glucongeogenisis (the synthesis of amino acids into blood sugar), the use of stored glycogen in muscles and liver, as well as lipolysis (body fat burning).

Glucagon is the antagonist to insulin; the two hormones are completely oppositional in nature. When one elevates the other is lower, like a see saw. Insulin prepares us for the famine, and glucagon allows us to adapt to it. Insulin stores food you give it and begs for more, glucagon nixes hunger and encourages self-cannibalization. Trying to lose weight when eating a low fat and high sugar insulin stimulating/fat storing diet is kind of like trying to run a race with your foot bound to a cement block. Its torturous, and needlessly so.

Since we don't run into many famines in america , it is wise for individuals to strive to be in a state of relative glucagon dominance. Starvation isn't a threat and most people barely do more activity besides moderate walking. There is no need for the majority of people to eat foods which promote energy storage. That said, eating a high fat low carbohydrate diet promotes glucagon dominance. A low fat high carbohydrate diet promotes insulin dominance. Eat this way to maintain your weight effortlessly; eat low fat if you want to feel the character-building pain of brutal deprivation, starvation, and fruitless efforts. ... an easy choice as far as I'm concerned .
