Considering the fact that man has sharp teeth in front, at both sides pointed teeth, and in the rear of them molars; that his stomach is adapted to the digestion of both vegetable and animal food, and that his intestine is so constituted as to be able to digest and change into blood both kinds, we can no longer entertain any doubt that nature herself bids him to change his food constantly, and to take in such as is of the most varied kind. if, in addition to that, we recollect that exclusive animal food renders an animal wild, quick, and sly, while vegetable food makes it tame, enduring, and slow in mind, it will not be denied that food exercises great influence upon the nature of a being, and it will now be readily understood that it would be a sin, if man were to be forced to take uniform nourishment.

the example of the cat is very instructive; it teaches us that change of food has transformed her into another being, mentally as well as bodily. the wild-cat has short intestines and is an animal of prey; the tame cat has long intestines, and betrays her old character only now and then by cunning and slyness. we also learn from this, that variety of food produces variety of bodily and mental qualities; and lastly, it may be inferred that nature, having fitted man for this variety and given him such diversity of mental capacities, wishes also that his food be well selected and of the greatest variety.

Starting keto is a real eye-opener. A fog you didn't even know was there lifts from your mind. It's difficult to explain until you experience it. Your muscles will be weak for a few days, and that's normal. Your body has grown accustomed to cheap and easy carbohydrates as a fuel source. As you force it to convert to burning fat for energy there is a transition where the muscles are short on energy.

It doesn't work just tot eliminate carbohydrates. You have to have enough fat. If you eat all lean meat (chicken, turkey, etc.) your body will use the protein as an energy source and that's not as potent as using fat for energy.
