After another alcohol and chocolate fuelled Xmas, I believe I am still feeling the benefits of my Ketogenic diet experiment of May to July. The keto diet is 75% fat, 20% protein and just 5% carbs which has the effect of switching the body into burning ketones for fuel instead of the normal Western source, sugar. At one time, people in the northern or southern hemispheres would have entered ketosis during the winter months, living off stored fat from a carb-filled summer and mainly eating livestock or game. Of course, these days, a supermarket on every corner takes away this important, annual, physiological process. But switching to a keto diet by force teaches your body about this process again and it doesnâ€™t forget about it easily! I am virtually incapable of gaining weight, even after several blowouts of gigantic proportions along with booze, chocolates and mince pies.
