I am a 43 year old man. I am 190cm tall and 85kg. I am slim with some belly fat. I am active, I do regular exercise and martial arts. My goal is to improve my general energy levels and sense of well being. I am also hoping to loose visceral fat and increase subcutaneous fat, and increase testosterone and growth hormone.
I have recently tried intermittent fasting, by delaying breakfast by 2 hours every day. I have a 16 hour period in the night and morning when I don't eat. I have also cut down on carbs a bit.
I feel very good and have more energy in general. Although I feel light headed and I little shaky in the mornings before breakfast.
I am interested to know if there maybe any benefits to cutting carbs even more, to the point where I would go into ketosis or semi-ketosis every morning before breakfast. I would then carb-up a little during the day, but by just the right amount so that I would go back into ketosis the next morning.
Is this a know diet strategy?
If so what might be the advantages or disadvantages of this approach over a constant keto diet or over a non-keto low carb diet?
