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?

  • My first thought is it takes weeks of an extremely low carb, high fat diet to actually get in to ketosis. You'd never reach that state doing this. – DeeV Jan 20 '17 at 16:21
  • Out of curiosity, I tried ketosis a year ago. It took a few days of no carbs. Say if I eat slightly more carbs than my threshold for ketosis, then surely I would go in and out of ketosis during different times of day. – John Spence Jan 20 '17 at 16:46
  • Did you use ketone strips to test it? Most of the people I've met who practice ketosis took four to six weeks. – DeeV Jan 20 '17 at 17:25
  • Yes I did use the test strips. I thought that it takes a few weeks to be adapted, to get over the keto flu. But not very long to go into ketosis. – John Spence Jan 20 '17 at 18:16
  • Why you want to do this? What are your stats and what are your goals? – wdika Jan 20 '17 at 18:21
