Anyway, I have been doing 23/1 IF since, and I was pleasantly surprised that my glucose tolerance was considerably higher. In line with diurnal cortisol, I have been waiting until 4pm-6pm in the evening and then consuming all my calories in one large meal, ive even been sneaking in some carbs in the form of candy and banana's. Im also taking 1000mg metformin with the meal, and pre-loading with 2 teaspoons of white wine vinegar.
I dont restrict myself, I dont count calories, I just eat whatever I want and eat to hunger. My estimate is it comes out to about 2200 calories.
My plan was to continue this for a few days until I became accustomed to the circadian rhythm of feeding, and then transition more into a ketogenic diet but still keeping the 23/1 feeding pattern. I needed to eat higher carb and bit of junk food in the beginning to keep myself satisfied and not strain myself with cravings while my body adjusted to the new 23/1 pattern because ghrelin is also on the circadian clock and it takes time to adjust. Eating ketogenic on 23/1 will inadvertently lead to reduced calorie intake because it wont be easy eating 2200 calories of low-carb in one meal, not unless I start drinking pints of cream.
OK, so yesterday was my first low-carb day on the IF 23/1 and today I had some comments from work colleagues "hey it looks like your losing weight", tbh my trousers do feel noticeably looser. Great! I never weigh myself on the scales because its just playing mind games with yourself, I just go by how I feel and how my clothes fit. I actually did 23/1 back in 2007 and looking back now I remember that's when I also managed to get down to my lowest weight, alas, everything literally went "pear-shaped" though when I started my new job and came under stress and pressure.
Stress and depression make me crave sucrose laden foods. This has been the prime reason I have yo-yo dieted so much. Sucrose is how I artificially raise my mood to cope with stress and depression. Although sucrose tends not to make me gain weight in small amounts, once I get the mood high from sucrose foods I end up binging on huge amounts and its very hard to pull myself away from it.
I cant eat just one strawberry lace or just one drumstick lolly, as soon as I get the taste of sucrose on my tongue I just get completely mind-controlled and consume it all. I.E. hyperphagia , Fruit does not have the same affect at all. Only human engineered foods cause these addictions.
I want to quickly comment on something else aswell, Today I had only bacon and eggs for my meal. Anyway about 30 minutes after the meal I got very drowsy, and it was lights out, I must of napped for about 1 hour. This is post-prandial somnolence, and I was surprised that this happened because I had assumed this phenomenon was primarily a function of the tryptophan:LNAA ratio in the blood, and that only high carb meals that spike insulin were capable of post-prandial somnolence by shunting more tryptophan into the brain.
Sigh, so thats another theory out of the window. Unless the egg white had something to do with it? I ate 4 egg whites in the meal, and egg whites are high in tryptophan ( but they are high in BCAA aswell! ). This study used something called hydrolysed egg protein to raise the tryptophan:LNAA ratio. No idea what that is, and it probably isn't the same as fried egg whites. So meh.
Anyway, the rodent IF study has finally nailed it into my brain, that when you eat is likely just as important as what you eat. I'm sure I wont stay 23/1 forever, but I will keep the lessons that rodents teach us in mind. 23/1 is good for weight loss, and I will probably resume 2 meals per day in a 6 hour window in the future for maintenance.
hhhhmmmm, im sure the government nutrition guidelines of eating 3 meals per day must be causing more harm than good.
