So the other day, I thought that it was time for me to move over to a different way of fasting, specifically the 18:6 TRF regime. Well, that was a mistake for me. I’m not sure what went wrong, but I ended up eating much later than I had been on the circadian rhythm plan that I was following. It might have had something to do with the pulled pork that I made on Saturday night?

From today, I have decided to go back to CR-TRF.

I’m moving across to a slightly more restrictive fast. The 18:6 TRF (time-restricted feeding) helps rid the liver of more glycogen, allows the body to begin using ketones for fuel, and can activate autophagy to rid my body of damaged cells.



Is body weight affected by when you eat? Here’s what science knows so far

Most diet and health advice is broadly based on the assumption that a calorie is a calorie (and it doesn’t matter when they’re consumed). But some research suggests that our bodies actually use calories more efficiently when consumed in the morning as opposed to the evening. This points to a strategy that could be beneficial for weight loss.

While there are many reasons for this phenomenon, one may be our circadian rhythm. This is the natural, internal process that regulates our sleep-wake cycle over a 24-hour period. Not only does our circadian rhythm make us feel tired at night and alert during the day, it also regulates the timing of the body’s processes – including digestion, metabolism, and appetite regulation – by secreting certain hormones based on what and when we eat, our physical activity and time of day.
