Randomly decided to start eating one meal a day (for autistic reasons, not losing weight) and couldn’t find any guides that don’t devolve into “it cures cancer”.
I’m doing mostly fine, but I don’t want to learn that I accidentally screwed my health by doing something very wrong way after the fact.
In intermittent fasting when you eat one meal a day you only do it for two days out of the week, and the rest of the week you eat normally. Even when you split your day 18/6, not eating/eating, the 6h hours allows you to eat two meals a long time apart. Enough time for your body to process the food and absorb the nutrients, and ready to get started on the next batch when you eat before the 6h is up.
I guess it depends how much you have in reserve. OP said he’s not doing it for weightloss. If someone who maintains normal weight by eating normally, cutting that down drastically and suddenly might negatively affect them.
I was mostly talking about how it might make one feel.
