Feels great for health, not good for weight loss.
Fat loss is about hormones. Dry fasting is a good way to affect that but water fasting takes longer and if you are willing to fast all the way to 10% BF you will notice larger shift in your hormone sensitivities. Particularly related to satiety and hunger.
More time without the hormone = greater sensitivity to said hormone
We are already eating more than what our bodies need (Western diet) and when you fast you may be lucky if you bring down the aggregate calories intake to just what your body needs.
To lose weight you have to consume less calories than you burn. Fasting can only be one component of that. It accelerates processes but calorie input and burn rate are still the driving forces of that equation.
I think that dry fasting is not the straight forward short term hyper fast weight loss tool as people think. One can tell by the questions that reappear in this sub (“100 lbs in 2 months”, “how much weight loss with 20 day dry fasting” etc.)
You still have to think in the bigger picture, even more when your body is prone to holding on to water, because then it’ll mess with measures using the scale. And ofc refeeds and rehydration messes with the scale too, so in the end you have to give it time for water fluctuations to even out.
I think dry fasting is probably effective either used as tool to tear through stored glycogen faster to get into ketosis to switch into a longer wet fast. Dry and slow steady state cardio (basically walking for me) gets me into ketosis in 18h after a carb heavy meal. Or when you start the dry fast when already in ketosis and while maintaining ketosis during refeeds– that way shorter dry fasts could maybe bring more value. The shorter you keep it (24-48h), the more fasts you can chain and the more active you could afford to be. These are just my thoughts and not tested routines though. I’m currently experimenting to find a good routine for myself to get fat loss and a moderate autophagy effect.
