Hey friends! As you might know, I’ve been researching fasting and practicing extended fasts for quite some time. One of the most common questions I see here is about how much weight people actually lose during extended fasts, and whether it's fat or muscle or lean tissue and so on.

So I built a calculator that estimates weight loss during extended fasts based on your physiological parameters, daily activity, and the number of fasting days. It breaks the projected weight loss down by tissue type - fat, protein, glycogen + water and gut content. The goal is not to predict exact results but to give a realistic physiology-based estimate of how weight loss may unfold during an extended fast.

If you’ve already done a 3+ day fast, I’d really appreciate your feedback. How close were your actual results (total weight, fat loss, or lean mass) compared to the projections from this calculator?

Curious to hear your experiences. Thank you in advance!
