Let’s say you burn 2,000 calories just existing (literally no movement, just lying in bed for 24 hours straight).
2,000 cal. x 30 days = 60,000 cal. burned.
60,000 cal. divided by 3,500 cal. (one pound) = 17.14 pounds lost over 30 days.
That’s not factoring in water weight or extra calories from moving around on a daily basis.
I know this isn’t a direct answer to your question, so I apologize, but I am the same weight (or at least started at that weight 3 weeks ago) am 5’9”. Did a 3 day fast and then immediately started OMAD Keto.
Based on my experience I really believe the better option for weight loss is OMAD Keto rather than very long prolonged fasts. I am angling on this purely from a lifestyle sustainability point of view. I still get to eat except I can eat all I want, feel full, and still have a caloric deficit. It might take twice the time to lose 50 lbs, but it is less strain on my system than doing a 30 day fast. There are definitely benefits to prolonged fasts, but they go beyond weight loss. For a focus on weight loss I really believe OMAD Keto is the best method when considering every aspect.
Depends on the person and how much fat they have on their body. I lost 30 pounds on a 30 day water fast.
You can expect to lose a good amount the first 5-10 days and then it slows to about 1 pound a day unless you’re adding in lots of exercise.
If you burn more than 3,500 a day it’s more than a pound of fat a day.
The more active you are the more you’ll lose. Imagine doing the rocks work out while fasting.
There’s no exact science to it. Calories in a food are determined by setting fire to the food and seeing how much energy burns. Were working with rough approximations and a lack of understanding of people’s differing contributing factors.

Experienced faster here, currently on day 6 of a 7 day fast.
For pure fat loss, you are much better served by a combination of weekly 48s, 1-2 72s per month, with OMAD, a moderate calorie deficit, a strict ketogenic diet, and a progressive overload strength training regimen.
A 30 day fast is highly catabolic, and will result in significant muscle loss. The more obese you are, the less catabolic it will be, but any prolonged fasts beyond about 96 will be catabolic enough to make them not worth it from a muscle loss standpoint more than 1-2 times per year, and even then, one should limit the prolonged fasts to about 5-7 days. I might need to spend a month or two to regain the strength I am losing in this 7 day fast, for example.
Fasting is muscle-sparing, but only to a point. The optimal muscle sparing fast is 48-72 hours for those who are strongly metabolically flexible, in ketosis most of the time, and going into the fast in nutritional ketosis. If you are still on the fat adaptation journey, not metabolically flexible, and/or going into the fast having eaten carbs beyond a strict ketogenic diet leading up to the fast, that optimal muscle-sparing zone will be more like 72-96 hours.
