How much fat can I lose if I fast for a whole day?

I'm 294 this morning, was 297 yesterday morning before my 14 hour fast.

My maintenance calories are 3300, obviously most of that was water weight, but I'm going to try for a full day today to see what happens.

Anybody with experience on this?

    Depends how much you eat when you eat...

    First of all you are right you lost water and there is less bulk in your stomach and intestines. This is not fat loss. If you truly burn 3300 calories a day you could theoretically lose almost a pound a day but your body is going to consume more than fat which is why fasting for quick weight loss is not safe. Take your time to lose weight. You didn't gain it all in a day and you won't lose it all in a day. One of the many reasons we lose slowly is to reeducate ourselves on how to eat healthy. Fasting excessively to lose weight is not going to accomplish that and you are risking your health.

    Between where you are today based on your past and where you will have to get to in order to both manage to lose the weight you need to and maintain that loss.... you have a long way in front of you.

    Much of it behavioral and mental and overhauling how you relate to food (and various types of food) and general levels of activity and even exercise.

    Your current exploration? A dead end.

    Thinking of a sustainable way to create a ~20% deficit as compared to how many calories you burn each day for the next couple of years? Much more practical.

    You want simpler still? Figure out what a normal weight person (BMI 24.9) who is lightly active or even active and has your stats.... figure out how many calories they get to eat.

    Start there.... you can adjust later...

    And it is never too early to start practicing how you will have to eat and move in order to maintain...

    I have no idea, but I find this question slightly concerning. I'd look into some healthier weight loss options.

    There is nothing unhealthy about a one day fast.

    Zero. You will lose zero fat.

    You'll lose < 1 lb of fat if your daily TDEE is 3300 and you consume no calories. If you overeat the next day, you'll gain it back.

    You may or may not see a drop on the scales, since weight is more than fat.

    I fast for a day now and then for weight control and for the discipline of it. I like it. I've done it for decades. Not on a regular schedule, just now and then when I feel like it.

    Perhaps not in and of itself. Unless it triggers a binge-restrict cycle or is accompanied by other eating-disordered behaviors. Not saying that is the case with the OP (I have no idea) but it bears further consideration.

    That could be said of anything regarding eating.
