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?

What would be the point, you want to lose fat not water? As soon as you eat again you'll regain the water weight you lost.21 -
Depends how much you eat when you eat...4

It's up to you. If you find it easier, you can not eat 1 day a week and eat at maintenance the rest of the week. Then you'd lose about a pound a week on that maintenance level. The trick is not to eat more the day after because you're starving!7

Not enough to matter, and and without a real plan you may end up eating that back anyway.10

Your questions don't make sense. You will have a much greater chance of success if you educate yourself on how weightloss works. MFP is a great place to learn.
"Intermittent fasting" is getting traction. But 14 hours of not eating isn't even considered "intermittent" fasting.
You don't starve yourself for a day. That is called fasting for a day.
Not eating for 24 hours is okay for most healthy people. But people who have a difficult relationship with food, should probably aim to eat more regularly, instead.
Your weight fluctuates from day to day, so you can't measure true weight gain or loss in one day. You will lose 2 pounds of fat in a week if you have a 1000 calorie deficit every day. This sounds simple and it is, but it takes commitment, dedication, patience, knowledge, and actual, real guts.14 -
You did not provide any information, but lets make a few assumptions for you.
Say your maintenance calories are 2500. Thus you'd get 2500kcal less in a day. As 3500kcal equals 1lbs, you'd be 'down' about 2/3 of a lbs. However, part of this will be muscle instead of fat. Also, you might notice this on the scale as you digest less food. On the other hand a decrease in fibre, fat and fluids might has some adverse influence on pooping, and you don't notice any change on the scale.
In summary: totally useless, and a rather stupid idea. Sorry, mate.5 -
When I have done 24hr+ fasts, my weight has gone up due to stress on the body and water retention .... upon eating again and staying at maintanence I lost about 0.5lb ... so about 200grams
this was at 165lbs
so really not worth the effort if you are planning on it for a weightloss strategy6 -
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.3

Short answer.

Lasting weight loss happens over time. What you do over the next week and the next month and the next year consistently will have far more impact than what you do for one day.
You have a long journey ahead of you. Figuring out how to eat a filling, enjoyable, and practical diet that gets you consistently at the right calorie level is the single most important thing you can figure out. If intermittent fasting helps you do that then it's fine, but it really isn't about how much fat you can lose in a very short period of time.5 -
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.7

Why would you do that? Maybe you should inform yourself a little bit more how weight loss with mfp works, before you start inflicting more emotional and physical damage on yourself, no offense. You've been probably over eating a good portion of your entire life, and now you plan to fast for 24 hours or more to lose 2 more pounds of water weight. It's disturbing honestly.9

There is nothing unhealthy about a one day fast.2 -
Zero. You will lose zero fat.2

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.1 -
Why? it would just be water.1

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.3 -

That could be said of anything regarding eating.3 -
