50 pounds in 8 weeks is 6 pounds per week which is well beyond a safe level of fat loss (without medical supervision and extenuating circumstances or surgery).
You’ll be left with a lot of flappy skin too.
“Not spending a lot” wouldn’t be worrying about that, you’re not going to be eating.
Unless you’re a huge person to start or have massive water weight you don’t. A pound of fat is approximately 3,000 calories, so you would need an almost 3K deficit every day to drop that, and since most people eat around that much as their normal intake that’s an extreme amount that could be deemed starvation.
Now if you happen to be huge where the normal body functioning uses well past that then maybe, but if you’re anywhere below 300 lbs that would be a crazy amount for 2 months.
Nothing, it’s just a bad idea
Also, just go see a doctor, because each situation is unique and it’s stupid to believe the “calories in calories out” shit
What is the “calories in calories out” shit?
Ignoring metabolism and focusing solely on food calories consumed and exercise calories burned.
While calories are basic physics/chemistry/biology, they say nothing about the health of the individual. Not eating anything for a month to burn through your fat reserves isn’t going to leave you thin and trim.
That is metabolism. CICO will make literally anyone gain or lose weight. Nothing in the universe violates thermodynamics. You maintain a healthy caloric deficit and lose weight. End of story.
Not eating anything for a month is an eating disorder.
The big difference is the effect of a calorie for each person differs. How the body chooses to burn a calorie differs. If person A reduces their diet by 3000 calories in a week they might lose a pound. Person B might not. CICO is literally thermodynamics, you’re very right. How our bodies react to thermodynamics varies quite a bit.
