Well - I don’t think this is healthy or possible in 2 months.

Last year, I weighed in at 242 with high blood pressure and decided to get serious about weight loss. I started tracking my input and output to my system. I have a watch that measures approximately how much I work off. I use apps to track how much I’m taking in. The one factor that is missing is your BMR, your basal metabolic rate. This is how many calories you burn just by being alive. There are special scales or devices that can measure this for you. You will need this to figure out the math.

Food calories eaten - BMR - Exercise calories spent = Calorie deficit or excess

So, if you exercise more, or eat fewer calories, you’ll lose weight.

So, a pound of fat is 3500 calories, so if you have a deficit of about 500 calories a day, that’s about a pound of fat per week. If you have a deficit of 1000 calories a day - that’s a lot! - then you might lose 2 pounds a week.

Using this formula, I managed to lose about 45+ pounds in 6 months. I worked up to a walk+jog and managed to cover about 3+ miles per day. Unfortunately, with the cold weather of winter, I’ve not been able to exercise much, so my weight loss stopped in December.

But what you’re talking about is losing 5+ pounds per week. That would require a 2500 calorie deficit! That would be a super-heavy workout every day. And then eating very sensibly. Even so, there is danger that some of your weight loss would be muscle and bone loss in addition to fat.

tl;dr - Don’t do this. Also, talk to a doctor.

Amputation

That sentence makes no sense. Figure out the amount you would need to eat and work out to MAINTAIN your desired weight and start doing that. Let it take however long it takes, then keep doing that to maintain, or tweak it to improve.

50lb in 2 months sounds dangerous as fuck. You could stop eating and probably lose that much, fuck up your metabolism, and immediately gain it back without even eating as much as you did before.

Trizepitide

Chop an arm?

It takes a deficit of about 3500 calories to lose 1lb. Let’s say you stop eating at all for those 60 days. Assuming you burn 2500 calories a day idle, then after 60 days you’d have burned 150,000 calories, which would lose you ~43 lbs. Also your metabolism would slow down if you stopped eating and would make you lose less.

I don’t think it’s possible without some kind of surgery, but that violates your requirement of not spending a lot.

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.

I lost 40lbs in 7 weeks. Would not recommend. It was from chemo and radiation making so that I vomited any food, and needed a liquid food pump inserted. Your body will be wrecked at that calorie loss.

50lbs is an unhealthy goal. Both for your mentality and for your body. Health recommendations put about 2lbs a week as the upper limit on weight loss without health issues. Even people who are on weight loss programs and injections are told to stick to this amount as best they can.

As someone who lost 50lbs last year I get the urge to just “get it done” trust me. But it won’t help long term. Pick a routine, watch your calories, and stick with it. Success comes from progress, not quick fixes.

And if you want my secret tip, you’re gonna be hungry, but when you do eat, shrink your serving sizes, and wait. If you’re eating don’t make a whole meal (ex. Two pb&js, chips, and fruit) make a serving (one sandwich, or just the fruit, or a measured serving of chips, don’t just eat out of the bag), eat that and some water, and give it time. You won’t be “full” but the hunger will go away and you can keep going.

Severe illness or a gulag.

50 lb over 8 weeks is pretty insane. 1 lb/week is pretty good. 2 a week is pushing it.

50 isn’t going to happen without consequences.

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.

If you stop eating entirely for 2 months you might just barely make it.

EDIT: Or sing up for the next season of Alone, which is basically the same thing.

I did a pretty extreme weight loss a few years back, and in two months, I lost 20 pounds.

Even that was a bit more than is recommended without strict medical supervision. Two pounds per week is kind of the upper bound of “normal” weight loss. Don’t attempt more without a very, very good reason, and an even better doctor.

1-2 lbs a week is the MAXIMUM you should be losing.

Find a TDEE calculator (total daily energy expenditure). It’ll give you a rough idea of how many calories you need to maintain your current weight.

Eat less than that. Weighing your food is critical or else you’re lying to yourself.

It’s near impossible to exercise yourself out of a calorie surplus unless you already do endurance sports and if you’re looking for drastic weight loss chances are you can’t handle that much cardio right away without dying.

All fad diets are a way to trick you into eating less than maintenance. Keto? You won’t be able to get enough calories - so you lose weight - although rarely some people manage to maintain on a keto diet. Vegan? Lose weight due to reduced fat intake and fat is calorie-dense. Intermittent fasting? Just hard to eat 3000+ calories in one meal per day.
