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've heard it said that a healthy target is around 1 lb per week. Maybe 2 if you're very obese, but at that point you really should be doing it under medical guidance.

In any case, the best way I've heard (outside of drugs) is to get an app that helps count calories, set a realistic daily caloric target and exercise schedule, and stay on it.

19

Consistency is key. For many the problem is they think of it as something you need to do for a while and then go back to 'normal' when really you should be looking for a new normal.

Apps can help, the best one is the one you actually use honestly and routinely.

Macrofactor. Helped me lose over 10 pounds and keep my weight stable once I was at target.

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.

44

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.

34

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.

19

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.

Losing that much weight in that amount of time means you have a critical medical condition. However in two months you can easily learn better, healthy nutrition and become more active, even have a lightweight exercise program. This will serve you better in the long run. There is never an easy way to become more healthy in a short term, except death.

15

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.

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.

Turns out, there are people who practice that sort of extreme fasting. BTW going back to normal eating doesn't happen in a day.

feddit.uk

I'm aware of one case where a man lost a ton of weight by fasting for several months and maybe taking some supplements but that was done under medical supervision. It can definitely be done but it's dangerous.

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.

12

Outside of necessary amputations or liposuction, there's no healthy way to do that. Especially in a way that's sustainable.

lemmy.world

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

In the context of human energy use it's also extremely simplified. Energy in can be measured in terms of food, but that assumes all calories are absorbed. It also assumes exact efficiency. It assumes average energy use etc.

As weight loss drugs show, for many who struggled with weight loss before, it's also important how the body uses, stores and distributes the energy.

Sure, no energy is created or destroyed, but dietary makeup, hormones, metabolism gut motility, gut biome, etc all have an effect in the process.

5

Well scientifically it is exactly calories in to your metabolism vs calories burned out.

Whether your body is absorbing those, or too depressed of a system to burn at a normal rate would be the doctor's investigation.

20
lemmy.ca

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.

lemmy.world

What you're describing is basically your metabolic rate. Everyone has a different one. If yours is super efficient, you need to eat less than other people.

That's the whole story. You can still reduce calories to lose weight. It's literally the only way.

If it's impossible to lose weight and still eat sufficient nutrients to survive, then you are one in a million and go see a doctor. Everyone else, start adding vegetables and fiber to your meals.

What I'm talking about but maybe didn't do a very good job of explaining is metabolic adaptation. It can take months before your body adjusts, before you figure out what calorie deficit is needed and it varies wildly from person to person. Our brains can burn calories to be more creative or slow down to preserve ideal body weight. Which can negate a wide amount of calorie usage. https://www.sydney.edu.au/news-opinion/news/2023/07/05/its-time-to-bust-the-calories-in-calories-out-weight-loss-myth.html

Yep, it takes a while to figure out where your calorie intake should be, and it changes over time.

But to be clear, in no way does that mean some people can't lose weight with a calorie deficit. It means it's complicated to find your deficit, and you won't ever get nice linear progress. I think a lot of weight loss problems are because people get sold on diets and expect steady results. That's not real.

This isn't a diet. If someone wants to be fit, they need to learn to eat like a fit person because one day they'll be a fit person and then they'll have to maintain that. Forever. So no keto. No carnivore. No intermittent fasting (unless you really can do that forever. I'm going on 5 years). Just eat more fiber, less calorie dense things, and find things you like that are sustainable for you.

Sorry, just realized I'm ranting. This is one of those topics that gets me going because there's an entire industry designed to make you lose weight, gain it all back, and suck the money out of your wallet in the process. It doesn't need to be like that. It's not that complicated. There's no trick to it.

Napkin math: There are roughly 3,500 calories in 1 lb of fat. To lose 50lbs of fat, that's 175000 calories.

Let's get an upper bound of 31 days per month, for 2 months, that's 62 days. 175000 / 62 approximately 2822.5 calorie deficit per day required. The actual number would be higher.

The other aspect of this is that, generally speaking, the majority of "quick" weight loss is pretty much always in the form of water loss. Water weighs around 8lbs a gallon. So, you'd need to drop about 6 gallons of water to achieve that kind of weight loss.

Neither of these are safe, reasonable, or practical in that time frame, for the average person without medical supervision and/or other professionals supporting you.

I had weight loss surgery ~2yrs ago. Started out at ~335lbs and have lost ~100lbs. Most of that was lost slowly over the course of the first year after the surgery.

So, even with weight loss surgery you are unlikely to loose 50lbs in two months. Unless you are starting at a very very high inital weight.

Or for a legal option, you can walk in to most weight loss clinics and they'll give you all the robin eggs (phentermine) you want. They're also great for long road trips.

Daily exercise counts a lot too. Get a heart rate monitor and get into zone 2 for 150 minutes a week, it's hard to describe how much of a difference it makes through your entire body.

feddit.uk

Working out has a lot of positive health benefits but it plays just a tiny role in weight loss. It's virtually all about diet.

2

I can't speak for anyone else, but physical activity acts as a mild appetite suppressant for me. So it reduces calories in while increasing calories out, with the former being more significant for weight loss.

1
lemmy.ca

Daily exercise only counts if it’s cardio and not muscle building. Otherwise the fat gets converted to muscle, which weighs more than fat.

Of course, weight loss shouldn’t ever be considered the end goal, and building muscle and having your weight go up/stay the same is perfectly fine to become healthier.

1

This is so wrong it hurts. Your body cannot synthesize muscle from fat.

1

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.

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.

Intermittent fasting, only eat from 10am-6pm.

Early morning exercise, 1hr of walking or cycling. Start 5am or 6am. Medium intensity.

Generally healthy meals. No calorie blowout days.

Plenty of water, minimal fizzy drinks. Soda water is OK.

For added benefit, afternoon HIIT.

Worked for me.

You lose about a pound a day water fasting, but its hard mentally and physically. As in if you've never fasted before, its gonna be hard to keep going the first 24hrs. If you're obese you have a good chance to come out just fine. You can look up the electrolytes y o u need to do an extended water fast. You should be getting checked out by a doc frequently while doing it. Things can go bad really quickly. Read, read, read everything you can before doing this.

A Protein Sparing Modified Fast(PSMF) is where you eat about 600 to 800 calories a day with about 120 to 150g of protein (chicken breast) with leafy greens( broccoli, spinach, kale) the veg is so low calorie it doesnt really matter the amount as long as its at least a cup( you need the vitamins, minerals, and fiber). the protein so filling you basically are gonna be "full". you wont be satisfied, but you will be able to eat and never be looking for more. the point is to have enough protein intake to keep your muscle loss to a minimum. You have to do a basic weight training or calisthenics regimen to keep the muscle loss down.

  • Take a multivitamin
  • if your having trouble shitting, more veg
  • lightheaded: pinch of salt in a glass of water, broth, or buy what is called lite salt here( its a mix of sodium and potassium salt; you need both types anyway)

Go to your doc and tell them your plan. They will take blood exams, probably EKG, and check ins every 2 or 3 weeks to make sure everything is OK. I've done PSMF because my sleep apnea was literally killing me. I lost 25 lbs the first month and 20 the next. It sucked, but it fixed my apnea and all my cardiovascular and metabolic problems. I then gradually raised my calories to 1800 and kept losing weight until I got to a normal weight.

You will have loose skin, lift weights and fill out with muscle to help with it. If something feels off, wrong, hurts, etc. Stop and go get checked out.

This is about the only right answer here. I am currently doing something very similar to this, but with some days where I eat more. But even going to this extreme, you probably won't be losing 50lbs in 2 months.

I am also exercising. Zone 2 walking and weight lifting to maintain and build muscle.

You could try a 3 day fast as well. A full 72 hours. Only water, coffee, or tea. No cream. No sugar. No nothing. See how well you can get through that.

Even with my modified diet, it can be very difficult at times. I am also being monitored by a doctor where I check in every 2 weeks or reach out if I have issues with anything. So, I am being heavily monitored right and would not recommend this method without a doctor present.

A simple start for that is skipping either breakfast or dinner if stricter rules would be hard to follow.

If you eat lunch at noon, dinner at 8pm, and you don't eat outside the afternoon, that's immediately a 16-8 IF.

But a pound a day seems like a quite drastic target nevertheless. Smaller changes are way more sustainable long-term

4

I do breakfast at 7, small snack of nuts at 10, lunch at 12:30, small snack at 2, dinner at 6, and absolutely nothing after dinner.

Meal volumes get adjusted depending on what I’m trying to do with my weight.

That 7-7 fast gives my body time to properly digest food and means my cholesterol spikes properly when I do eat food. This means fewer cravings, so the entire process becomes easier.

2

You don't. If you're serious about weight loss you need to commit long term.

3

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.

lemmy.world

Assuming you're a male, you should not drop below 1500 cal a day, it can cause permanent issues.

2
lemmy.world

Really? Somehow I doubt that. I'm short (165cm) and I believe I can run below this threshold just fine.

2

It does depend on your tdee total daily energy expenditure and BMR base metabolic rate but all the legit info you can find would suggest you talk to a doctor before going below 1500. If I recall correctly you can start to lose muscle and bone density, and bone density doesn't come back.

1

It's technically possible by water fasting for 2 months, but that is pretty dangerous for so long and you would need a strict vitamin and salt intake to even have a chance of doing it safely.

Definitely not a good idea, certainly not without doctor supervision.

1

Pick up a 1lb bottle of water and drop it once a day, every day, for 50 days.
You might be able to take a few days off, since you have more time remaining.


IDK man if I lost 50 lbs of stuff out of my body, I'd probably be in the ICU.
