Extreme Weight Loss (2022): How Much Weight Can You Lose In A Week?

July 7, 2022 | 3727 Comments


how much weight can you lose in a week without eating

Important note: Please advise your doctor before following any plan. Don’t follow the advice below if you are under 18. 

People always ask: How much weight can you lose in a week?” Well… to answer your question I have good news, awesome news, and bad news.

First onto the good news: YOU CAN LOSE A TON OF WEIGHT IN ONE WEEK

That’s right, you don’t have to be bound to the conventional wisdom of only losing 1 or 2 pounds a week. Extreme weight loss diets can definitely work, but only for a short period of time.

In fact, you can lose up to 15 pounds in one week if you do it correctly.

Now onto the awesome news: ALL THAT WEIGHT YOU LOSE WILL BE WATER AND FAT, NOT MUSCLE

Yup, you read that correctly, if you follow the methods at the end of this post, all the weight you lose during the week will be pure body fat. The conventional statement that losing more than 2 pounds per week leads to muscle, organ, and hair loss is absolute unicorn shit.

How do I know this? Because some awesome scientists from the American College Of Nutrition back in 1999, conducted a study, which tested 2 groups of people for 12 weeks.

One group only did traditional cardio, while the other group only did weight training. Both groups ate 800 calories a day. At the end of the study, both groups lost large amounts of weight, but the one that only did cardio lost large amounts of lean muscle mass, and the one that only did weight training didn’t lose any muscle mass at all.

So there you go, some hard hitting scientific facts that prove that you will not lose muscle during extreme dieting as long as you lift weights.

Note: And if you don’t have a gym membership or if you don’t have access to any weights, then doing a well-designed bodyweight program like Bodyweight Burn is your next best option.

And lastly, the bad news: YOU HAVE TO EAT VERY VERY LOW CALORIES

So yeah…. you have to eat a ridiculously low amount of calories to lose a lot of weight in a week. I’m talking along the lines of 800 calories a day.

The amount that would make any nutritionist hang themselves.

And now, onto the plan, but first, a picture of steaks:

I didn’t want to put a boring picture of a scale, so here’s some delicious steaks. I’m guessing this isn’t the best article to put this picture in

The 2-step plan to lose the maximum amount of weight in a week

Please note that the following plan can be used by both men and woman.

And don’t do this plan if you’re under 18, you’re way too young to be eating such low calories.

I guarantee that if you follow the plan below, you will lose 10-15 pounds(water and fat) in one week:

1) For one week only, eat 800 calories per day.

2) Workout 2-3 times per week with weights. Make sure the weights are heavy and be sure to hit all body parts.

That’s all.

Some notes/tips about the above 2 steps:

  • 800 calories is very little food, for any man, woman, or baby walrus. Because of this, I suggest that you only eat 1 meal per day a la Brad Pilon’s Eat Stop Eat. If you eat one 800 calorie meal per day, then you’ll at least feel somewhat satisfied, but if you split that up into 3 or even worse, 6 meals per day, then you’re not going to fare so well on this one week venture. Yes, this means that you will be fasting 24 hours every day for a whole week. Just remember, you will be burning fat, not muscle.
  • Whenever possible, eat higher protein and eat foods with high water content such as fruits and soups. Also, drink lots of coffee and green tea, since they both tend to blunt hunger quite well.
  • Stick with heavy compound exercises when in the gym. That means no curling and crunching, and if you even step foot on a treadmill, my dumbass radar will go off and I may have to kill you.
  • If you can’t lift weights, then your next best option is to do some sort of bodyweight training. You know…exercises like squats, push-ups, lunges, pull-ups, sit-ups, etc..
  • This is a mental game more than anything else. When you’re eating very few calories to lose weight faster, your mind starts playing tricks on you. Your stomach is gonna be grumbling more often. And there are gonna be times where you want nothing more than to self-sabotage yourself. Which is why the next point is so important.
  • Above all, keep yourself distracted and out of the kitchen. If you’re constantly prancing around the kitchen and thinking about food, you’re going to fail. So keep yourself busy. Read a book, play some video games, take a nap, work on your tan, or shave your pubes. I don’t care. Just do something that doesn’t involve food.
  • [EDIT 10/6/2014] I should also add that your protein intake needs to be HIGH. Like really high. In fact, the majority of your calories should probably come from protein, fruits, and veggies if you want this diet to be effective. The protein will help keep you full but more importantly also help maintain muscle.

Remember, this is only for one week

I just wanted remind you all, that this sort of extreme weight loss plan is only a temporary plan.

The results don’t have to be temporary, but the plan is. Please do not try and do this weight loss plan for more than a week.

Doing so is really going to mess with your head and you’ll most likely binge back to your original weight.

After one week, transition to a more moderate weight loss plan for the long haul.

I hope you guys now know how much weight you could lose in a week if went balls to the walls.

Want even better results? Take it to the next level with Fat Loss Boost

Many people have been asking me, “Can I do this for more than 7 days?”

Uh…

Yes and no.

Technically, you could eat 800 cals per day for a sustained period of time.

But sooner or later it’s gonna backfire on you.

If you want a more sustainable rapid fat loss plan…

Then I highly recommend checking out Fat Loss Boost.

This is a more long-term approach than the strategy I outlined in this blog post.

It’s a strategic rapid fat loss diet that works in 14 day cycles.

So you go hard on the diet for 14 days, lose a crap ton of weight, take a break, and repeat.

And the results from Fat Loss Boost are even better:

“I have been able to lose 10 pounds using this program. Starting weight 186. Weight this morning was 176.”

“I lost 12 lbs for my first attempt. Started at 201.7 and ended at 189.9. I am amazed!!! Thanks to everywhere for all the support and great hacks.”

“Ok people I’m done 😀. I hit 171.8 today, my goal was to break 172 on this round which was what I weighed almost ten years ago (lowest as an adult). That’s 30.2 lbs in just under 3 months.

Pretty crazy, right?

Definitely give it a look if you want a realistic, yet challenging plan that burns fat faster than anything. you ever tried before.

  1. Hello!
    I notice you say don’t do this if you are under 18 years of age. I was wondering if you had a plan of sorts regarding what a person a little under the age of 18 could do to lose a quick 5 pounds or so in 10 days? Safely(ish)? I’m already at my goal weight, but the holidays are coming up! We eat a TONNNNN over the holidays. So, I was hoping you maybe/possibly had some suggestion to lose the five pounds that I will gain so that I can still stay at my goal weight!!
    I know, silly, and a little irrelevant. Maybe you can help me out? 🙂 Haha.
    I’m 5’7 and 120 pounds. Just want to be able to stuff my face with the knowledge that I won’t be going completely bacbackwards!
    Thank you so much if so!!!!

  2. I have to say I don’t plan on doing this jumpstart diet due to the fact that I only need to lose about 20 lbs. That being said I just spend about an hour reading a ton of these comments and this was one of the most amusing reads I have come across in a long time! The amount of people that just didn’t read the article was astounding! Keith, I respect you so much for responding to as many comments as you did and I plan on reading many more of your articles! Thanks for being so awesome!

  3. im not fat, just slightly chubby. losing 10 pounds would mean i get into perfect shape. would this plan help me lose 10 pounds in that week? or will only overweight people lose that much?
    thanks

  4. What would happen if someone does something as you suggest ,but eat just less than 200 calorie per day for one week. My daughter has started this diet and eat very little and not dense in protein, since she is vegan. She exercises every day for 50 minuets boxing, weight, and cardio.
    Would you tell me what would happen to her body if she goes more than one week?
    She feels some crumbling in her stomach already and that made me worried.
    Thanks

  5. I need to lose 30 pounds and I need to lose it as quickly as I gained it. This past July I was 112 pounds at 5ft3in after working for a couple months to get to that weight from 125. Somehow, recently I gained an incredible amount of weight and am now almost 140! I blame eating crap food. I have never been at this weight before in my life without being pregnant. I am literally disgusted with myself. I started eating only 800 calories two days ago.I have been a bit hungry but I’ll deal. I have always been skinny. My average weight was always around 105lbs wearing a size 3 jeans. I will get back to my old self if it kills me. Hopefully it won’t be too hard. What tips would you have for someone like myself? How much can I expect to lose with the 800 calories a day? Also. Is there any side effects to this diet?

    1. You’re looking for a “quick fix” and people who do that never get long term results.

      This is just for a week, after that you need to transition to a diet that’s more sustainable. Long term, u can do fine eating about 1400 cals per day.

  6. I love this article.. So let’s say I only have to lose about 8-10kgs and have only 3-4 months to do it, how many calories should I consume in a day and what type of exercises should I be doing? (Female, 35years old)

  7. hey i am right now 69KG im a short dude im 1.63 so i wanna lose fat and be 63 to 65 KG wil this diet help me lose all that in one week?? and i dont go to the gym i do body weight training is that enough..?
    and are you sure i wont lose muscle ?? im from holland sorry for the poor english

    1. Whatever you did to build and maintain your current levels of muscle, you neeed to continue doing that to maintain it even if you go on a lower calorie diet like this one.

  8. I am a 34 years old male, 250 pounds right now and I need to get rid of 60 pounds minimum to get the job I am interested in for years (never thought I would get a offer and got fatter and fetter) the time window is pretty small so as everybody I need to have it happen fast (6 month max). I am willing to put maximum effort in that task but I am confused cause some are telling me to eat around 2500 kcal per day and some say 1600-1800 kcal per day.
    Thank you so much

  9. I am currently a female who weigh 205. I’m having a birthday party In two weeks if I do the 800 calorie diet for a week I can lose 10 pounds? But after the first week I have another week to go and you said it’s not good to do more than one week so what should I do the next week to continue to lose weight? Can you give me a idea of how much weight I can lose…
