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

July 7, 2022 | 3729 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. If I am 5’4 56kg now and go on is this 800 calorie how much should I expect to lose? I do a lot of cardio everyday.

  2. Hello. How much weight can i lose in a week not eating at all. I saw where you said that was stupid but my situation is complicated. Im love sick right now three days ago i found out my mate of 5 yrs and 2 kids he cheated on me i have been love sick one time before i had no appetiate for over 2 weeks but i went to the gym and ended up going down 2 pants sizes. This time i havent eaten for 3 days only been drinking water.and going to gym.

    1. Hi
      I was once in your situation. Trust me. I nearly ended up in hospital because of it. The plan above you will work. Do it on and off (one week on one week off). I won’t lie. you will lose LOADS of weight. BUT after that week, your metabolism slows down. And will stop. Trust me you will put on loads and loads of weight as soon as you put one thing in your mouth. it IS NOT worth it. I hope you decide to follow my advice.

    2. Oh Hunnie . I was also love sick once , two weeks had passed before I realised I had hardly eaten . I did end up in hospital by the 4th week not eating . I was 58kg , four weeks not eating and a lot of crying I dropped to 46kg and my face caved in . It costed me a grand in botox and filler to lift and plump it , it took 8 weeks for me to be able to poo naturaly again and eat solid food. Don’t let your mate do this to you . Just munch some fruit even if you are not hungry . And take lots of vitamans

        1. This is great! I’m all in! And it is funny reading the coments! Maybe some people ant absorb or need to reread! Lol! Going to Canada, to meet new family! I do better on a last minute make it happen plan any way! Thanks so much! Janelle!

        2. Oh my… I feel your frustration Keith! I read the article and it couldn’t be any simpler. I’m in disbelief reading some of the questions people are asking. You have more patience that I do! 🙂

          PS – thanks for sharing the article. I’m starting today.

  3. So you’re saying in Mark’s case that he’ll really get down to about 177.5 from 180, and the rest will be water weight? so how is this better than any other program where you can lose 2-3 pounds per week?

  4. Hello I am 216 lbs 5 feet 5
    I want to do this 800 calorie count for 1 week
    Starting today because I am 216 can I do this for 2 weeks instead of 1.

    You also recommended
    Veggies
    Protein
    Liquids
    What kind of proteins from lean meats or
    Vegetable proteins ?
    Also because I am 216 lbs do I have to work out
    Or can it still be effective if I don’t work out and
    Take a 20 min walk each day 3 -4 times ?

    1. Um you HAVE to work out, there’s no cheating the system. If you want to be in shape and healthy the only way to do that is through diet and exercise.

  5. Reading these comments is completely excruciating. I guess most of these people are illiterate and couldn’t read all of this… and that is also why they don’t seem to be able to write very well either. Keith, it sucks that you have to re-answer everybody lol. Thanks for the help, good stuff to know.

    Margo- Don’t be a pansy. Move on.

    1. In the morning or as early as possible. The later you eat in the day the less time you have to burn it off, especially if you eat and then go to sleep immediately after, that can cause major weight gain.

    1. Because you’ll be slightly of me very week you’re eating about half of what your body needs , you’ll pass out.

  6. I read it and the comments. . Lol.. I’m going to try this as I love a challenged . It sounds safe and iv got 5kg of baby weight to loose *baby is three now * just looking for some thinsprasion . Will let u know in a week !

  7. WOW!! After reading the article, and then go on to read the comments, it is rather comical!!!! People ask the dumbest questions. If they took the time to read the article instead of asking the question, they’d see their question being answered, without making themselves look stupid!!
    Although, I think 800 is way to low, it may work for some, but not everyone. Keep in mind if you have any health issues, as well. I’m thinking this is just a quick fix to lose the weight. If you don’t watch you’re eating and drinking, you’ll gain that weight back.
    Good article otherwise.

  8. Omg the comments are killing me. XD

    But actually, this diet looks like it could work. I eat insane amounts of protein anyways. I’m going to start going 800 cals one week, then 1200 cals the next week. Both with plenty of exercise. Then repeat.

    Great article, thanks!
