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. Are you legit an imbecile, eat only once a day ? That will fuck with your metabolism so much. Low calorie diets are bad as they are without idiots like you suggesting people go on 24 hr fasts whilst weight training.

  2. Hello

    I’ve done the 800 calorie a day for 5 days now. First 3 days were difficult but I was happy as I was losing about 2 pounds per day. Days 4 and 5 have been almost too easy as I don’t have that empty / starving feeling, however, I’m not losing weight any longer.

    Been the same last 2 mornings. I’m eating 4, 200 cal meals each day with protein from fish, chicken etc.

    I’ve done 2 workouts so far doing bench, deadlift and squat type exercises. Do my results seem normal so far? I’m down 5 pounds which rocks so just curious.

  3. Few questions:
    1. Can you drink diet soft drink or will this mess with it?
    2. What would happen without the weights? Is it ok?
    3. Does it matter if you eat some non-healthy foods as long as it’s under 800cals in that day?

    1. 1. no
      2. you lose muscle
      3. I wouldn’t, since you’re sticking to such low cals already. It’s not a wise thing to do.

      1. Hi Keith,

        Just my curiosity, why cant you drink zero cal soft drinks?
        how much weight would i lose over 6 days doing 1-2 hr work out per day and limiting cals to 800 or less – up to 15lbs – is that correct?

        1. Yo nat! I’m Tryin To Do The Same Activity As Yours..And Have To Lose 15 kgs too.I Reas It In An Article That A Person Can Lose Up To 3-4 Kgs Of Belly Fat If He/She Restrict Their Calories Intake To 800 and low and do some exercise..So Best Of Luck! and lets both get started

  4. Hi, I have read the article 3 times as well as many of the comments, but I’m still not certain as to the order of this programme. My plan now is to eat something small for breakfast, e.g. 100 calories such as nuts and grapes, then have a 600 calorie lunch, e.g. turkey, beans and veg, then a low calorie fruit in the evening – keeping to the 800 calories as best as I can. I am wondering which time of day is it best to do the training? I do not go to a gym and cannot do pushups (just wall ones at present), which many heavy compound exercises involve, so have you any recommendations on what I can do regarding the training and when? So far I have had two days with 800 calories only and used a workout on youtube for one of the days, replacing one or two routines with just squats and low impact exercise with weights, etc.
    Also, I think I’ve eaten at the wrong time (7:30pm) so should I just start over and do one or two extra days to get it right?
    Thank you.

  5. i havc had an injury which stops me from walking properly my legs were smashed .i was 85 kg now im 110 kgs. i feel so fat and heavy can u help

  6. At the age of 36, I weighed 85kg, I was healthy and used to be able to walk for what seemed like hours and kilometres. I am now 45 and weighs a staggering 140kgs. In 10 years my life has turned into a complete nightmare to the point that I am so overweight that I have become a frighten recluse that never leaves home. I have trouble breathing when I walk especially up hills or stairs. I really avoid stairs they terrify me.

    So, how did this happen? MEDICATION… And the worst part I cannot stop taking these chemical handcuffs they call medicine because they will have an even more profound effect on my present health. I swear by the holy father… I really believe that pharmaceutical corporations make medicine keep people slaves to them like drug mules. Its all about the dollars nowadays. I know i probably won’t have long to live, but i still do 25 min on my treadmill and eat packages from dietary companies daily in a vain attempt to turn back the wheel of morbid weight horror…But it’s all about the dollars.

    I really wished i had made better decisions in the past because they now reflect profoundly harshly on my present.

    1. i think you are on to something w the pharm industry….in fact you are. there are cures for cancer. but what would happen to the gazunka billion dollar cancer industry?

      i’m on a lot of med too, i absolutely do not have a choice but I hope you well in a recovery to health. just ad to say

    1. no, god damn, answered this like 30x in the comments.

      Sorry I’m not mad at you. I just need to put it in Bold red comic book style, 50pt font in the post.

      1. Keith,

        Going to try this out. Can I recommend that you update your article to include answers to the questions that are asked on repeat? From what I see they are:

        1) Should I do cardio? If not, why not?
        2) What specifically should I eat? What is an example of a meal?
        3) How much water should I drink? And other than tea and coffee, is there anything else I can drink?
        4) In terms of processed foods, what is ok to include? Cheese? Yogurt? Crackers? Etc. Or should it only be whole foods?
        5) Is sleep important? If so, what do you recommend in terms of hours?
        6) Should I take a supplement? Or many?
        7) Why 800 calories? Why not 500 or 1000? Or…whatever number?
        8) What about time-of-day in terms of eating? Is eating after a certain hour banned?
        9) What are “heavy compound exercises” for the newbies?
        10) Why are you sharing all of this for free?

  7. Will you please just give me a good 800 calorie meal to eat and I will eat it. That way I will know I didn’t muck it up and I did everything correctly. I know I am being ridiculous and I apologize.

  8. I’m on the last 2 weeks of a competitive 12 week weight loss challenge ($750 cash prize for the winner) and am researching everything and anything to do with ‘rapid weight loss’. I don’t use a gym and refuse to join one for various reasons; could you please suggest some weight training exercises that I could do without the use of a gym? Any advice would be greatly appreciated. Thanks in advance

    P.S. I’ve lost 10% body weight in 10 weeks (approx 8.5kg) and am aiming for 20% total

  9. So my doctor has put me on an 800 calories diet a day. I have been on it for 3 weeks. I have not lost a single kilo. And have stuck to it and written a food diary every day. I am not doing any exercise at all because I am exhausted. I eat an egg in the morning, with ginger. Salad and protein at lunch, and same again for dinner. No grain. No dairy.

    What am I doing wrong?
