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. see it depends on your current body weight. you can loose good amount of weight without losing muscles.
    just let me know your weight , hight, age & sex.

  2. Hi there. In 15 days I’m attending a life changing event. I used to have a sedentary lifestyle due to my work. Now I’m around 155 pounds, 5’8″ height 22 yrs old female. And I’m vegetarian. I started doing cardio every day at home 20 30 mins, I walk for 50 mins about 20 mins per mile, I try to be more active but I’m afraid i won’t manage to lose fat fast..any advice please? Oh and I don’t eat any sugar salt and carbs such as bread and pasta, little starch. I do get enough protein.. Maybe I need more workout? Need help(

    1. Stop trying to look for shortcuts and trying to lose weight “fast.”

      This plan is just a little “jump start.”

      It’s not magic, and it weight loss, magic doesn’t exist.

  3. I’m 5’7 and weight 185 and hope to drop down to at least 150. I’m 17 years old and I’m going to get like 800 calories a day. Also I plan on running 5 miles outside every day and plan on doing at least 50 chin up every day and 200 push-ups. Would I still only be losing 15 pounds in a week or would I lose less or more than that? I plan on doing this for only a week.

  4. So if I don’t care about losing muscle, can I do cardio instead of weight training? If I follow the plan exactly will I still lose the same amount of weight but doing cardio instead ?

  5. I’m participating in a 6 week 20 lb challenge. I’m down to my last week but I have 6 pounds to loose. The camp challenge has put me on a “Talapia & Asparagus Diet” (3 times a day @ 500 calories per day) with medium to heavy cardio (50 mins. a day for the next 6 days) to melt away the pounds. Do you think I can accomplish my weight lose goal by 10/26/15?

  6. first and foremost we all have to understand that we have not gained our weight in one week or one month. so how even u think to melt all of your excess weight within one week or one month span of time.
    yes but on another part you can start loosing weight from day 1. its all depends on experience and expertise of your trainer , your god father in your weight loss mission.

  8. There are 12 days left in our contest at work (10 ppl will win $1K each). I am 49, 5’4″, 183# and have lost 53# sensibly in the last year (food changes, exercise, etc) but now I have no winter clothes so I must be in the top 10! Is it possible for me?

  9. Hello, a friend is half way through her week and already lost 4lbs. I have a lot of weight to lose and wonder what your thoughts are if I asked would it be safe to do this once a month?

    Thanking you in advance

    Rachel

  10. Actually the contest is inconsequential… I’m just wondering how much I can expect to lose in a week taking into consideration my age etc.

  11. How often CAN you do this? Like if you finish your week, can you wait a few months and do it again? How often specifically?

  12. i have already mentioned several times dont focus on 1 week programme if you are really serious about your health just plan for long term fitness schedule. 15 min walk / trade mill, 25 min free exercises . remove alcohol , sugar , deep fried & red meet from your diet. no salt in evening meal. you will see a great changes in your body within couple of days.
