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. Oh another question..
    I read that sake and vodka have the lowest calories ( and gluten free alcohol) If you like to drink.
    Since it’s the weekend, I had 3 shots of vodka and one shot of sake .
    . will that ruin my diet ?
    Should I totally stop drinking?
    🙁

  2. first of all i appreciate your effort for uploading this helpful post. i want some of your help I am 20 . 6 ft height. weight 83 kg.
    I am lean just like athletic. but from the last year I got some fat around my waist. fat is only around the tummy. I want to burn this. will it be helpful?

      1. Ok… i was thinking ooo ill do both cardio and weights but then I read “dumb ass radar” along with the death threat so im laughing out of fear and how hilarious you are… ok so no p90x during this week is that right? Weights ONLY?! (I know! But I still feel like I gotta ask)

        1. I was CRACKING up at that too , i feel so off not doing my treadmill this morning like normal but i wanna really try this out so no dumbass radar alerts from me ,

          I was wondering can i do strength workouts more then only 2-3 times during the week ? how about daily ?

  3. I am 18, 5ft5 and 126lbs. Its now monday and i want to lose weight by friday. If i start this diet tomorrow how much weight will i lose by friday???????????????????

  4. Thanks so much for the info!! Finally a real answer and not the typical, your body will go into starvation mode… overnight. Lol

  5. Ho! I’m 21 years old and weight 140lbs I have a 2 year old son and before having him I weighed 113. I would like to get down to 120 atleast.. how much do you think I’ll lose in a week if I do this?

  6. My plan is 30 minutes of weight training in the morning, 30 minutes of jogging at night. I’m calibrating my macros to 40% proteins, 40% fats, 20% carbs. Drinking close to a gallon and 1/2 water. 1 day off from the weights. I know you strongly advise absolutely no cardiovascular training because of the study but they didn’t have a 3rd group tested with a similar plan such as mine. I’m 5’10, was 220+ two weeks ago. Now I’m 200 pounds I’m aware I will loose some muscle mass but my goal is to continue a 1 pound loss a week until the bricks on my stomach return. Will my plan work?

  7. I am going on vacation in 3 weeks and I really want to lose weight and lean out. I am 5’4 and weigh 165 pounds. My goal is 130. Is this possible in 3 weeks?

  8. I am 49 5’2″ 148#. I started to count my caleries and realise I am not eating enough in a day. On a regular day I eat/drink 600 to 775 calories a day. Will this diet work for me if I raise my calories to 800 and lift weights? Or how do I get my matabilism to change to burn fat?

    1. 600 is way too little. Stop doing that right now! You should bump them up to 1700 for a bit to restore your metabolism.

  9. I have one week and want to lose 10 lbs, I have a very sedentary job so I do well not being hungry, and don’t even notice as long as I eat one meal a day, but then when I get to the gym I shake and feel like I have low blood sugar bc I know my body wants more energy. Any tips? Also, less reps with more weight?

  10. hi, im 29 female standing at 5″2 and a half, lol ive been waiting to grow another half inch since I was 11! Anyway my weight is currently 172 can I drop to 160/155 in a week on your plan Im not trying to get super thin I love my curves “booty” just want a flatter tummy and toned arms. Currently doing 4mins of Brandon Carter “BBC” HITT on youtube
    once in the morning and then again before bed is this ok? Thank you for your time in advance….

    1. You will lose a lot of water weight with this plan. I recommend people to lift weights since that’s going to help you maintain muscle most efficiently.

  11. I’m a distance runner but also do a fair amount of lifting as well. I’ve been training for a few months, but am out of running for three weeks with some lower back issues. At 5’8″ and 135lbs, I was thinking this might be the perfect time to lose some extra weight – since I know I can’t do any sort of diet while running 60 mile weeks. Or is doing this for one week going to make it difficult once I start running again?

  12. Hey.. I am trying this diet plan currently. But the problem is that I don’t have a gym membership, neither do I have weights at home, can I just try some floor exercises at home? Also, Is it possible to lose weight by just being on diet and with no exercise?

      1. It has been a week now.. but I have not lost a single kg. As you say, I havent lost any muscle nor fat. Why is that so?

  13. I’m supposed to ship out for basic training in a week, but I’m 12 pounds over. Would this help me get down to weight? Military standards are ridiculous being a short girl..

    1. I can’t and won’t guarantee anything. You’ll definitely lose weight, but I can’t tell you exactly how much.

        1. you can go outside and play or get into a sport, and just try to eat healthy foods. Your young, there is no need for you to be counting calories. Talk to your parents about it they should stock up on healthy foods in the house and start making healthy dinners.
