how much weight can you lose in a week without eating

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.


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.
  • 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 muslc.e

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 the answer to “How much weight can you lose in a week?”

Take it to the next level with the Xtreme Fat Loss Diet

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

And the answer is no.

The way I laid out the diet above at 800 calories, you can’t do it for more than 7 days.

But there is a more strategic approach you can take where you can go and lose a ridiculous amount of fat in 25 days or less.

The program is called the Xtreme Fat Loss Diet, created by fat loss experts Dan Long and Shaun Hadsall. It’s essentially a much more fleshed out version of the plan I laid out above that will allow you to lose MASSIVE amounts of fat and get as lean as possible in just 25 days. Plus the program incorporates cheat meals so you still get to eat your favorite foods.

Questions? Like steak? Let me know down below.

    Keith - January 21, 2017

    I would do some type of resistance training if possible.

Brian - January 20, 2017

This article had me laughing so hard. Especially this part, “…and if you even step foot on a treadmill, my dumbass radar will go off and I may have to kill you.”

Hi I’m new to dieting I’ve been eating less than 1,500 calories a day for a week and I’ve only lost 1 pound , I want to try this 800 calories a day for a week but I’m not really sure what to eat like I said I’m new to this please help , thank you!

I have decided to go 10 days on 20 cals a day the 20 cals are from 0 sugar cola. Before I had to have my female reproduction system removed due to ovarian cancer I weighed 8 stone 3 pounds. That operation cured the cancer +plus a lot of chemo and steroids. But I felt so healthy and active at that weight my hight is 5ft 7in. Now I weigh an awful 16 stone 1lb and feel awful due to this huge weight gain. I only eat once a day (always have done since I was about 17 yrs old)I’m totally fed up with diets that make me gain weight!!I plan on drinking 4 litres of diet cola a day with glucose free hydration salts added to 1 or 2 drinks. I am not very active due to my weight which is also the cause of my knee and joint pain. But hope to start to become more active with the more weight I lose.

    Keith - January 7, 2017

    Whoa, 20 calories? I don’t recommend that. I’m unfamiliar with your cancer but 20 calories per day is never a good idea.

    Angie - January 14, 2017

    …diet soda is bad for you. 20 calories a day is called an eating disorder. Sorry for being so blunt but please educate yourself in healthy weight loss… Also, seeing as you are a cancer survivor which is awesome by the way, you really don’t want to do this to your body. Cancer can cause weight gain unfortunately, due to inactivity while taking treatment. Most people think it’s the opposite but it’s not! Your body needs nutrients, especially if u want to remain cancer free. If what you seek is merely to lose a few pounds and be healthy then you should be eating a healthy diet full of protein and vegetables and limited carbs. Weight train… lift those weights girl!! If you weight train 3 times a week…eating a normal healthy diet.. your body will grow muscle which means your body will burn more energy while your at rest which means the lbs of fat will fall right off of you. Also.. your metabolism slows down when u don’t eat often.. eat 4-6 smaller meals a day… get that metabolism pumping. You will be successful but please do it with your health in mind. You might shred some fat and muscle on your 20 cal 10 days.. but as soon as you stop all that weight u lose in 10 days might actually double. It’s unwise.

    diet coke = weight gain
    it has been proven and backed up that diet coke does actually cause weight gain. only have in moderation.
    i survive on 300-400 calories a day. sometimes even fast (o calorie days) and i find the trick to losing weight is eat healthy!!!! so vegetables, protein, fruit. NO CARBS! NO SUGAR! and have as little dairy as possible. have smaller portions, and you can easily shrink your stomach down.
    You know what they say, abs are made in the kitchen.

thnks alot for this amazing thing

Grant - January 4, 2017

Is this fasting? will the body fat return the day you start eating normaly again? Also, what are the conciquences of doing this below the age of 16?

    Aj - January 6, 2017

    Fam i do this and dont start all of a sudden you should wait for a week long break to get used to it at home or your going to suffer. Drink plenty of water and honestly he sounds dumb. Heavy doesnt mean good doesnt have to be heavy weights just build up to it. And personally fasting not good. I do breakfast and dinner 400+400 keeps ur pretty good same age btw

      Linda - January 16, 2017

      I think that’s the approach I’ll take 400 for breakfast and 400 for dinner .. I need to lose weight so I don’t have to go on insulin.. I’m really hoping this works for me .. my problem is gonna be giving up the Diet Pepsi.. but I’m gonna do it ..

Mandy - January 4, 2017

Love handles and tummy. Will they go too

    Keith - January 4, 2017

    You can’t spot reduce fat in those areas, but yes, over time you will lose fat all over your body.

Mendes - January 4, 2017

How much would I lose on an 800 calorie diet for a week?

    Keith - January 4, 2017

    Depends a lot of on your starting weight. The heavier you are, the more weight you will lose.

Wendy - January 3, 2017

I’m a beginner at weight lifting. Can you suggest a website that I can review to help me with doing at home verses a gym?
Thank you Keith!

Grant - January 2, 2017

Is it ok if I do cardio, since I dont really care about muscle gain?

Terry - December 30, 2016

Shoud i put sugar in the coffee or drink it black

Wade - December 26, 2016

Let’s say a teenager wanted to lose some weight. How much would be healthy to lose a week? And if you could, would you recommend a diet?

    Keith - December 27, 2016

    Everyone, especially teenagers should focus more on establishing healthy habits instead of aiming for quick fixes.

Joanne - December 26, 2016

I have eaten 600 calories a day for 8 weeks now. I jave hated it and have only lost 20 pds. I’m 51 and have a disintegrated disc in my back so can’t do much exercise. Saying you can lose 25 pds in 1 week is bullshit!

    Nikole - January 16, 2017

    To the lady who said BS…. Weight building exercises are essential part of this weight loss. 600 calories a day without making sure it is high protein … almost no carbs and weight training is going to send your body into starvation mode and you won’t lose much fat. Our bodies are designed to live even when we have very little food. That auto mode kicks in at this point.

Sarah - December 24, 2016

Probably good to note if attempting this plan to make sure you are taking a good multi vitamin as well.
