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. Hello, this article includes “if you do it correctly you can lose up to 15lbs”. Does this depend on your weight already? This is my day one, 700 cal. I am around 180lbs, and 5″6. I am hoping to lose approximately 15lbs, and then going a regular diet. Please respond

  2. First of all thanks Keith, this is great advice – and contrary to a lot of the scare story nonsense out there about extreme fasting. I live in the UK (don’t hold that against me) and I’ve done the famed ‘5:2 diet for just over 3 months now and, while not as extreme as the method you outline, it has worked – i’ve lost around 42 pounds. I’m working towards losing another 10 pounds, to take me to 193 overall (i’m 6’2″).and I’m going to try this to push me over the line! Cheers again.

  3. Hy Keith, im going to give it a try. Want to get rid of that last amount of belly fat, love handles and a little bit on the chest. Im 177cm 76kg. male
    My Question is , how is the balance of fat, carbs, protein? on my first day i got 783cal/14,47fat(eggs^^)/30,78carbs/131,87 prot. is that a good balance for this programm, or shoult i get rid of the eggs and lover carbs?
    Thank you for that programm, keep on rockin!
    (not a native sry 😉 )

  4. Starting this today. Female 5’2 177.5 lbs. Hoping I can lose 15lbs! Planning for a breakfast drink of coffee mixed with protein powder about 175 calories and then high protein dinner for the rest of the day’s calories. Wish me luck! 🙂

  5. Hey Keith was just wondering when the most effective time would be to have my daily meal, and before or after my workout, and what is your thought on carbs?

  6. Hi,

    I am on a five day low calorie diet with less than 800 calories. Мy question is if I lose a certain amount of weight and then, stop the diet and continue eating normally (by normally I mean not overeating, and watching what I eat) am I at risk of gaining even more weight than I have lost? I weigh about 160 pounds and I am 5.57 feet tall. Thanks.

  7. I’m 5’4 and have been stress eating and went from 125 to 160 pounds. About how much weight would I lose if I follow this plan?

  8. I am on day 6 of 7 and lost a couple pounds, then gained it all back, all during the week. Fortunately, it hasn’t been that many weeks since I’d had a body fat test and the cool thing is I gained 4.4 lbs of muscle, and lost 4.4 lbs of fat. So that is something to celebrate…However, I have to warn anyone thinking of doing this, that it’s pretty disgusting and not very much fun. I am normally vegan and a runner, but it’s next to impossible to do 100g of protein and 800 calories without resorting to animal products. I just don’t enjoy eating animal products though it was ok for a change, I am now totally grossed out after eating things like an entire container of 0% Fage or entire carton of eggwhites. Looking forward to this being over!

    1. no a lot of people here are looking for a quick fix. DON’T think of it like that.

      Look at this as a way “jump start” your results. Nothing more.

  9. I know the article says to weight train 2-3 times a week, but will it be okay if I weight train 5 days a week and cardio on one day? What will be more sufficient? Great article and I’m Starting this tomorrow!

  10. I did alternate day fasting in the beginning of februari which lasted in a week. Is it safe to start on this one now 4 weeks later?

  11. I’m finishing up day 4 of this — I lost 2 pounds a day the first three days — just about on track to lose my 15 pounds in 7. I borrowed someone’s “protein powder and coffee” idea (i do 1/3 scoop – about 50 cals) and drink that coffee later than usual — around 11:00 — so i can better hold my appetite until my meal. the brand i use isn’t very soluble so i had to mix vigorously and accept that there’d be a little powder floating on top after that.

    i eat my one meal at around 4:30 (grilled chicken salad with house dressing, can of tomato soup, and fruit) and savor it over about twenty minutes. i drink lots of water. i also have a few pickles lined up to satisfy cravings — didn’t need it yesterday or today (day 4).

    for the record i’m 5’4/170 (was 176 last Wednesday).

    exercise: i jog 4 miles a day (sorry it’s what i do — i’ll get the shakes without it) but pulled back my usual pace a TON — i’m basically jogging at a speedwalking clip. i’m also doing squats with bicep curls with heavy weights and planks one day on/one day off (days 1, 3, 5, 7).

    now that i’ve seen how little i can eat and still be fine if i’m conscientious i’m going to take advantage of this newfound moderation to be careful about meal choice and portions when i go up to 1200-1500 calories starting friday. this has been a great way to see what how little i need to eat in a given day, even if it isn’t sustainable. now a “normal” low-calorie diet will feel abundant

    thanks for the plan.
