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. IF I eat 800 c a day, How Long should i do cardio; How long should i do weight lifting a day. Also how much protein should i drink? Does it matter where those 800 calories are coming from? Burger etc; I’m a 30 yr old Woman. 5/6 220 lbs. Ive been jogging a couple weeks now.

      1. I’m on day 5. I guess I don’t have much of an appetite since my fiancee left me. So I am using it to my advantage. Pumped iron 5 days straight. My pants aRe falling down. I haven’t checked the scale, but I think this plan works excellent.

      2. Agreed with Ken; I had to laugh, she obviously does not comprehend what she reads…. I wish her the all the best! Maricella, hire a Trainer, it will be worth every cent!

    1. Did you even read the article???? All of your questions were literally answered. Someone with your IQ should probs not try this diet lolzzz. Stick to the gym

  2. Hey I was doing this diet already I’ve been doing it only for like four days and already lost like 4 pounds but you say to only have one meal and I actually get lots of healthy meals in at less than 800 calories throughout my day in the morning I have a green tea no sugar and a large apple then I take a granola bar that has about 100 calories then for lunch a turkey 6 inch sandwich from subway like 280 calories then for dinner some veggies with zero calorie dressing or some baked chicken with broccoli and I stay pretty full throughout my day I also drink about 4 bottles of water every day my question is do you think I can keep doing this for maybe a month? Since I stay full and eating healthy I’m a 26 year old female 5’4 and I weigh about 172 pounds. ..

    1. i say one meal is typically easiest since you don’t spread your cals so thin across so many meals. NO NO NO NO NO, DONT DO THIS FOR A MONTH!!!!

  3. I actually think steak/lean beef is a pretty good meal, for this plan. Accompany with some vegetables (I luv pumpkin), boom, nutrients and great amount of protein.

  4. “Starving” always works. How many articles do we read of people who get stuck in places for days and months w/o food, and when they’re found, they look fine if they weren’t skinny before! Besides,. I lost a 100 pounds eating 500cals a day, never felt better during that stage, kept it off for a year in a half until I went to college and went ape on food again. I’ll just repeat it since I wanna look back good in a bikini. Point is ALL commercial diets are scams, ALL commercial diets just like to make money off of people who are unknowing of their deceit. Merrr.

    1. No, “starving” doesn’t always work. If someone already has metabolic damage, eating fewer calories is only going to hurt them further.

  5. I’m depressed. Can I just stop eating forever and end the pain in my head from reading some of these posts written by the dumbest people I’ve ever heard of?
    You can use the internet to tweet on Twitter and troll Facebook but you can’t be bothered to research the proper fuel for the only body that you will ever have?
    OK I shouldn’t be so unkind, but really, when did people stop thinking before they wrote something?
    The human race is doomed.

  6. If I were to do 800 net calories a day instead and add cardio, would I get the same effect? (I jog regularly and don’t want to stop for the week if I can avoid it)

  7. I’m 18..my height is 5.6inchs..and my weight is 167lbs..
    I will do daily elliptical machine for 15mins..and some workouts for an half hour…I want to lose 10lbs…is this possible by following this diet plan?

    1. you will lose a few pounds of fat but remember most will be water weight. Don’t get too emotional with the scale.

  8. Is it fine to do this diet if i am only 16? I really need to lose some pounds for upcoming party.
    What if my proteins for the day are only 50+ grams?

  9. Can u explain the correlation between eating low calorie for a long time then binging and gaining weight again?

    1. Well a lot of women eat very low cal and do a lot of cardio in hopes of losing weight. They deprive themselves well beyond any reasonable amount and in turn end up binging once they reach their goal weight.

  10. What will cause metabolic damage? Could u pls give me example?
    My friend did a diet that consists only about 1000cals everday for months and now she is super skinny i want to be like her.
    Fyi i am so short under 5’2 so maybe my calorie intake should be very small? Thx

    1. when you constantly lower calories, increase cardio, or both in an attempt to lose weight to the point you can’t lose weight any more on even the lowest of calorie diets because you fucked your metabolism and thyroid so badly. This is typically followed by a large rebound in weight gain once you reach your goal weight that won’t come off even when you try a cal deficit again.
