No. What will happen is that your body will try to stay alive. You will sleep more, move less, have no energy to exercise. Your body will do its best to reduce the calorie deficit and weight loss will go down. Why not take it slower, be full of energy, keep your hair andnot kill anyone that can be or not be part of your family.

Everyone is different. If it works for you, then do it! Just be aware of the consequences. For me, I always eat under 1000 calories. That gives me a good 300 calorie deficit everyday. :)

Are you in a coma?

I wouldn't advise it unless you're going to be very careful of what those 1000 are. And even then I would only do it for a very few days and then go up to about 1600 for a day. But be careful not to go into starvation mode. 1000 calories of lean meat, veggies and some fruit along with lots of water are of course not the same as a big piece of chocolate cake and a malt. But I'm sure you already know that.

Unless you're exceptionally short (and I mean under 4'5") and really tiny... 1,000/day will not sustain you nor will the weight loss last.

Our bodies are made to go into starvation mode when we do not receive enough energy/calories. I know it sounds counterintuitive, but if you eat more (your BMR) then your body will have the energy to shed weight and allow you to work out longer and harder. I've gotten out of my plateau by increasing from 1350 to 1650, and I'm 5'0".

Unless you are 4'6" and in a coma, your deficit is more like 1000 calories a day.

Iv seen people lose on it when they have proper nutrition i mean you needs lots of protein but
on a 1000 its hard to get it .... like everything you need. I personally wouldn't want to go on a 1000 calorie diet .

Yeah, you will lose weight, but eventually you will stop losing weight and hit a plateau and have to increase your caloric intake for awhile before you begin to lose again. I had mine set at the 1200 calorie intake for the longest time, and lost rapidly, but then stopped for 3 months, and I was miserable. Now I'm eating around what my BMR is (1600 calories) and I feel so much better! And after plateauing for 3 months, I've finally lost 8 more lbs. Its not worth it in the long term, it is better to lose the weight slower anyways, you have a better chance of keeping it off that way!

Rather than focus on staying under 1000-- if your main focus is to cut weight fast, how about sticking to ONLY whole raw veggies, maybe a minimal amount of fruit, and lean meats. Honestly if you stick to those guidelines you will shed weight in the quickest way possible, and wouldn't even have to count calories

There's a lot of people on this site who will tell you if you're eating under 1200 calories a day your body will go into starvation mode and not lose any weight at all. That's not true; people on medically supervised diets and people with EDs lose weight that way all the time, often quickly. However, you will have an extremely difficult time getting adequate nutrition, and it will be very likely that when you won't be able to sustain the weight loss once you reach your goal and increase your calories. Aim to lose 1-2 lbs a week and you'll be healthier and have more success in the long run.

Eat more, lose more slowly. It has a much better chance of staying off and I bet you'll feel better overall, too. Slow and steady wins the race.

You're a guy??? How tall are you? I can't imagine any man being able to sustain his muscle mass or body on 1000 calories per day.

Edit: However, if you are morbidly obese or have a very high percentage of fat, then in theory it could be possibly although you probable will still burn up a lot of muscle mass in the process of going that low calorie.

You joined here with a goal to lose 15 pounds, lost 25 and want to keep losing at a very ambitious rate. That's concerning.

If you constantly eat 1000 calories a day you will lose weight but once you start eating normally you will gain it all back, It is best to figure out your TDEE and subtract about 20% of that I used this calculator: http://www.fitnessfrog.com/calculators/calorie-calculator.html and it works really well

I really think you should talk to a Doctor or a Nutritionist!
If you don't put fuel in your body!
Your body suffers and the weight loss may be dramatic but it can damage your organs..
Please be carefull..

What's the rush?

Crash dieting results in rapid weight loss, a significant portion of which is lean muscle mass. It also, frequently, leads to your weight going up and down like a yo-yo as you're not retraining your brain to eat healthy portions.

There's more to good health than a number on the scale.

You'll probably be hungry!

I wouldn't be able to get the micros I wanted in? Probably too tired to get out of bed too. I'm not you, though.

Open your diary so we can all tell you how terribly you eat!!

umm OP what happens when you plateau at 1000 calories a day? would you drop to 750? that's nuts yo.

anyway i know if i only 1000 calories on a consistent basis i wouldnt have the energy to get through my workouts and i'd be b*tchy as hell. also based on how i've seen other people who do that low calorie i'd probably also be cold all the ime and muy hair would start falling out.

Here's a thought...instead of asking all of us, and getting 10 different answers, why don't you give it a try for a week and come back here and tell US what happens, so that we know for the next person who asks this same question...just a thought.

Yep, this^.

I can't imagine getting all of the essential, important, health-sustaining nutrients I needed in only 1000 calories. But, with some effort, and some very careful supplementation, I suppose it could be done. I hope you're willing to ensure those basic nutrition needs are met if you pursue this path.

Ask yourself if your health is more important to you than your weight loss. What's the hurry?


Taking care of yourself is worth all of the time and effort.

If its for a short period of time I don't see anything wrong with it. :) however it might be better to juggle between 1000 calorie days and 1200 calories days... From my experience, i used to be 66kg... And I dropped down to 50 over a 6 month period. (mind you I wasn't in the healthiest of mindsets... My parents and friends were suspicious of me becoming anorexic) I used to only eat breakfast (handful of cereal grains, pear and a blob of yogurt) I always skipped lunch maybe ate a meuslie bar to keep me going and I ate dinner only about 2 or 3 times a week because most nights I was working (waitressing).

At first, the weight just fell off. And I got more and more motivate to keep this habit of eating the more I lost. I was jogging for 8km most days too and some days I tried to jog twice. I had such high motivation because I could instantly see the results, however it didn't take long before my body went into some sort of slump. I was falling asleep at uni all the time, couldn't concentrate on my studies at all but still had enough eneregy to work. And I still forced myself to run everyday. HOWEVER, once I reached the weight of just 50kg, my boyfriend started making me eat more because he couldn't stand taking me out and I'm not eating.

Anyway, the point of this is.... If you eat only 1000 calories a day or less.... Yes the weight will drop - especially if you do heaps of cardio. BUT, your body will adapt over time to eating this amount. Therefore even after you have reached your goal weight... It's not as easy as you think to just go back eating a normal diet. You'll gain weight like crazy because your body suddenly doesn't know what to do with all this extra energy. it adapted to only consuming 1000 or so calories a day and is cabaple of drawing out all the energy it needs from those calories.

I gained 7kg over a month from going back to eating a normal balanced 3 meals a day diet. (although I stopped exercising during this time also... I was traveling in Korea at this time)

So tread lightly on this one because your body WILL ADAPT. Juggling 1000 ~ 1200 might be a better approach :) and keep with cardio!! It's your best friend in weight loss. :)
