270LBS eating 800-1000 calories per day.

Hope it works out for you.

When you're on the bigger side, it's not that bad. You have enough fat to cover that deficit.

This.
forget about the lbs themselves & focus on percentage of body weight lost.
Obese people can drop huge amounts of weight initially without ill affects.

OP after a few weeks (depends on the person) you will probably start to feel like crap.
If you want to eat that low do it correctly & look up PSMF from Lyle McDonald.
He outlines the proper way to do an ultra low cal diet.

My question is, is that all you're eating or is that what you're netting? B/c I net 882 yesterday but I ate a total of 1546 and I was so full that I couldnt take another bite of anything at any meal or snack. Listen to your body, if you're hungry eat, if not drink some water

NOT this^

Hunger is NOT a good indicator.... sorry. Also, look up "calorie dense" foods. There is a tendency to go for the lowest calorie, lowest fat, highest fiber .....so we end up eating a large volume of food (some of which is not nutrient dense). Look for low volume nutritious foods (healthy fats) ..... to up your calories.

Eat more. You're going to be losing lean body mass and although you might feel fine now but that won't last long. You should try scooby's calculator and start eating at LEAST your BMR.

I started January 2nd at 272 lbs and set a goal of 2,000 per day but tried at first to stay closer to 1,500. I kept close track and wasn't exercising. I have lost about 35 lbs and am now doing 2,000 per day, still keeping track, but go over my 2,000 alot. I think obviously under 1,000 is not enough. Maybe for a few weeks it's ok. I just know I'd have been unsatisfied and feeling deprived if I'd have tried that. Slow and steady wins the race, as the tortoise once said.

One thing that is common when you try to lose weight the first time, or if you try again after a while, is that the first 10-15 lbs will drop off quick. This is normally associated with water weight and is not a good indicator of actual fat loss. Look at any fad diet plan or pill, "We guarantee you will lose at least 10 lbs in the first 30 days or your money back!" Of course they can make this claim, because once you decide to make changes in your diet and exercise, this is a common amount that is lost. The bigger you are, the more you will lose.

Now, having said all that, I will say this, if your goal is to go low calorie for a short period of time, then fine, but understand that this is not a long term solution and will, in the end, do more harm than good. Food is fuel, and you need fuel for everyday things. If you've increased your activities, you need more fuel, not less. The goal is to eat less than you have before, but still eat enough to allow your body to function the way it's designed to function. Food is for energy, hormones, growth, mood, focus, and general overall well being. It's not evil, its a requirement for living.

I don't know what your overall goals are, nor do I understand why you're eating so little right now and why 3-4 weeks of eating this way is important to you, but I would suggest that you do some research into what is a healthy way to lose weight, and I would also suggest to expect this to take a while, be patient, and try to find a way to make weight loss "enjoyable." It's possible, believe me.

Wave bye-bye to your muscles.

Exactly what I was thinking :sad:

Me too. And your libido.

Hope you weren't planning on keeping muscle or hair. Just think though, you'll have some money saved up to help get you through the start of those medical bills from all the health issues you'll have in the future. :flowerforyou:

Jesus... scare tactic much? You really think he's going to do that much damage in just a few weeks?

If you're asking, clearly you have some question as to the benefit of this for any period of time.

Don't ask us...ask your doctor. Seriously.
