Eating 500 calories and BMR .

You seem like your not going to heed the advice of posters that have had success so this is probably pointless but I will try anyway. I weighed 560 lbs. 33 months ago and could barely walk. I started working with a dietician and my doctor and from the beginning even though I had over 300 lbs. to lose under doctors orders I was instructed to lose 1 to 2 lbs. a week for sustainable weightloss. So we adjusted my intake over the course of 3 weeks to maintain that weightloss. Fast forward 33 months and 303 lbs. down my current BMR is 2160 with a 500 calories deficit built in to lose 1 pound a week but because I burn 1000 calories most days in exercise I eat 3000 calories a day and am still losing weight... By taking it off at a recommended pace I haven't sacrificed to much muscle which is good because having more muscle burns more calories.... Speed isn't the way to permanent weightloss and I wish you would reconsider, if not Good Luck to you.....

For all those doing my numbers thanks by the way this is what I started out at
284.4
Bmi 40.8
BMR 2048
Fat% 51.2

Three weeks later today in fact
269.51
Bmi 39.8
BMR 2017
Fat % 49.8

And I do light weight 40 pounds upper body and 55 pounds lower body 5 days a week alternating between the two

Maybe this will help

3 weeks ago
284.4*48.8% = 138.8 pounds of lean body mass.
today
269.5*50.2% = 135.3 pounds of lean body mass.

So out of those 15 lbs you lost, 3.5 of them were of NOT FAT. As you continue this VLCD, the proportion of NOT FAT lost will increase.

Added: If you lost weight at the same ratio of fat/not fat as you are now (which as I said will increase as you lose fat), when you hit your goal weight of 155 you'd have a lean body mass of 108.6, which would give you a body fat % of 30% even though you'd be square in the middle of normal BMI range.

Man these numbers are confusing

Eating very low cal diets especially when you start off as obese has been linked to gallbladder stones. If you havent had your gallbladder out yet that may well be something you can look forward to after following a low cal diet plan.

Even if you don't listen to anyone else- listen to this guy! The proof is in the pics

Listen to your doctor and nutritionist and forget the rest of us.

If you are interested in eating more, tell them that. They can help you create a diet where you can eat more and still lose weight. At your starting weight, you should still lose more than 1 lb a week for a while to quite a while, even with a higher calorie intake.

Did he tell you how long your 1000 calorie diet will last?

KilikiMom

here is an idea...QUIT FOCUSING ON THE NUMBERS.....you need to focus on getting healthy...cause what you are doing is quite the opposite of getting healthy....please listen to everyone (and may i suggest you find a new dr if indeed this dr told you this was okay to do...because any dr who says that eating a net of 500 calories a day is a GOOD idea...is a horrible dr who needs to have their license revoked for life!!!! all he.she is doing is harming you and a dr should not put on in harms way just something to think about...but honestly i think you just said that to try to justify eating 500 calories a day i dont think a dr would be okay with that they'd probably rip you a new one if they read what you are doing to your body) you are STARVING YOURSELF....and my concern is eventually you will quit eating all together and become anorexic you are well on your way to that stage you need to stop and re-evaluate what you are doing to yourself....

Ok so now I m a liar , really? No I this is what is happening in my life, and the numbers that' is something I'm interested in so yes i would like to know more. The 500 cal diet should last no more than three months apparently this starvation mode dosent occur for us larger people for quite a while then the calories will gradually be increased
Thanks for all the personal messages and calculations they are greatly appreciated.

Some simple science backed up with numbers.

At less than ~1200 net calories a day, your body will go into starvation mode. Your body thinks it is in a famine and you are starving. Bodily processes will start slowing down to conserve energy. Metabolism drops by approximately 40%. That's the important part. Let's see what this means.

Your BMR is approximately 2000. Probably a bit higher, but let's go with the lowest reasonable number. That means that your body burns about 2000 calories just by existing.

You're in starvation mode. Your metabolism is down by 40%. Before, you were burning 2000 calories just by existing. Now, you're only burning 60% of that due to the 40% drop in metabolism. Your body is burning 1200 calories instead of the 2000 it should be.

This means you can eat 800 more calories a day and lose weight at exactly the same rate. That's a lot of room for proper nutrition.

According to what you posted before (and according to my calculations before) you've already lost 3.5lbs of non-fat while you lost 11.5 lbs of fat. So yeah, your body is already chewing up muscle at a rate of knots, even as a larger person.

This I think is the answer I have been looking for ..... Thank you

So two dozen people give the same answer--that you will lose more weight (and keep it off) long term by eating more than 500 calories net, but only one of them is the answer you were looking for?

You claim you need to lose weight fast for health reasons, yet what you are doing is far less healthy than staying fat. Honestly, if you're going to keep eating 500 calories/day net, it would be healthier to remain at 269 pounds, eat good healthy food and get more exercise. REALLY it would.

Meh.
