A lb of fat is 3500 kcal, you need to have a deficit of that to lose a pound. I call total bs on that. I can eat several months of under a thousand calories and barely lose a pound a week. If I eat 800 cals of crap, I gain. 800 cals of disgusting protein, well there is the winner. I see the same stories all over this website. It's what you eat, not the calorie content of it

When you get a chance you should research starvation mode. It is very interesting actually. Our bodies were designed to hold on to as much fat as possible when it feels as though you are going through a famine. It will eventually lose the battle but at a cost. It is imperitive that were are getting enough protein in our diet daily or it will start converting your muscle to glucose in order for proper brain function. We are amazing mechanisms. I feel your pain though.

I was painfully aware of starvation mode, so much so I physically forced myself 1000 calories a day just 4 days after surgery. I didn't want to teach my body it was ok to hang onto the fat

Wait, what?? 150,000 calories? Dudette, your math is off. She simply needs to eat as much as she burns. She does NOT burn 150,000 a day.

WHAT!?!?!? ACK! I couldn't eat 1000 calories for at least 6 months. Be careful.

Yeah where are you getting this math that to maintain 600 pounds she has to eat 150,000? She's bed-bound, does zero activity. I imagine she could easily maintain her weight on less that 15,000 calories, which is certainly doable, even post sleeve if you drink your calories, eat and drink at the same time, and eat slider foods.

Sorry, 15000

Sorry, 15000

Definitely doable post-sleeve. See above.

I can guarantee you she doesn't burn 15,000 a day either.

The doctor always chews them out that they are eating 15000 cal just to maintain. I'm not saying these ladies are eating salads, I just can't wrap my head around the fact that they are eating the same huge portions. The same activity, yes. Body is hanging on to the fat.

I am a lot taller than you, 1000 cals is nothing now, I really try to keep it under 1200 though

Her BMR is only around 3500 calls even at that weight.

Here is a very unscientific general calculator. http://nutritiondata.self.com/tools/calories-burned

If Penny is 625 pounds, 5"5", 45 and sedentary, she would only burn ABOUT 4300 calories a day.

Does anybody remember a few decades ago the conventional wisdom about fat cells? Once added by weight gain, they never go away? Even with dramatic weight loss, those shriveled up fat cells remain in the body just waiting to pounce on calories and plump themselves up again?

That mental image has never left me. It makes me so mad that these skinny shriveled cells are just lying in wait. I think it was actually what the liposuction industry used to convince us that lipo was a way to solve that. Actually remove the skinny shriveled fat cells along with plump fat cells once and for all.

Not saying it's true. Just saying it stuck with me.

Kinda like these fat cells.

That's an interesting calculator, wonder how accurate it is. But even 4k, would still be hard. She had gastric bypass, which you also have to factor in the limited absorbtion. Someone should put a 24hr cam on her... See what she eats... 4science

Yup. I blame my mother for fattening me up as a baby.

Oh I agree with the fat cell theory, the last place I gained weight as a kid was my arms, when I lost for a short time it went away, but the very first place it came back was my fat a$$ arms. Easier to store fat in an existing fat cell than make a new one
