Honest questions: How are you judging that she's at or over 300lbs? And a very mean one... can't she just go back to starving herself? Or with TPN is it literally impossible?
1) I just picked a number that sounded fat, but not Amberlynn fat.
2) To elaborate on what the poster above said: TPN is calculated to the patient's daily caloric needs. In someone who is at a healthy weight this means they get enough calories to maintain that weight. The problem is when you're fat, the calculations get fucky. If you use their current weight to calculate how many calories they need, you're feeding them too much. If you calculate it on what they should weigh, there's too few calories. The current school of thought is that lower calorie, higher protein formulations are best for obese patients because losing weight (but not totally starving) reduces the strain on the body.
Assuming her doctor isn't a total HAES-tard and that s/he calculated based on Kat's ideal weight and not what she currently weighs, Kat would lose weight pretty rapidly by default if she really can't eat like she claims. She wouldn't be getting enough nutrition to maintain her size. If she stopped eating
and did her physical therapy exercises instead of sat around in her chair on the internet all day? She'd get down to human proportions pretty damn quick.
But Kat can and does eat on top of TPN and we know this for several reasons. The big one is because in the two years she's been on it, she's absolutely ballooned. Even if she was calculated based on her current weight, she wouldn't gain unless she ate food on top of that, because the TPN would only be enough to
maintain her current size, not add to it. But also, because she's just really really shitty at hiding that she eats. Ignore the daily coffee selfies and occasional hot chocolate or soda because 150-200 extra calories a day isn't really going to make her explode in such a short frame of time like she has. Instead, look at the background of her kitchen selfies: she lives alone yet there's always bread, bagels, ramen, crackers, cereal, etc. in her apartment. IDK about anyone else but if I straight up couldn't eat and no one else lived here, I'd throw out every morsel of food in my house so that it wasn't there taunting me. So she's eating and not purging (at least not purging well; she has previously posted about "draining" through her g-port) if she's not only maintaining her weight but gaining rapidly on top of that.
She claims it's her "fibromyalgia meds" that made her gain weight. Assuming she means something like prednisone, the reason pred makes you gain is because you get hangry all the time and overeat. (This happens in animals, too, btw. If anyone's ever had the pitiful misfortune of a dog that needs to be on pred for a while you know they beg for food 'round the clock because they're hungry all the time and don't understand why you aren't fixing this situation.) So even if they're pumping her full of steroids, she wouldn't gain weight if she just stopped fucking eating on top of her TPN.

In other news our fave tubby has lost some weight!
Yeah... good luck with achieving your goal weight when you’ve just got TPN again.
Lol didn't see this caption. I thought it was just going to say "morning coffee" like usual.
The bag behind her is a Weis 2 Go bag. Weis is a supermarket chain, so that's grocery deliveries. Of course, it could be toilet paper or something. However on her "I just got home" selfie there were several of these bags on her counter so I'm gonna guess there was some actual groceries involved.
Here's a pic from March. I guess she looks like she lost some weight? Her double chin isn't as prominently squishy. Hard to tell when she's wearing that giant hoodie.

Also from March, looks the same size as now to me. Could be just a more flattering photo but.. IDK I just don't see it. 42 pounds is a lot of weight for someone who isn't a deathfat.
