Starvation mode does exist, but it's a medical term that the fats have completely misunderstood! The starvation mode they talk about really doesn't exist but the medical kind does and it's incredibly fucking dangerous!! I have a paralysed digestive system and although I have a feeding tube through my abdomen and into my small intestine, I am physically incapable of absorbing enough calories or nutrients. My metabolism has slowed and my body does try very hard to hold on to every calorie I manage to absorb but guess what it can't do??? ... Make me gain weight while living with a calorie defecit!! I am still losing weight! Sure, the loss has slowed down as my body fights to hold on to everything I manage to take in, but it hasn't stopped and I certainly haven't started gaining!! Plus, if they actually were starving then those times they "eat a bit of the junk food Mom bought" could literally kill them because of refeeding syndrome! When I do manage to take in more than normal I'm immediately admitted to hospital where I deal with twice-daily blood tests and constant physical monitoring to make sure I don't fucking die as a result!! Starvation mode is real and fucking scary!! "Starvayshun mode" is the biggest heap of shit I've ever heard!!
