I'm also on one of these drugs (Tirzepatide) and have been for a few months. The first time I remember knowing I was fat was when a babysitter made fun of me for it at age 6. I've been fat ever since and I'm in my late 30s now. I've lost significant amounts of weight (60+ pounds) three times in my adult life, through simple calorie restriction (intermittent fasting, including before I'd ever heard the term). Every time, I've gained the weight back. At the beginning of 2022, I was the heaviest I've ever been. I've accomplished very hard things in my life, including those that take sustained effort. Sufficient willpower isn't a problem for me in general. I honestly only ever hear "it's easy, just eat less and move more" from people that have never actually been fat. "I did it and I lost 15 pounds, no big deal!" and the like. 15 pounds is easy for me to temporarily lose too. I've done it enough times I should know ;) I've heard people say that the solution is to eat (healthy food) when you're hungry, and stop when you're full. The thing is, I'm never full. I can eat until I physically can't eat anymore (not something I do regularly, of course), and as soon as my stomach has emptied a bit, I feel fairly hungry again. "Eat until you feel full" is literally a human experience I had never really had. On this drug, I finally know what people are talking about. I still like food, and I still get hungry. But it doesn't dominate my thoughts. I eat, and don't feel like eating again for hours. I eat something that I'd normally easily eat all of like a big burrito or whatever, and I feel quite full halfway through with no desire to finish. I'm steadily losing weight, with none of the usual preoccupation with hunger, ascetic adherence to a strict calorie plan, etc. But above all, I feel like I must be experiencing what most thin people experience all the time. I'll be perfectly happy to take the drug for the rest of my life, though I do hope affordability improves. As for side effects: I've had some heartburn, but none of the other commonly reported side effects. |
I had this exact same experience when I was prescribed a drug that, as a side effect, blocked receptors in parts of the brain responsible for signalling satiety from food.
I went from having trouble eating enough food to maintain a healthy weight, and just not being hungry, to suddenly being unable to feel full at all. It was like I always had room for more, no matter how much I ate. And I was constantly hungry, felt like I was starving 24/7 and would ruminate about food so much that it impacted my ability to sleep or concentrate. My brain was obsessed with preventing me from "starving" and it ultimately dissolved the illusion of willpower that I thought I had.
No longer take that drug, but it was an eye opening experience. I didn't know that was a thing people could experience, as someone who was always skinny. It really drove home that we are products of our biology and made me more empathetic with those who struggle with food.
