I feel like there is more to it.
Obviously, I sympathize with you, and I noticed that when I switch from a bulking cycle to a cutting cycle, it is a bit difficult to adjust for the first couple of weeks as well.
But by god, I truly am struggling to switch the other way around, and it takes me months to adjust to the bulking cycle, even with the help of stuff like weed. And when I don’t work out aggresively and don’t keep track of my cycle, it feels just natural for me to default to eating way less, as opposed to the other way around.
To be clear, this isn’t meant to be a dig at your take. All I mean is that, I feel like the whole issue is a bit more complex.
You could just have good genetics in which your body is resistant to weight gain or you have a low appetite to begin with. As shown by the worldwide obesity epidemic, this is apparently quite an uncommon problem. 75% of country overweight or obese.
This moral judgement whereby losing weight is "good" in absolute, is such bullshit. For most of history, humans have fought starvation literally every day, and often had to make do with minimal caloric intake for weeks or months - in that context, genetics that kept you thin were definitely very bad.
