Anyways, parent comment didn't say to starve yourself. It said to learn to be okay with being a bit hungry. Instead of learning to be okay with the feeling of hunger, people learn to be okay with the equally unpleasant feeling of being stuffed.
I did bodybuilding for ~5 years and did the whole bulk/cut cycle every 3-4 months so I had quite a few cutting session and a few times I let myself go (30-40lbs overweight) and had to lose more than 10-15lbs; in those instances I did IF (Intermittent Fasting) and ate in 6-7 hour windows (evening). The first week or so you get pretty hungry in the morning, but after that it's pretty easy.
I only say this because I want to express that I'm familiar with just being a bit hungry vs much more than that. When I was 19 I lived with a friend and we were both broke, I dropped from 180lbs to 145lbs (on my frame that was skeletal) in a few months from not eating much at all. That was pretty severe hunger, but even my ravenous after swimming isn't as bad as that was.
FWIW, and if it matters at all, I'll be 39 in a month.
