That's the crux! Constant hunger starts nagging me as soon as I try. I've tried several times for several months, with nice results from the weight's points of view, but I never got to the point where my quality of life globally increased, and that was always due to the constant hunger.
I'll only retry when I'll have found a way to stop the hunger now.
Losing weight does not have to be so hard. You can lose a lot of weight gradually over time with a small, consistent deficit. Measurement accuracy is critical, though - you will absolutely fail if you aren’t logging your food like a lab scientist.
But it is definitely possible to succeed without that constant sense of privation. In fact, if you want to succeed long-term, you HAVE to find that balance because nobody can force themselves to feel deprived indefinitely.
