I lost a ton of weight that way several years ago. Something about my mindset means I can't do the same thing twice though. I decided for my next push it would be a true lifestyle change. Meaning no temporary changes like eating different things than I'd normally eat, like keto or slow carb, nor forcing myself to be hungry. Neither of these tactics are sustainable over the long term. I mean, if you can force yourself to eat once a day for the rest of your life, or never eat a donut ever again, well, more power to you. I'm not that disciplined. What I can do is pay close attention to how full I feel and eat only until then, never keep going until I'm stuffed. Even then it's only for the few times a week where I'm not eating one of my portioned out routine meals. For awhile I was getting hungry during the day outside a meal so I keep pre-portioned 100 calorie snacks, usually nuts, for 3pm. As I slowly adjust my intake downwards, my need for these is slowly going away. I think when my current stash is gone, I may not need to re-up. Now I can't even really imagine doing it significantly differently. If I drove to work I'd bring a week's worth of lunch from home and precook it, but since I walk I don't want to carry all that.
