I'm not a very good source of info about losing weight. At my worst I was 20 pounds overweight. and I tried all kinds of stuff to lose weight. I got sick, lost 20 pounds and now I find staying at a healthy weight to be automatic.
IMHO, it's partly the gut biome. If yours is un-healthy then the gut's flora try to trick you into eating more. Sugar and fat combined are like heroin to them. The addictive qualities of salt, sugar and fat just add to the difficulty. Balancing your metabolism is very difficult when you are overweight - but once you have a healthy lifestyle - homeostasis takes over and it's very easy. Nowadays I suffer from no cravings, and I sometimes have to remind myself to eat. I still have some bad habits but they are more psychological than physiological.
We often speak of slow, gradual and incremental changes for transitions. But if you're overweight and addicted to salt, sugar and fat then I think the best thing is something closer to a crash course. Maybe 20 to 30 days. that month can be very tough but maybe the idea that the next month will be lots easier should help.
Oh and even now I have to moderate the nuts. Dr. Graeger says no mare than a handful a day.
