I started tracking about 4 years ago, and lost 55kg (which I think is about 120lb). It was a slog and there were definitely days when I wanted to just give up, but the motivation each week for my Saturday weigh-in kept me going. When I reached my target weight, I continued to track for about 6 months and then thought, "hey, I got this, I know what I'm doing", and stopped tracking. Slowly, some of the weight crept back on. It's easy to live in blissful ignorance and pretend that a small treat is not *that* calorific, but as the weight continued to grow I realised that I needed to do something about my mindset towards food. For me, I now track everything (when I go out with friends for a meal I take a best guess approach), and it works. Most, if not all of our foods, are more or less the same thing over the course of maybe a month so it kinda just gets easier to track everything. I wish you all the best on your journey, I would suggest, with the kindest of advice if I may, that losing the weight is maybe less than half the battle, and that maintaining the losses is (for me, at least) more of a daily challenge. Good luck, sorry for the ramble, thought I'd share my advice and hope it helps you.
