I thought I had posted in this thread but I'm not seeing anything so I'll share mine. I started in mid-November of 2021 with my weight at an all time high of 238. Down 40 lbs to 198 as of this morning's weigh-in using a two steps forward, once step back kind of approach. Food is a bastardized combination of keto and intermittent fasting- I usually eat one meal a day and avoid any sort of starch. But I'll graze on nuts/trail mix or maybe a piece of fruit here and there. It's the only thing that works for me, and I feel like 20 months in that it's a permanent "lifestyle change" for lack of a more overused/annoying phrase. The only analytics I do is weighing every morning and logging it on a spreadsheet.
Exercise has really just been been mid-day walks by myself and then evening walks with my dog. Long ones though, usually around 3 miles. I've recently started mixing in some workouts that I can do without much more than a mat, and it's surprising how much easier/more enjoyable that is after you've dropped a bunch of weight.. Most of all, I just try to never sit still.
