Super-secret formula:
I"m doing Weight Watchers, now called WW. I didn't mention it at first because (1) it sounds like something old people and housewives do, (2) I wasn't sure if it works, and (3) Oprah. Not doing any dumb stuff like meetings or official weigh-ins, but just using the app.
In the program I'm using I currently get 23 points per day and 35 points per week to use. There are a lot of zero-point foods that you can fill up on, including almost all fresh fruits and vegetables (avocados are one exception I can think of), eggs, seafood, chicken, turkey...obviously only if they are not cooked in oil or whatever. Although presumably I could use all my daily and weekly points and still lose weight, only once have I ever done so. That's part one of my WW strategy, always keeping under (usually materially) my weekly allotment.
Part two relates to "activity points" that you accumulate every day. I have my Apple Health app linked to the WW app so WW automatically gives me activity points for hikes, runs, walks, etc. You can get extra food points by "switching" them for activity points that you've accumulated. I NEVER switch for extra food points. I see the activity as something entirely separate. So while it is not bostonfred approved, I don't use the activity I get to give me room to eat more. And I am also being conscious to get more exercise; my past three months have been a lot more active than my sluggish August, for instance.
Part three of my strategy is that I am insane about tracking; I don't miss anything or think "oh, I only had a little of that." As I mentioned before, I've tracked half a potato chip, and on Thanksgiving I tracked one almond.
And if in doubt, I allot a food more rather than fewer points. I don't "cheat" on tracking because what does that accomplish?
It's working well for me so far! Hoping that the progress will continue. About 11 pounds to go.
ETA: And I drink a lot, lot less wine. One 5-oz. glass equals 4 points.
