There seems to be a split between people who track their food (protein, fiber, overall calories) and people who trust that the drug will dial down their appetite enough that they don't need to track. I'm on Team Track, but that's because I really want to be sure I get enough protein and fiber (and I love data).
I don't track but I'm conscious whether I'm having smaller portions, and only 2 or 3 meals a day.
I don't worry about Protein since I basically trained myself to eat it /plan around it when I did keto.
I don't worry too much about fiber, because I tend to alternate breakfasts between either cereal or oat bran, and protein/egg bites, so I'm usually okay in that regard.
My waist has dropped enough in size that I had to get a smaller belt and I've just recently started buying a few pairs of pants in a smaller size, even though I could've done that a while ago.
I'm just not sure where my waist size is going to be when I'm at my goal weight.
My rule of thumb (for my body at least) was I lost an inch of waist for every five pounds loss. And that's consistent with what I've done in this process because I was stuffing a 44 inch waist into size 40 pants, and now I'm comfortably at 38 and hoping to go down a notch or two.
