Perhaps so. The idea is to lose the excess weight gradually (1-2 lbs. per week) and then keep it off once you reach your target. Set a ceiling at 3-5 lbs. over your target weight. If you hit the ceiling then you immediately resume the weight-loss behaviors for a few weeks to go back down. Call it yo-yoing on a really short string.
If I ever get to my target weight, I do plan to “yo-yo” in that sense! I don’t think holding yourself to within five pounds of your goal weight counts as a “yo-yo.”
By “yo-yo,” I meant of course crashing and losing 35 pounds, stuffing and gaining 40 back, slowly losing 20, creeping back up 15, crashing again for 20. . .
