Don't really have a specific number in mind, more a series of checkpoints instead. Hit two so far. First was shedding a tenth of my starting weight. Then came dropping under a certain threshold. Right now the target's exiting the obese category entirely, only a couple pounds away from that, though just got back from a cruise so might be sitting a bit further off than I think, ha. After that comes losing a fifth of where I began. And beyond that, landing in a normal BMI range. Once that happens, who really knows what's next?
