I've lost about 20 lb (which corresponds to about 9 kg) recently, moving to the center from the high end of the
normal range for my height. (I'm about 5ft 10in, which is just less than 178 cm.)
I'd not been weighing myself, but my clothes were tighter than I wanted, and I was unhappy with my appearance. I guessed that I needed to lose about 10 lb. I got out a scale and weighed myself, it told me that I weighed about 168 lb (which corresponds to 76.2 kg). Based on a table that I consulted, I decided to get down to 156 lb, so I lost 12 lb.
But, looking at more tables, I was seeing that, pretty consistently, a weight of 151 lb would be dead-center in the
normal range. I decided to retarget to that. That would be another 5 lb.
Then, because my old, mechanical bathroom scale was acting-up, I got a new, electronic scale. It consistently gave a reading of about 3 or 4 lb more than did the old scale. *sigh*.
Anyway, according to the new scale, I dipped below 151 lb to-day. (That weight corresponds to about 68½ kg.) My programme was basically just one of reducing my intake of food-stuffs. I hadn't been eating a lot, but apparently my metabolism is pretty slow.
