So you did your math but I know me (50 5'11 maintain 175 pounds and under) and weigh myself daily/count calories/exercise a few times a week. If I see my weight go over 175 pounds I eat less calories and do more exercise.
I was in Europe in April for ten days and same amount of time in December. As noted I weigh myself daily and each time I came back i was 169 pounds and maintained my weight to under 175 for awhile the 1st time and not so long 2nd time (Christmas).
