as a swimmer, i am physically fit. however in the last year, with no major changes in my diet, i have gained about 5 pounds (not bad ). but the thing that seemed to present itself right away with the weight change, was that i was needing to increase my basal rates across the board. and i went from a TDD of 17-18 units to a TDD of 23-28 units.
this really caught me off guard. however, i am certain at least one of you has an explaination or identification with this. am i crazy for thinking this???
