Any movement will do a lot for you. Not just for weight loss either. So... I'm a little confused.... where did the 240 number come from? Was that the weight you were when you last weighed yourself and because you didn't feel or see a difference physically you assumed you were still at that weight? I doubt you are carrying 35 pounds of water weight, sorry to say. Maybe 5-8 pounds (at the most) is from water. You are very tall so gaining 35 is completely different for you than it would be for me and that's probably why you haven't seen too much difference in how your clothes fit. And for me, I don't measure myself accurately because I can never seem to get the tape measure in the same place each time! LOL
I don't know. But regardless of whether you are 240 or 275, eating right and exercising is the path you want to be on!
Good luck hun.
