Hey all. I keep kicking back into the habit of lurking even though I have an account. I have a quick question, but first a reintroduction: last fall I got back into checking this site regularly as I was losing weight regularly. I was a member at a gym and had a much more flexible school schedule. This semester, more rigorous school schedule, and had to cancel the gym membership for financial reasons. About a month ago, my weight was back up to 259 so I started focusing on my eating habits and not exercising as much (once a week for an hour)and came down to 241 when I weighed myself last Friday morning. However, Friday night, I played tennis (poorly and amateurly) from 2-6 and when I weighed myself this morning, I was up to 245. What's going on? I'm keeping my deficet at 400cals a day, but why the sudden weight gain?
