Summer is my most active time... or was before... mountain biking, hiking, camping, canoeing, kayaking, caving (spelunking) swimming, fishing and being active like that I wasn't just seated around parties with trays full of food to nibble at, I'd have what I had or we'd stop at various small stores during our trips but i was certainly burning off whatever we were eating as snacks on the trips.
Now... we're 3 days into June I haven't done any of that stuff yet and the scale says I'm not getting anywhere, that's frustrating.. but maybe I should get off here for a bit and go for a walk.

I was having the same problem. In fact, thanks to my husband who can eat all day and not gain any weight, I gained back about 10 lbs from all the grilling. The hardest part about parties is you cannot control what food is there. However, as for my own home I have found some awesome easy grilling recipes at skinnytaste.com. I love the grilled potato fries with lemon pepper Tilapia. I substituted the oil with butter flavored nonstick cooking spray to cut down a little more on the calories. I can have 2 pieces of fish with a side of potatoes fries for around 350 calories.

Another tip someone gave me when going to parties is to eat foods with high water content like watermelon and cantaloupe before you eat any other food. It fills you up so when you do eat something not so healthy your not tempted to eat too much of it.
