Also, what's your food lookin' like?
My diet is pretty good except for where you see spikes in my weight which is usually weekends. When I'm on my game..
1. Lots of water, starting as I get on the treadmill at 5:45am and continuing throughout the day.
2. I eat breakfast, usually right after my AM workout. This is usually 1 cup of milk, 1/2 tbsp real maple syrup, 3/4 cup frozen strawberries, splash of flax seed oil, 1 scoop of whey powder, blend that goodness up. I know this is low cals but, umm, yeah.

3. Meals are low fat, but not silly low (maybe a 1/2 tbsp of mayo on my sandwich but no cheeses, etc), high in complex carbs (no white breads, very little sugar, etc), always contain protein.
4. I then eat every 2 - 2.5 hours the rest of the day. Usually 9am, 11:30, 1:30. 4ish. These are 300-350 or so cals per meal.
That's about all i can think of right now.
