erparamedic:According to www.caloriesperhour.com, I burned 533 cals doing water aerobics.
The same site has the ability to calculate the calories in many foods, even restaurants. Definately track (write down) what you eat (calorie wise) and what you burn..
Keeping track will show you were YOU make the most gains / losses...
Weight loss is different for all, sort of like diving.. You need to find what works for you. Tracking things makes it that much easier to visually see.
I track stuff in an excel spreadsheet similar to Jonnythan. I even track how much water I drink. I definately notice on the days I drink 8 + servings of water (8 oz.) my weight loss increases. The days I starve myself of water, my weight loss slows down..
Keep up the good work!
