Because my scheduling has been odd the past couple of days, there's just going to be a Quickie post, and it wasn't odd because of the Superbowl, I was actually playing Skyrim while the teams were battling it out on the field.
Anyway, if you want to lose weight you need to calculate how many calories you can consume every day. Here's a quick formula to do just that.
Take your weight in pounds and multiply it by 11 (as an example 200 lbs x 11= 2200).
Take that total and multiply it by the calories you expend because of activity, if you're over 40 and are sedentary that figure is 40% or 440 calories. Add the 2 figures together. This gives you 2640 calories which is what you should be eating if you want to maintain your weight. If you want to lose one pound per week you need to subtract 500 for a total of 2140 calories per day.
Working out will increase the number of calories burned which will cause the weight to come off faster. Do not plan on losing more then 2 pounds per week, if you do you're an asshole. Because it's going to come right back on the minute you stop working out or stop watching your diet.
