Your weight times ~10 = the number of calories your should eat a day to maintain your current weight.
Total every calorie below the calories per day youre supposed to eat and every calorie you burn exercising. 1 lb of fat lost is equal to about 3500 calories. So divide the amount of calories you didnt eat plus the number you burned by 3500 and thats how much weight you lost that day.
So say youre 200lbs. You need 2000 calories to maintain your weight. If you eat 1500 calories and burn 500 calories working out, you would lose 1000/3500lbs or .29lbs a day.
Using this site,
Calorie Counter Database - Free Online Diet Program,
and eating whatever i wanted that totaled below my calorie goal I lost about 25 lbs in 3months.
You dont need specialty diets to lose weight. You just need to know what youre eating and how much you should eat. There are probably better ways to do it but this really helped me even in the long term when deciding what to eat. Losing weight just comes down to how many calories you are below the number required to maintain your weight. I still ate pizza and cheeseburgers, i just didn't drink soda anymore and i stopped unnecessary snacks. I hope this helps.
Oh and as the post above me says, drink water or seltzer! Most people dont realize how most drinks destroy their diet.
Edit: I should also note that this method isnt totally exact. Using the spreadsheet i created i calculated i should have lost 5 lbs in the time i actually lost 9.
