Caloric Intake -- 1200 net cal/day for everyone?

You can't use just your BMR to calculate your daily net calories goal. This is because your BMR only takes into account the bare minimum your body needs to basically stay alive. You actually burn more calories than your BMR everyday because you don't just sleep all day - you're active and walk around, lift things, etc.

When you fill out your diet profile, we ask you for a bunch of information which we use to calculate your BMR, but we also ask you what your normal daily activity is like. We then factor in your daily activity to estimate how many calories you burn per day. To lose 1 lb. per week, you need to create a calorie deficity of 500 calories/day. So, if your goal was to lose 1 lb/week, we would take the number of calories you burn per day, subtract 500, and set that as your daily net calorie goal.

All of this is done for you automatically when you fill out your diet profile when you join the site. The one additional factor that we add in is that we never set a daily net calorie goal below 1200 to make sure your body doesn't go into starvation mode.

Does that help clarify things?

ur bmi is 10 multipied by ur current weight....if ur planing on losing the suggested calories for 1lb is 3500 per week, that is 500 per day,,,if u plan on 2 or more lbs u just double 3500/7 days,,subtracted from bmi and this is what u should consume

exerciseing,,,well u should calculate ur average calories burned after workout and those calories burned should be added to ur (final bmi)
ex: every 10 years (after 20 yrs of age)ur body decreases 2% in metobolism
so here is the math to help
age 30-39
155lbs
155 x 10 = 1550 x (2%) = 31 - 1519 ( this calorie consumption is to maintain this weight)
to lose
1lb a week (3500 cal) that is 500 per day
subtract 500 from 1519..1019
1019 is what is required to lose at least 1lb

exercising
total calories burned per day lets say 600
(you just add 600 to ur 1019,,,because u need it to balance out,,,dont want ur body to go into shock mode

You should still definitely be working out. It raises your metabolism and strengthens your heart, lungs, and other muscles. Just find something you can eat that you love, and only eat it if you work off that many calories a day. That's what I've been doing.
