I'm a male, 5'10", 220 lbs, and I'm 18 years old. I've used the different calculators/theories for discovering my BMR and just took the lowest one and used it as my guideline (just to be safe).

I'm having trouble understanding what exactly BMR and RMR do, is it that it's your body's calorie expenditure while at rest throughout the day (disregarding all excess physical activity such as running/weight lifting)?

If so, here is my question to nutritionists or individuals who have experienced great weight loss success. My BMR and RMR are in the 2200-2400 range, as stated, I've used the lowest (2200). I've also put myself on a 1000 calorie a day diet (i understand it could be unsafe, pleas edon't post to tell me so even though I appreciate all concerns). In addition to this 1000 calorie a day diet, I've decided to also burn 1000+ calories a day in excess activity, mostly vigorous running and aerobic exercise.

It's known that there are 3500 calories in a fat lb. To break it down as simply as possible, I eat 1000 calories a day, but lose 2200 without doing extra exercise, that leaves me with 1200 calories left over. But, now add my exercise into play, I manually expel 1000+ calories a day so that returns me to 2200 extra calories burned. I plan on doing this everyday 7 days a week, for a month. 2200 x 7 = 15400 excess calories burned per week. 15400/3500 calories in a lb = 4.4 lbs. In theory, I should be losing around 4.4 lbs per week.

I realize this post is long, but for those who stuck it out, I greatly greatly appreciate it. Now for my question.

Is my theory correct? Can it Work?

BMR is the body´s Basal metabolic rate - that’s is the energy expenditure without mulche activity. To get the used cal amount, you multiply the BMR with your activity level .

The formulas is not 100% perfect, the best way is to adjust the intake after 2 weeks of dieting. If you dont loss enourght, cut your intake down.

By the way! a 2000 cal shortage /day, is too much (might be dangerous)

In theory it should work but here's the catch......

First your body needs at least 1200 calories a day or it thinks its starving and will start eating your proteins (muscles) (not good not good)

Second once you start all this working out you will be converting fat to muscle and muscle weighs more than fat so you might "feel" like your plateauing for while but infact your building muscle which is what you want because the more lean muscle you have the more calories your body will burn.


Something else to think about...... I lose on average 2 to 3 pounds a week if i am really dedicated to my diet. I could work harder to lose it faster but then my body will not beable to "keep caught up" so to speak and I want my skin to tighten back up also you know? So that being said dont get discouraged if you only lose a couple pounds a week your body is doin things you cant' see and it might work out for the best in the end!

fat does not convert to muscle...fat is a stored energy source, it converts to ATP to use as energy so we can move...

Stop substituting juice and/or eating snicker bars and clean up your diet. Just push on through for a while and you'll get over it real quick. I can't really tell you how to create motivation other than to think about why it matters, really dwell in it, and use that as fuel for the fire.

If all you want is to lose some weight, it's not even necessary to give up chocolate, simply control your portions. (Hop on Google, calculate your BMR [basal metabolic rate], go to a site like fitday.com and enter your food intake, then make whatever changes are necessary to be eating 500-1000 calories less than what you need in a day). But if you want to be optimally healthy, follow the link and eat according to those guidelines.
