BMR, caloric requirements, and weight loss.

I'm 5'3", 21 years old, 140lbs, female, just re-starting running (c25k, week 4, after stopping last November). My goal weight is 120 lbs, possibly 115. I'm in fairly good shape as far as muscles go but my cardio needs a lot of work.

I've been on weight watchers for 9 months and lost 15 lbs. I know that I'm not too far from my ideal weight so loss will by much slower, but this is ridiculous and driving me crazy.

According to the caloric calculators I've found, on average I should be eating 1900 calories per day to maintain my weight. That's calculated for a basically sedentary lifestyle. If you cut back too quickly, they say you won't lose because your body's metabolism slows way down. So they recommended 20%. That means I should be eating about 1500 calories per day in order to lose slowly and safely.

On weight watchers I've been eating approximately 1100 calories per day, sometimes up to 1300. How likely is it that this is why I can't lose weight? Am I really just not eating enough? And now that I'm beginning to run again, is that just making it worse?

I'm just really frustrated and I'm really questioning whether weight watchers is ever going to work for me..

Any insight is greatly appreciated..

Re: BMR, caloric requirements, and weight loss.
Well, congratulations on getting back into running. That should help in your desire to lose weight.

Do you do other types of cardio or have you been? Although, diet is probably the most important factor in losing weight, exercise helps alot and will help you get past those annoying plateaus. I would reccomend adding some cross training in addition to your running. I believe the program you're doing amounts to about 20-30 minutes of walk/running, which is great, but won't amount to an abudance of burned calories.

As close as I can figure, 1500 calories a day should result in a slow reasonable loss of weight. If you are not already splitting your calories up and eating several small meals a day then that is something you can try. I know it works a lot better for me.

Good luck!

Re: BMR, caloric requirements, and weight loss.
I think that if you already lost 15lbs, you can't say it's not working for you! Obviously you've done very well.

I would suggest worrying less about the exacted amount of calories... Just do what feels good. You can even eat the same and just add 3-4 workouts of running a week that will give you a push calorie wise.

It doesn't really seem possible to me that you aren't losing weight because you are consuming 100 calories per day less than recomended.. But if you feel that's too little add it. You may actually need it if you'll get back into running.

Anyway just take it slow and enjoy running! Stick to your routine of eating right and working out and I'm sure you'll feel better inside and out

Re: BMR, caloric requirements, and weight loss.
1200 calories and all that activity probably isn't enough. If you are eating less than 1000, that is quite unhealthy.


Gee aren't you hungry all the time? I am your height, much older and I had my RMR tested at 1250, which falls into the normal range for my height, weight and age. Yours, if normal, should be even higher. This number doesn't take into account any activity outside of just sitting on your butt.

You probably shouldn't eat less than 1300 and even that seems low considering all your activity. You need to fuel your body if you expect it to perform well.

Re: BMR, caloric requirements, and weight loss.
That sounds like too little to me, too.

I'm 28 and 110-115 lb and I definitely eat more than that. I don't count calories, but I would guess 1800 or more. I run 25-30 mpw usually and lift weights 2x per week. You sound like you're just as active, if not more.

Would a nutritionist be able to help you?

Re: BMR, caloric requirements, and weight loss.
hi Leah,

Im glad I read this because its something ive been concerned about for myself. Ive been running for 2 years now. I eat a very healthy diet, like you, probably not enough calories per day. I have been struggling with 10 pounds for the past year or so, and over the past three months Ive been steadily increasing my running and cross-training (yoga, weights, etc.), and now I am concerned that I am not eating enough, and that I am maybe 'burning the candle at both ends'. There is no way I could decrease what I am eating already in order to lose, and like you, i know that I am pushing my body beyond it's comfort level (currently running about 24-28 mpw) I dont really feel hungry, i guess because I am so used to eating the amount that i am eating now and spacing it well. I am not sure how I can go about losing that 10 pounds.

Re: BMR, caloric requirements, and weight loss.
I am also on Weight Watchers. I think your doing very well. All of us hit a slow spell at some point or other. I'm not sure why your counting calories when on WW'ers you only have to count points. You need to eat every single on of your Daily Point allowances in order to lose weight and if your earning a lot of exercise points daily I recommend eating one- two extra points on those days. I don't use my weekly allowance points but that is just me. My body doesn't need those extra points but you could be different. Your body knows, listen to it. Congragulations on all your weight loss so far. Sounds like your doing great. I'm a lifetime member now and those last 10 pounds were the hardest to lose. I only lost .4 a week or less until I reached my goal weight. For me stepping up the exercise and making sure I was fallowing program properly helped a lot. Good luck and never give up.

If you would give up the Cream of Wheat in the morning and have steak and eggs or bacon and eggs you would probably break your plateau.

It really is what you eat and not how much you eat that causes weight loss.

I really dont want to turn this into another one of "those" threads, but I just cant let a statement like this go by. So by your logic, I can eat 5000 calories of steak a day and lose weight, but if I eat 500 calories of carbs a day I'll gain weight?
I dont think I have to go any further. Cut the **** CSuzette, its getting really, really, really old.

Re: BMR, caloric requirements, and weight loss.
Hi Leah--
Are you a college student? At my undergrad campus, the health services group had a nutritionist that students could meet with for free. Something to consider if it's an option for you, just to get some more info. (cheaper than WW )
