Subject: How many Cals to Eat

Ok Im 6' 255 lbs. Started at 290 lbs. This is my second year of Triathons. Training for my 4th race.  I would really like to get down to around 200 lbs if thats possible without losing muscle mass.

My first year I could eat anything I wanted and weight fell off like rain as longas I trained. Then the plat. I was actually 10 lbs heavier in my last race then I was 6 months before but with a 20 minute faster time. But the weight has not been coming off anymore. And I know Ill never get any faster at this weight. I have resigned to watch nutritional intake very closely.

I just started using the nutrition portion of this site. I like it a lot. But when I eat what I feel is a good diet I'm only coming in around 2000 cals per day. I know my BMR is around 2200-2400 Plus I train at least 5 days  per week.  I burn at least 700 cals on a workout. Sometimes more if I work out twice. So thats going to be a deficit of at least 1000 cals per day. Or a pound every 4 days.  I don't feel hungry unless its close to meals or late in the evening and I kill that with some herbal tea.  Do these numbers look ok?

There are many others on here that know much more than I do.. and I am sure they will chime in. I just know what works for me. If you want to get everything "dialed" in, have you been tested to find out your actual lean mass vs BF? How about an O2 map test? If you have these and train with a heart rate monitor, you should be able to hit the numbers that you want / need. You will know how much calories you are burning at the different ranges and where those calories are coming from...

I'd like to know this too. I have the same type of issue. Only I'm a woman.  I wonder where I can get tested.

I recently started tracking calories too. I find it frustrating because it seems like the error is so large, particularly in figuring out your basal metabolic rate. I looked on a few different websites, and came up with this (I am 5'7", 200 lb. woman):

calories to maintain current weight from the web:
3360 from priumsweb.com
2300 from health.drgily.com
2400 from dietician.com

the first site calculates BMR by multiplying your current weight by 11 (if you're a woman)! how could that be right?! actually i think it overestimates basal metabolic rate by about 500 cals. (if the other sites are correct; they use more info than just weight and gender.) so it should be more like a total of 2860. so the average of the three estimates is 2500 calories per day to maintain current weight (taking into account activity level as well as BMR). I could believe that's in the right range.... but the uncertainty is like +/- 500 calories, which makes the number practically useless, in my opinion. i don't have the expertise to say which website is best.

so anyhow... how good is your calculation of BMR? do you actually measure your foods before eating? do this for a week, and your estimates will be much closer to reality. but that's all i got. good luck! and congrats on all the weight you've dropped already!

1) Goal weight x 10 = approx RMR

2) Add cals for daily activity (not including workouts):
Sedentary: + 20 – 40% RMR
Moderate: + 50%
Active: + 60 – 80%

3) Add cals for purposeful exercise (workouts)

4) Subtract 20 – 30% of ttl caloric needs (from steps 1 – 3) to get your caloric needs for your goal weight

What does IN must go OUT!

You have to have a deficite of 500 cal per day in order to burn 1 lbs of fat a week. Know your BMI and BMR and calculate what you eat vs what you burn off.

this has me at near 1200 calories per day if I did this right. Even when I wasn't training i ate around 1500 for weight loss.

 this can't be right...unless i did something wrong. (i've done it twice). help.

gw = 165      last known - 251 (i know i'm around 238 now)    sedentary day job.

I get 2144 for you if I use 700 calories burned for workouts, 20% for the sedentary job and subtract 20% for weight loss.

Badger, I can relate to what you're experiencing. I often feel like I am not getting quite enough, but am perfectly satisfied. Judging by your numbers, it looks like your are pretty well on track. Like myself I am concerned about losing muscle mass during my training, so I don't hesitate to reach for some lean protien for a late night snack or an addition to meals. Too much caloric deficit is going to reduce your muscles significantly especially if most of your training is areobic. By adding 100-200 extra cals with a scoop of whey or a few egg whites throughout the day you'll be in good shape. I used to be about 235lbs a few years ago cut a a few too many cals during my training. Now I am a lean 155 but lost a lot of muscle in the process. I am shooting for a lean 165lbs so I try to consume about 165grams of protien per day and although it's not all that easy, it's been working. Also doing some high intensity strength training a few days out of the week will help maintain mass while boosting your calorie burning furnace for several hours after. Good luck on your goal!

I had my RMR tested back in Feb and I was about 257 and it was 2896 that is just to sustain current weigh without doing anything so if I take that into account then some of my days I am eating like 4000cals and still osing weight. Now that is big days. There are different schools of thought and I have read them all. But right now on normakl days I shoot to eat around 2500-3500 calories and still drop weight slowly.

I too struggle with weight loss. Mostly because I just really like eating not-so-good-for-ya food. My exercising has gotten much better recently and I have begun to log my activities and my food intake in a website called Fit Tracker. It supposedly figures your BMR and I am then sticking with the -500 caloric intake. I just started it and am hoping it works. Anyone else tried this?

I've not used that specific site but have used another site to track both food and exercise.  I find that food journaling  is a fantastic way to get a better sense of what I'm eating and keep it under control.  I don't do it all the time but when I start feeling like the weight has stopped coming off or my eating is out of control then I'll do it again for a period to get myself back on track.

Check out www.calorieking.com this site is a great source of information from software (which is excellent), to recipes, to health tips, etc.

There is a calculator there (under 'resources / tools') that will tell you what calories you need to consume to maintain a specific weight for your height, age and gender.

I highly recommend it.

I get 2144 for you if I use 700 calories burned for workouts, 20% for the sedentary job and subtract 20% for weight loss.   

I also get 2144 for you, given the numbers you gave.  It seems really high to me though...I cannot imagine eating over 2000 calories and losing weight.  I guess it's different for everyone.  I don't see how the formula that Cappy posted can not take into account your current conditions.  I guess I have a lot left to learn about this.

 

For me...my goal weight (for now) is 185.  I weigh about 210 currently.  I have a sedentary job.  I swim 3 times a week (45m session) calculates to 572 calories each session.  I also bike maybe once a week for 45m, which calculates to 714 calories a session.  So, total weekly exercise is 2430 calories, divied by 7 days a week is....347 calories per day burned (on average).

Am I allowed to average out my daily calorie burn like that based off weekly numbers?

Based on Cappy's calculator (using -20% for weight loss) gives me a number of 2005.

 

Now...my question.  What does this number mean?  Does that mean, this is how many calories I can/should eat daily, based on my job and exercise to maintain my goal weight?

What exactly does the -20% weight loss part mean?  20% of what?

 

 

(p.s.  2005 calories, again, seems high to me for someone in my position trying to lose weight.)

Interesting thread.  This seems more complicated then what I did.

I got my BMR from getting a test done at my gym.  I then multiplied that daily number by 7.  Next I subtracted 1k calories per day for 2lbs per week loss.  Finally, I added back the calories I burned through working out by using the number my heartrate monitor spits out at the end of the workout.

Doing this I was able to steadily drop 2lbs per week from 295-208.  After my injury at the end of last season I was sedintary and somewhat depressed over the winter so I gained some back.  Now I'm back on the same strategy gearing up for next season and its working like a charm again.

It also helps for me to have a software program I can just load everything into and trackk my progress.  I use Diet Power myself.

I actually want to get the RMR measured in the future ... it's not covered by my insurance, but I think the dietitian said it would cost $50-$60.

Agreed, it's complicated. And I also find it tough to hit the number exactly on the nose.

A very unscientific way to do this would be to track what you eat the first week (aiming for your ballpark figure), and see whether you lose or not.

Then reduce by 200 calories a week until you have 2 weeks where you lose 1-2 lbs each week. If you drop more weight than that, up the calories a little bit.
