This BMR tool works on a proven formula and is very accurate. The calculator uses two formulas to calculate your body's daily calorie requirements.
- Basal Metabolic Rate (BMR) Formula
The basal metabolic rate formula takes several variables like height, weight, age and gender to calculate your calorie needs as if you did not do any exercise. - Harris Benedict Formula
The Harris Benedict Formula takes the number produced by the BMR formula and multiplies it depending on your activity level.
The only factor it omits is lean body mass and thus the ratio of muscle-to-fat a body has. Remember, leaner bodies need more calories than less leaner ones. Therefore, this equation will be very accurate in all but the very muscular (will underestimate calorie needs) and the very overweight (will over-estimate calorie needs).

Calculator is working properly. Look for bold red text to appear after you submit your numbers.

Ok i'm 33 years old male. I do weight training 3 times a week sometimes 4 time depending on time. and doing martial arts twice a week and i'm about 5'9. do i really need to eat that much calories in order to build muscle? It seems a lot to me.

I am not sure if the formula is right
For example for the following data:
28yo, 59kgs, 173cm, Male, Extra Active = 2943 cals
same data for female = 2662 cals (female needs less cals)
BUT
for this case:
48yo, 40kgs, 152cm, Male, extra active = 1990 cals
same data for Female = 2065 cals (now a female needs more cals than men!)
AFAIK, a females usually needs less calories than a men, could it be an error in the BMR calculator?

Not sure what activity level I fall under. I do 4 days of lifting, 3 days of hill sprint conditioning, 4 days of 30 min. circuits, and 2 days of active recovery with a 30 minute bike ride. would that be very active or extra active?

This is amazing! Thank you so much! I'm trying to teach people that they can't lose weight and stay healthy by starving, and this is perfect! <3

I am a 37 year old female, weighing about 175 lbs, and I am 5'7". According to this calculator, I should consume 2414 calories a day to maintain my weight. I'd like to get down to 150-155 lbs by summer. If I reduced my calorie intake by 500 calories a day, would that help me reach my goal? Or would I need to reduce it by more than that. as of right now, the myfitnesspal app on my iPod tells me I should be eating no more than 1200 calories a day, but I am totally run down all of the time. I am also wondering if weight training increases metabolic rate and by how much because I do intense weight training on top of cardio 3 days a week.
Any info you can give me will help me tremendously, thank you.

Hi Yvonne,
Each person is different. I would start with 1800 calories per day for two weeks and see how your body is responding. If you aren't losing weight trying 1500 to 1600. That should do it.
Weight training can only help with weight loss. Additional muscle mass also requirements energy to maintain, so that's a bonus as well.
Posted Wed, 09/26/2012 - 16:49
Yvonne Do you add the cardio and strength training to your app? I use the same thing and the amount of calories I need goes up when I do.
Posted Fri, 03/15/2013 - 04:09
500 calorie defecit is plenty. its better to loose fat over time. 1200 might just shock your body into going into starvation mode and preserving fat because it thinks ... your starving yourself. Decrease the calories gradually as well.
Posted Fri, 03/16/2012 - 22:56
3100 calories a day? Wow. That's crazy. Still trying to lose fat too XD
Posted Sat, 04/28/2012 - 00:22
Its a factor of many things not just your BMR. Your glycemic index is just as important as you cannot lose weight if you eat 3000 calories at once in 24hr period, if you blood sugar gets too high you go into a storing extra fat phase, if you get too few you also go into a fat storing phase and even worse your body will start to consume muscle mass for energy, if you are moderately active and do cardio 3-5 times a week and lifting weights 3 times a week, if you consume your BMR you should lose fat and build muscle, its all about balance and proper nutrition. I do high intensity cardio at 7am for 20min, eat breakfast at 8, eat lunch at 11, lift weights, then protein shake at 12:30, then small meal at 3:30, then a final meat at 6. 2 days a week I allow myself to eat anything I desire as long as its in moderation so I never get bored. I used to weight 311lbs in high school, im not 30 years old and weight 209lbs at 6'0". I also can testify that a homogenous diet can help lose weight, as well as eating at the exact same times everyday keeps your body regular. Every 2 weeks change your workout routine every 2 weeks to avoid plateau. Drink 2L of water a day. Remeber the bigger and stronger a muscle is the more calories it burns when you use it, Leg workouts always seem to give me the most fat burning results, especially endurance workouts. Always do dynamic stretching in the am when you first wake up and static stretching in the pm before you sleep. And maybe most important of all, stay positive in your mind, stress is a heart killer, you have to keep yourself motivated, you cannot rely on others to make you want it. Now get out from in front of the PC and give me 20min of high intensity calisthenics...

Greetings, I have been trying to figure out the right caloric needs for my goal of losing fat without sacrificing muscle (lofty goal I know). Over 9 months I have lost 71lbs and have gone from 36% BF to 20.7(ok 21 lol)% BF but I was on what was a pretty low caloric "diet" without paying much attention to the macros. Now I am at a plateau and have realized it must be because of the diet. SO according to the calculator I need approx 3300 cals for maintenance ( 50 years young 6'6" and 234lbs with weights and cardio 4x weeks). Cutting down to 2800 cals +/- should result in the ideal 1-2lbs weight loss per week. The problem is the amount of food including protein drinks I need is causing me to be extremely full all of the time. Is this something to be conerned about? I find that i have to almost force myself to eat because I am not hungry and always feel satiated. Some problem to have I know. Anyway any suggestions??

Hi Charmin,
Calories.
Posted Tue, 03/20/2012 - 20:30
Im 28, 75 cm, 190 lbs and work out about 5 days a week. It recommends that I eat 3150 calories/day, so eating 2500-2700 calories a day should lead to a loss of 1 lb/week. The only problem is I have been eating less than 2500 cals/day for 15 months and have only lost 15 lbs. Im by no means fat, but I do still have a small gut and some fat in my stomach. What can I do to get the final gains that I'm looking for. On a side note, I have been weightlifting for 15 months and have made significant strength gains. So I guess I have lost about 25 lbs of fat.

Trying to lose 3.5pounds a week of fat and don't want to sacrifice my muscle. How can I achieve this
Posted Thu, 03/22/2012 - 09:43
Most bodybuilders aim to lose about 1.5 to 2 pounds per week. This is typically an optimal rate for many when trying to hold on to muscle mass. You can try to lose more per week, but I would make sure you are taking caliper readings every week so you can make appropriate adjustments.

Hello~ I just calculated my Daily caloric needs and it says 2042. Ive been eating about 1500/day now. Is it ok to increase that dramatically? I am trying to get lean.
Posted Thu, 03/22/2012 - 09:44
1500 is way too low unless you're female.

Hi, I'm 17 years old, female, weighing 110 pounds at 62 inches. This calculator says I should have 1600 calories to maintain weight, but most websites I come across say that teenagers should get 1800 at the lowest..Could you please clear this up for me? I'm just trying to maintain weight.
Posted Mon, 03/26/2012 - 10:16
Teenagers generally have faster metabolisms so a higher calorie intake is reasonable.

42 yrs 67" 158 Moderately active. In the gym 6 days a week. Is 2500 calories
It says I need accounting for the calories burned in the gym or I need to
Make the 2500 after deducting calories burned in gym?
Posted Tue, 03/27/2012 - 09:32
2500 sounds like a reasonable maintenance level for a 42 year old male who is training frequently. It may be a little low. If you're looking to build muscle, watch the scale, and add calories as needed if it appears to be on the low side.

Hi, I am new to nutritional information on gaining muscle mass. I am currently 20 years old at 5"11' and weigh 155 pounds at around 15% body fat. Its my goal to get to around 180 pounds and 8% body fat. Would I need more calories then this says? It currently says I need around 2766 calories
