The basal metabolic rate (BMR) and calorie calculator is an excellent tool for estimating how many calories your body needs on a daily basis depending on the amount and intensity of your exercise regime.

BMR + Daily Calorie Calculator


This BMR calculator tool works on a proven formula and is very accurate. The calculator uses two formulas to calculate your body's daily calorie requirements.

  1. 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.
  2. 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).

Hi, I'm a 22 year old female, 5'3 and weigh 111 pounds. I used to be extremely active; weightlifting 5 days a week, I was on the track and cross country team at my school so I also ran and did lots of cardio 6 days a week. I stopped all of that for a couple years and over the course of that time I developed stomach issues. I have trouble eating and digesting a lot of food, making me lose a ton of weight without really being active.

My goal is to get back into a healthy lifestyle by working out again. The calculator wants me eating 2062 calories a day. I do not think my body lets me eat enough to maintain that. Is it possible for me to gain muscle if I am eating under that number? I am very small and look unhealthy. I want to be strong mentally and physically. I would like to know if that is possible for me right now.

Hi Makala, I don't feel you need to jump straight up to that number. Not sure how much you are eating now, but you can gradually increase the number by say 100 a day per week and see some positive changes. Figure out how much you are eating in a normal day now and focus on making that small increase. I also think this is a better way to improve your digestive health and boost your confidence because you're more likely to stay consistent.

Hello! I’m looking to lose 25-30 lbs and also build muscle. Can you explain more about which supplements might help me lose weight while maintaining muscle?

Posted on: Tue, 02/27/2024 - 18:51

Hi, Amy. Thank you for reading M&S! You can learn about the best fat loss supplements here. As long as you're taking whey protein and following a sound nutrition plan, you should see an increase in muscle as well. It may only be a few pounds, but it can make a difference.

Posted on: Mon, 02/26/2024 - 17:22

Hi, I'm a 17 year old female, I'm 5'7 and 220 lbs. The BMR calculator says that my maintenance calories are at 2854, which I think is very high since I don't consume more than 1800 calories daily.

I want to lose around 65 pounds while gaining muscle at the same time, and my goal is to do this in 1.5 years. Do you think this is a realistic goal? What do I need to do to get close to my goal as possible?

I used to be 238 lbs and I got down to 220 without doing anything significant, so I don't think it'll be as hard as I used to think. I already consume around 80-100 grams of protein daily, which I could increase if I knew it was helping me achieve my goal.

Today I'm starting the 10 week women's fat loss workout on M&S, which is going to be the only form of exercise I'll be doing since I don't do anything else sports-related in my daily life. I guess I just need general advice. What do you recommend I do?

Posted on: Mon, 02/26/2024 - 18:57

Hey Xan, at your age, the 2854 is no surprise to me. Is the 1800 a comfortable number for you, or do you find yourself being hungry because you're trying to keep them low. That answer will help me provide the best guidance.

65 pounds in 18 months is doable. Building muscle along the way is also doable at your age. You may not gain much, but you will see some muscle growth just from the hard training. I definitely suggest upping your protein to at least 150 a day since you want to build muscle.

Let me know that answer as well as if you're dealing with any other health issues, and I will do my best to help.

Posted on: Mon, 02/26/2024 - 19:34

The 1800 is actually pretty comfortable, since I only eat 2 meals a day - I don't have a lot of time because of school. I normally don't get hungry other than at the times I usually eat, which are at around 12pm and 7pm. I'm not trying to keep my calories low, they kind of just are lol. I get HelloFresh delivered every week so you could also say that it's a balanced diet with vegetables, meats and carbs. I try not to eat fast food or other "unhealthy" snacks like chips and stuff, but obviously I can't say that I never have them.

I'm not dealing with any health issues other than high insulin, but my doctor says that it's only because I'm overweight, and it would go away if I lost weight, so it's temporary. I don't have any permanent health problems.

What would you suggest in order to get high amounts of protein? (Except for protein shakes since I already have those daily.)

Posted on: Tue, 02/27/2024 - 18:39

For protein, fish, greek yogurt, lean chicken, the basics that are easy to either eat right away or cook in bulk.

I do have one other suggestion for you, and this is the first time I have recommended something outside of M&S. Unfortunately, I can't share an external link, but Google the name John Robert Cardillo and look up his diet. I've worked with him on other projects, and I think his plan would serve you very well. I wish I could go into more detail, but if you look that up, you should see what I am talking about.

Posted on: Tue, 02/27/2024 - 19:08

I just read about it, and if I understand correctly, it's the 22-2 method, where he fasts for 22 hours and eats for 2. I'd definitely want to try that, though there are a couple of stuff I couldn't find answers to.

1. How long do I keep doing it? It says that if it goes on for longer than 1-2 weeks it becomes unhealthy, but it also says that he kept doing it for a couple of months and he's really healthy, so maybe there's a misunderstanding on my part.

2. Right now, I eat 2 meals a day, averaging 800-900 calories a meal, usually around 1800 a day in total. So if I start practicing his plan, do I only get 800-900 cal per day during that one meal and small snack, or do I eat the sum of both of those meals, only in a 2-hour frame?

3. As for the small snack he has at around 10pm, would a protein shake count? If not, what do you suggest? (I usually go to the gym around 10pm, so I thought that would be appropriate lol)

Also, I just want to say that you've been helpful more than anyone I've ever talked to about these stuff in my entire life, so thank you.

He actually suggests it as a lifestyle change ultimately. Clearly, you don't have to, but that is what he advocates.
I feel you could gradually decrease the calories to transition to his plan. You can eat the sum in those two hours.
A shake would count.

My pleasure to be of help. I do suggest that when it comes to his stuff, you reach out to him on his site or social media going forward. If you have any other M&S related questions, I'll always do my best to help.

I'm 44, 211 lbs 6 foot 2.

I was at 223 a few weeks ago. I did some calorie counting and went into a 800 - 1000 daily calorie deficit to lose the weight. I've been losing 2 lbs a week about.

I've been working out now for over a decade and have never been able to put on muscle without gaining lots of fat... So, I do need a little help. Can I still put on some muscle at that calorie deficit? I work out 5-6 days a week 30-40 minutes a day and add 30 minutes elliptical and 40 minute walk.

Karl, thank you for reading M&S!

First, congrats on the 12 pound loss. Well done! If you train heavy, and make sure the majority of those calories are protein, then I believe you can build muscle. To make the most out of the opportunity, I would suggest cutting back on the cardio a tad. Do the elliptical every other workout and keep your walks in. It may only be a couple pounds change, but you would start gaining muscle.

Supplements can help with this as well. Whey protein, creatine, and essential amino acids would be the three I recommend the most.

Hello. My maintenance calories are 3,218. I know going 1,000 calories below need results in around a healthy 2 pounds loss per week. But it just seems that 2,200 calories is even too high. I'm a 315 pound man previously sedentary but now doing resistance training 2x/week and cardio 3x/week.

M&S Team Badge
Posted on: Sat, 02/24/2024 - 07:08

Hey Chad, for both health and results reasons, I would suggest going 500 below on the food and shoot for 500 calories burned a day. That still comes out to your 1,000 and will keep you on a healthy weight loss trajectory while serving as a solution to your previous sedentary status. Also, up that resistance training to three times a well. Muscle will help you burn fat.

Now, once you do that and start seeing results, gradually reduce the calories more. Hopefully by that point, you can also slightly increase your activity level. I believe in the long run, this would be your best bet because you can maximize progress.

I'm 59 years old and in 2018 I had bariatric sleeve procedure. I went from 375 to 260 but since covid I have stalled. I would like to get to 200 and also bulk up. I find it hard to eat since I had 3/4 of my stomach removed. I want to consume around 175 - 200 grams of protein but often fall short.

Maintenance calories are 2480. Been lifting for a while now but the past few weeks not so much :-(

Getting back into the swing of things today training 6 days / with 6 splits. Train calves & glutes 3 times a week.

I eat clean 60% Protein / 20% Carbs / 10% Fats. My proteins are around 160g [2.2g per kilo]

Have picked up a bit of body fat - what would you advise be to drop 500 calories & shred a bit 1st & would the nutrition % above work?

Posted on: Mon, 02/19/2024 - 11:27

Hi Tanje, I think you would be okay for now since your activity is going up. After a few weeks, drop it by 500, split between protein, carbs, and fat. My guess is you will lose a little over the next few weeks and will need to adjust numbers anyway. Hope this helps!

I have re-joined the gym and planning on attending 5 times a week doing weights, which activity level do I choose? do I say moderate as that's my plan or sedentary as that's what I am at the minute? Any help would be greatly appreciated.

3300 is a great starting point, and I wouldn't go too far beyond that unless you put on significant size. Hopefully those weekends don't do too much damage, but don't feel like you can't enjoy yourself. This should be a lifestyle, not an obsession. LOL

Hi, I'm fairly new to this site, it was recommended by a friend and it is so useful, full of knowledge! I am currently trying to train in the gym 3-5 times a week, so I used that option in the BMR calculator for activity level, which gave me approx 2900 cals, so I presume to lost steady weight reduce by 500 cals to 2400, however can I just check if i want to gain/retain muscle but lose some fat, should I still reduce by the 500? Also should protein be approx 1g per lLb of weight? Thank you

Hey Simon, are you new to training or have you been in the iron game for a while? If you're new to training, then simply start training, Just getting into the routine is going to help since training will be new to your body. If you've been in the game for a while, focus on getting shredded first.

Hey Kadeem, if 2187 was the number you came up with on the calculator, then add 500 to it and that is your number. 500 calories a day is 3,500 in a week, which is the equivalent of a pound.

Hi Denae, we're happy to be a part of your fitness journey and thank you for your work as a nurse.

I believe you could get away with 150 grams of protein, which is a little over 1 gram per pound of bodyweight. Keep in mind that the protein provides the amino acids you need to rebuild those fibers after you break them down in training. If strength is the goal, then you need to eat a little more than if you were to lose weight. If you get six times a day, that is 25 grams a meal. Shakes and bars can make it a lot easier to reach those numbers.

Hope this helps, and feel free to come on back if you have more questions.

Glad you're here, Annie. Thanks for reading M&S!

I would suggest starting with 2155, 500 less than your maintenance. 3,500 calories equals one pound. So if you eat 500 less than maintenance a day, that is 3,500 over the course of a week. Combine that with your effort in training, and you could see some decent progress.

Mom of 3 down over 20lbs. Trying to shed another 20. I am currently working out 5 days a week weight training, sometimes I add walking on the treadmill. I have lost a significant amount of inches, was wondering what kind of caloric deficit I should have to drop more weight? This is the longest I've stuck with weight training and am seeing definition in my arms when I never have before. I have added weight each week and have lifted to failure each set. Are there any other tips you can give me to make sure I'm on the right track? Thank you.

Hi there! If you're seeing positive changes, do nothing different until progress stalls. Sometimes trying to make changes for faster results can actually lead to your progress stalling. You could make it a point to do the walking more than sometimes, but outside of that, ride the momentum as far as it will take you.

There is a Factor missing in the BMI Calculator: (1) Amount of Calories currently being consumed. (2) I am 129 Lbs, down from 132 Lbs on a Carnivorel Diet of 2500 Calories per Day. The 1863 Calorie Recommendation would result in even more Weight Loss. (3) Activity Level in terms of “Sports” does not apply to my Lifestyle. I sing and play Piano, (includes Intense Rock) I walk everywhere throughout every Day, and l must eat every 4-5 Hours throughout a 24 Hour Time-Frame. (4) My BMI is clearly not within “Average" Parameters, likely caused by a Hyper-Thyroid Condition contributing to Sarcopenia.

If you get cleared to work with weights, I would suggest a simple beginners routine to start out. A program like this would be a good one to consider.

I would suggest doing that workout during your eight hour eating period. Make sure you eat healthy before you train, and commit yourself to eating the healthiest post-workout meal possible. That may help with the snacking.
