## How Many Calories Should a Woman or Man Eat?

Instant calculation of Daily Calories

According to basic government guidelines: Men should eat 2500 Calories per day, and Women 2000 Calories per day.

This is meaningless!

We are all different shapes and sizes, and do different amounts of exercise – this is why you NEED to use a calculator.

## Daily Calories for Weight Loss

Check the fat loss range above. This is what you need to be aiming for.

You must be able to track calories each day for a minimum of a week to determine how and what you are eating. You can then begin reducing daily calories (only reduce by a maximum of 500 per day at first).

Be careful of hidden calories. Such as those in coffee drinks or sugary sodas.

## Which Foods Should You Eat?

It’s entirely possible to lose weight without any specific food restrictions – this is called Flexible Dieting. Rather than eliminate foods, you eat according to specific macronutrient levels (a set amount of carbohydrates, proteins, and fats).

Find out more in the flexible dieting guidebook.

## Calorie Maintenance Levels

Check the maintenance range above. This is how much you should be eating each day so that you WILL NOT gain weight.

Are you aware of how many Calories some foods contain? Take a look at these 300 Calorie meals (many people find these meals too small). We’ve also measured out 100 Calorie snacks for you to look at.

## How This Works

This calculator uses the Mifflin St Jeor formula, which is acknowledged as one of the most accurate predictive equations for both normal weight and obese individuals.

The calculator predicts REE (Resting Energy Expenditure). Exercise levels are then factored in. Fat loss levels are calculated by subtracting 20% of daily calories. There is always a “rock bottom” value factored in – which is 8 calories per pound of body weight.

See also, the flexible dieting macro calculator, or a nutrient calculator (multiple diets).

2. gk

How many calories should I take in daily…I am 5’2 and weigh 135 lbs…would like to lose 20 lbs..how long would it take to lose 20 lbs?

• Ted

Could you not use the calculator above?

3. Pat weeks

Since I don’t really exercise Icant eat over 700 a day to loose weight

• Ted

This isn’t healthy, Your REE is well over 700 calories so you aren’t even giving your body enough to run its basic functions on. You will actually slow your metabolism and make it harder to lose. Have a read of this article. https://healthyeater.com/eat-to-lose-weight

what is the formula that this website uses for the Calorie Intake Calculator?

8. taylor

I’m 5’7” and 160 lbs. I exercise 5 times a week and I eat rather healthy for the most part. I still lose weight, and if I don’t, I exercise more or try a new exercise. You can always lose more weight, it just depends on how badly you wish to lose it.

9. amber

Fruits, Vegetables, grains, fiber, are all good things to eat to keep your body healthy.

10. jessica

12. Jim

I use Loseit on the iphone, it’s a GREAT app for keeping track of your intake, exercise, and your progress. And it’s free.

13. Lily

Sarah; really, don’t worry. I’m sure you’re fine. 🙂 the only thing I could advise though would be to take in less and to exercise s’more. 🙂 It sounds hard but it’s okay. Keep trying, you’re 110 inside.

14. Lily

Hey there people:) Okay, so I have a question for you all. See, I’m 14 and weigh 128lbs. I do not understand this. I eat roughly 1000 calories a day, and I ride my bike 5 mile every other day or so, & I go on hikes all the time with my family. How is that I can weigh so much, and my friends who never exercise and eat twice as much as me, can weigh so much less? Am I doing something wrong?

• Marie

Hey Lily.
Your weight isn’t always representative of the amount of fat in your body. Muscle counts for weight too! A body fat percentage would be a more accurate measure of your leanness, I think.

15. Yubraj ghimire

Ya i am gonna eat exactly what this calculator set

16. Dora

I would love the spread sheet , I log what i eat but dont keep track of caloires? cant figure a logical way to do it. I am at a plateau after loosing 130 lbs and have about 10 more to go and cant get it off.please help

17. Sarah

Hi, i’m 14 years old and i’m 5’8 and weigh 144 pounds. I’m very self conscious about my weight. I’d like to loose a lot of belly fat and some in my calves. My ideal weight would be around 132-134. So if anyone could tell me how many calories i should really be eating a day and good ways to loose some belly and leg fat that would be great!!!

Thank u!

18. staci

I would love to see this spreadsheet. I am a runner and feel I do not get enough food. I am starving all day long. I love to eat too. Any pointers you can give would be very helpful. Thank you!

give me type of food which can eat to keep body in shape

20. ----------------------

Try Eating A Few Hundred Calories Below Your Daily Maintinence. Also, Try Eating Small Meals Every 3Hours Or So. This Will Higher Your Metabolism, Which Makes You Burn More Calories. Each Meal Should Be Around 200 calories (depending On Your Daily Maintenence). Try To Avoid Eating After 8:00 at Night. U should End up Eating Around 5 Small Meals A Day. Eating Small Portions Constantly Will Also Reduce The Urge To Eat Too Much. Also, Try Lifting Weights And Gaining Muscle(This Helps Burn Calories Faster). While Lifting Be Sure To Eat Plenty of Protein. Good Luck.

Loved the calculator! Thanx it helped.

23. Ice Cream

ummm so ive got all the info…
it tells me to to consume 1536 cals a day
so will this help me to lose weight or will it help me to maintain my weight??
and it says my fat loss range is 922-1229 cals. Does it mean tht i am supposed to lose 922-1229 cals a DAY??

Instead of following calculators, do your own research and experiments. Use one of these as a starting point, and try eating those numbers of calories for 1 or even 2 months. Weigh yourself every week on the SAME day at the SAME time. The best time being first thing in the morning after you use the restroom (if you have to) and with nothing on – or in underwear if you must. If after one month you are the same weight EVERY week, try going another month and seeing if you STILL stay the same. If you start at 150lbs and two months later you’re 150lbs… then bingo, that’s probably about your maintenance level. Don’t worry too much about a weekly fluctuation of 1/2 of a pound or less. You can easily store an extra 1/2 pound of water or food yet to be expelled in your body.. but a whole pound is something to take note of at least. It’s very important though that you DON’T chicken out and weigh yourself in between that weekly period. it HAS to be on the same day, time, and under the same circumstances to be accurate. Don’t drink a bunch of water the night before or the morning of and be all shocked if you gain 1-2 pounds. This is the most exact method you can get and you are sure to get something right for your bodytype. If you end up gaining 1 pound in that month, simply cut off 100 calories from the daily number and repeat the experiment. If you lose a pound, add 100 calories and repeat it.

Sorry, I meant you have to eat to “LOSE” weight.

Extremely unhealthy levels of calories. You need more calories + exercise and more muscle mass.

Physically impossible without a medical condition. Period.

Everytime I put in my weight it says enter a valid weight. How much should a 5’0″ girl who is 12 yrs. old and 70lbs eat?

30. Kat

Don’t try to gain weight! You’ll become fat and ugly !!!!!

31. Shantelle

What works for me is that I don’t eat any carbs (rice, pasta, potatoes etc.) after lunch. Also, I try to stay away from high fructose corn syrup which is definitely a no, no. The lose it app from Apple is definitely worth it but sparkpeople.com is also great.

32. Lizzy

Hi Jordan please send me the spreadsheet as well if you dont mind…

Sneaker-

That is not nearly enough food! I mean, even on a good day with that you’d be at like 500 calories and that slows down your metabolism A LOT! Eat a couple of snacks a day like the 90 calorie granola bars or more fruits and vegetables and have a proper dinner, a tablespoon of cottage cheese wouldn’t even fill up my cat. If you don’t eat more you can cause a lot of damage to your body and not even get any real weight loss because your body will slow everything down because it thinks its starving. Eat 1200 calories a day, unless instructed by a physician you should never go below that. Doing that plus some exercise and you should shed the 17 pounds in a about 1.5 to 2 months.

35. Resa

Joe-

That is just a breakdown of how calories are calculated, but you do not need to add this to the calories listed on a package. Say, for example, you have a candy bar that is 90 calories and it has 10 grams of fat (this is purely hypothetical), all the 9 calories per gram of fat is saying is that the 90 calories that comprise the bar are all from fat because 90calories/9calories per gram of fat=10 grams of fat, which is the content of the bar. The key thing to take away from how calories are calculated from fat, carbs, and alcohol is that high fat foods will be more caloric than low-fat or non-fat options, same with carbs and alcohol.

Emma –

Everyone will hit plateus at different times and considering you’re only trying to lose 16 pounds and you’re working out, your weight loss is going to be very gradual because you’ll be building muscle faster than you’ll be losing weight. I am 5’2 and I started out at 220! Now I am 164 and my goal is 130, but I have been losing weight a lot slower the last couple weeks than the first few months. This is because I am now at the point where my muscle buildup is going faster than my fat loss. If you keep losing inches and your pants are fitting better then you are doing just fine. Don’t get discouraged!! If you don’t lose anything at all on the scale for 3 or 4 weeks, then it may be time to consider revamping your regimen.

37. helen

I have lost 26 pounds in 2 months, by eating the right foods, and not over 500 calories a day, and eating 3 times a day, including a lot of fruits. My goal is to lose at least 60 pounds. and I hope to lose it. I also walk 3 miles a day, only if the weather is permitting. At first, I though that it would be very hard, but it is easier than I thought.

38. Brittany

I am a 16 year old girl that is very active but I still obsess over my weight. I am unsure of how much I need to take in a day to be healthy but lose weight. I work out almost everyday, and I play soccer and fastpitch, but I always feel like my stomach is bloated. I hate being so obssesive about eating healthy, but I can’t help it. What should I do? I’ve been eating every 3 hours and I eat very healthy things like turkey salads and fruit/veggies, but I’m not full or satisfied after I eat and I try to drink a lot of water too. someone help! :/

39. paul

If you work out the daily calorific need for your body and then reduce your intake by 500 cals a day (3500 per week) that should equate to a 1lb loss.
