## How Many Calories Should You Eat To Lose Weight?

Filed under Diet, Lose Weight | 17 Comments

Here’s a trick to calculate how much calories you should eat to lose weight:

Ideal weight (in kg) x 30 = Calories

Take your ideal weight and multiply it by 30. This should be the amount of calories you can eat a day. Of course this is not very precise because it doesn’t take important factors like lifestyle and gender into account.

Factors that influence how many calories you should eat:

• Male/female
• Active/sedentary life style
• Age
• Height
• Weight

The US Department of Health and Human Services recommend the following numbers:

Sedentary lifestyle (less than 30 minutes of moderate physical activity/day)

• Male 18-30 yo: 2400 calories
• Female 18-30: 2000 calories
• Male 31-50: 2200 calories
• Female 31-50:  1800 calories
• Male 50+: 2000 calories
• Female 50+: 1600 calories

More active lifestyle (more than 30 minutes of moderate physical activity/day)

• Male 18-30 yo: 2600-3000 calories
• Female 18-30: 2000-2400 calories
• Male 31-50: 2400-3000 calories
• Female 31-50:  2000-2200 calories
• Male 50+: 1800-2200 calories
• Female 50+: 2200-2800 calories

These numbers will maintain your current weight.

To lose weight you should increase your physical activity and reduce your caloric intake.  Try to eat 400 calories less than you are used to and you will soon start losing weight.

Did any of you stop and multiply your ideal weight by 30? If I want to be 110 pounds and I mulitply that by 30, it would equal 3300. It takes 3500 calories to make a pound.

2. Sorry, I forgot to mention that it’s weight in kilograms. 110 pounds is about 50 kg, so 1500 calories. That all seems a bit on the low side though…

3. Howdy, truly a great web site. Thx for taking the time to create all these interesting articles

4. lol I was about to say the same thing as Charlene. If it would have been in pounds, I should be a stick figure instead of a blimp. :-p Thanks for the clarification.

5. Great info to really calculate weight loss, but it’s important to also eat a proper balanced diet and each small meal you eat 5-7 times each day should have protein, carbs, essential fats, vitamins and minerals. And eat wet-based carbs like fruits and vegetables, instead of allot of breads and pastas. And don’t worry about the essential fats because they actually help burn fat in moderation.

Bascally each healthy with the calories you eat, not junk, 2000 calories of cake each day is a bad idea for your health and weight loss progress.

6. Love the method of roughly calculating your caloric intake. You will definitely need to keep an eye on the type of foods that is being eaten. The total number of calories should be spread throughout the day.

7. Wow. Lots of info and statistics. I suppose in the end it’s down to common sense and getting good habits. Thanks.

8. Ive always been a firm believere that counting calories is for the lazy, if you want to lose weight, just go work out!

9. Thanks for the info. I didn’t realize there was such an easy calculation for getting a rough estimate of calories needed. For anyone wondering how to convert pounds to kilograms, there’s an online calculator here… http://www.metric-conversions.org/weight/pounds-to-kilograms.htm (Basically you can just divide your weight in pounds by 2.2 to get your weight in kilograms)

10. It really interests me to find solutions to problems that are dealt with the mathematical way. The formula is simple and understandable enough. The next step is to put this into play.

11. I am 24 and I need only 2400 calories to keep the ideal weight? I’m not sure about that. because even though we burn some calories with less than 30 min workout a day our bodies additionally burn lots of calories for basic stuff (like breathing, blood flow, etc) + everyday action (no one sits in one place whole day)

12. Wow! That calculation is way easier that what I’ve been doing to reach my base caloric intake. Of course, then you have to adjust for the amount of activity you do, but this will make my life way easier. Thanks for sharing such a simple, common sense solution.

Just FYI. You spelled health wrong in your title of your blog. It needs to have a “T” in it. BTW, I LOVE this blog. It’s the first time I’ve come to it and will be looking practically daily for new posts. Keep up the great work!!

14. @Diane Thanks a lot for pointing out the typo! Glad you enjoy the blog…

15. This is a nice simple formula.
I do wander why an active female over 50 should be eating more than a male the same age?

16. For rapid weight loss (a difference noticed overnight) I have a total of 500 calories in a day (that includes calories burnt from exercise during the day).
