Diet | How Many Calories Can Men Really Eat?

Confused about how calorie calculators work? Here's a step-by-step guide to determining what proportion of food you would like to lose, gain, or maintain weight!

Although calorie counting seems cumbersome and is usually ignored, calories in and out remains the amount one factor affecting weight loss or gain. When you're active within the gym and need to create muscle or lose fat, it's ideal to eat the foremost that you simply can while still getting results. So, caloric intake is just about a non-negotiable measurement to stay track of.

For those eager to maintain their weight and stay healthy, knowing what percentage calories you are taking during a day also will assist you avoid health pitfalls like hormone imbalance, poor training performance, nutritional deficiencies, or undesired changes in body composition.

It's not just important to understand for the sake of appearance. With the national obesity epidemic and therefore the debilitating health issues it brings, it seems foolish to ignore the foremost effective tool we've for manipulating weight nutrition. many of us are ready to improve blood triglycerides and heart health, reduce their risk of diabetes and cancer, and live a extended , more fulfilling life once they lose unneeded weight.

On the flipside, gaining weight is how we build muscle, but there's an optimal thanks to do this without stuffing your face at every meal and putting on excess body fat.

Bottom line: It all involves tracking daily calories.

So, how does one confirm that you're getting what you would like to satisfy your goals? it is time for a few simple, straightforward steps to calculate what percentage calories you would like .
Calorie Needs For Weight Maintenance

No matter your goal, calculating your maintenance calories is that the initiative and you'll do that with basic math equations. Calorie calculators like ours are often an honest start line , but if you would like to know the physical body and obtain as on the brink of accurate numbers as possible, it's worth putting those elementary math skills to use.

The most up-to-date equation for calculating your caloric intake is that the Katch-McArdle equation. the favored Mifflin-St. Jeor equation doesn't account for lean body mass but remains accurate (within 10 percent) for many people. Both equations have shortfalls and are only an estimate of calorie needs. Katch-McArdle fails to account for total weight , age, height, or gender, while Mifflin-St. Jeor leaves out lean body mass.

For this discussion, we'll use the Katch-McArdle equation, which is well-suited for those that aren't obese and have an honest amount of muscle. it'll offer you your basal rate (BMR), which is that the number of calories necessary to sustain your various body systems: nervous, digestive, circulatory, endocrine, reproductive, and so on. The BMR doesn't include calories needed to support daily activities or exercise.

Here's the equation in kilograms and pounds:

-BMR = 370 + (21.6 x lean body mass in kilograms)
-BMR = 370 + (9.8 x lean body mass in pounds)

Step 1. Calculate Body-Fat Percentage And Lean Mass

Your lean body mass is your total weight minus the body fat. this may be the chief determinant of your calorie needs. the perfect would be to possess your body fat tested, because it is that the most accurate method, but if you've got a somewhat accurate estimation of body-fat percentage and your current weight, you've got everything you would like to work out your lean body mass.

One way to work out your body fat percentage is to live the narrowest a part of your waist, the widest a part of your hips, and your neck slightly below your larynx . Then, plug your measurements into the U.S. Navy Body Fat Calculator. The Navy method is accurate within 4 percent, it but does tend to overestimate body-fat percentage.

You can even have your body-fat percentage taken employing a caliper. This tool is inexpensive compared to hydrostatic weighing, and you'll roll in the hay yourself or have a lover or loved one help. While a caliper isn't ideal, it's inexpensive and a fast thanks to get an honest estimate.

Once you've got your body-fat percentage, it is easy to seek out your lean body mass. for instance you weigh 150 pounds, and you work out that you simply are around 30 percent body fat. meaning you're 70 percent fat-free mass.

Using basic math , 70 percent of 150 pounds (0.7 x 150) equals 105 pounds of fat-free mass.

Step 2. Determine Your Basal Metabolic Rate

As discussed, the BMR is that the number of calories necessary to sustain your body's various systems. to seek out this number, connect your lean body mass to the Katch-McArdle equation:

-BMR = 370 + (9.8 x lean body mass in pounds)
-BMR = 370 + (9.8 x 105)
-BMR = 370 + (1,029)
-BMR = 1,399 calories

In this example, your basal metabolic rate would be about 1,400 calories.

Step 3. Determine Total Daily Energy Expenditure

Your total daily energy expenditure, or TDEE, is that the total energy you burn during a day. This includes calories burned in daily activities like doing the laundry, driving, and even fidgeting, also as calories burned through exercising. An activity factor will add the required calories to accommodate your physical activity, on top of your BMR.

See the examples below to help you nail down the proper activity factor based on your activity level.

Activity Factor:
BMR x 1.1-1.2

Sedentary: most of your time spent sitting (office worker, driver, student, etc.) with little to no exercise.

Activity Factor:
BMR x 1.3-1.4

  • Lightly active: most of your time spent standing or working with hands (clerk, bartender, police officer, heavy equipment operator, etc.)
  • Sedentary with 20-30 minutes of moderate exercise per day (brisk walking, bicycling, rowing, circuit training, vigorous weight training)
Activity Factor:
BMR x 1.5-1.6

  • Moderately active: most of your time spent walking or moving objects under 25 pounds (janitor, nurse, server, electrician, courier, etc.)
  • Lightly active with 20-30 minutes of moderate exercise per day
  • Sedentary with 45-60 minutes of moderate exercise per day
Activity Factor:
BMR x 1.7-1.8

  • Very active: most of your time spent doing physical labor such as moving objects between 25-50 pounds (carpenter, mechanic, landscaper, etc.)
  • Moderately active with 20-30 minutes of moderate exercise per day
  • Lightly active with 45-60 minutes of moderate exercise per day
  • Sedentary with 2-3 hours of moderate exercise per day
Activity Factor:
BMR x 1.9-2.5

  • Extremely active: most of your time spent doing heavy labor such as moving objects over 50 pounds (roofer, construction worker, farmer, miner, etc.)
  • Very active with 45-60 minutes of moderate exercise per day
  • Moderately active with 2-3 hours of moderate exercise per day
Continuing our example, for instance you've got a sedentary job and compute 4-6 hours per week. you'd use an activity factor of 1.5 since you are not exercising a full hour every day . Multiply your BMR by your activity factor to urge your TDEE. Recall that your BMR is about 1,400 calories.

-TDEE = BMR x activity factor
-TDEE = 1,400 calories x 1.5
-TDEE = 2,100 calories

So you'd got to get approximately 2,100 calories each day to take care of a weight of 150 pounds and 30 percent body fat with lifestyle considerations. And in fact , your diet should include a healthy mixture of protein, carbs, and fat. you'll calculate the precise macronutrients with our macronutrient calculator.

Calorie Needs For Fat Loss

To achieve sustainable weight loss, I suggest a modest calorie deficit of 20-30 percent of your TDEE, and to follow that for not than six months at a time to avoid metabolic slowing.

So, if you would like 2,100 calories to take care of weight, you'd consume between 1,470-1,680 calories to lose fat. If you're already eating at 70 percent of your TDEE and have hit a weight-loss plateau, it's better to feature more activity into your routine instead of slash your food intake any longer.

Calorie Needs For Weight Gain

What about healthy weight gain? My guess is that you're trying to realize muscle, not fat. At best, a natural bodybuilder doing everything perfectly can placed on only 2 pounds of muscle per month, or half a pound per week.[4] Since a rise of three ,500 calories yields approximately 1 pound of weight gain, half a pound of gain would require a further 1,750 calories per week, or 250 calories each day .

Don't worry, we are still talking snail's pace weight gain. The goal is about 0.5-0.75 pounds per week for lean mass gains. to realize it, start by adding 300 calories to your current daily intake or start more cautiously at 200 calories if you favor and maintain that intake until you stop gaining. At that time , add another 200-300 calories and repeat.

I recommend having body-fat measurements taken every 1-2 weeks during this process to form sure your lean mass is increasing steadily while body-fat percentage barely creeps up. an honest rule of thumb is not any quite a 5 percent increase in body fat for each 16 weeks of muscle building.

Of course, it's impossible to make sure that each extra calorie you consume goes to increased muscle mass with zero increase in body fat. If only nutrient partitioning were that perfect! to really reach your lean-mass gains (that is, placed on the foremost amount of muscle possible over a period of time), you ought to be willing to simply accept alittle amount of fat gain. this is often very true if you're transitioning out of a really lean state, like post-competition.

Adjusting Your Calorie Intake

These guidelines should offer you a solid start line , but always hear your body. Your calorie needs could also be slightly higher or less than your calculations, and you'll likely got to adjust your intake supported your body's response, also as if your goals change.

For example, if you're trying to shed some fat but are losing but a pound per week, or if you're trying to feature lean mass but gaining an excessive amount of fat, cut 100 calories from your daily intake. Measure your results after one week and adjust again, if needed (always in small increments!). Or, if you're consistently losing quite 2 pounds per week (potentially losing muscle) or failing to live any increase in muscle mass while attempting a lean bulk, add 100 calories to your daily intake and track your results.

If you're maintaining well below your calculated TDEE (for example, your calculated TDEE was 2,100 calories but you have been maintaining at 1,600 calories or less), it indicates that you've got been dieting or under-eating long enough to significantly slow your metabolism. during this case, the simplest solution is to reverse diet, which is to feature calories gradually until you reach that calculated maintenance level.

Be patient when making changes. simply because you do not see results after week one doesn't suggest you ought to start one among those extreme fad diets or eat everything within the fridge. Anything worthwhile takes time, and this is often no different!
