How Many Calories Should a Man Consume Daily?


Sedentary Males

Sedentary males from 18 to 40 years old need around 2,400 calories, according to the U.S. Department of Agriculture. The sedentary male's caloric needs decrease to 2,200 from age 40 to 60, then drop to 2,000 for the remainder of the lifespan.


Moderately Active Males

Men who exercise for around 30 minutes a day on a regular basis are categorized as moderately active by the U.S. Food and Drug Administration. Moderately active men who are 18 to 25 years old need about 2,800 calories per day. From 26 to 45, the recommended caloric intake dips to 2,600. From 46 to 65, it hovers around 2,400 before dropping to 2,200 for men 66 to 75. Moderately active men over 75 need about 2,000 calories.

Active Males and Athletes

Highly active men must put away a lot of calories to maintain their weight. Men 18 years old need as much as 3,200 calories. Men 19 to 35 need about 3,000 to fuel an active lifestyle. Men 36 to 55 need to take in about 2,800, while those 56 to 75 should try to consume around 2,600 calories. Active men over 75 need 2,400 calories.

Your daily caloric intake Calculator

BMR
There are many ways of determining personal daily caloric intake, one of which is called the Harris-Benedict Formula . It is the easiest way to calculate Basal Metabolic Rate (BMR). It factors in gender, bodyweight (in kilograms), height (in centimeters), and age. The formula works as follows:
*Note that 1 kilogram = 2.2 pounds; 1 foot = 30 centimeters

BMR = 66 + (13.7 x weight in kg) + (5 x height in cm) - (6.8 x age in years)
For example: 1- Male: 66 2- Weighing 75 kilos: (13.7 x 75) =1,027.5 3- 175cm tall: (5 x 175) = 875 4- 28 years old: (6.8 x 28) = 190.4
Add steps 1 to 3 and subtract step 4 from the total, which should amount to 1,778.1.
Wait, you may need more calories...

Sedentary = BMR X 1.2 (little or no exercise)
Lightly active = BMR X 1.375 (light exercise 1-3 days a week)
Moderately active = BMR X 1.55 (moderate exercise 3-5 days a week)
Very active = BMR X 1.725 (hard exercise 6-7 days a week)
Extremely active = BMR X 1.9 (heavy daily exercise)


In this case, if the male from the example above is moderately active, take 1,778.1 and multiply it by 1.55. This raises the amount of calories to 2,756 each day.

ATT U-VERSE DSL modem经常死机的问题及解决办法

近一周来,家里的ATT U-VERSE经常当机死掉,必须重启,但不久又死掉。打电话去ATT寻求支持,技术人员一通胡侃,问题丝毫没解决。后来俺发现ATT设置的DNS SERVER有问题,所以造成上网访问某些网页速度很慢,或者说找不到该网页,最后MODEM死机。换了DNS SERVER设置后问题解决。 俺家的位置选: 208.67.220.220和 68.94.156.1 效果很好。其他读者可以下载GOOGLE 的 benchmark 软件决定最佳DNS SERVER的 IP 地址。
