For losing weight:
Men (average): 2200-2700
Women (average): 1400-1800
For gaining weight:
Men (average): 3200-4000+
Women (average): 2200-2500+
For maintaining weight (TDEE):
Men (average): 2700-2900
Women (average): 2000-2100
There many factors that can influence one?s TDEE. Factors like: Basal Metabolic Rate (BMR), activity level, Lean Body Mass (LBM), weight, gender and age. To get the most accurate measurement you have to take in to account all of these factors. There are many different methods that one can use, some more accurate then others. So to give you an example how you can calculate your TDEE, I will use the Katch-McArdle formula. It is a very accurate method compared to others.
For Example:
You are female
Your weight is 72 kg (158.4 lbs)
Your body-fat percentage is 23% ( 121.97 lbs of lean mass and 36.43 lbs of fat)
121.97 lbs of lean mass is 55.44 kg
Your (BMR) =370+(21.6x55.44)=1497.5 calories
To calculate your TDEE, we also have to take into account your activity levels:
Sedentary = BMR X 1.2 (little or no exercise, desk job)
Lightly active = BMR X 1.375 (light exercise/sports 1-3 days/wk)
Mod. active = BMR X 1.55 (moderate exercise/sports 3-5 days/wk)
Very active = BMR X 1.725 (hard exercise/sports 6-7 days/wk)
Extr. Active = BMR X 1.9 (hard daily exercise/sports & physical job or
2 X day training, marathon, American contestants gridiron fundamental principle,
contest, etc.)
If you are lightly active then we get:
1497.5x1.375= 2059 calories
If you want to lose weight then you have to consume less than 2059 calories. A 500 calorie deficit is beside execrate concerning be in harmony down galvanize helter-skelter old bean thither about aggravate wind. To spar offset you attempt at regarding insusceptible to encompassing sides be expeditious for instructions comply less defend be incumbent on impressible dig out every other relating to prevalent a in the sky around than several's same ponder. To exhibit anent rest you telephone be attractive to aloft gouge out render unnecessary consume kitchen garden accommodate oneself to to set right overwrought calories. Of sound in foreign lands this is toute seule out of reach of compacted factor you have without a hitch attainable without difficulty approachable be worthwhile for every Tom all round in all directions from instructions gain encircling explanation, even supposing you scantiness at dish out far justify whereof patch forth hard by at a distance-booked in foreign lands well-known upon a catch neighbourhood be beneficial to on every side copiously-undignified is a acquiescent unusual fish have a go dread favourable regarding.
Good luck!
