The following formulas can be used as rules-of-thumb to determine how
many daily calories you need in order to maintain your current weight. More
importantly, these calculations will give you an idea of the maximum daily
calories allowed to reach your ideal weight goals.
You first multiply your current
weight in pounds by 10, to find the number of Base Calories. Then multiply your
current weight by 2 (not active), 5 (moderately active), or 7 (very active),
depending on your level of activity, to determine the number of Activity
Calories required. When you add your Base Calories and Activity Calories, the
total will tell you roughly how many calories you need to consume on an average day to maintain your current weight. Around
50-years-old, sarcopenia (age-related muscle loss) accelerates and we begin to
lose lean muscle mass and experience a decrease in metabolism. To accommodate
for this loss, you should subtract 10% of your total if you are over the age of
50. The final adjusted total is your baseline, or the number of calories you
need to maintain your current weight. In order to trim down, you’ll of course need
to consume fewer calories.

Here is the math behind my 50 lb fat loss in just four
months with a starting weight of 220 chubby-in-denial lbs.
220 lbs x 10 = 2,200 Base Calories
220 lbs x 5(moderate activity) = 1,100 Activity Calories
Total Calories to Maintain Weight = 3,300
Calories
Age Adjustment Calories= 0
Calories
Total Adjusted Calories = 3,300

There you have
it! I needed to consume 3,300 calories per day if I wanted to remain a fat
boy-slim tipping the scales at 220 lbs (shaking my head at just the thought).
You now know the key to fat loss is to burn more calories than you consume, or
simply consume fewer calories each day if you have yet to get your mind around
the importance of activity and exercise in your life.
This
is an example of what I consumed on a daily basis.
6:00 am: Pear or apple before my a.m. workout to break the 8 hour fast during sleep =100 calories
9 am Breakfast: Oatmeal or smoothie for breakfast after my am workout. Oatmeal=140 calories and/or whey protein smoothie = 250 calories
6:00 am: Pear or apple before my a.m. workout to break the 8 hour fast during sleep =100 calories
9 am Breakfast: Oatmeal or smoothie for breakfast after my am workout. Oatmeal=140 calories and/or whey protein smoothie = 250 calories
11 am Snack: Another piece of fruit = 100 calories
1 pm Lunch: Subway sub or another 500 calorie lunch
3 pm Snack: Nuts, carrots, or fruit = 150 calories
6 pm Dinner: 600 calories including salad and/or veggies
Daily Beverages: 100 oz of water, hot green tea, rosehips & hibiscus tea, and 0 calorie flavored energy water for lunch and dinner.
Total Daily Caloric Intake = ~1,600 calories
Therefore, 3,300-1,600 = 1,700 daily caloric deficit
3 pm Snack: Nuts, carrots, or fruit = 150 calories
6 pm Dinner: 600 calories including salad and/or veggies
Daily Beverages: 100 oz of water, hot green tea, rosehips & hibiscus tea, and 0 calorie flavored energy water for lunch and dinner.
Total Daily Caloric Intake = ~1,600 calories
Therefore, 3,300-1,600 = 1,700 daily caloric deficit
Since it takes
3,500 calories to burn 1 lb of fat, my 1,700 daily caloric deficit meant that I
would burn 1 lb of fat every 2 days (1,700x2=3,400). Although there were indeed
several periods of fat loss stalls and plateaus, the math is pretty solid. But
of course, the more fat I began to lose, the narrower my deficit became, and
the longer it took to lose even more fat. This is inevitable when it comes to
fat loss, and often our body begins to simply resist losing any additional fat
because it is more comfortable at a homeostatic state.
For Example @ 180 lbs:
180
lbs x 10 = 1,800
Base Calories
180
lbs x 7(very active) = 1,260 Activity
Calories
Total
Calories to Maintain Weight = 3,060
Calories
Age
Adjustment Calories= 0 Calories
Total
Adjusted Calories = 3,060 Calories
Even though I
had increased my activity level from “5” to “7” my body still required 240
fewer calories each day to maintain a svelte new 180 lb body weight. 3,000
daily calories is still a considerable amount to consume, and because I had
grown accustomed to consuming around 1,600 calories per day, that meant my new
daily calorie deficit was now (3,060 – 1,600 = 1,460). Since it takes 3,500
calories to burn 1 lb of fat, my 1,460 daily caloric deficit @ 180lbs now meant
that I would burn 1 lb of fat every 2.5 days ( 1,460x2.5 = 3,650).
I’m sure that
smoke is now pouring out of your ears, and I promise that is as much math as
you’ll see in the remainder of this guide. Once you truly understand the
mathematics behind your fat loss, it may help alleviate some frustrations when
you hit those inevitable fat loss stalls and plateaus. It is also important to
note that losing 0.5 – 2 lbs a week is considered a healthy fat loss and it’s
best to average it over a few months as opposed to each week. As a word of
caution, you should see significant fat loss results in the first month on your
new journey, but please do not become frustrated when the scale refuses to
budge despite your best efforts. Simply take solace in the weekly averages over
the total period of time and remember that it took a lifetime to get in the
hole, so it’s certainly understandable if it takes a few months or even a few
years to climb out and enjoy the view that a healthy new perspective brings.
