How to visually estimate body fat percentage with pictures πŸ“Έ

If you don't know your current body fat percentage, you can estimate it pretty accurately by looking at comparison photos and reading the description of different levels.
I scoured the internet for the best body fat comparison charts.
Fair warning lots of pictures of people with various levels of body fat ahead. You don't have to be exactly accurate. Be honest. Guys usually think they are leaner than they really are, girls the opposite.

Body Fat Level Descriptions

What is your current body fat percentage?

At A pounds, with a body fat percentage of Y%, you have B of body fat and pounds of lean body mass for a total of A pounds of total mass.

What is your goal body fat %?

Remember, as a male, your abs really pop at 10% body fat, but you can set any goal you desire here.

How to get to goal % body fat

You are at a body fat percentage of Y%. With your current weight of X pounds, that means you have Z pounds of lean body mass and A pounds of body fat.
With your goal body fat percentage of goal%, you would have a goal weight of pounds, with Z pounds of lean body mass and C pounds of fat.
C fat mass / total mass = goal% body fat.
To make this calculation we assume you keep all of your Z pounds of lean mass. We just decrease your fat mass by B pounds, and you are at gender% body fat.
(Current fat mass of A - Goal fat mass of C = B pounds of fat to lose)

How to estimate your Activity Level

Studies have shown that we all overestimate how much we are active. So read the descriptions, pick where you think you are, then move down one level. For example if you think you are Moderately Active, chose Lightly Active. Since it is an estimate it just needs to be close and then you can see what the results are and tweak it.

Sedentary 1.15

You don’t intentionally exercise at all. Get up, go to work, come home, eat dinner, relax.

Lightly Active 1.2

On average, you walk for exercise about 30 minutes a day. Or you are running or lifting weights fro 15 minutes a day.

Moderately Active 1.4

If I was looking for you on a weeknight, I would call the gym. 50 minutes of vigorous exercise a day. Or about one hour and 45 minutes of walking (for exercise, not going around your house) per day. Most people do not do this.

Very Active 1.6

You move vigorously for your work (think something like construction or yardwork), or you workout every single day for more than an hour. If you were to get this level of activity only walking, it would be a nearly impossible four hours and 15 minutes of walking (again, for intentional exercise) a day.

Extra Active 1.8

Hey there Michael Phelps. Almost no one does this. This means every single day you are working out hard for an hour and a half. Or you are a professional speed walker.

Your BMR x Your Activity Multiplier gives your Total Daily Energy Expenditure or TDEE.
bmrAnswer x Activity Multiple = calories per day.


You currently have A pounds of fat.
At ?% body fat, you will have C pounds of fat.
You have to burn off B pounds of fat.
There are 3,500 calories in 1 pound of fat.
This means we know know how many calories you need to burn off by eating less. 3,500 * B = calories calories to use up.

How much energy will you eat per day?

With your TDEE of X a 25% deficit would = a number calories per day.
X - a number = 25% deficit recommended calories of energy intake per day.
Daily calories you will eat:
With your chosen energy intake of calories a day you chose, your caloric deficit is not calculated%.

Time breakdown:

It will take you X days to reach ?%.
It will take you X weeks to reach ?%.
It will take you X months to reach ?%.
It will be daysinsert in X days.

How much protein do I need?

Research shows that you need .82 grams of protein per pound of total body mass. At X pounds total body weight, you need grams of protein a day.

Final Results: Here is there's plan for abs

Here is your completely calculated and filled out checklist to get abs.
  1. βœ… Have abdominal muscles
  2. Go from Y% body fat to ?% body fat, by using up B pounds of fat, by consistently eating this many calories a day.
  3. Lift weights to keep and gain muscle.
  4. Eat much protein grams of protein a day.
  5. Sleep 7-9 hours a night.
If you do the above steps, re-calculating as your body mass changes, you will get abs in X weeks.
