How much does it take to lose an entire liter of fat? Two weeks at a 500 calorie deficit!

Body fat and calories are typically discussed in terms of mass and weight, e.g. grams and kilograms.

But I think that it can be useful to think about them in terms of volume, e.g. milliliters and liters., since it is easier to visualize the progress you have made and that wish to make.

It turns out that body fat has a specific density slightly lower than water; 0.9 kilograms per liter.

This equates to 1.1 kilograms per liter.

A kilogram of fat contains 7700 dietary Calories.

So a liter of fat contains 7000 calories.

So there are about seven calories in milliliter, 70 calories in a centiliter, and 700 calories in a deciliter, which is 10 cl or 100 ml.

So 700 calories of fat is a bit larger than a size of cube with 4.6 cm sides. Or about three espresso shots.

So to lose an entire liter of body fat, which seems like a lot, in theory you only need to sustain a 500 calorie deficit for two weeks.

That's a standard-sized beer can's worth of fat every five days!
