skinny fat

The Four Causes of Skinny Fat

skinnyfatSkinny fat is an oxymoron

Like an under billing attorney or a Mensa society cheerleader

Skinny usually is associated with underweight, while fat is associated with overweight.

Skinny fat refers to someone with unappreciable levels of muscle mass associated to a high percentage of body fat. Basically, not a great sales point for mating season…

Here are four reasons why people achieve the skinny fat look

1

Doing too much cardio

Research is fairly clear on this. If strength and muscle hypertrophy is your goal, aerobic work will interfere with that goal. Aerobic exercise will cannibalize muscle mass.

Here are some key references:

2

Eating far too less

Of course, the natural thing to do when attempting to shed body fat is to restrict caloric intake. Skinny fat people take this axiom way too far. If you want to hold onto your muscle mass while restricting your calories, upping your protein intake is key.

To understand the mechanisms, read these research papers

Being afraid of consuming fats

Skinny fat people share dietary fat phobia as one of their pitfalls. For example, they are the ones that post on Facebook comments such as “Won’t eating nuts make you fat?”

However the research points to quite the opposite:

It makes me laugh when I see dieticians recommend “low fat snacks” such as pretzels over nuts like pistachios to obese, while the research shows them to be completely wrong:

If anything, regular nut consumption helps achieve optimal body composition.

Abstaining for strength training

Strength training has more benefits for body composition positive changes than the general population thinks:

This is what the research has to say:

Simply put, if you want to achieve a physique that spells respect, avoid the four given pitfalls.

Enjoy!
