3 Fat Loss Hormones and Calculating Body Composition


Today’s video addresses my man Jon’s question about losing body fat and what his ideal body composition would be for fighting.

Jon’s a big dude (6’4″) and wants to fight at 205 lbs, so that puts him exactly at Jon Jones’ dimensions – perfect for Light Heavyweight IMO.

Here’s what we’ll go through in the video:

  • How to calculate fat mass and lean body mass
  • How to determine how much fat loss and/or muscle gain is needed to achieve a certain body fat %
  • 3 hormones that control your fat loss

[IMPORTANT NOTE: any and all individuals desiring rapid, sustained fat loss must watch this presentation ASAP]

These allergies are kicking my ass.

My boy Danny recommended I try this homeopathic remedy called Lufeel. I did. It didn’t work. Too bad – I want so badly to believe in homeopathy, but no homeopathic remedies have worked yet.

So I’m back on the Claritan. Downfall – I get RABIDLY hungry. Bear waking up from hibernation hungry. If I keep this up I’m going to wear out the hinges on my fridge door.

No more talk. Must go eat. Have an awesome weekend.

It was truly an honor for you to answer my question, and to use me as an example. Unreal!
I just finished my 2nd insane endurance event the Tough Mudder, thanks to your programs. Once the injuries heal up I will begin the “Xmb” program. Can’t wait. I look forward to meeting you one day.

Thanks dude,

Way to go Jon – did you enjoy the electric shocks? 🙂

Would love to link up one day. I’ll definitely look you up if I’m ever in your ‘hood.

Hi Eric,
Can you specify some way to check bodyfat %?
I have no way to access any of the fancy stuff, is there anyway to do this at home, on my own?

This is the easiest, albeit roughest calculator you can use:


Calipers are pretty good and all you need is a partner to help you… Perhaps I’ll do a video on that…
