Dear Mark: Your Brain on Junk Food

November 9, 2009

Clearly, we eat not just to fill our stomachs but to satisfy a whole host of biochemical drives. The brain is built to incentivize our efforts not just with the quieting of hunger pangs but the kick-starting of an intricate hormonal “reward” system. When it comes to diet, I’ve always said what nurtures the body nurtures the brain. The proof is in the biochemical picture. And while I wholeheartedly believe that we each choose what we eat and how we treat our bodies, there’s something to the science that shows addictive properties in junk food. I occasionally get emails on this topic. Here’s a timely one from last week.

Dear Mark,
I’m wondering if you believe in junk food addiction. I’m very new to the Primal Blueprint diet and have been having some serious issues. I feel like it’s one step forward two steps back some days. For instance, I fell […]

Warrior Fit Testimonials

First, I want to say thank you for convincing me to do Tabata! I was struggling to lose weight and Finally I found something that helped! I really appreciate your coaching! - Craig T.

Ever since I was convinced to do Tabata I have seen huge results, I lost 6 pounds and gained energy in the first 3 weeks. I have been working out for 3 months before I decided to do Tabata and I struggled to lose weight. At first I thought "How am I losing weight by bringing my heart rate up then cooling down then bringing it up again?" I don’t know how it works but it does! Thank you!! - Theresa F.

The first day of Tabata, I wondered WHAT AM I DOING - I AM 56 !! Five weeks later I knew that it was what I needed. I learned that I could push myself well beyond my comfort zone and feel good later. I have a marked improvement in physical as well as emotional endurance. - Lyn C.

When I was first told about Tabata I was very excited from the word go, however that excitement stemmed from the fact that I had no clue what it meant. I missed the first week of class b/c I was traveling for work so when I came in during the 2nd week I had some making it up to do. It was hard at first b/c my body wasn't used to working out at such a fast pace, but once I got into a rhythm I started to feel very good. These classes are no joke. If you stick with it you will leave there feeling stronger, healthier and overall better about yourself and what you've accomplished. I would recommend these classes to anyone. Darrin is a great trainer and he'll keep you going with his energy. - Jami L.
