What do think is the most common mistake people make with their nutrition?

I believe most people don’t match the quality of their nutrition to the incredible physical demands they place on their bodies.

Did you know most people select less than 20 different foods in their lifetime.

Often, when people decide to "get lean" or get “in shape” they severely limit there food choices. Most make no more than 5 food choices a week!

Chicken, rice, oats, egg whites, a protein supplement and maybe some green beans -sound familiar?

It's a narrow-minded, lazy approach that knee-caps your ability to achieve optimum health and peak performance, let alone create the metabolism for permanent fat loss.

Increased food variety is one of the most effective ways to get the most from your training.

There is a simple rule you can follow that will dramatically increase the nutrition of your plan: Dine by Colour!

Take a god look at each meal you eat - how colourful is it?

Research shows the more colour, the more nutrition and great fat-burning potential.

When purchasing foods go for bright colours (and I’m not talking about the design on the cereal box either!) For example, when choosing vegetables and fruits, (yes, fruit should be a staple of every transformation plan), instead of the usual bananas and potatoes, chose blueberries, raspberries, kiwi fruit, cantaloupe/melons.

Capsicum, pumpkin, squash and greens such as broccoli, kale and spinach should be your first choices in the produce section.

Follow this simple advice for the next three months. I can virtually guarantee you will double the improvements you've experienced in the previous three months.
