Core Principle 1

Eliminate grains & other starchy carbohydrates from your diet

Core Principle 1

I do not believe that humans are supposed to eat grains, especially processed grains. Grains are just sugars, but in a different state, not refined like the white crystals we think of as household sugar. But inside your body, they are broken down into sugars and like all sugars they stimulate an insulin response that causes your body to store excess calories as fat. In short, eating a lot of white carbs and starches – that’s bread, cereals, pastry, pasta, white potatoes, spaghetti and white rice – makes you fat. Also, this insulin response, repeated often enough, becomes unhealthy, damaging your pancreas and leading to adult-onset diabetes.

Starchy carbohydrates are a poor choice of fuel; they are not helping your body to work at its most efficient. Additionally, many people are intolerant of gluten (and wheat), and grains can cause numerous stomach, bowel and digestive problems.

You cannot digest grains in their natural state. The plants are cellulose-based grasses, and the grains (their seeds) are not digestible unless we process them. For many years, humans processed those grains by simply crushing them (grinding between heavy stones, milling) and then mixing them with water to make a basic kind of porridge or gruel. This way they became digestible, but they were always considered an extremely poor choice of food – the food of poverty.

Small amounts of natural carbs have some use. Some carbs in the diet provide a ready source of sugar-based energy, particularly useful for those who are very physically active. Most vegetables provide some good natural healthy carbohydrate and some fibre, but I limit my carb consumption to just that, just what comes from vegetables. Broadly speaking, I believe our bodies run best on fat as our primary fuel.

Now to many of you, that may run contra to much of what you have heard before. The diet industry has spent many years teaching us that fat is the enemy, fat makes you fat. However, I strongly believe that we are supposed to ‘run on fat’ – not sugar – as our primary source of energy. Personally, most of my fuel for activity primarily comes from fat. I eat some fresh fruit (bananas, apples) and a little dried fruit (sultanas, raisins, dates), which provides a little sugar hit now and then, but that’s about it.

Fat is a far more efficient fuel, with twice as many calories per gram as carbohydrate, and I personally find my energy levels much more stable now I have trained my body to be a ‘fat-burner’, not a ‘sugar-burner’.

You are what you eat! And I don’t know about you, but I don’t want my body shape to look like a big blob of starchy potato! Mr Potato Head might be happy looking that way, but it’s not for me, so I am not going to eat starchy carbs, grains or white potatoes.


  • Eating white carbs and starches – that’s bread, cereals, pastry, pasta, white potatoes, spaghetti and white rice – makes you fat
  • Too many carbs can lead to a damaged pancreas and can contribute to Type 2 diabetes
  • Eating moderate amounts of fat does not make you fat if you lead an active lifestyle
  • Eat potatoes to look like Mr Potato Head!
