The Spectrum Diet

 By Mizpah Matus B.Hlth.Sc(Hons)

the-spectrum-dietThe Spectrum Diet was created by Dean Ornish, MD, who is one of the first researchers to demonstrate that heart disease can be reversed by following a strict low-fat vegetarian diet.

In this book he offers a diet and lifestyle program that can be adjusted to suit almost anyone.

Ornish acknowledges that diets don’t work in the long run so he has developed a plan that involves a gradual approach to making healthier lifestyle choices. The program is designed to be adapted to suit your genetics, unique needs, and personal preferences.

The Spectrum Diet Basics

The Spectrum is basically an outline for a healthy lifestyle that you will tailor to suit your requirements. You decide the speed and degree to which you want to move along the healthy continuum.

On The Spectrum Diet plan no foods are forbidden and you can eat anything you want. However the closer towards the healthy end of the spectrum, the greater your chance of a successful outcome, in regards to both weight loss and health.

Foods are placed into categories from the healthiest (group 1) to the least healthy (group 5).

  • Group 1: Fruits, fresh vegetables, whole grains, legumes, nonfat dairy, egg whites, soy products.
  • Group 2: Avocados, seeds, nuts, oils, canned vegetables, low-fat dairy, decaffeinated beverages.
  • Group 3: Seafood, refined carbs, concentrated sweets, oils higher in saturated fats, margarine.
  • Group 4: High-fat animal products, whole-fat dairy, mayonnaise, pastries, cookies, pies.
  • Group 5: Red meat, egg yolks, fried foods, hot dogs, organ meats, butter, cream, tropical oils.

If you are already eating the bulk of your diet from groups one and two, and do not have any major health problems, you may only need to make a few changes. However if foods in group 5 form a large part of your diet it may be necessary to make a more significant dietary adjustment.

Unlike the strict diet plans that Ornish is best known for, The Spectrum plan offers the dieter a great deal of flexibility. Small indulgences are permitted however dieters are advised to practice portion control.

Guidance is provided on how to identify your health risks as well as how to customize the diet, fitness, and stress-management components of the program to suit you individually.
