Weight Loss

Dr David McCollum explains dieting.

Some of the most well known of these diets are the low fat diet, the Atkins diet and the Blood Typing diet.

Most people have been entrained with the belief that fat is bad. Indeed saturated fat (from animal products) and trans fats (fats used in baking and deep fat frying) both make people fatter and increase the chances of cardiovascular disease. However monounsaturated fats (olive oil) and omega 3 fats (found in oily fish and seeds), can actually help the body burn fat.

Research indicates that low fat diets, high in carbohydrates, actually make people fatter. There are probably 3 reasons for this:

  1. When the body is deprived of fat it stores fat to prevent a famine situation developing. Good fats burn fat!
  2. Adequate amounts of protein are needed to spare muscle tissue from being used for energy. If there is less muscle there is less tissue to burn fat.
  3. High levels of carbohydrates stimulate the body to release insulin, which forces the body to store sugar as fat. I encourage people to avoid this type of diet at all costs.

The Atkins diet emphasizes consuming large quantities of protein and fats (both saturated and unsaturated), alongside small quantities of carbohydrates.

The restriction in carbohydrates forces the body the body to burn fats through a process called ketosis. The high quantities of protein have a diuretic effect, (forces the body to expel water through urination), so weight loss appears to happen very quickly. The increased fats satiate the appetite, so the patient feels less hunger. However this diet is not without its problems.


  • Excessive protein places huge stress on the kidneys and liver.
  • The byproduct of too much protein is excess acid. This acid depletes the bones of minerals and can lead to osteoporosis. 
  • The brain needs sugar to function properly.

Present in the foods are proteins, called dietary lectins, and these lectins will react with the red blood cells causing agglutination (clumping). This process will interfere with metabolic functions, affecting the individual’s energy levels and also cause inappropriate weight gain.

Blood type, O for example, will react badly to wheat and dairy products, but will react well to red meat and high protein, whereas Type A function better on a vegetarian type diet.

The blood typing theory explains why some individuals will do badly on the Atkins diet. The Blood typing diet is one of the healthiest and beneficial weight loss and lifestyle diets available.
