2 Major Factors in Weight Loss

Decreasing your calorie intake

If you eat less calories and burn more calories through physical activity, you will lose weight.

Reducing your insulin

Sugar and starch (carbohydrates) stimulate insulin release. Insulin turns on the “fat production factory” in your body. We have an epidemic of Type II Diabetes and that is just the tip of the “Health problem iceberg”

Why have we got this problem?

Just as smoking was considered acceptable in the 1960s, despite the fact that scientists knew that it was causing cancer, we need to make people aware of the importance of insulin and health problems associated with obesity. Reducing carbs and therefore reducing insulin output is the secret.

Why change?

If you have developed tiredness, brain fog, and you are becoming more and more overweight, it is time to take control of your life. Modern medical advances are allowing us to live longer but we have to make sure that the last 10 to 20 years of our lives are healthy, not with alzheimers, diabetes, cancer and heart disease languishing in an aged care facility.

  • “Dr John Stewart's dedication to nutrition science is very impressive.  He has helped me better understand and apply the scientific basis of nutritional strategies for the avoidance of pre-diabetes.  A supermarket shopping trip is now very different with that knowledge at hand. ”
    Dr David Evans, BVSc PhD
  • He came to our home . I was pleasantly surprised when I had the meeting with Dr John. He spent 1.5 hours with us rather than the one hour that I paid for. He identified that I wasn't eating enough high quality protein ( containing essential amino acids) . Now I am eating salmon every 2 nd day , which is giving me more Omega 3 fatty acids. I am eating more oysters ( protein and Zinc). I liked the way Dr John got my husband involved in the modifications to our diets.

  • We won a consultation with the nutrition science group at a charity auction ! I already knew a lot about healthy eating but Dr John ( and Professor Ben Bikman) added a "new dimension" by teaching us about the bad hormonal changes that take place when you eat sugar and starch ( which I love ) . I have swapped out bread made from gluten containing grains wheat, Rye, Barley for bread made from almond meal . I have also doubled my egg intake ( 3 a day ) for its high quality protein . I am off all pasta, potato and Rice . We have lost 30 kgs between us in the last 5 months and keep each other from cheating !
