NEXT SCIENCE LECTURE:
High Fat/Low Carb Ketogenic Diets: Fighting obesity by eating fat.
Thursday, October 16, 2014
Presenter: Dr. Paul Nakroshis, USM Physics Department
In July of 1976, then Senetor George McGovern held a series of hearings to discuss the impact of
diet on health, and specifically heart disease. What emerged from these hearings (to the dismay of many scientists) were nutritional guidelines that recommended eating a low fat diet, and to increase the intake of carbohydrates.
I grew up under the influence of these guidelines, and although I seemed to remain healthy for some time, once I hit my 40â€™s, my weight increased steadily until I was over 200 pounds. It was on a recent sabbatical that I had, as a side project, to do some extensive reading into diet and nutrition and to find out why my weight was increasing, independent of the fact that I substantially increased my physical activity level.
What I found was that the demonization of saturated fat was not based on good science, and that consumption of carbohydrate drives the release of insulin, and insulin is the primary driver of the storage of fat. Continual exposure to large carbohydrate intakes can make a person insulin resistant, and lead to type 2 diabetes. Based on my reading, I decided to try and test the idea that
one can lose weight by eliminating (<50 grams/day) carbohydrate and increasing the intake of healthy fats like butter, olive oil, coconut oil, eggs, and even bacon and grass-fed beef.
In this talk, I will provide details on my N=1 experiment, explain the science behind High Fat Low Carb ketogenic diets, and provide a large array of references. also discuss the potential health benefits, both in terms of weight loss, possible reduction in cancer risk, and remarkable improvements in endurance exercise.
