Understanding Fat: Syndrome X and Beyond

Ronald M. Evans, Howard Hughes Medical Institute Investigator, examines environment, lifestyle, diet, marketing, and biology as contributors to the obesity epidemic. How do our bodies balance the storage and burning of dietary fat? Fat carries information about how it should be used. Saturated fats are hard to break down, so they tend to get stored, while unsaturated fats are more readily consumed for energy. Too much stored fat leads to elevated blood glucose levels, which triggers insulin resistance -- the first step toward diabetes. Dr. Evans explores how diet and exercise influence the relationship between fat and muscle, precipitating diseases such as syndrome X, a disorder involving high blood pressure, heart disease, atherosclerosis, and insulin resistance.

fats are not just used for burning but cell structures as well, these membrane structures are turned over as the fats, cholesterol and proteins are oxidized and damaged by oxygen and free radicals. our cells membranes are about 50 percent or more fat, mostly saturated, some cholesterol and mono fats and protein matrix. lack of exercise has nothing to do with it either, exercise only increases needs for energy hence tendency to increase appetite and some weight gain in many.

sugar is not the problem is how fast and how much builds in the blood if your cells are resistant to glucose it matters not if the glucose comes from pop or whole grain cereal. you must address the underlying cause and your cravings for the sugary stuff will dissappear considering body controlled eating will not let you over eat even if you get extra, you just end up throwing it away.

malnutrition will lead to resistance. fat cells buffer such excess glucose to protect you from glycation

Obesity is a reaction to PUFAs and fructose.

This is part of a series of lectures on the overall topic of obesety. This particular lecture is about social and behavioural factors of obesety and in the second part about the effect of obesety on the human metabolism. It is not supposed to be a guide to losing weight in the first place and doesn't proclaim to be. A complete video abot human energy metabolism would be about 99999 hours long. Incomplete on the other hand is your statement on a all fat and no carb diet wich is highly simplistic.

@rwrp I agree saturated fats are healthy. Nourishing Traditions and a book called the Cholesterol Con validate the benefits of saturated fat in longevity and well being.

i find it silly that he lives out sugars role in obesity. And also how high fat and high carb make you fat. Not just fat. If you eat all fat and no carb u lose weight. I felt this video was incomplete and gives incomplete information misleading people

[rwrp]

Blanket bias against saturated fats is total BS!
