[Preview] The carbohydrate-insulin model of obesity — Dr. David Ludwig

So according to what could be termed
the carbohydrate insulin model of obesity the problem begins
at the right side of this figure. Something has triggered fat cells
to take in and hold on to too many calories. So, there are too few calories
in the bloodstream, not too many, as in the other model
there are too few. The brain perceives that as an energy crisis,
not enough calories to run metabolism, to feed the brain, to satisfy the needs
of the other organs in the body. And so that’s why we become hungry
and wind up overeating and the brain recognizing
this potential metabolic problem also lowers energy expenditure
by making us fatigued and less likely to move, lowers resting energy expenditure,
changes muscular efficiency. Now if this model is true then the advice to just eat less
and move more will be doomed to failure and actually might make the problem worse
because it’s further going to restrict that already limited fuel supply
circulating in the bloodstream. So, what could be triggering fat cells
into this calorie storage overdrive, this feeding frenzy? Well, of course you’ve heard about insulin
quite a bit in this conference so far. Insulin is the dominant anabolic hormone
with regard to energy metabolism it regulates the availability
of all of the metabolic fuels. States have increased insulin action
not insulin levels per se, because we have to think
of insulin resistance too, but states have increased insulin action
with more secretion or injection of insulin for somebody with type 2 diabetes, or insulin promoting secreting tumors
consistently leads to weight gain. Whereas states have decreased insulin
action consistently are associated with weight loss. Such as under treatment of a child
with type 1 diabetes who can’t make enough insulin.

    Another lying dumb manipulating doctor of the system. It's a nutrient / enzyme / mineral deficiency…..Coupled with a lack of precursor elements. The masses are eternally doomed.

    0:20 "There are too few calories in the bloodstream, not too many."
    I need to see the whole presentation for the proof of this statement.
