hyperinsulinemia, high levels of insulin in the blood, directly causes

weight gain.

Where excessively high insulin levels lead to weight gain, excessively

low insulin levels lead to weight loss.

Increasing insulin causes weight

gain. Decreasing insulin causes weight loss. These are not merely correlations

but direct causal factors. Our hormones, mostly insulin, ultimately set our body weight and level of body fat....

HYPERINSULINEMIA CAUSES OBESITY.

After all, if obesity causes insulin resistance, how could type 2 diabetes develop in normal-weight patients? And why do so many

obese people not develop type 2 diabetes?

The converse, the idea that insulin resistance causes obesity, is implausible since obesity typically predates insulin resistance. The only

remaining possibility is that some X factor is the underlying cause of both obesity and insulin resistance. The connection, as we shall see, is too much insulin. The X factor is hyperinsulinemia.

Exposure creates resistance. Excessively high and prolonged levels of anything provoke resistance by the body. This is a normal phenomenon. Consider the

following.

Since the body doesn’t want to die (and neither do we), it protects itself by developing insulin resistance,

demonstrating homeostasis.

The resistance develops naturally to shield against the unusually high insulin level...

Exposure creates resistance. Removing the stimulus also removes

the resistance.

Removing the stimulus removes the resistance. Unfortunately, the knee-jerk reaction of many doctors is just the opposite: to prescribe more antibiotics to overcome the resistance, which backfires and creates even more resistance.

Exposure creates resistance. And what does this tell us about insulin resistance? Insulin causes insulin resistance.

HORMONES, SUCH AS insulin, act much like drugs when it comes to resistance. Both act upon cell surface receptors, and they show the same phenomenon of resistance. In the case of insulin, prolonged and excessive exposure to this hormone—hyperinsulinemia—causes

For resistance to develop, two essential factors are required: high hormonal levels and constant stimulus. Normally, insulin is released in

bursts, preventing insulin resistance from developing. But when the body is constantly bombarded with insulin, resistance develops.
