Is Bariatric Surgery Like Fasting in Type 2 Diabetes Treatment?

lunch time

What happens when a severely obese, diabetic patient undergoes weight loss (bariatric) surgery? If type 2 diabetes is truly a chronic, incurable progressive disease, then surgery will not alter the natural history.

According to conventional medical wisdom, long standing type 2 diabetics have very high insulin resistance provoking increased insulin secretion from the pancreas. Over time, the pancreas ‘burns out’ and insulin production falls. As the insulin falls, it is no longer able to compensate for insulin resistance and blood glucose rises, triggering the diagnosis of type 2 diabetes.

Once the pancreas burns out, nothing will revive it, meaning that type 2 diabetes is destined to progress and nothing can change that. Since this abnormality is irreversible, the diabetes should continue unabated despite bariatric surgery. Right?

Actually, in virtually all cases, the type 2 diabetes completely disappears! Continue Reading →


How to Not Get Hungry: Fasting and Ghrelin

Tea and fasting can keep hunger at bay

Ghrelin is the so-called hunger hormone. It was purified from rat stomach in 1999 and subsequently cloned. It binds to growth hormone (GH) secretagogue receptor, which strongly stimulates GH. So, for all you people who thought that eating makes you gain lean tissue, it is actually the opposite. Nothing turns off GH like food.

Of course, food provides the nutrients needed to grow, so in fact, you need both feeding and fasting cycles to properly grow. Not all feeding, and not all fasting. Life lies in the balance of the two. The cycle of life is feast and fast.

Ghrelin, has also been found to increase appetite and weight gain. It also reduces the effect of leptin (in rats at least). Leptin, as you might recall, is the hormone produced by fat cells which turns off appetite and makes us stop eating. Ghrelin turns on appetite.

So, if you want to lose weight on a long term basis, you need to tune down ghrelin. This post is about how to do that. Continue Reading →

Intermittent Fasting Does Not Cause Muscle Loss


Keith J. Harmon

No matter how often I write about this, I always get questions/ accusations that I’m lying, that fasting necessarily causes muscle loss, usually from people who never fast. But the evidence is just not there.
