Two Phases of Type 2 Diabetes

Trajectories of glycaemia, insulin sensitivity, and insulin secretion before diagnosis of type 2 diabetes: an

analysis from the Whitehall II study. Lancet 2009; 373: 2215–2221.

Beta Cell Dysfunction

Learned Helplessness

• Fact: For most people, type 2 diabetes is a progressive disease.

• eventually oral medications may not be enough to keep blood glucose levels normal. Using insulin to get blood glucose levels to a healthy level is a good thing, not a bad one.

What is Insulin Resistance?

The New Paradigm

Eat Food Store Sugar in Liver

Produce Fat in Liver Increase Insulin

No Food

“Fasting”

Burn Stored Sugar in Liver

Burn Fat in Liver Decrease Insulin

Functions of Insulin:

1.Increase glucose entry into cells

2.Turn on De Novo Lipogenesis

The ‘Lock and Key’ paradigm

“Internal Starvation” – Cannot drive DNL

The Central Paradox

Functions of Insulin (Insulin resistant cell):

1. Increase glucose entry into cells - resistant

2. Turn on De Novo Lipogenesis - supersensitive

How To Reverse Type 2 Diabetes

Type 2 diabetes is too much sugar in the body

Treatment

1. Don’t put more in – Low Carbohydrate Diet

2. Burn it off – Intermittent Fasting

Lowering glucose without raising

insulin improves outcomes
