From what Ive veen learning......

Obesity , storage of extra energy, develops when other areas of storage is full, like the liver. Cells fill up with triglycerides or similar, cant remember exact name. The insulin is the key to all cells , facilitating removal of excess glucose from the blood, because too much bg is harmful, so storage form is prefered.

When the fat storage becomes maximized, the cell no lo nger responds to the insulin, leaving more glucose in the blood than is ideal.

At this point, Insulin Resistance is the problem.

The level of disfunction becomes more extreme, and gets named type 2 diabetes.

Im no expert. This is what lots of reading and sluthing has revealed.

Accirding to this model, obesity is a normal storage method. Not a disease state.

Furthet reading suggested that to restore insulin senditivity, reduce the need for insulin. Not supplying MORE, but the opposite. Go keto, or fast, yo allow healing and fixing. To restore sensitivity.

Im sorry I cant remember which sources to quote. My focus at the time was to understand

1. throwing insulin at T2D is stupid and causes more damage

2. altering diet to keto or fasting will fix insulin resistance and T2D
