Insulin Summary

Steve does a nice summary of what insulin does


But that’s not all insulin does. It also 1) impairs breakdown of glycogen into glucose, 2) stimulates glycogen formation, 3) inhibits formation of new glucose molecules by the body, 4) promotes storage of triglycerides in fat cells (i.e., lipogenesis, fat accumulation), 5) promotes formation of fatty acids (triglyceride building blocks) by the liver, 6) inhibits breakdown of stored triglycerides, and 7) supports body protein production.

Steve does not speak of insulin stopping gluconeogenesis, unless point 3 referrers to that. But then the other source or my memory could be out to lunch.

Insulin

Julianne at http://paleozonenutrition.wordpress.com/2011/10/30/nz-scientists-call-doctors-to-do-routine-omega-3-tests/  on a study calling for omega 3 testing. One quote is:

Their studies had shown omega-3 made insulin more effective and therefore improved carbohydrate and fat metabolism. That means people taking the right amount of omega-3 for their body could be less prone to developing type 2 diabetes, heart disease, or both. 


Does this imply that insulin does not have a uniform structure and is made from omega 3 or omega 6, but the stuff from omega 3 works better. Is this the "cause of obesity", more omega 6 based insulin required, aka, insulin resistance, and you know the rest of the story?

Just one more piece likely. The difficulty in maintaining a weight loss is more social- ever present food, and ever present hunger/cravings. The cravings are the worst, and nobody has a solution. Many will not even acknowledge there existence. Tobacco and alcohol cravings leave, but not food cravings. They may go for a day or two, but then these return, with a vengeance. It is the cravings that create the problem. Perhaps I must go live as a hermit, without eatable food present. Then I would be only me to drag any food home. No temptation, no cravings, no weight issue. Well maybe. 

In the weight loss cycle (lose, gain, repeat), the meals are small, far apart,and hunger is a constant companion. It is easier to deal with then the cravings. The meals are low reward, consistent, boring. That is how it must be for me to lose weight. Short cycles may be the answer to weight stability.

Weight loss diets

http://perfecthealthdiet.com/?page_id=8 Present their idea of the perfect diet.

To lose weight I need to remove pleasure foods, most of the starches, and keep the protein to about 70 grams of protein, that is 2 eggs, two 120 gram meats or fish and a bit here and there-  potatoes, flax, cottage cheese.

Their recommended quantity of starch is unreasonably large for the non physical worker/ extreme athletic, the sedentary person, inactive person, who does a minor amount of 10000 steps a day, and has a slower metabolism.

The real problem with starches; carbohydrates in general, is the other job of insulin, to inhibit lipolysis, in addiction to helping glucose into cells, and carbohydrates force the rise of insulin, as the body cannot tolerate  raised blood glucose. The inhibiting lipolysis makes us hungry, rather than using stored fats for energy. There may also be a rate of lipolysis issue when we are depleted of visceral fat.
