2. The insulin or endocrine model

This model proposes that obesity is caused by a diet that promotes a fat-storing hormonal environment. In other words eat low carbohydrate real foods as science journalist and researcher, Gary Taubes explains:

“carbohydrates are singularly responsible for prompting insulin secretion; 2)because insulin is singularly responsible for inducing fat accumulation; 3) and dietary carbohydrates are required for excess fat accumulation; and 4) both type 2 diabetics and the higher-weight person have abnormally elevated concentrations of circulating insulin.”

Eat less carbohydrate

What this means is that eating less carbohydrate lowers the fat-storage-promoting hormone, insulin, thereby allowing the body to mobilise and burn stored fat for energy, thereby promoting weight loss/normalisation. It also means we eat less, because we’re less hungry; as previously embargoed fat stores are now accessible for burning and we don’t have to rely on diet for immediate energy (6). So, when we eat low carbohydrate real foods, we eat less and experience less hunger, which assists with body weight.

Eat low carbohydrate real foods

Over the past few decades, alongside getting fatter and eating more carbohydrate and less fat, we’re eating more processed food. Processed food is particularly good at promoting weight gain because it contains the most fattening forms of carbohydrates, often combined with the most fattening forms or fat:

Processed food contains more refined carbohydrate and sugar, with less fibre

This is a particularly obesogenic combination, boosting insulin and (addictive) reward signals in the brain to get both the body and mind to eat more. (7)

The carbohydrate is usually combined with fat

Such as ice cream, chocolates, and doughnuts. This combination is more rewarding (addictive) and prone to overeating (8). So that the fat-storing from the carbs (insulin) result in both the carbs and fat being directed into fat storage rather than being burned for energy (9).

The type of fat in processed food is particularly fattening (10)

Processed seed and vegetable oil, like sunflower, soybean, and canola oils, that are rich in the omega-6 fat called linoleic acid (LA), promote fat storage more than naturally occurring or cold-extracted oils and fats with lower LA content (e.g. tallow, lard, butter, coconut, olive, avocado, and macadamis nut oils.)
