Low carb weight loss doesn't cost anything, works fabulously, is sustainable, and best of all, you don't have to fight hunger!
Low carb and ketogenic (very low carb) diets are actually the way our pre-agricultural ancestors ate, and those ancestors looked much like this:
This photo is of current-day Masai people, who live on full-fat grass fed beef, milk, and other animal products, and occasional honey.
Up until about the last hundred years or so, our diet was more like that of the Masai than anything we are eating now. We ate real, whole, unprocessed food - grass-fed meat, vegetables, tallow, butter, lard, and seasonal heirloom or wild fruit. We did not eat most of our calories as wheat, corn, rice, sugar, sugar-bred fruit, highly-refined vegetable seed oils and all the highly-processed foods that contain these things.
Carbohydrate calories are cheap, shelf stable, convenient, and are now intentionally bred and engineered to be tasty, even addictive. And they have become the basis of humanity's diet in the 21st century.
People used to die largely from infectious diseases (cholera, smallpox, typhus, etc.), but more of us now die from chronic diseases (heart disease, diabetes, Alzheimer's, etc.). Why the change?
The current, near-global high carb diet has hijacked human metablolism. Here's how:
When we eat carbs - any carbs - they break down into glucose and fructose. Glucose spikes our insulin, the hormone that ferries glucose into our cells where it can be burned for energy. (And the fructose isn't used for energy at all, it is just sent straight to the liver where it is converted immediately into fat.)
Eating a carb-based diet raises our insulin levels every time we eat or snack, and when our insulin levels remain consistently high, it causes our cells to become insulin resistant.
When the cells become resistant to insulin's effects, glucose builds up in the bloodstream, which the liver then converts to fat on our bodies. Over time, insulin resistance can lead to type 2 diabetes.
Insulin also prevents the body from burning fat if there is glucose around. It says "why go to the trouble of burning fat for energy, when there's all this glucose?"
When we quit eating carbs, our insulin levels will drop, which lets us burn fat as fuel, both the fat on our bodies and the fat that we eat.
So low carb weight loss works because eating low carb keeps insulin levels low, which allows the body to burn fat instead of store it, and which will eventually reverse insulin resistance and restore our metabolic health.
All calories do not affect the body the same way. It is carb calories specifically that make us fat, because of the way they spike insulin. Dietary fat does not spike insulin.
On a low carb diet we eat more fat, and since fat is very satisfying and filling, we don't get as hungry as when we try to lose weight by restricting overall calories. This is what makes low carb weight loss sustainable.
Most of us have been taught to fear fat and to believe it causes heart disease, but this has now been proven wrong.
