*The case for getting energy from fat and ketones

When most people think of eating a low-carb diet, they tend to think of it as being a protein-based one. This is false. All traditional carnivorous diets, whether eaten by animals or humans, are more fat than protein with a ratio of about eighty percent of calories from fat and twenty percent of calories from protein. Similarly, the main fuel produced by a modern low-carb diet should also be fatty acids derived from dietary fat and body fat. We find in practice that free fatty acids are higher in the bloodstream on a low-carb diet compared with a conventional diet.[vii] [viii]

But fats also produce an important secondary fuel: 'ketone bodies'. Ketones were first discovered in the urine of diabetic patients in the mid-19th century; for almost fifty years thereafter, they were thought to be abnormal and undesirable by-products of incomplete fat oxidation. In the early 20th century, however, they were recognised as normal circulating metabolites produced by liver and readily utilised by body tissues. Ketones are an important substitute for glucose. During prolonged periods of starvation, fatty acids are made from the breakdown of stored triglycerides in body fat.[ix] On a low-carb diet, the fatty acids are derived from dietary fat, or body fat if the diet does not supply enough. Free fatty acids are converted to ketones by the liver. They then provide energy to all cells with mitochondria. Within a cell, ketones are used to generate ATP. And where glucose needs the intervention of bacteria, ketones can be used directly. Reduction of carbohydrate intake stimulates the synthesis of ketones from body fat.[x] This is one reason why reducing carbs is important. Another is that reducing carbohydrate and protein intake also leads to a lower insulin level in the blood. This, in turn, reduces the risks associated with insulin resistance and the Metabolic Syndrome.

Ketone formation and a shift to using more fatty acids also reduces the body's overall need for glucose. Even during high-energy demand from exercise, a low-carb diet has what are called 'glucoprotective' effects. What this all means is that ketosis arising from a low-carb diet is capable of accommodating a wide range of metabolic demands to sustain body functions and health while not using, and thus sparing, protein from lean muscle tissue. Ketones are also the preferred energy source for highly active tissues such as heart and muscle.

All this means that more glucose is available to the brain and other essential glucose-dependent tissues.

The case against getting energy from protein

We know, then, that dietary fats can produce all the energy the body needs, either directly as fatty acids or as ketone bodies. But, as there is still some debate about the health implications of using fats

, why not play safe and eat more protein?

There is one simple reason: While the body can use protein as an energy source in an emergency, it is not at all healthy to use this method in the long term. All carbs are made up of just three elements: carbon, hydrogen and. oxygen. All fats are also made of the same three elements. Proteins, however, also contain nitrogen and other elements. When proteins are used to provide energy, these must be got rid of in some way. This is not only wasteful, it can put a strain on the body, particularly on the liver and kidneys.

Excess intake of nitrogen leads in a short space of time to hyperammonaemia, which is a build up of ammonia in the bloodstream. This is toxic to the brain. Many human cultures survive on a purely animal product diet, but only if it is high in fat.[xii] [xiii] A lean meat diet, on the other hand cannot be tolerated; it leads to nausea in as little as three days, symptoms of starvation and ketosis in a week to ten days, severe debilitation in twelve days and possibly death in just a few weeks. A high-fat diet, however, is completely healthy for a lifetime.

Perhaps one of the best documented studies is that of the Arctic explorer, Vilhjalmur Stefansson and a colleague.[xiv] They ate an animal meat diet for more than a year to see whether such a diet could be healthy. Everything was fine until they were asked to eat only lean meat. Dr McClelland, the lead scientist, wrote: 'At our request he began eating lean meat only, although he had previously noted, in the North, that very lean meat sometimes produced digestive disturbances. On the third day nausea and diarrhea developed. When fat meat was added to the diet, a full recovery was made in two days.'

This was a clinical study, but Stefansson had already lived for nearly twenty years on an all-meat diet with the Canadian Inuit. He and his team suffered no ill effects whatsoever.

Low-carb, high-fat diet and weight loss

There is just one other consideration: If you want to lose weight, the actual material you want to rid your body of is fat. But to do that you have to change your body from using glucose as a fuel to using fat ? including your own body fat. This is another reason not to use protein as a substitute for carbs, as protein is also converted to glucose.

If you think about it, Nature stores excess energy in our bodies as fat, not as protein. It makes much more sense, therefore, to use what we are designed by Nature to use. And that is fat.
