Anti-aging expert Ron Rosedale, M.D., was among the first to warn people about the
dangers of eating too much protein — a stance that has received a fair share of criticism over the years, although mounting research now offers strong support for this notion.
He was the first to help me understand the importance of insulin in 1995 and more recently the importance of protein and mTOR as discussed in the above video. I consider him my most important nutritional mentor.
The featured lecture was given in February of this year at Vail. In it Dr. Rosedale details the ancestral connection between protein, mammalian target of rapamycin (mTOR), the aging process, and cancer formation.
He starts out by offering an absolutely simple yet profound piece of wisdom in that
"your health and likely your lifespan will be determined by the proportion of fat versus sugar you burn over a lifetime."In essence, he proposes that
any food that helps you burn fat is likely beneficial for health, and any that makes you burn sugar is likely not. This is largely because sugar is a "dirty" fuel and fats and ketones burn far cleaner causing far less oxidative damage.
Hormones and the communication between them play an important role here, and those hormones are determined by the foods you eat. According to Rosedale, "you should eat today to control the hormones that will tell you what you will need to eat tomorrow."
In a nutshell, this hypothesis completely ignores the "calories in, calories out" dogma, and instead focuses on foods that support hormones and growth factors that make your body burn fat rather than sugar.
Protein Restriction — An Important Dietary Strategy for Optimal HealthThe low-carb diet made its initial appearance some 40+ years ago. In particular, it was found that low carb diets facilitated weight loss.
At the time, most people recommended replacing carbs with high amounts of protein, and these low-carb, high-protein diets (such as Atkins') worked quite well for the purpose of shedding weight.
Dietary fat was almost universally avoided, as most experts embraced the "low fat myth" and fat was thought to promote obesity and heart disease. Rosedale, however, wanted to treat diabetics, and was one of the few who promoted a high-fat diet for that purpose.
One of the primary problems with excess protein or amino acids is that it stimulates mTOR, which stimulates growth rather than regeneration. Fat calories did not stimulate mTOR, leptin or insulin. They were essentially metabolically free calories.
Rosedale found a diet high in healthy fats worked quite well for
diabetes and heart disease patients. Over time, he discovered that
restricting protein was another important factor that could affect health, and even more specifically the aging process.
