Ted Naiman MD is a board-certified Family Medicine physician in the Department of Primary Care at a leading major medical centre in Seattle. His research and medical practice are focused on the practical implementation of diet and exercise for health optimization. He is also the author of The P:E Diet, which breaks down the success of every dietary strategy into one simple metric: Protein vs. Energy.

On this podcast, NBT Scientific Director Megan Hall interviews Ted about the basic levers that govern physiology and how to achieve mastery over your own body composition. Ted talks about the Protein:Energy (P:E) Ratio and why how much you eat depends on what you eat. He discusses why adequate protein is necessary for longevity and healthspan, and the differences between plant and animal sources of this critical macronutrient.
