But do we really need to be eating so much protein?
For most of us, the answer is no. David Katz, MD, director of the Yale University Prevention Research Centre, believes the protein craze is for the most part just that—another craze (albeit a long-lasting one), like low-fat in the 1980s and low-carb in the early 2000s.
"All the focus on macronutrients has been a massive boondoggle—we cut fat and got fatter and sicker; we cut carbs and got fatter and sicker," he says. "We need to stop focusing on macronutrients and instead focus on wholesome foods and healthy combinations and let the nutrients take care of themselves."
