DC who writes the blog is a great communicator and obviously a smart guy. However there is one comment in the post where (I think), he 'stumbles' slightly.
He picks up on Sacks' paper (Sacks et al., 2009), which compared several different diets.
- The percentages of energy derived from fat, protein, and carbohydrates in the four diets were 20, 15, and 65%; 20, 25, and 55%; 40, 15, and 45%; and 40, 25, and 35%. No difference could be detected between the different diets: all that mattered for weight loss was the total number of calories.
