You’ve probably heard it: nuts don’t cause weight gain.
Years ago I went back and read the studies behind that claim. Most of them weren’t weight studies at all. They were cholesterol studies — and in 14 of the 18 trials, researchers deliberately held calories constant to prevent participants from gaining weight. In some, people were weighed repeatedly, and if the scale started moving, their food was cut back.
You can’t use a study engineered to prevent weight gain as evidence that a food doesn’t cause weight gain.
I pointed this out to Dr. Michael Greger. To his real credit, he agreed, took the page down, published a correction, and thanked me publicly.
