Short Nick Norwitz video on it:

136432 person (83.5% female) prospective study
Carb, Sugar, Starch, GL ass w/ Weight Gain "Associations remained statistically significant after adjustment for energy [calorie intake], suggesting that other resultant changes (for example, changes in energy expenditure) may also lead to weight gain."
- This is consistent with Randomized Controlled Data suggesting a metabolic advantage of low-carb https://bmj.com/content/363/bmj.k4583…
Fruit and Fiber associated with less weight gain than group means, with these foods generally having lower glycemic loads
"Our findings for starchy vegetables raise concerns about the current recommendation of the Dietary Guidelines for Americans to increase consumption of all types of vegetables, specifically including starchy vegetables."

Interesting chart showing that 'French Fries make you Fat' i.e. in their substitution chart, substituting any different food for fried potato would result in less weight gain.

But we all knew that already - didn't we ?
