The article makes Wansink seem negligent and/or incompetent. Also, the embedded "CBS This Morning" video is cringeworthy. It appears that the recommendations in his book amount to "study normal weight people; do what they do." Isn't that fraught with survivorship bias? Do the recommendations in his book control for people that have the same habits but still end up overweight?
Anecdote: my household is a family of four. Myself and my wife, and our two teenage kids, daughter and son. Since we live together, the answers to the 10 questions on http://www.slimbydesign.com/get-scored/ are the same for the household. My son and I are normal weight. My wife and daughter are overweight. Conclusion: weight has very little to do with the design of your kitchen. Caveat: this conclusion has not been peer reviewed and is not scientifically sound.
