The only sentence in the article* that quantifies the magnitude of a color dependent effect is: And while red guests reported feeling hungry and thirsty, yello

The only sentence in the article* that quantifies the magnitude of a color dependent effect is: And while red guests reported feeling hungry and thirsty, yellow guests ate twice as much. This is a pattern in science journalism: 1) scientists show statistically significant effect (sometimes minuscule in magnitude) 2) science writers describe the sign of the result without magnitude, and get some 'experts' to pontificate 3) public worries/speculates/exclaims about some new factor to think about in daily life Yadda yadda. [edit: *only sentence I saw after skimming ]
