David Allison, PhD, Distinguished Professor, University of Alabama
For several months now, my colleagues at the University of Alabama have been compiling a weekly list of selected obesity related articles in a list they call Obesity and Energetic Offerings.
Obesity & Energetic Offerings are brought to you by the UAB NORC and Office of Energetics and compiled by David B. Allison, Michelle Bohan-Brown, Emily Dhurandhar, John Dawson, and Andrew Brown.
The following is a selection of articles from this week’s list – the link headings are theirs, not mine:

- Study finds no link between kids’ obesity and DDT, PCBs.
- No evidence of improvement in rates of obesity preventive care after the Expert Committee Recommendations were made.
