Highlights
- Mystery five is that zoo animals, domestic pets, and wild animals are becoming more obese as well. This can’t be the result of changes in their diets, because lab animals, which live in contained environments with highly controlled diets, are also becoming more obese.
- Only one theory can account for all of the available evidence: the obesity epidemic is caused by one or more environmental contaminants, compounds in our water, food, air, at our jobs and in our homes, that change how our bodies regulate weight.
