Eating breakfast is not a good weight loss strategy, scientists confirm

Eating breakfast is not a good weight loss strategy, scientists confirm

As nutrition researcher Marion Nestle puts it: “Many — if not most — studies demonstrating that breakfast eaters are healthier and manage weight better than non-breakfast eaters were sponsored by Kellogg or other breakfast cereal companies whose businesses depend on people believing that breakfast means ready-to-eat cereal.”

Check out the disclosures on these papers to get a sense of the conflicts: This review of observational data, which concluded that breakfast skipping is not a good way to manage weight, was funded by the Kellogg Company. Another study, which found that skipping breakfast had health costs, was funded by the Quaker Oats. Quaker also contributed to the study design — and edited the manuscript! Granted, that’s not proof that the study is wrong, but it should make one awfully skeptical.
