You’ve probably heard it take as an article of faith: if you’re dieting or watching your weight, it’s probably better to eat a breakfast. Along with “drink eight glasses of water a day” and “spinach has lots of iron”, it’s taken as an article of faith. Except, like those two previous examples, it’s probably nonsense.
A new study published in the American Journal of Clinical Nutrition conducted a meta-analysis of over fifty different studies about breakfast and weight loss, and found that the evidence for breakfast having an effect of weight loss doesn’t have much scientific evidence. The idea apparently comes from a lot of small studies that show a correlation between breakfast weight loss, but they do not prove that breakfast causes the correlation, and other studies don’t back up that conclusion.
