The third experiment: Breakfast and Weight loss

Can you take your skills from the first two questions to the next level?Try this example about the impact of eating breakfast on weight loss.Researchers recruit a group of people who had always skipped breakfast and ask them to start eating breakfast everyday.The participants include men and women of a range of ages and backgrounds.Over a year-long period,participants lose an average of five pounds.So what’s wrong with the headline:Eating breakfast can help you lose weight The people in the study started eating breakfast and lost weight—but we don’t know that they lost weight because they started eating breakfast;perhaps having their weight tracked inspired them to change their eating habits in other ways.
