Is it unhealthy to skip breakfast?Weight loss aside, Collison says she’s “totally pro-breakfast” and encourages the vast majority of her clients to eat it, for a range of reasons.“People who consume breakfast regularly often have increased physical activity. They have better dietary profiles and lower intake of snacks,” Collison says. “Skipping breakfast is associated with increased disease risk — not only obesity but diabetes, heart disease and just lower dietary quality.”One small study from 2017 suggested that breakfast-eating could improve a range of metabolic health markers, potentially improving the body’s ability to burn fat and fight chronic conditions like type 2 diabetes — at least among people who were already lean. More research is needed to know how different types of people respond to fasting, the scientists say.But what if you’re truly not hungry in the morning? Collison says that may be indicative of other problematic eating habits, like snacking at night. “If you eliminate that snacking and then wake up hungry and eat a good breakfast, your overall dietary pattern is going to be so much better, and your health status is going to be better,” Collison says.
