    A recent study showed that disordered eating has negative effects on health including lower self-evaluation of health, which isn’t too surprising. What was really shocking was how common the disordered eating behaviors seemed to be in our culture.

Individually, these behaviors aren’t something to be overly concerned about, but when they add up, it became a roadblock to healthy living. Ask yourself the right questions to find out if you, too, have gone beyond healthy habits and worry about your weight.

For example, starchy(含淀粉的) foods can make people feel uneasy about eating them. Sometimes an ingredient, like fat, causes anxiety, even if it’s used to make healthy foods like olive oil. If you’re skipping foods and blaming it on an allergy(过敏) reason, but your real motivation is to lose weight, that’s a red flag.

A strict eating schedule might seem like a smart way to provide structure throughout your day, but overdoing it can leave you feeling hungry.

Not having control over how your food is prepared can be a concern, especially if you have food allergies. It’s when that anxiety is baseless and prevents you from otherwise enjoying a night out that it becomes a problem.

Tracking calories can be a useful tool to understand which foods are rich in calories, which ones aren’t, and what calorie range you should be eating. If it becomes overbearing, it’s no longer a healthy method. It’s the right way to pay attention to your hunger and satiety(饱足), and rely on those to decide when to start and stop eating.

Disordered eating is common, but it’s not harmless. Seek out help if you see yourself in these behaviors, and make sure you recognize the signs that you’re already at a health weight.
