There’s a reason (besides your potential tan) why you should choose outdoor seating. Restaurant diners who sit the farthest from the front door eat less salad and are 73 percent more likely to order dessert. That’s because the darker it is, the more invisible you might feel, reducing the guilt over ordering that brownie sundae. So whether you’re eating at home or dining out, have your meals in well-lit spots, such as near a window. Being in the sunlight or seeing people outside might make you more conscious about how you look and may even prompt you to order a healthy salad.
