Losing weight is tough work, but for some people, it can be especially hard. Susan Pierce Thompson, a cognitive scientist who struggled for decades with her weight, advocates a radical approach to eating that goes against popular nutritional wisdom. Instead of “everything in moderation,” Thompson advises her clients to set up clear boundaries against foods that they are at a high risk for overeating. The approach won’t work for everyone, she cautions, but it could be a “path to freedom” for others.
