Since when do those of us who are not "fat" always stop eating when we feel full? ("Heavy on the Activism," Dec. 27). Tell me about "fat acceptance" when there are food diaries or other evidence that obese people are eating reduced-fat meals, exercising and consuming fewer than 2,000 calories a day. If there is a gene that results in obesity despite taking care with one's eating habits, then I will sympathize with people who have to buy extra airline seats to accommodate their girth.
