Some people are destined to have slim builds while others try to get slim by taking weight loss too far. Because weight alone isn’t the only standard, these behavior changes may indicate greater problems:

• Persistent negative comments about body shape and size.
• Insistence that they are “fat” when they are obviously thin
• Excessive exercise
• Inability to accept compliments; frequent self-belittling comments
• Obsessive fat-gram and calorie counting
• Odd food rituals such as excessive chewing, eating foods in a certain order, rearranging food on plate
• Constant weighing
• Refusal to eat in public or secretive eating habits
• Thinning hair
• Yellow, dry skin or brittle nails
• Complaints of always being cold
• Excessive gum chewing or beverage drinking
