Probably not. "It's very possible for someone who is fit and toned to be 10 pounds above standard weight recommendations, provided the weight is evenly distributed," says Ann Kearney-Cook, PhD, a psychologist and author of Change Your Mind, Change Your Body (Simon and Schuster, 2004). Excess pounds stored around the midsection can raise heart disease risk even in otherwise lean people.
To check, calculate your waist-to-hip ratio (waist measurement divided by hip measurement). If yours is below 0.85, you're in the clear, says Kearney-Cooke.
