Hi RICKY De Los Angeles. Thanks for the question. A double-chin is essentially an extra compartment of fat. From my understanding, like other areas of fat in the body, you cannot "spot reduce". But with a combination of a healthy, balanced diet and exercise, you can reduce your overall body fat, which can then help reduce any wobbly bits. You may want to look into Chris Mohr's 21-Day Nutrition program as a good start to a healthy diet. Or you may think about joining a fitness program that focuses on overall body fitness.
