After Weight Loss, the belly often does not spring back into its original shape. The fat will go away, but skin and the abdominal muscles remain loose and redundant. They are stretched by the excess fat, and over time this over-stretching becomes permanent.
Loose Skin can remain unsightly, and lax muscle allows the abdominal contents to push the belly out. Both these problems rarely respond well to diet and exercise. Loose skin and Over-stretched Muscles cause unsightly bulges. Well after the excess pounds are lost, these continue to effect how we look and feel about our body, even in clothing.
