A hip dip is a common and naturally occurring depression or indentation on the outside of the upper leg, just below the hip bone. It is common for hip dips to appear as large indentations on the hips for some people. Your hip dips are mostly determined by your genetic skeletal anatomy, and your body’s fat distribution and muscle mass can influence their appearance. Particular factors such as the width of your hips, fat distribution, muscle mass, and distance between your anatomy are significant influences. The shape of your hips and buttocks, as well as the appearance of hip dips, are heavily influenced by these factors. Contrary to popular belief, hip dips are commonly associated with lower body fat stores in these areas, since there is less fat to “fill” the gap. The ability to store fat in this area of the body is highly genetic and hormone-based, so you cannot control it. It is unlikely that building muscle mass in your glutes and gaining fat will completely eliminate hip dips.
