Thank you for your question. Looking at the photos you have provided it looks like you maybe dealing with some intra abdominal fat, diastasis and some extra skin. I would suggest a tummy tuck. This will allow your Surgeon of choice to tighten up the abdominal wall muscles and pull down the extra skin. Some Surgeons will also do some liposuction on the flank area to help contour the mid section a bit more. A low carb diet and exercise is also good to help reduce the intra abdominal fat. I would suggest seeing a Board Certified Plastic Surgeon in person to evaluate you and discuss your options. Best of luck to you.
You appear to have loose skin, therefore a tummy tuck would be more suitable for you. Liposuction would not be sufficient as it would leave you with loose skin and a “muffin top”.
