I would agree with Dr. Jacobs assessment that your result is better at a lower weight. In any case, correction with peripheral liposuction and central fat grafting would be a reasonable approach to take. Using fat flaps as opposed to fat grafting would be slightly more invasive, since this would require reopening your peri-areolar incision, but this would also be reasonable. Fat flaps involve opening the incision and using fatty tissue from around the central depressed area to fill in the depression by mobilizing and suturing them. Fat grafting uses fat removed with liposuction and re-injected into the central depressed area.
Regarding liposuction of the abdomen versus DIET and exercise...The results of liposuction would not be particularly satisfying to you, since liposuction will only remove fat between the skin and underlying muscle. Your abdomen looks to be pretty big and round from the photo, meaning that you have fat on the inside as well as the outside, and the internal or "visceral" fat doesn't go away with liposuction--only with DIET and exercise. Removing the superficial fat will still leave you with a big round belly--it will just have less fat on the outside.
Exercise alone will not alleviate the weight issue without making dietary adjustments, at least not very quickly. Imagine that it takes a 6 mile run to burn off one piece of chocolate cake--so how much exercise alone would it take to burn through what you eat on a daily basis? Quite a lot. You should focus on your caloric intake, such that what you eat daily falls slightly short of your caloric needs. Adding exercise allows you to take in more calories, but you would still need to be in a "caloric deficit"--in other words, you need to be using more calories than you're consuming. Other maneuvers to help lose weight are to divide your meals into smaller meals every 3 to 4 hours, rather than 2 or 3 large meals each day. Also, writing down what you eat is very effective to help with weight loss. The highly guarded secret to weight loss is simple math: what goes in has to be less than what comes out! Even the most adamant fat cannot beat the simple rules of arithmetic. If you have an iPhone or similar device, look for an app called "Lose it" or something similar, which monitors caloric intake and works great for calculating what you eat over the course of the day.
Good luck,
