In order to see a result similar to the third picture of another patient, you need to do all three things. Lose some weight, have a complete tummy tuck and liposuction the flanks (love handles).
Losing weight will help flatten your tummy even more than just a tummy tuck because some of your excess weight is on the inside of the belly (this is called intestinal or visceral fat).
The best way to lose weight? Low carb diet avoiding also sugar and processed foods. You seem to have enough loose skin that liposuction will just not get you as tight as the picture of the girl in the white pants.
Remember, however, I am basing this on your pictures as a complete exam may change the recommendations. (Robert J. Spies, MD, Paradise Valley Plastic Surgeon)
5 liter liposuction to the abdomen, sides, and back may produce a great result by itself. (Kenneth B. Hughes, MD, Los Angeles Plastic Surgeon)
You should always try to attain your goal weight prior to any body contouring surgery. (Earl Stephenson, Jr., MD, DDS, Atlanta Plastic Surgeon)
Unfortunately without an examination it is impossible to give advice (Frederic H. Corbin, MD, Brea Plastic Surgeon)
In my experience the best candidates are the patients who have lost all of the weight they need and have been at that weight for at least a few months. At that time, you can go in for a tummy tuck and muscle repair, if needed, to achieve your desired flat tummy.
I would do liposuction on you as well if you still had some extra fat. If you just have liposuction now, you will not have the flat tight stomach that you want. Furthermore, if you just have a tummy tuck at this point and then decide to lose weight, you will most likely have loose skin on your tummy again.
And you would have wasted a lot of money. Do it right the first time. Lose weight, consult with a board certified plastic surgeon and then have your surgeries! (Jaime S. Schwartz, MD, Beverly Hills Plastic Surgeon)
The combination of losing weight and getting a tummy tuck will give you the best result. You will need some liposuction as well, even with weight loss. (Shim Ching, MD, Honolulu Plastic Surgeon)
Based on your photographs and your desired result you will need to lose a significant amount of weight so that there is minimal fat beneath the skin and the skin is sagging. At that point a tummy tuck can be done to tighten the skin.
If you have a tummy tuck without losing the fat beneath your skin you will not achieve the look that you want. Another option would be to have liposuction first follow-up in 6 months by a tummy tuck. Please see a board certified plastic surgeon. (Brooke R. Seckel, MD, FACS, Boston Plastic Surgeon)
You are a perfect candidate for a Tummy Tuck in order to get rid o the saggy skin on your abdomen (which is seen while you are sitting or bending over) and the combination with Muscle Repair in order to achieve a flat abdomen and mainly a small tapered waist.
Liposuction will help to enhance even more the result of the Tummy Tuck, specially your back, lovehandle area and use that fat to be transferred into your butt and hips to create a more curvaceous body shape. Just liposuction will let you abdomen with more flaccid skin and the muscle will remain as loose as is now. (Laura Carmina Cardenas, MD, Mexico Plastic Surgeon)
You are a candidate for liposuction of some areas but for a completely flat stomach you will need a tummy tuck and you will need to establish your best possible weight.
Why not lose weight first and become an ideal candidate. At present liposuction alone would not give you a completely flat stomach and you would have some rippled skin in addition.
Lose weight to ideal and then have the TT and indicated liposuction. (George Commons, MD, Palo Alto Plastic Surgeon)
