How to Get Rid of Pannus(fannypack)?

It’s difficult to make a specific recommendation without a
physical examination or pictures. Your history suggest the presence of a
significant lower abdominal roll that extends posteriorly into your flanks. In
my experience exercise and diet often make loose skin more noticeable.Although
it’s important to continue weight loss, this probably won’t affect your loose
hanging skin. Under these circumstances, an abdominoplasty will probably be
necessary.For
these reasons, consultation with a board certified plastic surgeon is
appropriate. This surgeon should be able to formulate a plan that addresses
your concerns.

A picture may be helpful in answering your question. You sound determined to reach your goals. It is difficult to predict what your result will be post-weight loss. Many of my weight loss patients reach their ideal weight but are left with loose skin that cannot be removed without surgery. You described stretchmarks, meaning that the quality of your skin is such that it may not be able to “bounce back” after weight loss. Surgery may be necessary.

On this site, I do my best to give advice without a physical examination but I want you to know that a physical examination by a board certified physician is always the best way to get the most accurate information.

After you reach your ideal weight, you can consider trying a serires of non-invasive techniques such as Zeltiq, which uses cold therapy to to freeze fat cells, but you will not get the results you will with abdominoplasty surgery.  Even if you do have a reduction in fat, it sounds like skin excess is also a problem - which responds best to a surgical excision.  Tummy tucks are very common procedures, have an excellent safety record, and patients are usually thrilled with the results!  Consultation with a plastic surgeon will help answer questions and make recommendations based on your body.
