Hi Kieran. What do you mean by a "conventional diet"? Can you describe this for me?
Yes, as long as the calories are balanced. You might consider taking a single multivitamin daily to cover any deficiencies that might occur during the period of your restricted diet.
Hi Kieran. I'm not in a position to field a call right now. Would you like to work with another expert?
Yes, of course you can lose enough weight through diet alone. This can be very difficult, however, without an exercise component. You did not get this size overnight, and you cannot undo the weigh overnight. It can take years, and requires a high level of motivation and discipline.
That said, bariatric surgery is becoming more and more common, and many of the risks and complications have been worked out to the point of it being a very safe approach in most individuals. This also requires a fairly high level of motivation and discipline, as well as the psychological fitness to endure the healing process and the process of keeping the weight off.
I have seen many success stories. Your overall health is a very important factor, of course, as is the experience and skill of your surgeons.
