There are so many factors that come into play regarding individual weight loss success.
Have you visited our forum reading posts, checking profiles of posters that have reached goal or just hoping to receive all your answers from what folks post in response to this question?? You'll find that pace of weight loss can vary greatly.
Some factors would be
1- starting BMI
4- conditions like thyriod trouble, PCOS
5- medications being taken (antidepressants)
6- Last but not least.... One's personal committment to WORK their sleeve, following rules like protein first, being watchful of simple carb intake, drinking all your water, taking your supplements (not required actually), moving your body, etc etc etc.
I'm a 41 year old female with starting BMI near 46. I lost 17 lbs pre op, 14 my first full month, 12 lbs months 2 and 3, etc etc etc. Now I'm down 112 lbs and my one year surgiversary is in about 3 weeks. I did not exercise until maybe 3 month ago with the exception of occasional walks, but I did religiously chart my intake, keep my calories reasonable, push protein first, and avoided simple carbs like the plague. You can have weight loss stalls... so I would be careful to not have your single measure for chosing be "how much a month can you lose".
It's not a sprint though.... it's a marathon.... and so is maintenance for that matter.
One can graze all day after having this surgery and not lose an ounce. It does significantly reduce real physical hunger, but not your mental hunger (that's your work to do) and you will feel satisfied on 4-6 oz of food (less initially) when the stomach swelling goes down. You will not have to worry about serious vitamin deficiencies or the inability to absorb important medications. Nice huh....
Significantly less health risk associated with the performing of the actual surgical procedure, less health risks post operatively due to lack of mal-absorption. I would carefully weigh your options.Good luck to you!!! Many have lost all their excess weight and are keeping it off.
Goal weight reached ~ without malabsorption!!! Yipee.....
