Q: hello,Mike i had the gastro bypass about one year ago. i lose about 95 poundsbut i'm having problem losing more. my weight goes from 145 to 155 .what do you suggest

A: The biggest challenge you will face after gastic bypass as far as fat-loss is keeping your metabolism up. You will lose a lot of fat (as you have done) and muscle (unfortunately -- it's always a side-effect of rapid fat loss), but after some point your body simply adopts to the low-energy regimen and all your metabolic processes slow down to a crawl. You've probably noticed that you don't have much energy and may sometimes be cold even on a warm day -- these are symptoms of slow metabolism.

For most people the way out of such a metabolic dead-end is slowly increasing number of meals and portion sizes (of healthy foods, of course) till metabolism revs back up. Physical exercise, especially intense exercise such as heavy weight training also helps speed up metabolism a great deal. Once the metabolism is high the fat-burning will continue.

Unfortunately in your case you're very limited in the amounts and types of food that you can eat. You may also be limited in the type of physical activity you can perform and heavy weight training may not be appropriate for you. Unfortunately I am not in any position to make that diagnosis. So here's what I want you to do: read and understand my Fitness Tips -- they're really quite simple. Now with those tips in mind, do couple things. One, consult your dietician to find out what foods and what amounts of them you can safely eat in an effort to get more meals and bigger portion sizes into you in an effort to boost your metabolism. Two, consult your doctor to see whether fairly intense weight training is appropriate for you. If your doctor says yes, then read the Weight Training article and pick from the sample exercise programs that it offers. Two of the programs (no-equipment and dumbbell-only) you can do at your home with minimal or no equipment. Remember that your goal with weight training is to exercise muscles over your entire body, so don't ignore legs or back or any other muscle group. Also remember safety first with weight training -- learn each exercise with light or no weights before you jump to a weight that's heavy for you. If your doctor says no to weight training, then ask him what is the most intense kind of exercising that you can do safely and do that. I hope that helps. Good luck!
