I would add to this list, cardio and weights... I think it's important to do both. Not to mention, when taking something for weight loss, I think some people tend to rely heavily on the meds themselves and tend to overlook the need for exercise and building muscle.. Additionally, if you can build more muscle, then your body will burn more fat (even when at rest)... Also, if a med is giving you dry mouth, I suspect it's dehydrating you , which leads me to.. drink more water..
It's one thing to get the physical on track, but it's equally important to get the emotional/mental on track... don't depend on a pill to change your mindset... as long as the reasons that you became heavy are still in place, no pill will ever really help and if it does, most of the time, it's only temporary...
in the end, diet and exercise are the way to go..
my best to you and yours
