Not a female, but at 41 and sounds like shes new to the game its going to take some time. Allot of people want to see fast results, but in reality even with AS or other things it still takes time and hardwork. Not saying shes not because 26lbs is allot. I would start by getting her metabolic rate tested to see how much calories she burns resting and then adjust the diet to that. If she does not see good results at that point then maybe entertain that option.
