soy protein vvs whey

I am now almost 3 years out and reached my goal. I am also hitting menopause and have been told to up my soy intake. With the onset of menopause plus othe life changes I have gained about 10 pounds in about 6 months..  I want to get back into my protein shakes for breakfast.  Is is okay at this point for me to switch to soy protein instead of whey to help up the soy intake? Will the soy help bolster my weigth loss like the whey did? 

Soy protein, depending on what form, may be absorbed slightly less than whey protein, but in a protein shake should be very comparable to a whey protein shake.  There are, of course, significantly fewer choices of soy based protein powders.

Most of the clinical studies (or reports of the studies) I have seen indicate that increasing soy intake after menopause does little to nothing for various menopausal symptoms, though, so you might want to do some research on that before you jump on the soy bandwagon. There are also some situations (e.g., history of breast cancer or thyroid problems) for which spy intake is generally discouraged.

Also, at 3 years out, is there a reason that you still rely on protein shakes at all?  The only benefit of a protein shake is that you get the protein with a reasonable amount of calories and few carbs (assuming you make good choices in protein powders).  You can do the same thing eating a meal with high protein solid food and low carb sides.

Whey protein shakes did nothing to bolster your weight loss - it is not a miracle diet food!   You lost weight because you had surgery and you would have lost weight if you had never drunk a protein shake (I lost 120lbs in 6 months and never touched one)

Nothing wrong with protein shakes (other than they are often laden with chemicals), but I don't think we should mislead people into thinking they are a super food.

At three years out, it should be perfectly possible for you to eat your protein requirements AND lose your regain ...
