I didn't read the article, but I have been taking whey protein for the past few months regularly since I've been working out heavily. I've also taken in it the past when working out. It's just one of the best protein supplements that your body easily absorbs.
My personal favorite is Solgar Whey to Go (70 cal, <1g fat, 1g carbs, 16g protein). Not because the taste is spectacular or anythings, it's just that their products are really high quality, good and clean/pure... no junk in them.
I have 3 meals a day and 2 snacks... the whey being one of the snacks (after weight training). I believe it's good support for weight loss. I've lost 23 lbs in the last few months and dropped down 8% body fat... from eating clean (incl whey), watching calories, weight training, and cardio. Whey protein wont help anyone lose weight on its own but it will provide excellent support... it's also good for your immunity.
