Protein is definitely needed after a resistance/strength training workout, but carbs are also used by the body to build new muscle (not just repair the muscles broken down in the workout, as protein does). I don't know what the recommendation is for women (especially someone who is still losing weight to reach goal post-WLS), but Men's Health magazine recommends that men eat something with 30-40 g protein and 60-80 g carbs (healthy carbs, not simple carbs!) following a strength workout to maximize the muscle building (we're not talking competitive bodybuilders here, just regular men who work out with weights).
When I read that suggestion in Men's Health, which echoed what BodyPump instructors had told me, I thought I'd try it, since my body was still looking more lean than muscular, despite doing resistence work three days per week. I switched from just drinking Syntrax Nectar after BodyPump classes to eating a can of Trader Joe's turkey chili afterwards (yes, I can eat a whole 2-cup can in 20-30 minutes) - it has around 40 g protein and 60 g carbs. Since the switch, I've seen a definite improvement in my muscles - BodyPump builds long, lean (not bulky) muscles, but I'm definitely seeing more development in my chest, shoulders, etc. since I started adding carbs to my post-workout protein intake. This is at a stage, however, in which I want to maintain my weight and add lean muscle - your needs may be quite different at your weight-loss stage and carbs may slow your loss down...
