2 hour class and need for weight loss shakes?

hi everyone. from my research there is alot of back and forth regarding if post-recovery shakes are really needed. i generally do 2 back to back classes at my gym of usually kickboxing + zumba or step + zumba and both classes are 1 hour each. when i do the body pump class i usually do this 1 hour class by itself. would i likely need a post recovery shake? i'm lactose intolerant, so i was thinking of either drinking soy chocolate milk or lactaid chocolate milk after the classes. and cheese + apple and peanut butter prior to the classes. any thoughts on this? my goal is to lose inches, lose fat, and lose weight. i usually do body pump twice/week. thanks for any insight.
