I have lost 40+ pounds a few years ago with a meal replacement shake and exercising everyday for several months. The problem is I didn't know the reason why I lost the weight. Was it the diet, the exercise, or both?

Replacing an unhealthy meal with a meal replacement shake is a smart move. Obviously, replacing an unhealthy meal with a healthy one makes even more sense, but some people don't have cooking skills or simply don't have time to make a healthy meal after a long day of working.

The question here is if you can really lose weight by just replacing one meal per day? When I stopped exercising, I stopped losing weight.

I tried a program where you would have a meal replacement shake for 2 meals per day plus you would have to "detox" where you starve yourself one day per week. That was not fun.
