The thing is that a lot of people jump into a program not prepared what to expect, and you can expect adaptations that go from unexpectedly good to unexpectedly bad.
My personal experience with working out hard has always equaled less fat loss that working out less (less volume, less frequency). Weight loss is about being able to happily sustain a lifestyle over a long period of time in order for lasting changes to occur. You can be miserable for a couple of weeks, but then your mind fights you and forces you to regain and feel even more miserable since you thought you were doing the right thing.
Don't do more than the minimum necessary, start off with 3 days a week of both strength (full body) and moderate intensity aerobic training and really focus on your diet and you should be fine. Over time, you can up the intensity and add more days in your weekly schedule. I just cut one of my clients training in half and she's been feeling and looking great. We were able to achieve a deficit of 1000 calories, just because she is not killing herself in the gym and eating like a madwoman at night.
Log what you eat and your training and look at the results you are getting. You are your own lab
