The biggest thing is diet. Without that in check there isn't a program that will achieve your goals. I have lost 48lbs in one year, slowly, by making one 'lifestyle' change at a time, waiting a few weeks/months then removing/adding another. When I was within 10lbs (6 now!) of my goal weight I started restricting my diet more than I would ever maintain, unless trying to lose weight. In other words, I would recommend cleaning up your diet, removing unnecessary carbs was my first step i.e., ice cream, donuts, pizza, soda, etc. Then change the quality/type of food. I guarantee if you do that, you'll make the aesthetic changes you're after.
With all that said, the program is great. I wanted to maintain my strength while continue to cut down and I knew that my schedule would be limiting this month, with family obligations and in-laws in town. This program is only 2 days a week - in the weight room - and hits 4 compound movements a session. Additionally, it's higher volume and has very short rests, which keeps the heart rate up. The only thing I don't do is jump rope, solely because I am too tall to jump rope in my gym and garage without hitting the ceiling. Although, there's finally some nice weather where I live so I might go outside and start. I was substituting jumps/BWsquats/lunges, sprints, or KB swings in its place.
