Because a shitty training program and a tightened up diet can lead to better fat loss than a shitty diet and awesome training program.
Interesting that your own progress seems to reflect the importance of addressing diet more than training, as you said:
"I was trying to find ways to do it as quickly as possible. Eventually diet and nutrition needed an overhaul.
Once I cut out excessive sugar and started eating dark green vegetables everyday that I saw notable improvements in body comp and also just overall performance. Not just in the weight room but also every area of my life."
