Welcome.

Agreed, alot of training, particularly on what is, essentailly, a zero carb diet.

Legs look great, upper body is a little 'light' in comparison. How is your upper body PT session re: sets and reps? You may benefit from a 3-4 day lifting spit with associated cardio to try and up you lean tissue a little.

And an insulin spike isn't necessary. AT any time.
