Not helpful? Hmmmm...well lets try this:
I'm 187CM, 120KG, 12-15%BF. Been training for years.
Previous use with insulin, i prefer pre workout, but had concerns with this diet and fat timings being too close to training time to run insulin pre training.
Goals - At the moment i'm leaning up a bit, but looking at this diet scientifically it should be able to add mass and lean up by adjusting calories from fat.
I understand the dextrose will create an insulin spike without exo insulin, but would have used it to enhance the nutrient shuffle into the muscle post training.
PWO carbs will be vital for performnce the next day given the reduced amount of carbs being consumed, but i've modified the carb cycling approach a little bit to include pre workout insulin or post workout high GI carbs if not using insulin.
0600-carb/protein meal for glycogen reload following sleeping. I've split the high GI carbs up from the low gi and protein as protein seems to slow absorbtion (Having fruit for liver glycogen refill)
0900 fats/protein, broccoli
1200 Carb/preotein meal (Low GI)
1500 fats/protein, broccoli
1830 Insulin-Novorapid 10iu
1835 -2000 Train with peri workout drink BCAA, VIT C, dextrose (50g) consumed over the workout period to reload glycogen in the muscle while transporting nutrients. I have found this to be more effective than carbs periworkout for fat loss and performance.
2000 protein shake, chicken breast
2200 fats/protein , broccoli
On another note, have you tried metformin. Increases insulin sensitivity, etc. Looks like if used carefully may enhance the use of insulin. Also increase the risk of a hypo, but there looks like there is potential.
Generally looks like a good addition to most carb meals in general and bad insulin sensitivity can cause health issues.
