It's not just with HIIT, also applies to other forms of exercise.
If I do nothing for two or three days, I see a worsening of control/higher insulin needs.
I maintain that the best thing you can do is a mix of different types of sessions.
What I have found regarding diet for loosing fat is: 40% low to medium carbs, 30% good clean protein, 30% fat mostly omega 3 of good quality olive oil, almonds, avocado etc - the percentages are of calories, To get more detail check out "

For my sixpack to show my fat % has to get below 12% as I carry my bf in my stomach area - I understand people who carry their bf there are the most likely to get t2.
I was diagnosed with t2 in 1999 - I expect I had t2 a good amount of time b4 that. I did not start to get into shape until 2013 - the 40-30-30 diet led to a lot of weight/fat loss (about 38 pounds and from 29% bf to 12%). my wife thought I was too skinny so I added some bf back. I am pretty sure I'm going back to 12% as I like it better there.
Soon after I started regular workouts I began doing "super sets" - do a set for one muscle group and then immediately do a set for another muscle group then rest for 60 seconds and repeat 2 more sets each - I believe that enhanced my fat loss. I also focused on major muscle groups (chest one day, back the next and legs the next - always doing cardio b4 working out and core work at the end. I don't super sets very often now but I still focus on the largest muscle groups to build more muscle weight.
Regarding HIIT and lower bgl 's: I have tested by practicing a 2 minute HIIT workout each morning and measured my bgl's throughout the day with out taking any metformin or novolog flex pen injections my bgl's are so far 40 points lower.
The reason I am doing just 2 minutes HIITs is the doctor in the video I viewed indicated that just 60 seconds of HIIT each morning is all that is needed to get results. His presentation was aimed at t2 diabetics in general (most of whom would not be in very good physical condition).
I am trying to see if this works consistently or fades after some time, or if a problem develops like what Josh Bryant indicates below. What Josh is talking about much longer HIIT workouts - to see Josh's whole article go to bodybuilder.com/HIIIT.
Josh Bryant, MS, CSCS makes the point: "interval training is not without its downfalls, of course. Just because I'm suggesting it to build a lean, mean physique doesn't mean you should incorporate it into your routine on a daily basis. In fact, you shouldn't.
True interval training isn't a rushed jog—it's balls out. The central nervous system (CNS) is primarily affected by this high-intensity work and takes a minimum of 48 hours to recover. The late Canadian sprints coach Charlie Francis described the CNS like a cup of tea—everything pours into the cup until things start to overflow.
Overtraining leads to overflow. If you're overtraining, intervals can tax your CNS and cause muscle damage, mechanical tension, and metabolic stress. Like lifting heavy iron, interval training must be allotted sufficient recovery time."
This may be a lot more about me than you wanted to know.
