OK Andrea & Liana (or anyone) one more question

- I've been doing some research on "insulin spikes" - also called carb loads, carb nights, I think the way P4 incorporates is suggesting cheat/treat days. I'm curious what your experience has been.
I don't have much fondness for this concept as I haven't felt in the past like my body does well with any excess etc.
I don't feel like I generally want or need them for mental health/satisfaction type purposes (I could be wrong on that).
However, if there is actual value to the body and health and metabolism, I want to experiment with it.
I definitely have noticed that if I underfeed my body, I will gain weight. I think my body is similar to you both in that it seems quite sensitive in many areas, and I have to watch it pretty closely.
Have you found that it is helpful for you to do a heavier carb night from time time - weekly or otherwise?
Thank you!

p.s. edit later today: since I wrote the above, I also wrote to a friend who many years ago lost about 100 lbs, and since then has become a triathlete, and finished schooling/licensing in nutrition/physical therapy/coaching. He is an awesome resource. Here is his answer to my question above, but would still like to hear your experience ...or anyone else reading this....
"So my experience with the whole cheat meal or my opinion of it is that it's more for people to eat the crazy stuff out there that mainstream society says it's ok to eat. I don't really incorporate anything like that into my diet anymore. I've found that by eating starchy carbs or low glycemic index carbs (Sweet Potatoes, Rice, Broccoli, Cauliflower, Oatmeal) that my insulin stay at lower levels.
Insulin spikes really have to do with sugar though. The more sugar you take in that is easily digestible (soda, candy, processed foods) that don't have any way to counter act (fibrous fuits/veggies, protein sources) the sugar being put directly into the blood system. For non-athletes there really isn't a reason to have a carb loading night. The reason behind those carb loading nights or cycles is to make sure your stored energy (sugars) in the muscles are completely topped off. So if you don't feel you need it, then don't bother with it.
The only time that I'll go heavier carbs is if I have a long training day coming up (60+ Bike Ride or 13+ mile run) and I know I won't have enough time through the day to get proper foods down.
If you're sensitive to sugar though I would just try to cut processed sugars out as much as possible since there is nothing of nutritional value to offset it."
