Such as on the website that you mentioned.
Not needed at all to create strict Diet at this stage, or hopefully any, but at least a guide to add more 'good foods, and less of the ones that create the 'spikes and where out insulin and turn into fat cells so quickly.
Not that I think the NY Mayor's 32 oz soda restriction for fast food is a perfect idea by any stretch
(I knew New Yorkers would love being told what to do , lol), but his concept was solid.
I, too, have some issues with finding whole wheat pasta (tried it 3-4 years ago, and it did not go well, lol)
At the very least, if you are having a meal with processed carbs/pasta, if you can also have a portion of a complex carb along with some protein, they interact much better.
That forms the solid building blocks, and all the rest can come later. There have been some amazingly quick turnarounds (like 2-3 weeks or less), for people who have switched to items on low glycemic index,etc. and the resulting lowering of blood sugar counts, as well as other, better indicators.
It's one of these, if they catch it relatively early, Diet alone can make a major influence on recovery
