What has been your experience with the obvious ones? People keep bringing them up because by far they are the biggest contributors for most people.

Couple anecdotes from myself: TL;DR - Be on the lookout for patterns.

1) I noticed a pattern when I would go home for the holidays to visit family. I was incredibly drowsy on most days, for most of the day. I would eat all I want, which for breakfast might mean pancakes with loads of syrup or french toast with syrup and maybe there's an egg in there somewhere. If I made an effort to vastly reduce my consumption of high glycemic carbs at breakfast, my energy through the day would be immensely better, like night and day improvement.

2) I was also struggling with fatigue during the day sometimes while not on holiday. I found that it was tied to consumption of artificial sweetener in my coffee in the morning. I often wouldn't eat breakfast and just have coffee and be ok until lunch. But if I had saccharine(sweet n low) in my coffee, I would feel very tired. I stopped drinking coffee like this and haven't had the problem come back. My non-doctor opinion is that because artificial sweetener induces an insulin response in the body, but doesn't contribute to any blood glucose, what blood sugar I had was getting pulled out and placed into fat cells. I will sometimes allow myself sweetener but with a breakfast and be fine.
