This has me very curious! How did you decide on eliminating wheat and sugar? Or did you cycle through various eliminations until you found a combination that worked? And how did you know when to keep going/stop?
I was doing a big job for some hippies, and they fed me lunch every day. And even though I thought it was bullshit, I was polite and ate their gluten free, sugar free, organic, free range, etc, etc food. My entire life I hated eating, but I quickly realized that I really enjoyed eating with them, and I felt really good afterwards.
And since then I've done a lot of experimenting and reading other peoples thoughts, and reached the conclusion that simple carbohydrates are fucking terrible for you, for multiple reasons. The biggest is that it causes an insulin spike. If you're then physically active, you'll burn off the sugar you just ate, but your insulin levels stay high, so you'll never start burning your body fat. You just get hungry and eat more sugar.
