Everyone needs to switch to decaf.
There is almost no difference in taste between normal Illy and Illy decaf. If you want something warm in the mornings, then that's it.
I started on my detox today, then I'm switching to a new diet next week. Not that I wasn't eating well, but my new diet is based on numerous blood test and my current fitness, etc. My fitness has been increasing quite steadily and quite quickly the last few weeks. I'm glad I didn't cut down on weights, the combo of cardio and weights do wonders for me.
As to advice, well, that's always going to be hard to come by. Me and my friend have years of reading up on MULTIPLE approaches, trying them, figuring out what works for us, when they work for us, and so on. Nobody ever gave us definitive advice, you have to figure it out yourself. The biggest thing is to get started though. Once that's done, you can try different ones and see which exercises suit you better.
