If you're so healthy, prove it. Weight, measurements, blood work, progress tracking, etc. Put your money where you mouth is.
The benefit or rice cakes or any other specifically selected macro heavy food is nutritional partitioning. I see food as a fuel source or simply building blocks for my body. Sure, it tastes awesome, but you need to select food based on your needs. I wouldn't expect you to understand if the penny hasn't dropped by now.
People sneezing all over food in a food court? What are you talking about? Oh, do you still have your panties in a bunch about my chicken and rice meal? It was a discounted, sealed in a container, surplus, but made a few hours earlier meal from the sushi section in Woolworths. So now you have a problem with chicken and rice as well as supplements? Well which is it?
And please link me to any studies to say that BCAAs (amino acids, you know in all protein) is killing my organs.
You really need to stop your obsession with me and put that attention towards your own health and fitness. If you call what you're doing now "training" for 20 years, I definitely hope I'm not doing that. I train nearly every day; either resistance, riding, hiking, body weight. I eat healthy with a few supplements that help me reach my goals and stay on track, I get outdoors and organise social activities with my friends, I don't feel restricted in my eating, yet maintain a reasonable body fat level without even trying, I never get injured and I even gave competing a crack. I think that's a pretty healthy and balanced relationship with fitness. What have you done in the last 5 years apart from whinge on this forum and criticise people actually achieving their goals?
