1. Like Kiefer says both in the book and in his articles, tGLUT is also translocated by insulin. This happens in both muscle and fat. Non-insulin mediated translocation happens when you resistance train, and only in the muscles worked that session. You can't flex fat can you? For the exact mechanism you will have to check Kiefers sources. The book has PLENTY. 😛2. We don't know why, but research shows that it does.3. The belief that muscle HAS to be broken down to grow is outdated. Some muscle breakdown is probably inevitable, but you don't always need to take one step back to take two steps forward. You should join the book-owners forum (I think you just click the picture of the book in your profile). There Kiefer can answer questions. It's all in the book however, and it really does have a lot of sources you can check out if you need more details.
