  1. As I've already explained in the following earlier post, that graph doesn't show what you think/want it to: http://www.uk-muscle.co.uk/topic/299645-7-day-water-fast-log-challenge-hellish-hence-why-its-a-challenge/?do=findComment&comment=5677141
  2. I'm really not the best person to comment to be honest. I'd suggest doing some research specifically on training for women - my earlier comment is pretty much all I know I'm afraid. I've seen @Dark sim post about coaching women in the past so if he happened to have time to comment he'd be a better bet for you. It would be helpful if you say a little about your GF's goals and training history.
  3. Why not post it publicly? I'll only do this myself when talking about it...
  4. @Dark_Ansem are you going to be able to point me to the data that compares the effect of fasting on metabolic rate with other diets? I see the graph you posted above showed a small increase over the first few days of a fast but I've never actually seen equivalent data for other diets to know what to make of this.
  5. The part in bold I know absolutely nothing about BTW. I'm vaguely aware of general evidence for occasional fasting having health benefits but I've never looked further into this. So to be clear I am saying nothing one way or the other in relation to these aspects, or indeed whether they might actually make what you're doing in some sense a sensible plan. I honestly don't know.
  6. None of those pictures compare metabolic rate between diets, which was the link I asked you to post for me? Unfortunately book references aren't as useful as those of the original research, since it's harder for others to track down. Also it's worth being a little more careful of data published in books rather than peer-reviewed journals, since books aren't peer reviewed. The top graph makes me think of something else that I'll mention in passing though. The graph shows ~50g per day of protein loss after 3 days. The earlier study of yours I've commented on showed a loss of ~1.5g/kg of bodyweight per day. The meat we eat has ballpark 25g of protein per 100g, and although I don't know the actual figure for human muscle it's bound to be similar. So although 50g of protein per day doesn't sound like very much, this corresponds to the protein content of something like 200g of muscle, and if you look at say 200g of chicken breast you'll see this is quite a lot. Remember we're talking per day here. Now I'm not saying 100% of the protein lost will come from skeletal muscle, and I don't really have any good idea what the proportion might be, but it would be misleading to conclude that the graph suggests little muscle would be lost.
  7. You're confusing geography with race .
  8. Concluding that whatever diet leads to the highest levels of growth hormone will be the most muscle sparing, is, I'm afraid, nonsense. That would be like me arguing whichever has the highest levels of cortisol would be the worst because cortisol is catabolic. Neither would necessarily be correct. There is a complex interaction of factors at play. In terms of taking amino-acids to help preserve muscle, yes, this is probably a step in the right direction. But again I would encourage you to switch to a PSMF so you are doing your best to preserve muscle. Please post a link to the specific study that lead you to conclude the following and I'll look at it again (I am not going to spend my time wading through all you links again): I want to understand to what extent this statement might be true, and if so under what exact circumstances. Whatever this surgery is may have a impact on this whole discussion. I'm not asking for personal details here, just making an observation. Also if your primary motivation is purely to lose as much fat a possible before this then I can see why muscle loss may be less of a concern to you. I'd still personally switch to a PSMF though. I'm posting now primarily as you somehow feel all you've had is abuse. I'm trying to explain as clearly as I can where you have misinterpreted study data to lead you to conclude your particular course of action is a good idea. It doesn't bother me if you carry on just to see what happens, but it is your suggestion that what you are doing is somehow evidence based that is misguided. You have constructed what appears to you to be a logical argument to show that what you're doing is sensible, but unfortunately your steps in reaching this conclusion really don't stack up. If they did I'd say so, and would be very interested in them. (I've also partly posted to make this point clear to others who may be reading this.)
  9. Let me clarify then. The reason I am suggesting to you that what you are doing is not a a good idea is because I fear you are unnecessarily risking muscle loss. I believe this is @Pscarb's concern too. Keto diets are not magically muscle sparing when compared to other high protein hypocaloric diets. If there is an advantage it is small. Furthermore I'm talking about regular keto diets here - muscle preservation when in ketosis achieved by fasting is a totally different situation. One for which the study measuring the rates of protein loss in this condition is again relevant. You may feel you have so little muscle that you aren't concerned about losing a bit if you can lose a significant amount of fat at the same time. You have though written about feeling you'd gained some muscle for the first time in your life and so I thought you would probably like to be preserving this if you can. As has already been mentioned in this thread the concerns over muscle loss from a conventional high protein hypocaloric diet are generally signficantly overestimated, especially for someone at your current body fat level. You may even be in a position where you could even gain muscle whilst losing fat for a while. Which of your studies shows this to be true? Not that metabolic rate is an important factor for just a single week diet, and a comparison to a 'very restrictive calorie deficit' may ultimately be rather less relevant than a comparison to a more normal, 'sensible' dieting approach. Have you looked at a PSMF? This is the most widely known approach that will achieve most of what you want but with likely significantly less muscle loss that what you're doing.
  10. My natural walking pace is a bit over 4 miles per hour, although I do have longer legs than most. Now I've never walked as far as 24 miles but I think this helps put some of the slower times into some perspective. I'm not meaning to knock people's achievements/dedication with this comment but the concept of 'running' a marathon can be pushed too far.
  11. It depends how much time she wants to spend in the gym... I'd be tempted to try U/L/U/L for the four days. Bear in in women can generally train with more volume than men and still recover/grow. If your GF just matches your sets/reps she'll likely be holding herself back, especially for leg work.
  12. One study is very relevant - the one which I explained above demonstrated significant rates of protein loss over a seven day fast. This post in fact: http://www.uk-muscle.co.uk/topic/299645-7-day-water-fast-log-challenge-hellish-hence-why-its-a-challenge/?do=findComment&comment=5675693 Your basic premise is that fasting is more muscle sparing than other approaches. None of the studies you linked to make a comparison of this nature and so it is impossible for you to draw that conclusion. I've not spent time reading them all fully but I think at best what they do is show that fasting is not quite as bad as we might expect. The limited duration of most of the studies is also hugely significant. Just post the links but unless they provide data comparing rates of muscle loss for fasting vs a high protein hypocaloric diet I'm afraid they really aren't going to be able to prove what you want.
  13. Please read my posts again if you truly believe this.
  14. I'm telling you that the advice being offered to you in this thread has nothing to do with what makes anyone money. Also large amounts (most?) of fat loss research is publically funded, to try and help tackle the huge individual and societal problems caused by obesity.
