What are your views on this diet? Which is 5 days of protien and fat (no carbs) and then 2 days of all carbs with very little protein and fat.
Sport anabolic diet?

I like the A diet. Your summary is a bit flawed. Its low carb 5 days with mostly fat and protein. Then for 1-2 days it is higher in carb, while still getting your protein. I did it and dropped 7lbs rather quickly.
That is my experience and results may vary.

perhaps because carbs are very hydrated, and considering you could store up to 1kg of it plus the water, of course you will lose some weight fast.
I think this is what a lot of programes take advantage on, get the client to see the results and hence beleive it is working when its not really valid at all.

Perhaps could be used for anything.
There's a LOT of research on the advantages of low carb diets. This is a ketogenic diet with built-in refeeds. As long as you are able to get in proper amounts of nutrients and fiber, I don't see a problem with it (of course, I'm not clinically trained in nutrition either, so take that for what it's worth).
I used a form of a Ketogentic diet (low carb and carb refeed) to lose that last amount of body fat that was being stubborn even with proper manipulations of calorie deficits and exercise increases. With me it took this form of diet along with a proper deficit and an increase in cardio to get the job done. In my opinion, it has its place in ones diet dependent on their goals and current body composition. I did get bad breath (just like they said is a side effect, and slept alone on the couch a few days 
)

Hahahahahaha...green tea goes a long way, my friend
Any idea what the research says about the efficacy of ' low carb diets ' with respect to gym rats who train and typically use glycogen as a primary source of energy to fuel their exercise - i.e a moderate amount of exercise of weight train, cardio on a regular basis ..... such as 5 days a week ?
I don't *think* that there's been that kind of study performed (there usually isn't, really, because when you deal with experienced lifters it gets difficult to have a "baseline" effect: this is one of the major potential flaws in applying most of the studies performed as an experienced lifter...they're all done on previously sedentary populations, which will respond differently to a treatment than an experienced athlete). However, the idea here would be that if you're interested in performance in the gym or as an athlete in competitive sport, then you're not going to be sacrificing performance with a diet. Anecdotally, many of my clients have seen significant improvements to their strength even while dieting with low carb diets, but again it's likely that these improvements would come faster with greater muscle gain had they been eating more "normally." However, since this was not their focus (just a happy bonus), it isn't an issue.
Thanks for the detailed reply - as always. Much appreciated.
On your point " you're not going to be sacrificing performance with a diet " - in the context of ' low carb ' diets and ketones.
My understanding is that you body breaks down ketones ( into compounds ) to get the energy it needs for day to day activities and some forms of exercise . So, ketones can in fact provide energy to sustain some very low to moderate intensity aerobic activity - i.e I assume oxygen is needed in order for these ketone derived compounds to be utilized.
However, my understanding also is that you can't generate energy anaerobically with ketones. Is this true ? If it is true, given weight lifting and HIIT are ' primarily ' anaerobic in nature, I wouldn't think embracing a ' low carb ' diet while training and doing intense cardio is a good idea...from an athletic anaerobic performance point of view .
So, if ' low carb ' diets seriously diminish your glycogen stores ( the primary fuel for anaerobic exercise ) and ketones can't fuel anaerobic exercise ( assuming this is true ) then can I assume amino acids represent the primary fuel for anaerobic exercise (i.e by means of gluconeogenesis ) in such an anabolic diet regimen ?
Am I viewing the relevance of ketones to anaerobic exercise correctly ?
Welcome your thoughts.

My question was more around ketones ( i.e I should have said ' low carb diet '
) and anaerobic exercise like HIIT and weight lifting. You need oxygen to burn fat and anaerobic exercise is usually done in an enhanced state of oxygen deprivation.Since weight lifting and HIIT are ' primarily ' anaerobic in nature - and as a result, oxygen isn't readily available to burn energy - presumably fat is no longer a viable ' primary ' fuel source for these types of ' primarily ' anaerobic exercises.
And, if glycogen stores become very low on a ' low carb ' diet such that glycogen can no longer be used as a primary fuel for anaerobic exercise, and you can't use fat for anaerobic exercise ( because you need oxygen to burn fat ) , and ketones can't be used for anaerobic exercise ( perhaps bipennate can confirm this for me
)....what fuel is the primary fuel for anaerobic exercise under a ' low carb ' diet regimen ?btw Derwyddon - perhaps you would know.....
.....is it possible to obtain energy anaerobically from ketones ?

I would say no ketones cant be used for glycolysis, they are derived from fatty acids and they cant be transformed into glucose.
Its important to remember there is always a small store of ATP in tissue, but without glucose you will fatigue very quick.
I would imagine protein and fat to some extent as providing some of the glucose in weight lifting etc by conversion to glucose. Which is significantly less efficient and also losed muscle mass.
Dont forget also that fat metablism relies on carbs, without it fat cant be broken down because of a defiency of oxaloactetate, thats why its then converted to ketones or halted in the form of acetyl coa, therefore slowing fat metablism.
but by all means, beleive what you want
