Spot on, Thib.
Iâve been using a techinque of eating every 4 hours cycle with BCAA in between. I was tyring to set up an improved cyclic approach to the following study by Paddon-Jones et al.
They investigated if combining 30 g of carbohydrate and 15 g of essential amino acids (CAA) altered the metabolic response to a nutritionally mixed meal in healthy, recreationally active male volunteers. Results found that the supplement group experienced 25% greater nitrogen balance than the control group. Further the supplement did not blunt the anabolic response which occurred in a normal meal. These findings suggest that a fast digesting amino acid supplement between meals enhances anabolism throughout the day. These findings also support other studies which indicate that acute increases in protein synthesis are additive in nature to the normal protein synthesis which occurs in a given day
Paddon-Jones D, Sheffield-Moore M, Aarsland A, Wolfe RR, Ferrando AA. Exogenous amino acids stimulate human muscle anabolism without interfering with the response to mixed meal ingestion. Am J Physiol Endocrinology Metab. 2005, 288(4):E761-7.
I use BCAA vs full EAAâs because there should be plenty of substrate left in my system from the meals so as to prevent any rate limiting problems and provide what may be âneededâ by the BCAAâs (particularly leucine) to promote PS.
Iâm 261 lbs and during the weekdays on the AD, Im doing the following with good results:
7am Solid meal 55g Pro, 50g fat
9am 8-10g BCAA (4-5g Leu)
11am Solid meal 55g pro, 40g fat
1pm 8-10g BCAA
etcâŠ
This is an example of an off day. It provides 275 protein, and as I slowly drop my fat grams toward bedtime, about 200g fat. Iâll hit about 40-50g BCAAâs total.
Contrary to what many gurus would suggest, this facilitates gains even at what many would consider an insufficient energy intake for someone my size. Capitalizing on multiple pulses of hyperaminoacidemia coupled with the protein sparing effects of the full meals is a potent way to eat. Iâd also suggest making your last protein meal of the day one that contains at least 20g of casein ( I use 35-40) for the anti-proteolytic benefits.
Best,
DH

The fat cycling made me think of protein cycling, have you experimented with it and if so what were your results?
Actually I have more experience with protein cycling than fat cycling. Long-story short, I believe that short periods of low protein intake can lead to an increase in protein synthesis muscle growth.
I also found that always consuming a super high protein intake eventually lead to stagnation in growth and even muscle loss.
So how do you go about lowering it and for how long and often?
First Iâll give you more details about âwhyâ I see a need to cycle protein.
Two words: blackout and habituation
Habituation is the phenomenon where you get used to an external influence. When habituated, this influence stops being a stress and it no longer leads to a positive adaptation of the body.
It happens with pretty much everything that goes on in our body.
At first increasing protein intake will lead to an increase in protein synthesis (and protein breakdown as well, but ot a lesser extent) which tends to lead to an increase in muscle mass.
If you stay at that level for a while your body gets used to it and it will regulate itself in such a way that the new protein level stops leading to an increase in protein synthesis. The body does so by increasing protein oxydation and degradation.
At that point youâll need to once again increase your proteinn intake , that will spark some new anabolism, but will shortly lead to havituation once again. And this new, even higher intake become enough to maintain only.
And it goes on and on until you need to ingest an idiotic amount or protein simply to avoid muscle breakdown.
A smarter approach is to periodically include low-protein days which will go a long way in preventing habituation, this way your body stay responsive to a high protein intake.
BLACKOUT means that if your body is constantly receiving a trickle of amino acids all day long (as does happen when you consume protein every 2 hours or so, especially from solid food) protein synthesis also decreases, for the same reason as stated above.
ONE OF THE MOST POWERFUL NUTRITIONAL STRATEGY YOU CAN USE TO STIMULATE MUSCLE GROWTH IS GOING FROM TO A STATE OF AMINO ACID DEPLETION TO A SUDDEN SURGE IN BLOOD AMINO ACIDS.
In other words going from a state where there isnât much amino acids in your blood to a state of hyperaminoacidemia will act as a direct signal to initiation protein synthesis/muscle building. And the faster you go from one another, the more powerful the impact will be.
Those peaks called hyperaminoacidemia are directly proportional to the spead of absorption of a protein. So casein hydrolysate is the most effective followed by whey hydrolysate and regular whey. You want as many of these peaks as possible, while tring to avoid having a constant flux of amino acids throughout most of the day.[/quote]
