+ 21 "Force Feeding" concept: How to accelerate protein synthesis post-workout
Protein synthesis... who on this site doesn't know this term? Hardly none... AAS's lend us a hand in accerlerating this process, no doubt. But as I hope you know, the gains are made in the kitchen not the gym. So, I want to give a different spin on this process as it relates to nutritional timing so that people can better understand this process and harness its full potential.
In each training manual published by the National Federation of Professional Trainers (NFPT), there is a concept known as the “force feeding concept” that will jumpstart your muscles' anabolic processes. All it takes is some fast-digesting protein such as whey protein, some fast-digesting carbs such as honey or sugar, and some form of light cardio after you hit the weights. Before I explain the application of this concept, allow me to give a brief explanation of the various processes that are affected inside the body so that you will understand why each step is so important.
Our body’s desired source of energy is carbohydrates. All of the carbs that we ingest are digested and broken down into a form of sugar, known as glucose, which is then released into the bloodstream to be used for energy purposes or to be stored for later use. Our bloodstream, however, only has the capacity to sustain a glucose level of approximately 20-25 g, which is 80-100 calories worth of carbs. Once this limit has been surpassed, the body responds by releasing the hormone insulin to regulate the increasing level of blood glucose.
Insulin’s primary function is to make blood glucose accessible to the body’s cells. There are three places that glucose can be stored. The first is inside the muscle. The second is inside the liver. The third is inside body fat. However, when glucose is stored in the fat cells, it’s stored as fat rather than as a form of carbohydrates.
Every cell in our body has what’s known as receptor sites. These receptor sites act as doorways that allow for the passage of certain molecules, but these doorways, so to speak, must be ‘unlocked’ in order for them to open. Insulin holds the key to the receptor sites located on the muscle cells, the liver cells, and the fat cells allowing for the uptake of cirulating glucose molecules.
Ideally, regardless of your fitness goals, you should strive to promote muscle growth while disallowing the accumulation of body fat. Now that we know what happens with the carbs that we consume, how can we control these processes so that we avoid storing them up in the fat cells? It’s actually very simple.
We now know that insulin is charged with the task of delivering blood glucose to the muscle, liver, and fat cells. The thing about the fat cells, though, is that they cannot release and store energy (glucose) at the same time. To avoid the storage of body fat while insulin is present, simply perform some type of light cardio for 15-20 minutes. During this time period, your metabolism will switch to a predominately fat-burning state.
When you lift weights, your muscles are expending the glucose that has been stored within the muscle’s cells. At the end of your workout, those stores are mostly depleted. This causes the receptor sites on the muscle’s cells to open up and allow for the uptake of glucose to replace the energy that has been expended. Insulin will actually bind to these receptor sites, making blood glucose more accessible to the muscles when they need it the most.
When we lift weights, we are actually tearing down our muscle fibers to the extent that they must be repaired. This repair process uses proteins to rebuild the broken-down muscle tissues, resulting in a larger and stronger muscle. However, this repair process does not begin immediately. After a strength training session, the muscle’s number one priority is to replace the energy that it expended during the training session. Until that priority has been met, the muscle-building processes will not take place.
That’s where your diet comes into play. This force feeding concept is designed to speed up these processes, so that you can tap into your body’s natural ability to build muscle much quicker, resulting in faster recovery and greater gains.
Now let’s take this information and put it into practical use.
Before your workout, prepare a protein shake that consists of at least 60 grams of fast-digesting protein and 60 grams of fast-digesting carbs (I like a 2:1 ratio). I prefer to use honey for the carbs because it contains some B vitamins, which are essential for energy metabolism, and I prefer to use whey protein because it digests very quickly. Depending on the bees, honey contains approximately 17 grams of simple sugars per tablespoon. It only takes 20-25 grams of fast-digesting carbs to stimulate the release of insulin; therefore, you want to provide slightly more than that to reap the benefits of force feeding.
Once you complete your weight-lifting session, drink the shake that you prepared beforehand. Then perform some type of light cardio for approximately 15-20 minutes; i.e, brisk walking or slow jogging. Nothing too intense because you want to initiate the oxidative, or aerobic, pathways to stimulate the fat cells to begin releasing their stored energy.
By the time insulin has begun to do its job, the fat cells will already be releasing their energy. This means that all the insulin-carried glucose has only two places to go: the muscle and the liver. Since you've mostly depleted your muscle glycogen stores during your workout, their cells will take up the majority of the insulin-carried glucose. This glucose will be used to meet the first priority of energy replacement.
The second priority in line is called protein synthesis (repairing/rebuilding muscle tissue). Because we chose to use a fast-digesting protein, such as whey, the protein entered the bloodstream at about the same time the glucose did, which means that it will be injected into the muscles’ cells almost immediately. You are literally ‘force feeding’ your muscles at this point.
If you were to consume a traditional meal after your workout, no matter how healthy that meal is, it will take some time for your digestive system to breakdown and absorb the solid foods. You have about a 60-90 minute window to replace the energy spent during your workout before your body begins to feed off itself (catabolism). By following the recommendations in this post, you’re consuming fast-digesting nutrients and you’re timing them perfectly so that you initiate the recovery and repair processes almost immediately.
Remember, no matter what your fitness goals are, always strive to improve your performance. The faster you recover, the stronger you become. The stronger you become, the more you can push yourself. The more you can push yourself, the better your performance.

Bro great post I know I am a couple of years late but have been doing at least 2 hours of research a night thank you for this honestly
Dang this is a good post. Definitely worth a bump. I was going to write something about nutrient timing but you have covered all of the bases here. People need to realize this concept or they are not going to maximize their gains.
Chaz32621Wow what a great read very interesting. Science and bodybuilding best two things to combine.
AnonAnother great write up! Also another one added to my favorites! +1 to you good sir!:-)
SpyVSome awesome broscience here. Seriously though, meal timing has already been debunked. And MPS cannot be extended or optimized by meal protocols. I appreciate the effort and the thought that went into this write-up, but bodybuilding and the fitness industry and those who are proponents of it need to start doing their research.
AnonHow the hell do you get that this is Broscience? If you think this is Broscience then you don't need to be doing AAS. There is more Broscience in AAS than in actual nutrition. The information that is provided above has been proved by scientific studies. Please take the time to do a write up prove to us and the rest of the community to where Dossier is wrong. I doubt you will be able to do that. Good luck trying though.
SpyVThat is a logical fallacy my friend. The burden of proof is on you to prove your argument, not for me to disprove it. But, again, to each their own.
Lmao! Bro science?? You've lost your mind, brother!
This was a paper that I wrote while still in college and working towards my CPT cert. this is also a sports nutrition principle taught by the NFPT. those are facts derived from textbooks my friend. Nothing that I write in here consists of "bro science". Everything I write either comes from facts derived from a textbook or medical journals.
Seems you need to research my friend. Contrary to your beliefs, there is a science behind the subjects involved in health and human performance.
SpyVI'm fine with doing more research Dossier31. Regardless, you have given your position but as of yet have yet to provide proof of the facts.
The premise of your post was a How-to on accelerating MPS, and yet no where in the following paragraph's do you explain the acceleration of MPS. You merely make the supposition that a fast acting protein COULD be timed to coincide muscle glycogen replacement and MPS. But again, MPS in a non-enhanced athlete occurs in a 24-48 hour window. It is on-going in that time frame, it is not immediately happening post workout.
And once again I'll bring back the point of meal timing being largely irrelevant. Whole food proteins can take up to 48 hours to be fully absorbed, so at almost any point in the day or night a well fed athlete will have proteins available to by put to use by the body.
I'm not arguing that a post-workout shake is not beneficial, only that your reasons or assumptions are just inaccurate.
Perhaps I clarified my statement a bit better this time?
You’re picking out pieces of this thread to pose your arguments from. While you are being factual in what you're saying, you're argument is not being kept within the context of this topic.
I’m not some gym rat that reads magazines and listens to the big dude at the gym, brother. I put in my work academically to gain a rather extensive understanding and working knowledge of the subjects revolving around health and human performance. My education is at a college level, and "bro science" is not something that I part take in much. After switching from health and human performance degree to business degree, I not only acquired sports nutritionist and personal trainer's certifications, but I taught the curriculum for the NFPT's CPT certification at a rec facility. I deal in facts, my friend, not bro science.
You’re correct: whole foods take time to digest and enter the blood stream. I am not talking about meal timing in the sense of eating a meal. I am talking about liquid food products comprised of fast digesting proteins and carbs.
The process of glycogen replacement itself does not affect protein synthesis. The goal of this article was for the average minded person to be able to comprehend and understand the key points. If you want me to get into further detail, I can do that.
During strenuous physical activity, muscle glycogen will be used for the synthesis of ATP. For glycogen to undergo this change, a series of chemical reactions must take place at a cellular level. It is enzymes and co-enzymes that are responsible for facilitating these chemical reactions, and they are referred to as cellular catalysts.
Cellular catalysts are responsible for performing all cellular work, including the breakdown of nutrients for energy or for repairing tissue, and their rate of depletion is directly related to the amount and duration of cellular work performed. Without catalysts, the muscle fiber would not function. For this reason, catalyst replenishment takes precedence over protein synthesis. Once catalysts have been replenished, the next basic cellular function can be performed (protein synthesis).
These catalysts are made primarily from the amino acids leucine, isoleucine, and valine (BCAAs). Since muscle tissue is comprised of approximately 60% of these amino acids, if blood proteins (i.e., dietary or otherwise) are insufficient for the replenishment of cellular catalysts, muscle tissue becomes the primary source; thereby, resulting in tissue breakdown.
It is this reason why "meal timing" is so important. Nutrients must be made available to the recovering cells in order to prevent tissue breakdown and allow for the repair process to begin. This is a physiological fact!
The purpose of choosing fast digesting carbs in conjunction with the proteins is to provide for both a quick release and delivery to the cells. because adipose tissues cannot release and store energy simultaneously, the low level cardio benefits us by stimulating the release of fatty acids so as to disallow the insulin-carried glucose from being stored as fat. Once again, this is a physiological fact, not "bro science".
because insulin binds to and opens up the receptors on the cells, having nutrients present in the blood stream at this moment is important to ensure that some of the BCAA's within the proteins can be used for replenishment of cellular catalysts, while the remainder can contribute to the current amino acid pool for the construction of new actin and myosin proteins as part of the repair process.
Having the glucose present allows for glycogen replenishment simultaneously, yes. But the objective was to get a post-workout insulin spike for nutrient delivery. Why do you think bodybuilders love insulin? It has many benefits for us here, and this is one of them. Your pancreas will produce all the insulin you want, with the right stimulus.
How’s that for bro science??
SpyVThanks Dossier31 for taking the time to elaborate on your position.
Let me clarify that my position is not based on anything I have done or achieved on my own. Far from it, I'm purely relying on the information gathered and analysed by researchers at the forefront in exercise physiology.
My point of contention with your well written argument resides primarily with this statement,
"The purpose of choosing fast digesting carbs in conjunction with the proteins is to provide for both a quick release and delivery to the cells."
and,
"Having the glucose present allows for glycogen replenishment simultaneously, yes. But the objective was to get a post-workout insulin spike for nutrient delivery."
Before I address that, let me be clear that I am not arguing against the physiological need and requirement for adequate available nutrients post resistance training. On the contrary, I quite agree with that - and if for no better reason that data supports that, as well as results.
The methodology for achieving it is situation dependent, as factors such as pre-workout consumption, fasted training, etc all have documented impacts on this.
So back to the points of contention. To quote a small piece of a great article that only recently saw publication,
"Even more so than with protein, carbohydrate dosage and timing relative to resistance training is a gray area lacking cohesive data to form concrete recommendations. It is tempting to recommend pre- and post-exercise carbohydrate doses that at least match or exceed the amounts of protein consumed in these meals. However, carbohydrate availability during and after exercise is of greater concern for endurance as opposed to strength or hypertrophy goals. Furthermore, the importance of co-ingesting post-exercise protein and carbohydrate has recently been challenged by studies examining the early recovery period, particularly when sufficient protein is provided. Koopman et al [52] found that after full-body resistance training, adding carbohydrate (0.15, or 0.6 g/kg/hr) to amply dosed casein hydrolysate (0.3 g/kg/hr) did not increase whole body protein balance during a 6-hour post-exercise recovery period compared to the protein-only treatment. Subsequently, Staples et al [53] reported that after lower-body resistance exercise (leg extensions), the increase in post-exercise muscle protein balance from ingesting 25 g whey isolate was not improved by an additional 50 g maltodextrin during a 3-hour recovery period. For the goal of maximizing rates of muscle gain, these findings support the broader objective of meeting total daily carbohydrate need instead of specifically timing its constituent doses. Collectively, these data indicate an increased potential for dietary flexibility while maintaining the pursuit of optimal timing."
Please further review the article at length, it can be found here; http://www.jissn.com/content/10/1/5
At the heart of what I feel your position to be is that carbs are necessary to jump-start an insulin response, and that is not true, and has been clearly demonstrated to not be true.
In the end, its only "Bro Science" when an inaccuracy is being perpetuated. Your advice isn't going to hurt anyone, but nor is it going to be the make or break in any individuals training regime.
No where in this excerpt of yours is the word insulin even brought up. They talk about protein balance in terms of meal timing as well as with ingesting of carbs. Do you even know how protein balance is measured? By measuring the amount of nitrogen in the urine. If the amount of nitrogen exceeds that of what was ingested, then the body is not using the ingested proteins to synthesize body proteins. Instead, they are being deaminated and used for energy purposes.
This has nothing to do with what I am demonstrating here. You're going a bit far to argue with years of medical and scientific data and call it bro science. Lol. Insulin is secreted in response to blood glucose levels. That's a physiological fact that is only an exception with insulin-dependent individuals.
You're obviously an intelligent guy, but you are incorrect. I'm not gonna continue to argue with you either. We can agree to disagree. Have a good one
SpyVAh yes, I forgot to add this study:
http://www.ncbi.nlm.nih.gov/pubmed/17413098 <-specifically address insulin. To quote the conclusion, "A mixture of leucine, isoleucine, valine, lysine, and threonine resulted in glycemic and insulinemic responses closely mimicking those seen after whey ingestion in the absence of an additional effect of GIP and glucagon-like peptide 1."
However in the article I did post there is an entire subsection dedicated to glycogen repletion, an excerpt here,
"Despite a sound theoretical basis, the practical significance of expeditiously repleting glycogen stores remains dubious. Without question, expediting glycogen resynthesis is important for a narrow subset of endurance sports where the duration between glycogen-depleting events is limited to less than approximately 8 hours [31]. Similar benefits could potentially be obtained by those who perform two-a-day split resistance training bouts (i.e. morning and evening) provided the same muscles will be worked during the respective sessions. However, for goals that are not specifically focused on the performance of multiple exercise bouts in the same day, the urgency of glycogen resynthesis is greatly diminished. High-intensity resistance training with moderate volume (6-9 sets per muscle group) has only been shown to reduce glycogen stores by 36-39% [8,32]. Certain athletes are prone to performing significantly more volume than this (i.e., competitive bodybuilders), but increased volume typically accompanies decreased frequency. For example, training a muscle group with 16-20 sets in a single session is done roughly once per week, whereas routines with 8-10 sets are done twice per week. In scenarios of higher volume and frequency of resistance training, incomplete resynthesis of pre-training glycogen levels would not be a concern aside from the far-fetched scenario where exhaustive training bouts of the same muscles occur after recovery intervals shorter than 24 hours. However, even in the event of complete glycogen depletion, replenishment to pre-training levels occurs well-within this timeframe, regardless of a significantly delayed post-exercise carbohydrate intake. For example, Parkin et al [33] compared the immediate post-exercise ingestion of 5 high-glycemic carbohydrate meals with a 2-hour wait before beginning the recovery feedings. No significant between-group differences were seen in glycogen levels at 8 hours and 24 hours post-exercise. In further support of this point, Fox et al. [34] saw no significant reduction in glycogen content 24 hours after depletion despite adding 165 g fat collectively to the post-exercise recovery meals and thus removing any potential advantage of high-glycemic conditions."
I'm going a bit far to argue with perpetuating myths. The fitness community as a whole has come to accept that timing carbs post workout is irrelevant, I don't know why bodybuilding and steroid use forums are still so resistant to these concepts - worse, are hostile when presented with supportive evidence against commonly held custom and beliefs.
As you say, you are not interested in arguing the facts anymore - that is absolutely your decision. But I strongly feel that the audience you are instructing deserve to at the least evaluate the latest data and come to their own conclusions.
Once again: this is good but out of context. Your study talks about the insulintropic effects of whey, not the insulin response to carbohydrates - which is what I am expounding on here. You further go on and on about glycogen replenishment. Once again: I am expounding on the insulin response to the muscles cells via a nutritional stimulus.
I applaud you for standing up for what you believe. If you are on the brink of proving years of scientific data incorrect, I look forward to reading your articles in the news o separate from this. What you've posted is a great find, and I appreciate the input. However, it has yet to address or even show anything to the contrary of the key points in my original post.
Have a good day, sir!
AnonAnother pencil whip?!;-)
I like his style. But he and I will just have to agree to disagree on this one.
SpyVAgreed, and I'll just have to get over not being able to convince you. Don't think I don't respect your opinion or knowledge, I just feel strongly on this matter. In any case, look forward to reading and hearing more from you in the future.
No doubt brother. I appreciate the debate. Fr sent
Solid. I have been using whey isolate snd carbonix post session. Seems to replenish me fast.
Good deal. Throw in enough sugars for that post workout insulin spike and kick that process into overdrive.
awesome thanks
thx doss u can never read good info enough!
