Protein is extremely essential, super satiating and amazingly anabolic. Protein is awesome. Strangely, very few people think it’s a bit too accidental that the optimal amount of protein your body can assimilate in a day is exactly 1g/lb. Of course, I know you read my articles for their scientific merit, so let’s look at the literature on the effects of daily protein intake to find out if 1g/lb really is the optimal amount of protein intake for maximum muscle gains. Studies on the optimal protein intake. All values in the bullet point list below are expressed as grams of protein per pound of body weight per day. All of these studies controlled for energy intake, either based on individual requirements or by setting energy intake to be equal in all experimental conditions, so that only the proportion of protein in the diet varied between groups. If the studies were based on unreliable methods such as nitrogen balance, a marker of lean body mass changes, I only included them if they controlled for sweating and dietary adaptation periods. Protein oxidation did increase in the high protein group, indicating a nutrient overload. The authors suggested that 0. Based on nitrogen balance data, the authors recommended 0. This recommendation often includes a double 9. As such, this is already overdoing it and consuming 1g/lb . The picture below summarizes the literature. As you can see, 1. But I train harder! If you still think you need more than 0. Lemon et al. Well, Tarnopolsky et al. Resistance training causes both breakdown and synthesis to increase, normally with a favorable balance towards synthesis. As you progress in your training, the body becomes more efficient at stopping the breakdown of protein resulting from training. Since less protein now needs to be replenished, this increase in nitrogen retention means less protein is subsequently needed for optimal growth. Secondly, the more advanced you are, the less protein synthesis increases after training. As you become more muscular and you get closer to your genetic limit, less muscle is built after training. This is very intuitive. The slower you can build muscle, the less protein is needed for optimal growth. It wouldn’t make any sense if the body needed more protein to build less muscle, especially considering that the body becomes more efficient at metabolizing protein. But what about when cutting?

A final objection that is often heard is that these values may be true during bulking or maintenance periods, but cutting requires more protein to maintain muscle mass. Walberg et al. The researchers took a group of endurance trained subjects and had them consume either 0. Background material for The House of Dead Maids. New York: Henry Holt, 2010. For those who wish to learn more about the.They also added a thousand calories worth of training on top of their regular exercise. So these guys were literally running on a 1. Talk about a catabolic state. However, the protein intake of 0. Nitrogen balance, whole- body protein turnover and protein synthesis remained unchanged. A further review of the literature on the optimal protein intake in a deficit can be found in this article of the research on protein by Eric Helms. Also, the supposed difference in nitrogen sparing effects of carbs and fat are negligible (Mc. Cargar et al. 1. 98. Millward, 1. 98. 9). Neither actually spares protein though. Only protein spares protein. I think the protein sparing idea came from a wrong interpretation of the nitrogen balance literature showing more lean mass is lost in more severe caloric deficits. A simple explanation for that finding is that the more total mass you lose, the more lean mass you lose. No surprises there. As such, there is simply no empirically substantiated reason to think we need more than 0. If anything, you could reason the body should be able to use more protein during bulking periods, because more muscle is being built and a lot of other nutrients are ingested that may enable more protein to be used. The only people that may actually need more protein than 0. Androgen or growth hormone users definitely fall into this category, but I don’t exclude the possibility that some adolescents do too. If you reach peak testosterone production while still growing (in height), your unusually high levels of growth hormone and testosterone might increase your protein requirements. There’s no research to support it. Those rare individuals with amazing bodybuilding genetics could also qualify, but unless your father happens to be a silverback gorilla, you are most likely just like other humans in this regard. The 1g/lb Myth’s Origin. Why is it then that everybody says you need to consume 1g/lb? Aside from the facts that there don’t need to be any good reasons for why people believe in a myth, that myths tend to perpetuate themselves via conformism and tradition, and that the fitness industry is flooded with myths, here are some plausible grounds for the . Steroids enable you to assimilate far more protein than you’d normally could. There are so many studies showing protein is good for you, it’s hard not to think more of it is even better. There are actually several industry- sponsored studies showing absolutely miraculous benefits of consuming more protein (see for example the studies by Cribb). The excess will simply be used as energy. However, protein sources tend to be expensive compared to other energy sources and variety generally beats monotony with regards to your health, so satiety and food preferences are the only reasons I can think of why somebody would want to overconsume protein. Take Home Messages. This already includes a mark- up, since most research finds no more benefits after 0. Have a look at the Bayesian PT Course. Click here to see the scientific references.

It's typically used to relieve mild or moderate pain, such as headaches, toothache or sprains, and reduce fevers caused by illnesses such as colds and flu. Paracetamol is often recommended as one of the first treatments for pain, as it's safe for most people to take and side effects are rare. This page covers: Types of paracetamol. Who can take it. How to take it. Taking it with other medicines, food and alcohol. Side effects. Overdoses and extra doses. Types of paracetamol. You can buy most types of paracetamol from supermarkets or pharmacies. Some types are only available on prescription. Paracetamol is available as: tablets or caplets capsules liquid – usually for children soluble tablets (tablets that dissolve in water to make a drink) suppositories (capsules inserted into the back passage) an injection given into a vein – normally only used in hospital In some products, such as cold and flu remedies or certain combination painkillers, paracetamol is combined with other ingredients. It may be sold under the name paracetamol, or under various brand names (which may also contain other ingredients). Who can take paracetamol. Most people can take paracetamol safely, including: pregnant women breastfeeding women children over two months of age – lower doses are recommended for young children (see How to take paracetamol below) If you're not sure whether you can take paracetamol, check the leaflet that comes with it or ask your pharmacist or doctor for advice. Always get advice before taking paracetamol if you: Don't take paracetamol if you've had an allergic reaction to it in the past. How to take paracetamol. Make sure you take paracetamol as directed on the label or leaflet, or as instructed by a health professional. How much you can take depends on your age, your weight, the type of paracetamol you're taking and how strong it is. For example: Adults can usually take one or two 5. Children under 1. For very young children, paracetamol liquid is given using a measuring spoon or an oral syringe. Paracetamol should start to work within an hour and the effect usually lasts several hours. Don't take more than the recommended dose if it isn't relieving your symptoms. Adults can take ibuprofen at the same time if necessary, but this isn't usually recommended for children. For more details, see Can I take paracetamol and ibuprofen together? Contact your GP or call NHS 1. Be careful not to use other medications that contain paracetamol as an ingredient (such as some cold and flu remedies) while you're taking paracetamol. Taking paracetamol with other medicines, food and alcohol. Paracetamol can react unpredictably with certain other medications. This can affect how well either medicine works and might increase the risk of side effects. It may not be safe to take paracetamol at the same time as: other products containing paracetamol – including combination products where paracetamol is one of the ingredients carbamazepine – used to treat epilepsy and some types of pain colestyramine – used to reduce itchiness caused by primary biliary cirrhosis (a type of liver disease) imatinib and busulfan – used to treat certain types of cancerketoconazole – a type of antifungal medicinelixisenatide – used to treat type 2 diabetesmetoclopramide – used to relieve nausea and vomiting phenobarbital, phenytoin and primidone – used to control seizures warfarin – used to prevent blood clots. Check the leaflet that comes with your medicine to see if it can be taken with paracetamol. Ask a pharmacist or doctor if you're not sure. There are no known problems caused by taking paracetamol with any specific foods or by drinking moderate amounts of alcohol while taking paracetamol. It can be helpful to take any remaining medicine and the box or leaflet with you to A& E if you can. Some people feel sick, vomit or have abdominal (tummy) pain after taking too much paracetamol, but often there are no obvious symptoms at first. Go to A& E even if you're feeling well.
