Protein help in building muscles, but can you eat too much Protein?

Protein is essential in your diet, but piling more onto your plate isn’t always better. too much protein can strain kidneys, cause side effects and go unused beyond what your body can absorb. Walk through the grocery store these days, and it seems like protein is everywhere. Protein cereal. Protein pancakes. Protein bars. Even protein chips. It all fits into the “protein maxxing” eating trend. But while protein is an important part of any diet, eating more isn’t always necessary or healthy. You can get too much of a good thing. So, how do you know what’s right for you when it comes to protein? “It starts with understanding your body’s true protein needs, some people do need more — but that’s not the case for everyone. High protein content has become a selling point on foods ranging from breakfast cereals to yoghurts. For anyone hoping to build muscle or stay strong as they age, choosing the product with the most protein can seem sensible. But whether an extra serving will help depends on what they already eat and how they use their muscles.

A middle-age man exercises with hand weights in a gym. Body builders and people who exercise vigorously rarely need more than 0.75 grams of protein/pound of body weight daily. For a 180-pound man, that would be a total of 135 grams of protein/day. A person who rarely exercises needs half that amount - about 0.37 grams/pound of body weight/day. Regarding how much protein can be digested and absorbed in the intestine at one time, there is no specific maximum amount. However, the body will only use what it needs. Someone who regularly lifts weights may benefit from additional protein to support muscle growth. An older person with a small appetite may need help getting enough to maintain strength. Someone already eating enough protein may gain little from adding more. Understanding those differences can make it easier to decide whether to change your diet, buy a supplement or concentrate on exercise. To build muscle, the maximum amount of protein to take at one time is 25 to 30 grams. Additional protein can be absorbed and used for other bodily functions. When we eat high amounts of protein, the body (especially the kidneys) needs to work hard to get rid of all the nitrogen in proteins. Too much dietary protein can have adverse consequences. These include:-

dehydration

gout

kidney stones.

A question body builders and athletes often ask is whether the type of protein matters. There is no definite proof that one type of protein builds more muscle than any other type. Fish, vegetable, bean, and nut proteins are healthier. They don't contain the saturated fats that accompany animal proteins. If you are looking for a protein supplement, one that contains a mixture of casein and whey is a reasonable choice. They are broken down into peptides (small pieces of protein) and amino acids, which are more easily absorbed.

Muscle tissue is continually being broken down and rebuilt. Dietary protein supplies amino acids, the small molecules the body uses to make its own proteins, including those in muscle. Resistance exercise makes muscles work against a load. The load might come from weights or from your own body during an exercise such as press-ups. It stimulates the processes involved in building and repairing muscle, allowing muscles to adapt to repeated demands. Protein supports this adaptation, but increasing intake does not reproduce the effects of exercise. The Dietary Guidelines recommends that adults aim to eat 1.2 to 1.6 grams of protein/kilogram of body weight/day. For a typical 150-pound (68-kilogram) person, that means eating roughly 80 to 110 grams of protein/day. This puts you in the ballpark of what you should aim to consume. From there, factors like your activity level and age help determine if you need more protein. Workout warriors who exercise regularly and intensely, for example, likely need more daily protein. But that still doesn’t mean you should try to pack in as much protein as possible when you sit down for a meal. The reason? Research suggests that 25 to 35 grams of protein/meal is the maximum amount our bodies can use at one time for muscle building. Consuming protein beyond that in one sitting won’t harm you, but it’s unlikely to increase muscle protein synthesis. Instead, spreading protein intake evenly throughout your day is most beneficial for maximizing muscle growth and repair. A study found that protein supplements produced additional improvements in muscle size and strength during resistance training. Participants were training for at least six weeks. The findings therefore concern protein’s contribution to a training program, rather than the effects of adding a shake to an otherwise unchanged routine. For someone already eating enough protein, establishing a manageable strength-training routine may be more useful than searching for another high-protein snack.

Muscle health has consequences well beyond appearance. Losing strength can make getting out of a chair or carrying shopping harder, threatening independence. Older muscles can become less responsive to the muscle-building effects of a meal, a phenomenon called “anabolic resistance”. This means the same amount of protein may produce a weaker muscle-building response than it does in younger people. Needs can differ during illness, and people with significant kidney disease may require individual advice. However, preserving muscle involves more than increasing protein. A year-long trial found that protein supplementation alone did not improve muscle size or strength compared with carbohydrate supplementation. Heavy resistance training combined with protein produced benefits that supplementation alone did not. The practical implication is that advice about protein should also consider opportunities to exercise. Increasing intake without addressing inactivity may leave an important part of muscle maintenance neglected. People undertaking resistance training may benefit from more. In a trial, additional protein did not appear to produce further gains in fat-free mass, which includes muscle, once total daily intake reached around 1.6g/kilogram of body weight. For a 70kg adult, that would be about 112g from all food and supplements combined. The figure is an estimate across studies, rather than a precise threshold for every person. It does not mean everyone needs to aim for it. Existing protein intake and training demands affect whether additional protein is likely to help.

Before buying supplements, consider the protein already supplied by ordinary meals. A supplement may be convenient when food alone does not meet someone’s protein needs. But if their diet already provides enough protein for their activity level, a supplement may offer little extra benefit while increasing costs. Cottage cheese is one convenient source of protein, but plenty of alternatives are available. Other dairy foods and eggs provide protein, as do beans and soy foods. Preferences and affordability will influence which options someone can eat regularly. Regularly eating too much protein can come with health risks, especially if most of it comes from animal-based foods or nutritional supplements. These include:-

Diets that are very high in animal protein may make kidney stones more likely for some people.

A high-protein diet can be a concern if a lot of that protein is coming from red meat or processed meats with high amounts of saturated fat, which brings increased risk of heart disease.

Focusing on protein shakes, meat or other high-protein foods can push plant-based foods off your plate. In that situation, you may end up getting less fiber, vitamins and other nutrients your body needs.

Your kidneys help clear out the waste that’s made when your body breaks down protein. If you consistently take in more protein than your body needs, it can stress or even damage your kidneys.

If you’re overdoing it on protein, your body may let you know. Signs that a high-protein diet is getting too high can include:-

Protein contains calories, about 4 calories/gram. If extra protein pushes your total calorie intake above your needs, it can lead to weight gain or make weight loss harder.

High-protein diets can contribute to constipation, especially if protein-rich foods are replacing fiber-rich foods like fruits, vegetables, legumes and whole grains.

Very high-protein diets, especially those that are also very low in carbohydrates, can sometimes cause unpleasant breath. This side effect is often called “keto breath.” (It can be a byproduct of following the keto diet.)

Processing large amounts of protein can lead to dehydration. It’s because your body pees out more water to help get rid of the waste from breaking down all that protein.

Protein maxxing doesn’t need to become a numbers game where the highest total wins. Instead, experts recommends figuring out what you need and building a balanced diet around that target. These strategies can help:-

Don’t let a focus on protein squeeze everything else off your plate. A varied diet provides fiber, vitamins, minerals, antioxidants and other nutrients which protein alone can’t deliver.

Track a typical day before deciding you need more protein. If you’re meeting your needs, maybe rethink adding more. If you’re short on protein, try eating more whole-food sources of lean protein before just using protein shakes and similar protein supplements.

Spread protein throughout the day. Rather than eating most of your protein at dinner, as many people do, aim to include some at each meal. Balance your day by adding protein to breakfast and lunch.

Beans, nuts, seeds and other plant-based foods can increase protein intake while supplying fiber and other nutrients not found in animal products. Plus, eating more plant-based protein can reduce your risk of chronic diseases like diabetes, heart disease and obesity.

Protein powder can be a convenient option if you need to boost protein intake to meet your needs, but don’t just add it to push numbers higher.

As a starting point, multiplying your weight in pounds by 0.5 to 0.75 to estimate a general range of grams of protein/day. Adjust from there based on factors like age and exercise routines.

You probably don’t need to add protein to everything you eat simply because it’s available. Focus more on getting your protein through whole foods.

Remember that while protein is important to your diet, there’s no prize for pushing your intake numbers higher through protein maxxing. Be satisfied with hitting your specific protein target.
