Constipation can be short-term or chronic, and it can be caused by a wide range of factors, including a sedentary lifestyle and digestive problems. Constipation relief and poop elimination are two major benefits of fiber. Soluble fiber and insoluble fiber are two different types of fiber in food. Both foods rich in one or both can help you alleviate constipation on occasion and on a regular basis. Drink hot beverages such as coffee or tea to help you boost your metabolism. Natural laxatives may cause diarrhea, cramping, and bloating, so use caution when taking them. Make sure you drink plenty of water to boost your fiber intake and keep hydrated.

Chronic constipation, overindulgence in fried foods, processed meats, and other high-fat foods, and other health conditions may all be to blame. Constipation is a natural part of the keto diet, which is high in fat. Intermittent fasting, in addition to keeping weight and preventing disease, can even reverse some types of disease.

Are There Any Cons To Drinking Whey Protein Shakes

Unfortunately, despite all the positives associated with drinking whey protein shakes, there are also some negatives. Despite being relatively minor, there are some side effects that can cause a lot of discomfort.

These problems are digestive, and they can wreak havoc on your stomach and insides.

However, it is important to determine the cause of digestive issues. The cause may be how you are preparing your shake or what types of ingredients you are using rather than the type or brand of whey protein shake.

When Should One Take Whey Protein


This is a question that is often asked by many people who are interested in consuming whey protein but do not know how to go about it properly. It is not tough to learn when to take this protein to reap its benefits.

Firstly, if you want to take whey protein on its own, you should do it within half an hour to an hour after a workout that is based on strength training. This is because this protein gets digested very quickly. During other times, you should eat it with other foods so that digestion can be slowed down. For instance, for extra protein in your breakfast without foods like eggs, you can add whey protein to your oats in powder form.

Secondly, if you want to have a healthy snack while you are in the office, you can have a whey protein-shake combined with a bit of fish oil or nuts. This again will help in slowing down the digestion process of the protein. The fat combination is what helps slow down digestion and this in turn benefits you greatly by allowing the levels of insulin in your body to stay even. It also aids in the stimulation of CCK, which is a hormone that lets your body know when it is full.

Protein that is digested after a workout gives your body the amino acids that it needs for the repairing and building of new muscles. According to experts, consuming whey protein as soon as you complete a workout could be especially beneficial as it has a rich content of Leucine, an amino acid that is easily absorbed by the body.

Adding protein powder to a glass of milk or a smoothie may seem like a simple way to boost your health. After, all, protein is essential for building and maintaining muscle, bone strength, and numerous body functions. And many older adults dont consume enough protein because of a reduced appetite.

But be careful: a scoop of chocolate or vanilla protein powder can harbor health risks. I dont recommend using protein powders except in a few instances, and only with supervision, says registered dietitian Kathy McManus, director of the Department of Nutrition at Harvard-affiliated Brigham and Womens Hospital.

If I Have Constipation After Drinking Whey Protein Does The Protein Go To Waste

Getting Constipated on a Bodybuilding Diet

You may become constipated if you dont eat enough high-fiber foods like vegetables, fruits, and whole grains. Also, eating a lot of high-fat meats, dairy products and eggs, or rich desserts and sugary sweets may cause constipation. People who live alone may lose interest in cooking and eating.

Whey Protein: Kidney And Liver Function

Even during short-term use, whey protein consumption was found to negatively affect kidney function. In a 2011 study, those who consumed whey protein during the experiment experienced increased plasma urea, urinary volume, and urinary calcium excretion while the pH of urinary citrate decreased. Essentially, this indicates an increased taxing of the kidneys, which marks the first step in kidney disease.In regards to liver function, those who live generally sedentary lives are most affected. Researchers found that when not exercising, the proteins from the whey supplement ended up going to the liver for processinginstead of being used for muscle synthesis. Over time, sedentary participants showed signs of early liver injury. While whey protein is heavily used by athletes, many non-athletes consume it as well. Whey protein can be found in meal replacement shakes and other diet-related food products that promise weight loss or increased muscle mass through food alone. This becomes an issue because consumers are led to believe that whey is akin to a superfood, when in reality it could damage their liver over time.

Can It Cause Constipation And Nutritional Deficiencies

Constipation is not a normal side effect of whey protein.

For a few people, a lactose intolerance may cause constipation by slowing the movement of the gut .

However, constipation is more likely caused when people eat fewer fruits and vegetables in favor of whey protein, especially when theyre on a low-carb diet.

Fruits and vegetables are a great source of fiber, which helps form stool and promotes regular bowel movements .

If you suspect that whey protein makes you constipated, check whether you are eating enough fruits and vegetables. You can also try taking a soluble fiber supplement.

Another reason why replacing whole foods with whey protein is a bad idea is because it may increase your risk of nutrient deficiencies.

Whole foods, especially fruits and vegetables, are nutrient-rich and contain a variety of minerals necessary for optimal health.

Therefore, its important to keep eating a balanced diet while youre taking whey protein.

Can It Damage Your Liver

No evidence shows that too much protein can damage the liver in healthy people .

In fact, the liver needs protein to repair itself and convert fats to lipoproteins, which are molecules that help remove fats from the liver .

In a study of 11 obese women, taking 60 grams of a whey protein supplement helped reduce liver fat by approximately 21% over four weeks.

Moreover, it helped reduce blood triglycerides by approximately 15% and cholesterol by about 7% .

One case report implied that a 27-year old male could have suffered liver damage after taking whey protein supplements .

However, he was also taking a variety of other supplements. Doctors were also unsure if he was taking anabolic steroids, which can damage the liver .

Considering that thousands of people take whey protein without liver problems, this single case provides insufficient evidence that whey protein can damage the liver.

Although, a high protein intake may harm people who have cirrhosis, a chronic liver disease (

36 ).

Summary: There is no evidence that whey protein can cause osteoporosis. In fact, whey protein may help prevent the disease.

Ingredients That Should Never Be In Your Protein Powder

Heres what you DONT want in a protein powder:

1. Casein + WPC

These are also known as whey protein concentrate and sodium caseinate. WPCs and casein protein sources are high in lactose and more difficult to absorb, which can often cause bloating, flatulence, and gastrointestinal distress. It is quite ironic that these powders actually started off as a weight gainer in medical institutions!

2. Gluten

Food sensitivities to gluten can elevate inflammation in some people and cause a range of health problems including hormonal imbalances, skin conditions, fatigue, mood swings, and headaches.

3. Dextrins/Maltodextrin

These ingredients can raise glycemic load, which may contribute to fat storage. Most are processed with GMO corn and they can also cause gastrointestinal distress in some people. They are mostly added to protein powders as fillers to bulk it out or make the protein mix easier.

4. Artificial sweeteners

Common artificial sweeteners used are Sucralose , Aspartame , and Saccharin . Some people may experience negative reactions to artificial sweeteners and side effects may include headaches, migraines, gastric distress, depression and weight gain.

5. Skim milk powders/milk solids

Skim milk powders and milk solids are often used as a cheap bulking agent in lower quality powders.

They are high in lactose sugars, which can cause bloating, gastrointestinal distress, constipation, and loose stools.

6. Soy protein

7. Vegetable oils and fats

8. Thickeners and gums
