Top Protein Myths You Should Stop Believing

Protein, an essential macronutrient plays an important role in muscle gain, body building and supporting immunity. Amongst the various protein facts, several protein myths also exist. From having more protein for muscle gain to choosing a protein supplement over meals, these are only a few of the protein misconceptions.

Understanding the benefits of protein is as important as debunking the protein misconceptions. So let’s breakdown the seven protein myths that may be directing your focus away from what truly matters, alongside other aspects, and help you make better dietary choices.

Why Protein is Important for Health and Fitness?

Protein is necessary for the growth and maintenance of tissues, production of enzymes and hormones, immune system functioning and weight management.[i] As adequate protein intake contributes to satiety, it is important to include protein for weight loss as a part of a balanced diet. Factors such as the age, body weight, activity levels, underlying medical conditions, if any and health goals can influence the daily protein intake of a person.

Myth #1: Protein Is Only for Bodybuilders

Body builders are not the only ones gaining the benefits of protein, although they need protein for muscle gain. Emphasizing protein for weight loss is important as protein has a thermic effect, which means your body utilizes more amount of energy to digest and absorb protein compared to carbohydrates and fat.[ii] For older adults, protein for muscle gain is also vital to help prevent sarcopenia (age-related muscle loss). To maintain your daily protein intake, include adequate amount of protein rich foods in the diet.

Myth #2: More Protein Always Means More Muscle

The idea that eating high amounts of protein-rich foods and having different protein shakes or supplements for building muscles is amongst the common high protein diet myths. However, it is the combined approach of resistance training alongside adequate energy and protein intake which contributes to muscle building.2

Myth #3: Whey Protein Is Harmful

Whey protein is a high-quality milk-derived protein that contains all the essential amino acids. When included as part of a balanced diet to meet your protein needs, it does not harm your body. Lack of general awareness and knowledge may make people believe into one of these whey protein myths, that it is harmful. However, if you have lactose intolerance, or existing medical conditions, consult your healthcare provider before including it in your diet.[iii]

Myth #4: Vegetarians Can't Get Enough Protein

Plant-based diets are deficient in protein, which can affect the daily intake of vegetarians is one of the protein myths. The fact is, a well-planned vegetarian diet can provide adequate protein. Using the right combinations of plant based protein sources (cereals with pulse), including variety, and consuming sufficient quantity of protein at every meal matters. For e.g. vegetable dal khichdi/paneer pulao +raita or any pulse based idli/dosa or soya granules paratha +curds are good protein-rich vegetarian meal options.

Myth #5: Protein Causes Weight Gain

Weight gain depends on overall energy intake, sedentary lifestyle, sleep, genetics and medical conditions.[iv] Protein contributes to weight gain if your total calorie intake exceeds your daily energy requirements. Additionally, adequate intake of protein for weight loss is widely advocated as including protein-rich foods in the diet helps control hunger and reduce cravings.

Myth #6: You Only Need Protein after Workout

This can actually mislead people making them think they need to consume more protein only after workout. As a result, they may believe in one of these high protein diet myths and may overlook their overall protein intake of the day. You do require a moderate amount of protein to support muscle repair and recovery after training. But your body also requires a balanced intake of protein throughout the day, irrespective of whether you work out.

Myth #7: Protein Supplements Can Replace Meals

Of the various protein misconceptions, this is another widespread common myth that you can just swap your meals with a protein supplement. To meet your daily nutritional requirements, you need to include a balanced diet providing a variety of nutrients. Protein supplements can only be a part of the daily diet as advised by a healthcare professional, to meet the nutritional gaps, if any, and cannot replace your meals.

How Much Protein Do You Actually Need?

The average daily requirement of protein for adult men and women >18 years of age according to the Recommended Dietary Allowances (RDA) of Nutrients for Indians is mentioned below:[v]

Protein is also required for growing children, older adults, and the requirements differ during pregnancy, lactation, intensive training and also during recovery from illness. If you are unable to meet your daily protein intake, your doctor or dietitian may suggest a suitable protein supplement, alongside a balanced diet.

Best Sources of Protein

The best sources of protein include both non-vegetarian and vegetarian protein sources. The non-vegetarian protein sources include milk and milk products (curd, paneer and yogurt), eggs, chicken and fish. For vegetarian protein sources, include pulses, lentils, soybean and products, nuts, seeds, and quinoa in the diet.

Frequently Asked Questions

1.      Will consuming a high protein diet damage my kidneys?

No. You must have come across this as one of the high protein diet myths often. People with healthy kidneys and adequate hydration can handle the increased load of nitrogenous waste from protein metabolism without any damage. The risk arises only in people with pre-existing kidney disease as their kidneys struggle with the process of additional filtration.[vi]

2.      Can vegetarians build muscle without supplements?

 Paying heed to the right food combinations and consuming adequate protein along with consistent strength training can support muscle growth in vegetarians. They can mix up various vegetarian protein sources in their diet to help increase the protein intake. For example, chapati + pulses/lentils/soya chunks/paneer +vegetables +curd.

Thus, with a better clarity on various protein myths, and to optimize your nutrition, focus on meeting your nutritional needs through a balanced approach. To gain the benefits of protein, focus on adequate intake, quality and variety, as this is far more important than believing and following every protein trend.
