Every fitness enthusiast is keen on protein shakes. The popularity of this beverage has only been growing, especially amongst fitness enthusiasts. For those who don't know, protein shakes are drinks made with protein powder. They come in a variety of flavors. You can make them by mixing the powder in water, milk, or another liquid. According to reports, one serving of most protein shakes has between 10 and 30 grams of protein. Healthy adults should get about 45 to 56 grams of protein a day, and most people get enough from food. However, if you exercise regularly, or otherwise live an active lifestyle, you may need more. And this is why some people resort to protein shakes.

Recently, nutritionist Suman Agrawal made an appearance at Ranveer Allahbadia's podcast where they spoke about weight loss and nutrition. On being asked if she is in favor of consuming protein shakes, the dietician said, "Yes. People over the age of 45 are recommended to consume protein shakes in a bid to enable calorie deficit. The aim is to ensure health maintenance and not muscle gain." She further added, "Protein shake ensures good immunity, high iron intake, skin and hair benefits."

Speaking about plant protein, she said, "It is high on carbs and difficult to digest. However, it completely depends on your body."

She further mentioned that one problem with protein intake is that it will definitely lead to constipation.

What is whey protein?

According to experts, despite being a popular fitness and dietary supplement, whey protein - the liquid that separates from milk during the cheese-making process, filtered, refined, and spray-dried into whey protein powder – is highly nutritional.

There are three main types of whey protein, and the difference between them is how they are processed:

Contains roughly 35–80 per cent protein apart from lactose, fat, and minerals from milk.

Contains 90-96 per cent protein and very little lactose or fat.

This form is pre-digested, which helps your body absorb it faster.

Apart from helping the athletes gain muscle, it also helps you recover from exercise, and gain strength as part of a resistance training routine. In addition, studies say whey protein aids weight loss for people who are obese and overweight.

Consuming more protein may help people feel fuller, which could help with shedding kilos.
