There’s no denying how effective protein shakes are in helping people to bulk up.

However, what happens when you take them without working out?

As you may already have guessed, all those nutrients have to go somewhere. But where exactly do they go?

To answer this question, we’ve spent hours researching how these shakes affect the body to determine whether or not you should be worried.

Can I Drink Protein Shakes Without Working Out?

You can drink protein shakes on your rest days or without working out as long as you know your bodily needs. But if you don't exercise and protein shakes add a lot of calories to your diet, you might gain weight.

An athlete or a bodybuilder often uses shakes to increase the daily intake of proteins. This extra protein boost allows them to build muscle and get the most out of their workout.

Additionally, they may also be taken as a meal replacement to assist with weight management.

As shakes are in liquid form, this allows getting high on protein without the need to overload the digestion.

The biggest concern with drinking protein shakes when not working out includes side effects such as diarrhea, constipation, dehydration, and weight gain.

In most cases, if you decide to drink protein shakes and not exercise, any extra proteins will simply be flushed out by your digestive system.

Is It Safe To Take Whey Protein Without Working Out?

It is safe to take whey protein without working out as long as it is done in moderation.

Whey is a protein that is derived from milk during cheese production.

This protein is usually processed into powder form and sold as products like protein supplements.

Whey is a complete protein that contains essential amino acids needed for muscle growth.

This makes it highly efficient at muscle protein synthesis, a process where your bodily systems produce proteins to repair damaged muscles after workouts.

According to scientific tests, “a group of researchers found that whey protein can facilitate muscle recovery and may hold particular relevance for athletes engaging in high-intensity, explosive sports. [1]”

What Goes Into a Protein Shake?

A protein shake consists of a scoop of protein powder mixed with water or milk. Protein shakes are often created using a combination of protein powder, frozen fruit, ice, seeds and nuts, and liquid.

The amount of powder added depends on your weight. This is calculated at a ratio of 0.36 grams of protein per pound of body weight.

Other common foods that are added to a shake include:

  • Base liquid: This often consists of milk, water, or both. Milk is a good choice for extra proteins and to add richness to the shake.
  • Protein powder: Popular choices include whey, casein, and plant proteins.
  • Fruits: Bananas, strawberries, pineapple, mango, and blueberries are rich in vitamins and provide sweetness.
  • Veggies: Greens like kale, spinach, chard, and lettuce add a ton of extra nutrients and minerals.
  • Even more protein: In addition to powder, whole foods such as chicken breast, eggs, chocolate, seeds, yogurt, and fish can be added to the blended shake. Talk about protein overload!

How Do Protein Shakes Affect Your Body?

Protein shakes affect your body by helping you grow muscle mass while improving your performance and recovery. They also aid in preventing muscle loss and may even help you gain muscle mass when trying to lose weight.

Increased Regeneration and Maintenance of Muscles

Proteins are responsible for the building and maintaining of muscle tissue.

Taking a shake as part of your diet helps repair damaged muscle fibers strained from working out. Over time, this increases muscle mass, strength, and size.

Consuming proteins along with intensive training in a workout will damage muscles further, leading to optimal results.

Healthy Fat Loss

Compared to carbs or fats, proteins are more satiating and help you feel content.

Taking a shake makes you feel full due to the volume of liquid in your stomach.

This helps curb food cravings, reducing the intake of food you eat on your diet and minimizing your calories.

Additionally, a shake can be used to replace a meal while still providing you with essential nutrients.

Replacing meals with a shake can help you achieve your weight loss goals by eliminating excess calories and increasing metabolism.

This is why people often use a shake as a meal replacement when they’re on a diet and want to lose a few pounds.

They may even consume them in place of breakfast, lunch, dinner, or even alongside them, depending on their hunger level.

It is important to note that your body's protein demand per day will be low if you are not working out.

This means the more shakes you consume as part of your diet, the higher your calorie intake.

If you consume too many shakes without exercise alongside your usual diet, it will lead to eventual fat gain due to increased calorie intake.

Lastly, excess protein needs to be excreted from the system as waste.

Eating too much protein per day results in a lack of water, which overworks the kidneys. As a result, people at risk of kidney disease should be especially cautious about their protein intake.
