Fitness has become a part of every individual’s life these days. Being a gym enthusiast, a sports person, or just wanting to remain healthy, everyone wants the same thing: to become muscular and fit with zero extra pounds. In such a case, protein powder can be a huge savior.
But the issue is that there are numerous protein powders available in the market, and it’s challenging to understand which one is perfect for you and which is for the sake of it. Several powders have unnecessary sugar, fillers, and calories, which can nullify your efforts.
So, you need to select protein powders that are clean, low-calorie, and give the proper amount of nutrition to your muscles. In this article, we’re going to inform you about 7 of the top protein powders that are great for muscle growth, are very low in calories, and will get you a lean and toned physique.
Why Protein Powder Matters for Muscle Growth
Protein is the primary building block of our muscles. When you lift weights or do high-intensity exercise, your muscles create small microtears (similar to small wounds). The body requires protein, or amino acids, to mend these wounds and make them stronger.
So now you may be thinking, “So can I obtain protein just through food?” The answer is yes, but it’s not always easy.
- The amount required daily is high: A typical fitness enthusiast requires a minimum of 1.5–2 grams of protein per kilogram of weight. If you weigh 70 kg, you require 105–140 grams of protein per day.
- Diet difficulty: It’s somewhat challenging to fulfill this much protein demand with only lentils, vegetables, eggs, and milk.
- Calorie control: Occasionally, consuming large amounts of protein contributes to the intake of extra fat and calories along with protein, causing you to gain fat.
This is where protein powder saves the day. It is a convenient, quick, and highly concentrated source. Simply combine one scoop with milk or water and you have fulfilled much of your daily protein requirement.
What to Look for in a Lean Protein Powder
There are numerous protein powders on the market, but not all of them are suitable for you. When selecting a protein powder for lean bodybuilding, consider the following points:
- Protein content: The serving should have at least 20–25 grams of protein.
- Low calorie: A single scoop should have no more than 120 calories.
- Low sugar and low carb: Less than 2 grams of sugar per serving.
- Clean ingredients: No fillers, additives, or artificial flavors.
- Digestibility: Whey isolate, hydrolyzed protein, or plant protein is best since they are easier to digest.
