Protein is one of the most important macronutrients for overall health, muscle growth, and recovery. Whether you’re an athlete, trying to lose weight, or simply looking to maintain a balanced diet, ensuring you get enough protein is crucial. But how much do you actually need, and where should you get it from? Let’s dive into the science behind protein and the best ways to incorporate it into your diet.
The Role of Protein in the Body
Protein plays a fundamental role in nearly every function of the body. Here’s what makes it so essential:
- Muscle Growth and Repair – Protein provides the amino acids needed for building and maintaining muscle tissue. This is especially important after exercise when muscle fibers need repair (1).
- Metabolism and Weight Management – Protein has a higher thermic effect than carbohydrates or fats, meaning your body burns more calories digesting it. Additionally, it promotes satiety, helping control appetite and reduce cravings (2).
- Enzyme and Hormone Production – Many enzymes and hormones in the body are made from protein, including insulin, which regulates blood sugar, and neurotransmitters that affect mood and cognitive function (3).
- Immune System Support – Antibodies that help fight infections and diseases are also proteins. A diet rich in high-quality protein supports a strong immune system (4).
How Much Protein Do You Need?
The ideal protein intake varies depending on your age, activity level, and goals. Here’s a general guideline:
- Sedentary individuals: ~0.8g per kg of body weight
- Active individuals & athletes: ~1.2-2.0g per kg of body weight
- Muscle-building or weight loss goals: ~1.6-2.4g per kg of body weight
For example, a 70 kg (154 lbs) active person should aim for 84-140g of protein per day.
Whole Food Protein Sources
While protein supplements are an easy way to boost your intake, whole food sources should always be a priority. Here are some of the best options:
Animal-Based Protein Sources:
- Chicken breast (31g per 100g)
- Salmon (25g per 100g)
- Eggs (6g per egg)
- Greek yogurt (10g per 100g)
- Lean beef (26g per 100g)
Plant-Based Protein Sources:
- Lentils (9g per 100g cooked)
- Chickpeas (8g per 100g cooked)
- Tofu (10g per 100g)
- Quinoa (4g per 100g cooked)
- Almonds (6g per 28g)
When and How to Supplement with Protein
For those who struggle to meet their daily protein needs through whole foods alone, protein supplements can be a convenient and effective solution. A general rule of thumb is to get 80% of your protein needs from whole foods and 20% from supplements.
A high-quality plant-based protein powder like Protein+ provides a balanced amino acid profile and is easier to digest than typical protein powders. Whether in a shake, smoothie, or added to oatmeal, it’s a simple way to meet your protein goals.
Final Thoughts
Protein is essential for overall health, performance, and longevity. Ensuring you get enough protein—whether through whole foods or supplements—will support muscle growth, weight management, and overall well-being.
If you’re looking for a simple way to boost your intake, a high-quality protein supplement like Protein+ can help bridge the gap while keeping your nutrition clean and effective.
