Everything you need to know about protein in the world of fitness and bodybuilding.

Proteins are a fundamental pillar in any athlete's diet. Their main role is structural: they repair, maintain, and build tissue—especially muscle. If you're training intensely, your protein needs increase significantly to help repair muscle fibers and support your immune system.

Who needs more protein?

While many assume only bodybuilders and strength athletes need high amounts of protein, several studies show that endurance athletes—such as runners, triathletes, and cyclists—may actually require more. Why? Although their muscle contractions aren’t as intense, the prolonged physical effort leads to significant muscle and connective tissue breakdown over time.

How much protein do I need?

Your ideal protein intake depends on your activity level and fitness goals:

• General recommendation (WHO): at least 0.8 g/kg of body weight per day.
  
  

• For active individuals: between 1.2 and 1.5 g/kg.
  
  

• For muscle gain: between 1.5 and 1.8 g/kg—or more if your diet is well balanced.
  
  

There’s no official “upper limit,” but excessive intake without proper hydration and a balanced diet can stress your liver and kidneys.

Best sources of protein.

• Animal proteins: lean meats, fish, eggs, poultry, low-fat dairy, and whey protein.
  
  

• Plant proteins: legumes, nuts, and whole grains.
  
  

What Is the biological value of protein?

Biological value (BV) measures protein quality based on:

1. Amino acid profile: quantity of essential amino acids.
   
   

2. Correct proportions of those amino acids.
   
   

3. Digestibility: how easily your body can absorb and use them.
   
   

Animal proteins tend to have a higher BV. For instance, egg protein has a BV of 100, while whey protein tops the chart at 110, thanks to its exceptional amino acid content and fast absorption.

Protein supplements: Yes or no?

You can absolutely meet your protein needs through whole foods, but protein powders offer some undeniable advantages:

• Fast digestion, ideal post-workout.
  
  

• Portable and convenient.
  
  

• Helpful if you have digestive issues or high protein demands.
  
  

Important: don’t fall into the trap of thinking "more protein = more muscle." Overloading your body—whether through supplements or food—can lead to dehydration, urea buildup, and organ stress. The problem isn’t the supplement itself, but uncontrolled intake.

Types of protein powders and when to use them.

1. Whey Protein.

The go-to post-workout protein. It digests quickly and boasts the highest biological value (BV 110). Ideal right after your training session, when your muscles are most receptive to nutrient uptake.

2. Sequential (blended) proteins.

These combine multiple protein sources to provide a sustained release of amino acids. Great for between meals, as a snack—like a shake with fruit or oats.

3. Nighttime proteins (casein).

During sleep, your body goes into full recovery mode. Casein digests slowly, making it perfect before bed. Avoid fast-digesting proteins like whey at night—opt for slow-release proteins to support overnight muscle repair.

Conclusion.

Protein is essential for anyone living an active lifestyle—whether you're building muscle, improving recovery, or just maintaining peak performance. Choose high-quality sources, spread your intake throughout the day, and don’t overdo it. Extra protein isn’t stored—it’s broken down and excreted.

Supplements are allies, not substitutes. Use them wisely, and make them part of a balanced fitness lifestyle.

Don’t eat less, train smarter: the strategy that will transform your body and metabolism for good.

 

Train with strength, eat better, and burn real fat.

For decades, we were led to believe that the only way to lose fat was endless hours of low-intensity cardio and constant hunger. But times change—and so does exercise science. Today, we know that a far more effective—and way more exciting—strategy to transform your body is about lifting more and eating better, not less.

❌ The mistake of endless cardio and restrictive diets.

Yes, cardio and watching your diet can help you lose weight—but in the long run, they might become your worst enemies. Why? Because cutting calories too much and overdoing cardio can slow down your metabolism, cause muscle loss, lead to postural imbalances, and push your body into "survival mode."

The result? You plateau, lose strength, feel drained, and fat clings to your waist like gold.

Sound familiar?

• You're training more than ever, but seeing no results.

• You're eating less every week, but the scale won’t budge.

• You feel weak, low on energy, and unmotivated.

If this is happening, it's time for a serious change:

👉 You need strength training.

🔥 The key isn’t eating less, It’s burning more.

The equation is simple: to lose fat, you need to burn more calories than you consume. But the smart way to do it isn’t starving yourself—it’s raising your resting energy expenditure.

This is done by increasing your basal metabolic rate (BMR)—the energy your body uses just to stay alive.
And here’s the kicker: muscle is your metabolic engine.
More muscle = higher metabolism = more fat burned 24/7.

🧠 Strength = smart fat burning.

When you only do cardio, you burn calories during the session... and that’s it. But when you train strength intensely:

• You boost post-exercise oxygen consumption (EPOC).

• Your metabolism stays elevated for hours.

• You stimulate fat-burning hormones like catecholamines.

• You build muscle—which burns calories even while you sleep.

The result? A 24/7 fat-burning machine. More energy, better mood, and no extreme diets.

🏋️‍♂️ It's not just about muscles, it´s about movement.

Forget about isolated exercises. Doing only biceps curls or hip abductions on machines won’t transform your body.

If you want definition and real fat burning:

✅ Prioritize compound and functional movements
✅ Use free weights: squats, deadlifts, presses, lunges
✅ Engage large muscle groups
✅ Combine upper and lower body in a single movement

Example? Lunges with overhead press, dips, kettlebell swings, pull-ups… these moves skyrocket your energy expenditure.

❤️‍🔥 Cardio? Yes, but use it wisely.

We’re not demonizing cardio—far from it. It has its place. But you don’t need to do it for hours on end.
3–4 sessions of 30–45 minutes per week is enough if combined with strength training.

Even better: Do your cardio after strength training to deplete glycogen stores and access fat reserves faster. Now that’s strategy.

📌 Action plan: effective workouts for fat loss.

🔰 FOR BEGINNERS

Functional Strength Circuit (2–3x/week)
Do 3 rounds of 20 reps per exercise:

• Dumbbell squats

• Lat pulldown

• Push-ups

• Dumbbell shoulder press

• Lunges

• Plank or weighted crunches

Perfect for activating major muscle groups, improving form, and starting to build lean mass.

If your goal is to lose fat effectively, sustainably, and without ruining your health:

✅ Train strength with intensity
✅ Eat enough, and eat quality food
✅ Use cardio strategically—not as punishment
✅ Sleep and recover properly

Forget the myth that getting lean means eating less and doing more cardio.
Build a strong, active body with an unstoppable metabolism.
Don’t think about diets—think about performance.
