The Benefits Of A High-Protein Diet For Muscle Building And Weight Loss

Table of Contents

Protein is key for our health, says the Dietary Guidelines for Americans. Men should get 56 grams a day, while women should get 46 grams.¹ But, new studies show eating more protein might help shed weight. It might also help keep or build muscle.¹

Eating proteins helps grow muscles. A good goal is 1.2 to 2 grams for every kilo you weigh. This helps with weight loss, saving muscle, and boosts your metabolism.¹ Research found that going up to 2 grams per kilo might make you stronger and keep your muscles from breaking down.¹ Also, people in a 6-month study lost more weight on a high-protein diet than those who followed the usual protein advice.¹

High protein foods can do more than help with weight and muscles. They might also keep your bones strong. This is crucial as we get older, especially for women after menopause.²

Key Takeaways : High-Protein Diet

Protein is an essential macronutrient for overall health and well-being.
Eating more protein than the recommended dietary allowance may aid in weight loss and muscle retention.
A high-protein diet can range from 1.2 to 2 grams per kilogram of body weight, helping with weight loss, muscle preservation, and increased metabolic rate.
Higher protein intake is associated with better bone health and a lower risk of osteoporosis and fractures.
Consulting a healthcare professional or registered dietitian is recommended when incorporating a high-protein diet.

What is a High-Protein Diet?

A high-protein diet means you eat more protein than the usual daily amount. This special amount helps avoid nutrient shortages and maintains muscle for most people.

Recommended Dietary Allowance (RDA) for Protein

The RDA for protein is 0.8 g per kilogram of body weight, or about 0.36 g for each pound you weigh. It sets a level to keep nutrients balanced and muscles strong for most folks.

Potential Benefits of Exceeding the RDA

Sometimes, going over the RDA in protein could lead to extra perks like losing weight or gaining muscle. Exceeding recommended amounts could contribute to these benefits.

High-protein diets usually pair with fewer carbs from sources like grains or certain fruits and veggies.³

How Protein Aids Weight Loss

High-protein foods may help you shed weight. They keep you full for longer and speed up your metabolism.⁴ Protein has a different impact on your body than fats and carbs. Research shows that it makes you fuller quicker.⁵

Increases Feelings of Fullness

Eating more protein makes you feel satisfied longer. It helps build lean muscle and boost your metabolism.⁵ This means you might feel less hungry during the day.⁵ A study found that older women ate fewer calories later if they had a high protein breakfast. They ate more after a low protein breakfast or skipping it.⁵

Boosts Metabolic Rate

Adding more protein to your diet can spike your metabolism. When you eat proteins, your body uses up to 30% of the calories for digestion. For carbs, it’s 10% and for fats, it’s only 3%.⁴ In a study, overeating on protein-rich food increased your daily calorie burn by 260.⁴ This is because your body works harder to digest proteins than other nutrients.⁶ Such a diet might make you burn an extra 200 calories a day. This can also increase your metabolism rate.⁶

Preserves Muscle Mass

Protein is key to keeping your muscles and metabolism strong as you lose weight.⁴ If you don’t get enough protein, you could lose a lot of muscle when shedding pounds.⁶ Increasing your protein intake can help. For example, going from 15% to 18% of daily calories from protein reduces the amount of lost muscle.⁶ A recent study found that older men managed to keep more muscle on a protein-rich, low-calorie diet. This was compared to a diet with less protein.⁶

Protein and Muscle Building

Protein is the key to building your muscles. To keep your muscles strong and growing, you need enough protein. This is even more effective when you also do strength training. Studies have proven that more protein helps you build more muscle and get stronger.⁷

Essential for Muscle Growth and Repair

In 2018, Morton and his team found that taking extra protein helps your muscles in a big way. Their study showed that adding protein to your diet makes your muscles bigger and stronger. According to Mamerow in 2014, spreading out your protein intake across the day is good for your muscles too. And in 2016, Macnaughton discovered that after a tough workout, your muscles use protein better if you have 40 grams of whey protein, instead of just 20.⁷

Helps Maintain Muscle Mass During Aging

As we get older, protein is still very important for our muscles. A 2017 study by Mitchell showed that giving more protein to elderly men for 10 weeks made their muscles and bodies work better. Hanach’s review in 2019 found that protein from dairy makes a big difference. It helps both young and older adults keep their muscles strong, improves their physical performance, even if they have a muscle disease called sarcopenia.⁷

Protein’s role in muscle health doesn’t fade with age. It becomes ever more important. By eating enough top-quality protein and working out, we can protect and increase our muscle mass and strength, no matter our age.

Other Benefits of a High-Protein Diet

A high-protein diet helps more than weight and muscle. It’s linked to better bone health and less risk of fractures when we’re older.² This benefit is key for women, especially those after menopause.

Supports Bone Health

Eating more protein is good for our bones. It helps keep our bone strength as we get older. Plus, it lowers our risk of osteoporosis and fractures.² This is very important for the elderly.

Reduces Cravings and Late-Night Snacking

In overweight men, 25% of calories coming from protein cut cravings by 60%. It also reduced late-night snacking by half.² This info is gold for those trying to lose weight but fighting off cravings.

May Lower Blood Pressure

More protein could decrease your blood pressure. On average, it lowered systolic by 1.76 mm Hg and diastolic by 1.15 mm Hg.² A high-protein diet might be good for the heart by reducing blood pressure.

High-Protein Diet

A high-protein diet is great for losing weight and building muscle. Experts say 1.2-2 grams of protein per kilogram of your body weight is ideal per day.³ So, for a 68 kg (150 lbs) person, that’s 82-136 grams daily.

Recommended Protein Intake for Weight Loss and Muscle Building

For protein, the Recommended Dietary Allowance (RDA) is 0.36 grams for each pound of weight (0.8 g per kilogram).⁸ But, eating more protein can help with losing weight and keeping your muscles strong.

It’s known that diets high in protein can aid weight loss. This is because it keeps you full.⁹ Protein also repairs your muscle tissue, important for keeping strong, especially with age.

Sample High-Protein Meal Plan

Here’s a sample meal plan packed with proteins:

Meal	Protein Source	Grams of Protein
Breakfast	2 large eggs, 1 cup of Greek yogurt	26.3 g
Snack	1 ounce of almonds, 1/4 cup of pumpkin seeds	14.8 g
Lunch	3 ounces of grilled salmon, 1 cup of cooked lentils	39.52 g
Snack	1 cup of cottage cheese, 1 slice of Ezekiel bread	34 g
Dinner	4 ounces of roasted turkey, 1 cup of quinoa	33.6 g
Total		148.12 g

This plan has around 148 grams of protein, good for a 68 kg (150 lbs) person. You can change the amounts and food types to fit your needs and likes.

Choosing Protein Sources

It’s essential to look at many kinds of protein sources when on a high-protein diet. Opt for both animal-based and plant-based options. Animal-based proteins offer meat, poultry, fish, eggs, and dairy products. Consider foods such as soy, beans, legumes, grains, and nuts for plant-based proteins.

Animal-Based Proteins

Animal-based protein sources are seen as complete since they have all essential amino acids. This is what the body must get. Think about meat, poultry, fish, eggs, and dairy for high-quality protein. For example, a big egg has 6.3 grams of protein⁸. A 3-ounce piece of turkey breast has 25.6 grams¹⁰. lean beef gives 24.6 grams of protein8. About 29.3 grams are in half a halibut fillet¹¹.

Choose lean and less processed animal proteins to cut down on saturated fat and sodium. Go for poultry without its skin, fish, and low-fat dairy as much as you can.

Plant-Based Proteins

Plant-based proteins include foods like beans, legumes, nuts, seeds, and soy products. While not all are complete proteins, many plant foods are high in protein. For example, one cup of cooked lentils has 9.02 grams of protein⁸. A quarter cup of pumpkin seeds gives you 8.8 grams⁸. Also, quinoa is a grain with 8 grams of protein in one cup⁸.

By mixing various plant-based proteins, you get all the essential amino acids. For instance, you can eat beans with rice or nuts with whole grains for a full amino acid set.

For a high-protein diet, include a mix of animal-based and plant-based protein options. This ensures you get all essential nutrients and amino acids.

Risks and Considerations

High-protein diets are usually safe for most people. But, there are some risks to keep in mind. Make sure you’re informed.

Impact on Kidney Function

Diets high in protein might not be great for your kidneys, especially if you have kidney issues. When your body breaks down protein, it creates more waste, which can stress the kidneys.¹²

Research shows this issue is more critical for women with kidney health problems. It’s also linked to an increased risk of forming calcium stones in your urine. Stones were discussed in studies by Fellstrom B et al. in 1983 and Robertson WG et al. in 1979.¹²

Potential for Nutrient Imbalances

Eating too much protein and not enough carbs can cause you to miss out on essential nutrients and fiber. Without these, you might get bad breath, headaches, or have trouble going to the bathroom.⁹

If you stick to a high-protein, low-carb diet for too long, it could affect your health. Studies have found issues like too much albumin in the blood or high transaminases from this diet. A study by Mutlu E et al. in 2006 looked into it.¹²

To avoid these downsides, choose your protein wisely and don’t forget about fiber. It’s key to eat a balanced diet.⁹

Before making big changes to your diet, especially if you have existing conditions like kidney disease or diabetes, talk to a doctor.⁹ They can help you steer clear of any pitfalls and tailor your diet to your specific needs.

Incorporating a High-Protein Diet

To dive into a high-protein diet, remember a few essentials. Keep an eye on how much protein you eat. Make sure you don’t forget about carbs and fats, too. It’s wise to check with a pro to guide you.

Tracking Protein Intake

For adult women, it’s good to aim for at least 46g of protein every day. Men should try for 56g.¹³ Having more protein than the basic needs might lower your chances of health issues. This includes type 2 diabetes and heart disease.¹³ Keep a food log to see if you’re hitting your protein targets. Be sure to eat a mix of protein-rich foods like meat, eggs, and nuts.

Balancing Macronutrients

It’s not just about protein in a high-protein diet. It’s also important to get your carbs and fats in the right amount. Adding veggies and protein before carbs can help keep your blood sugar steady.¹³ Meal planning to balance what you eat can help you reach your health goals better.

Consulting a Healthcare Professional

Thinking of going high-protein? Talking to a doctor or dietitian first is smart. They can figure out how much protein is right for you. They’ll also give tips on eating a balanced, protein-rich diet. This is tailored to your needs and keeps any health risks in check.
