Protein has become one of the most popular and discussed nutrients in the fitness and health world, but it can be surprisingly confusing to determine your daily protein intake. There's a lot of conflicting advice out there, along with marketing hype from supplement manufacturers, and it's easy to fall into the trap of eating too little, or too much in the form of supplements. This blog will review how to calculate the protein for daily consumption based on the goal, then take a detailed look at the daily protein needs for women, and then a detailed look at the daily protein intake for men, and finally we will look at the official daily recommended intake of protein and try to distinguish the real from the hype.
Why Daily Protein Intake Matters
Protein is much more than just for the muscles. It helps in controlling the immune system, hormone secretion, enzyme activity, and repair of tissues in the body. Regardless of whether or not you're training to build muscle, protein is essential to maintaining energy, satisfaction and exercise recovery.
The body cannot store excess protein for later use the same way as it can with carbohydrates and fats; this is why it is important to have it every day instead of only during high-protein feasts. That's why knowing your own daily protein needs rather than a blanket recommendation is better.
Daily Recommended Allowance of Protein
Most health authorities prescribe about 0.8 g of protein per kg of body weight as the daily recommended intake for a sedentary adult person. The daily recommended intake for protein is based on preventing deficiency, and is not meant to promote muscle growth, optimize athletic performance, or achieve body composition goals.
This is approximately 56 grams of protein a day for a 70 kg person, which might sound low compared to the 80–100 grams recommended by fitness influencers. This is a minimum daily requirement for protein, and many nutritionists have increased the amounts for people who are physically active, older adults, or those who want to lose weight and maintain muscle mass.
How to Calculate Your Protein for Daily Intake
Instead of using generic numbers, determining how much protein you need for your goals will give you a more accurate amount to aim for.
- Lightly active adults: 1.2–1.5 grams per kilogram of body weight
- Athletes participating in recreation: 1.2–1.6 grams/Kg of body weight
- Muscle building or strength training: 1.6-2.2g/kg of Body Weight
- Weight loss while preserving muscle mass: 1.6–2.4 grams per kg of body weight; additional protein will help to keep you feeling full and lower muscle loss when on a calorie deficit.
- Older adults (60+): 1.0-1.2g/kg of body weight, because older adults are not as efficient at using protein for muscle maintenance.
These ranges allow you to determine your own protein target for the day, rather than choosing one generic protein number from the Internet or elsewhere.
Daily Protein Needs for Women
It is important to discuss daily protein requirements for women because there is much misinformation about the daily protein requirements of women.
In fact, the amount of protein that women need each day should be determined based on their weight and activity, not gender. Women undergoing a regular strength training program or who are pregnant or nursing may require greater levels of protein than the minimum recommended daily intake.Strength training women, pregnant women, nursing women and women with weight loss goals may require higher levels of protein than the minimum daily recommended intake. When looking at how much protein pregnant women need, they normally need an additional 15-25g a day on top of their baseline to support the developing foetus, so this is one of the key things to consider when planning protein intake for women in different life stages.
Daily Protein Intake for Men
Likewise, the amount of protein that a man should be eating each day should be adjusted to a person's own preferences, needs and objectives and not assumed that men need a lot more protein per kg of body weight than women.
For men who are involved in regular strength training or endurance sports, the 1.6–2.2 grams per kilogram mentioned above are fairly typical, and for men who drink protein daily to increase muscle mass, the upper end of that range is probably best, especially if they are also doing resistance training. However, just increasing protein intake without sufficient strength training won't lead to muscle development — protein will aid the process but it is not a substitute for regular strength training.
Best Sources to Meet Your Daily Protein Intake
It's easier to get your daily protein recommendation if you know the foods that offer the most protein per serving.
- Eggs: approximately 6 grams per egg
- Kidney Beans: 21 grams per 100 grams
- Lentils and dal: approximately 9 grams per 100 grams of cooked lentils or dal
- Beef, pork and lamb: around 30 g per 100 g
- Tuna: 15 grams per 100 grams
- Tofu and soy products – approximately 8-15g per 100g, depending on preparation
- A protein powder made from whey or plant: around 20-25g per scoop
Distributing these foods throughout the day (3-4 meals), rather than all at once, will help to improve absorption and the ability to build muscle protein.
Signs You Might Not Be Meeting Your Daily Protein Intake
Some common symptoms of not getting enough protein per day are feeling hungry shortly after eating, not recovering from exercise, losing weight without understanding, fragile nails, and thinning hair. If you are seeing multiple of these signs, it would be beneficial to try and keep some sort of food log for a couple days and see how your protein intake compares to your target.
Common Mistakes People Make with Protein
- Not enough protein when losing weight: If you start to reduce calorie intake, but do not increase protein with it, this can result in losses of muscles that the body doesn't need.
- Too much protein without training: It's no use to eat a lot of protein without resistance training if you are not going to gain a lot of muscle.
- Overusing protein powders: Avoid using protein powders as your primary source of protein, and use them as a supplement instead.
- Failure to account for life stage change: Needs change throughout pregnancy, aging and with changes in activity levels, so a set target is seldom appropriate for all life stages.
Conclusion
The key to knowing your actual daily protein requirement is to not just take generic advice and determine a protein target based on your weight, activity level and goals. Most active adults need more protein than the basic prevention of protein deficiency, whether you are interested in daily protein recommendations for women, men or just how to figure out daily protein for yourself. Eating the protein-rich foods spread out evenly during the day and not fixating on a single "perfect" amount is the simplest approach to consistently get the protein you need.
FAQs
- How much is the daily recommended allowance of protein for the average adult?
Protein requirements are about 0.8g/kg/day for a sedentary adult, but higher for active individuals.
- How do I calculate my protein for daily intake based on my goals?
For protein daily requirements, divide your weight in kilograms by 0.8 to 2.2, depending on activity level and desired results (muscle building or weight loss).
- Are daily protein needs for women different from men?
The amount of protein required each day for women is determined using the same formula as men (based on body weight), but there are certain factors that may raise the individual's protein requirement, such as pregnancy, breastfeeding, and specific fitness goals.
- What is a good daily protein intake for men focused on muscle building?
For men of muscle building interest, protein consumption ranges from 1.6 to 2.2 g per kg of body weight, along with regular resistance exercise training.
- Can I get my full daily protein intake from vegetarian foods?
Absolutely, veggies can get sufficient protein from eating various foods at different meals, such as paneer, lentils, tofu and Greek yogurt.
