Enter your age, weight, and exercise degree, and the Legion Protein Calculator will let you know precisely how a lot protein you should eat per day to shed pounds, construct muscle, or preserve your physique.
What Is Protein?
Protein is a macronutrient important for constructing, repairing, and sustaining tissues in your physique, together with muscular tissues, pores and skin, and organs.
It’s made up of amino acids—the “constructing blocks” your physique makes use of to develop and restore cells.
Protein additionally performs a key position in varied bodily capabilities, reminiscent of producing hormones, supporting immune perform, and offering vitality when wanted.
There are 20 amino acids that comprise the protein in your physique. Your physique can produce 11 amino acids by itself, but it surely should get the remaining 9 out of your food regimen, which is why consuming protein is significant for all times.
How A lot Protein Do I Want? Calculator Outcomes Defined
The present Advisable Dietary Allowance (RDA) for protein within the US is 0.8 grams per kilogram of physique weight per day, or about 0.36 grams per pound of physique weight per day.
That stated, a big physique of proof exhibits that that is insufficient for sustaining or constructing muscle mass, optimizing fats loss, and maximizing your well being and efficiency, particularly if you happen to’re lively.
What’s extra, current proof means that even the present RDA could also be inadequate for supporting well being, and that it ought to be adjusted upward to 1.0 g/kg/day, or about 0.45 g/lb/day.
For instance, in a examine printed within the British Journal of Diet, wholesome, sedentary adults ate 40% extra energy than they wanted to keep up their weight and three totally different quantities of protein: 0.7 g/kg (a tad lower than the RDA), 1.8 g/kg, and three.0 g/kg.
The individuals who consumed the RDA of protein misplaced muscle mass regardless of being in a calorie surplus, whereas the individuals who ate extra protein gained muscle.
That stated, consuming as a lot protein as doable isn’t higher. Whereas research present it’s suitable for eating 1.5-to-2+ grams of protein per pound of physique weight per day, this isn’t essential to optimize muscle development, fats loss, or well being.
RELATED: Is Excessive-Protein Weight-reduction plan Dangerous for Your Kidneys?
In different phrases, consuming a really high-protein food regimen (greater than 1 g/lb/day) isn’t “dangerous,” however analysis exhibits it most likely isn’t any higher than consuming a reasonable quantity of protein (0.8-to-1 g/lb/day).
Many health people intentionally eat slightly extra protein than analysis exhibits is critical as a approach to make sure they aren’t lacking out on any of its advantages. For instance, as a substitute of consuming 0.8 g/lb/day, which for a 200-pound man can be 160 grams of protein, they select to eat 1 g/lb/day, which is 200 grams.
This solely provides 160 energy to their day by day meals consumption, so it doesn’t meaningfully cut back how a lot carbohydrate and fats they’ll eat per day.
What you don’t need to do is eat a lot extra protein that you must considerably cut back your carbohydrate and fats consumption, as this may negatively influence your exercise efficiency, restoration, and hormonal well being.
Our protein calculator makes use of this up-to-date science to place you within the Goldilocks zone for protein consumption—sufficient to maximise fats loss, muscle achieve, and satiety, whereas nonetheless leaving ample room for carbs and fats in your food regimen.
The Advantages of Utilizing the Legion Protein Calculator for Weight Loss

Should you’re attempting to lose fats whereas minimizing muscle loss, analysis exhibits it’s best to eat between 0.5-to-1 grams of protein per pound of physique weight per day.
Should you’re lifting weights or doing a number of arduous or extended exercises per week, reminiscent of working, martial arts, or staff sports activities, you then’ll need to goal for the higher finish of this vary—round 0.8-to-1 grams of protein per pound of physique weight per day.
Should you’re bodily lively, however aren’t lifting weights or doing vigorous or extended exercises, and aren’t attempting to shed pounds, then you will get by with much less protein—round 0.5-to-0.7 grams of protein per pound of physique weight per day.
And if you happen to’re sedentary (which isn’t best if you wish to maintain your well being), analysis exhibits you’ll be able to eat as little as 0.4 grams of protein per pound of physique weight per day with out shedding muscle.
Except for preserving muscle mass, another excuse to eat extra protein than the RDA is that it improves satiety, which makes it simpler to keep up a calorie deficit.
Protein additionally “prices” extra energy to digest than carbohydrate and fats, and so consuming extra protein barely boosts metabolic price (although the impact isn’t sufficient to have a significant influence on weight reduction).
Some protein calculators advocate a lot larger intakes than this—all the best way as much as 1.5 g/lb per day or extra. These options are primarily based on outdated analysis (or simply good ol’ long-established broscience), which overestimated the quantity of protein you should forestall muscle loss whereas weight-reduction plan.
Newer research have proven that these suggestions are extreme and may make weight-reduction plan tougher by decreasing the energy out there for carbs and fat.
Whereas it’s tremendous to eat barely extra protein than essential “simply in case,” consuming an excessive amount of could make weight-reduction plan tougher and ugly by limiting your meals choices.
Should you eat so a lot protein that you must severely prohibit your carbohydrate and fats consumption, this may additionally damage exercise efficiency, restoration, and hormonal well being.
Thus, when attempting to shed pounds, you need to eat sufficient protein to protect muscle and keep happy between meals, however not far more than this.
Protein is only one piece of the fats loss puzzle, although. You additionally must eat the appropriate variety of energy and the appropriate steadiness of carbs and fats. For customized recommendation on energy and macros, try our macronutrient calculator:

The Advantages of Utilizing the Legion Protein Calculator for Muscle Acquire

In case your purpose is to achieve muscle, it’s important that you just eat a high-protein food regimen.
Analysis exhibits that growing protein consumption past the RDA considerably will increase muscle development, particularly when mixed with energy coaching.
For instance, a meta-analysis of 49 research discovered that consuming 0.7-to-0.8 grams of protein per pound of physique weight per day optimizes muscle achieve for weightlifters.
Your physique’s potential to make use of protein for muscle constructing hits a ceiling round this level, although, so consuming extra doesn’t result in a lot if any extra muscle achieve.
That stated, your protein wants could also be barely larger relying on components like your genetics, exercise degree, coaching quantity, and weightlifting expertise, which is why many individuals attempting to achieve muscle select to eat barely extra—sometimes round 1 gram of protein per pound of physique weight per day.
Should you’re not sure in regards to the actual quantity of protein to construct muscle, our calculator can provide you customized suggestions primarily based on the most recent analysis.
In fact, protein alone received’t get you the outcomes you’re after. That you must comply with a well-rounded food regimen with the appropriate steadiness of carbs, fats, and energy mixed with an efficient energy coaching plan to optimize muscle development.

The right way to Use the Legion Protein Calculator for Seniors
Analysis exhibits that folks over 60 years previous ought to eat a minimal of 0.5-to-0.8 grams of protein per pound of physique weight per day, relying on their exercise degree.
The decrease finish is normally enough for stopping muscle loss in sedentary individuals, whereas the upper finish is useful for maximizing muscle achieve and upkeep for older people who raise weights.
As we age, sustaining muscle mass and energy turns into more and more essential—it helps us keep cell, lowers the chance of falls and fractures, and reduces the probability of sickness and frailty.
Analysis persistently exhibits that protein performs a vital position on this course of.
As an example, a meta-analysis of seven research discovered that older adults who consumed greater than 0.5 grams of protein per pound of physique weight per day maintained higher mobility, whereas these consuming much less skilled higher muscle loss and frailty.
One other systematic evaluation printed within the Journal of the American Faculty of Diet confirmed that seniors who ate extra protein than the RDA (0.4 g/lb/day) considerably diminished their danger of hip fractures, which highlights the position of protein in bone well being.
Increased protein intakes additionally cut back the chance of persistent illnesses.
A examine printed in The American Journal of Medical Diet tracked 50,000 individuals over 30 years and located that older people who consumed as much as 23% of their day by day energy from protein had been much less prone to develop persistent illnesses like coronary heart illness, diabetes, or most cancers. Additionally they maintained higher cognitive and bodily perform.
For each 3% enhance in whole protein consumption, the examine confirmed a 5% relative enchancment within the probability of getting old with out persistent sickness.
Use our protein per day calculator to simply discover your optimum day by day protein consumption that can assist you keep robust and important as you age.
The right way to Meet Your Day by day Protein Objective

Listed below are three sensible tricks to persistently hit your day by day protein goal:
- Eat 30-to-40 grams of protein per meal. One of the simplest ways to satisfy your day by day protein wants is to be sure you eat 3-to-4 meals with 30-to-40 grams of protein in every. Should you do that, it’s arduous not to get near your day by day protein goal every single day.
- Complement with protein powder, bars, and cookies. Whenever you’re on-the-go or simply don’t really feel like making ready or consuming regular meals, protein powder, bars, and cookies are a handy and attractive technique to enhance your protein consumption.
- Snack on high-protein meals: Preserve high-protein snacks readily available for in-between meals. Skyr, Greek yogurt, cottage cheese, jerky, meat sticks, hard-boiled eggs, and edamame are all good choices that require minimal prep.
What Are the Finest Excessive-Protein Meals?
Under are a few of the greatest meals for making ready high-protein meals.
- Poultry: Rooster breast, turkey breast, floor turkey, hen thighs.
- Pink Meat: Floor beef (90% lean or larger), prime sirloin steak, pork tenderloin, pork chops, bison, lamb.
- Fish: Tuna, salmon, cod, mackerel, halibut, sardines.
- Shellfish: Shrimp, crab, lobster, scallops, clams, mussels.
- Eggs: Complete eggs and egg whites.
- Low-Fats Dairy: Low-fat milk, Greek yogurt, Skyr, cottage cheese, low-fat cheese (mozzarella, Swiss), kefir.
- Legumes: Black beans, lentils (purple, inexperienced, or brown), chickpeas, kidney beans, pinto beans, edamame, peas.
- Complete Grains: Brown rice, quinoa, millet, farro, barley, buckwheat, bulgur.
- Nuts and Seeds: Almonds, cashews, pistachios, walnuts, hemp seeds, chia seeds, flaxseeds, sunflower seeds, pumpkin seeds, sesame seeds.
- Greens: Broccoli, cauliflower, Brussels sprouts, asparagus, spinach, kale, inexperienced peas, edamame.
How A lot Protein Can Your Physique Soak up In a Single Meal?
Your physique can take up and successfully use 100 or extra grams of protein in a single meal.
That stated, most analysis exhibits that you’ll maximize the muscle-building advantages of protein if you happen to divide your day by day protein consumption throughout 3-to-4 meals per day, not less than 3 hours aside, with not less than 20-to-30 grams of protein in every meal.
It’s because consuming protein will increase muscle protein synthesis (the creation of recent muscle proteins), and reduces muscle protein breakdown (the breakdown of muscle proteins).
This impact solely lasts for a number of hours, although, which is why it’s best to devour a number of protein-rich meals all through the day, which boosts protein synthesis and suppresses protein breakdown for so long as doable.
