Go ahead — buck the trend, be fearless and follow that high-protein diet. Here's why science supports eating plenty of this essential macronutrient to hit your get-lean strong-body goals — and two meal plans to get you started.
Ask 10 people in the gym how they prefer to eat — for gains, to get lean or for performance — and you’ll get 10 different answers. And every month, there is a new diet or nutrition fad that everyone jumps to follow — keto, Paleo, Whole30 and the like. But one style seems to get the brunt of the negative press, and myths about its veracity perpetuate, no matter how much research is done to disprove them — eating high-protein.
Depending on who you ask (or follow on social media), anything above and beyond the Recommended Daily Allowance for protein will cause liver and kidney damage, overtax your digestive system, and even cause you to instantly gain body fat by eating more than your fair share of chicken in one sitting. So what is hype and what is truth? How much protein can — or should — you eat in order to stay healthy and still hit your goals? Read on to find out.
The most prevalent myth about eating high-protein is that it is hard on your kidneys, or worse, that it actually causes liver and kidney damage. Second only to the organ-murdering effects of a high-protein diet is the idea that any excess protein you eat quickly turns into body fat. Even though research has proved time and again that these concepts are false, for some reason, they persist. Here’s the real scoop.
Protein is one of only three macronutrients that constitutes your diet — the other two being carbs and fat — and is composed of amino acids, the fundamental building blocks of muscle that are also essential components for basic cellular function. Since your body can’t store protein as it does carbs and fat, it’s important to continuously replenish your supply of amino acids by eating plenty of protein every day. But is there a limit as to what your body can handle? Nope.
Research has shown that there’s no absolute upper limit to protein intake and no indication that you will incur irreparable damage to your organs or physique if you eat more than the RDA of 0.8 g/kg of bodyweight. Case in point: A study published in the Journal of the International Society of Sports Nutrition found that those eating a very high-protein diet (4.4 g/kg/day) showed no ill effects on body composition, organ function or overall health. Take that in a moment: Consuming more than five times the RDA for protein had no negative effects and did not cause any gains in body fat.
Eating a high-protein diet doesn't mean eating a side of beef in one sitting. You can calculate your protein needs with the equation at the bottom of this article.
Obviously, you should not go out and eat a side of beef in one sitting, but it bears remembering that the RDA for protein is just a baseline and represents the bare minimum needed to prevent illness and/or malnutrition. For athletes, there are other considerations that come into play, depending on your strength and building-muscle and endurance goals, and this demographic, most experts agree, should take in between 1.6 and 2.2 g/kg of protein per day broken up between three to four meals, or about 20 to 30 grams of protein per meal.
Animal vs. Plant-Based Proteins
The two biggest factors that determine protein quality are digestibility and amino-acid profile, and any source — animal or plant-based — that contains all the amino acids your body needs are considered complete proteins. All animal proteins are complete, whereas many plant-based options are incomplete, meaning they lack one or more essential amino acids.
However, following a plant-based lifestyle does not inhibit you from eating a complete amino-acid profile — you’ll just have to work a little harder for it. As long as you’re getting a variety of plant-based protein sources throughout the day, you should fulfill all your amino-acid needs and hit your daily protein totals.
Try the High-Pro Approach
These two-week, high-protein meal plans were designed with athletic women in mind and can maximize your strength and muscle-building potential while supporting your lean-body goals. Choose your path — animal-based or lacto-ovo — and follow the prescribed meal plan. If you prefer to stay completely away from animal-based proteins, simply replace those with plant-based options like soy, tofu, tempeh and plant-based protein powders of equal protein value.

CALCULATE YOUR NEEDS
How much protein do you need? Use this calculation to find out.
(Your bodyweight) ÷ 2.2 = weight in kilograms
(weight in kilograms x 1.6) to (weight in kilograms x 2.2)
= grams of protein needed per day
So a woman who weighs 135 pounds (61.36 kilograms) would need between 98 and 134 grams of protein per day, or 24 to 33 grams of protein per each of four meals.
