High-quality animal protein is the original superfood that plays a pivotal role in health. A recent study published in the Journal of Nutrition concluded that adults need to source 45 to 60 percent of their total proteins from animals to ensure sufficient levels of other nutrients.

red meat is even more nutrient-dense than chicken or fish. The combination of protein and all the other vitamins and minerals makes red meat a particularly bioavailable food that supports muscle health. While all animal-based proteins are highly bioavailable, red meat is one of the best dietary muscle meat sources of iron and B vitamins.

When it comes to calculating our dietary protein intake, the real task is ensuring a proper balance of AAs absorbed through different food sources.

We need three different types of AAs to maintain overall health: Nonessential amino acids. Your body has the ability to synthesize these on its own. Conditionally essential amino acids. In times of injury or illness, your body cannot make enough of these and relies on dietary sources. Essential amino acids. These come directly from your diet.

three are uniquely important in characterizing food quality: leucine, lysine, and methionine. These work best when consumed together, and of these three, leucine is the most important for muscle health.

studies on older adults have shown that older people can experience a “restorative” effect on MPS from consuming at least 2.5 grams of leucine per meal. That restorative level requires a minimum of 30 grams of high-quality protein at each meal.

PROTEIN POWER MOVES Eat your protein first. This will make sure you take in the AAs that drive MPS, and it will help you feel full sooner. Before you attend an event offering unhealthy food, drink a 20-gram protein shake. Replace salty, crunchy snack foods with Carnivore Crisps or other protein chips. Balance a low-protein meal by throwing a packet of AAs into your water. This can help activate your muscle metabolism and lower a spike in blood sugar.6

Although some say total daily protein is most important, the literature suggests that distributing protein throughout the day is the optimal strategy for building and maintaining muscle.

Are you trying to gain muscle? Then, depending on your target daily total, you can increase your protein intake to four, five, or even six times a day.

It’s more effective to increase your total number of meals than to eat more protein at a single meal. For example, if your protein goal is 200 grams a day, and you’ve already planned three meals containing at least 40 grams of protein each, you should add an extra meal.

When it comes to making muscle, breakfast is by far the most important meal. By breakfast, I mean your first meal of the day, whenever that is. A robust dose of protein, first thing, will set you up for metabolic optimization, priming your body by stimulating muscle growth, reducing hunger, and supplying you with an AA dose to use for other biological processes. The second most important meal is the last one before your overnight fast. Choosing foods that provide your body with sufficient AAs to generate glucose can help stabilize blood sugar through the night and prep you for the morning. The ...more

Because of the fates of AAs within your body, it takes more energy to metabolize protein than carbs or fat.

say you’re maintaining a 2,000-calorie diet, and 800 of those calories come from protein; the digestion and assimilation of that protein will result in the burning of 160 to 240 calories. This is like consuming 20 to 35 percent less than the total protein calories tallied from your food labels.

Although it’s true that we don’t need to consume carbohydrates to provide glucose as part of a healthy diet, we do need fiber.

With my plan, two practical relationships drive dietary decision-making: the ratio of carbs to protein and the ratio of carbs to fiber. The carb-to-protein ratio defines how many grams of carbohydrates you can have at a meal and still maintain metabolic balance. To promote weight loss, your overall dietary carb-to-protein ratio should be less than 1.0,

I also recommend that you never eat carbs alone; instead, combine them with either fat or preferably protein, ideally at least 10 grams. I always recommend that you “preload” with protein or fats before eating carbohydrates.

Foods with a carb-to-fiber ratio of less than six have a low glycemic load and high levels of fiber. (A ratio of 8:1 offers a bit more flexibility for those who tolerate carbs such as whole grains and starchier vegetables for a little more nutrient diversity.)

Here are some examples of high-fiber carbs that I recommend based on these ratios: 1 cup of broccoli contains about 7.8 grams of carbs and 4.6 grams of fiber. Doing the math (7.8/4.6 = 1.7) shows a carb-to-fiber ratio for broccoli of 1.7. For green beans, the ratio is 2.5. Raspberries, 1.7. Strawberries, 3.1. Blueberries, 5.1. Most beans, 3.0.

To make resistant starch rice, cook white rice with a fat source like olive oil and then, after it’s done cooking, cool the rice in the fridge. Together, the addition of fat and the cooling process catalyze the formation of resistant starch from the once simple starches present in this food.4 The same can be done for potatoes, except the fat is added after cooking, followed by cooling.5

The key is to ensure that your body uses all that you take in. Being able to get rid of the carbs we eat is called postprandial glucose clearance. This critical factor establishes our carbohydrate meal tolerance. To avoid post-meal elevations in blood glucose, or hyperglycemia, a carbohydrate meal must be efficiently cleared within two hours.

Fat is a very efficient fuel for skeletal muscle, and individual fatty acids are essential for every cell membrane—especially the unique protective layer around nerve structures in our brains. This makes fatty acids an essential requirement, but the minimum amount we need is very low, only about 3 grams of essential fatty acids per day. Diet-wise, that translates to eating between 25 and 35 percent of our daily calories from fat to get the minimum 3 grams of essential fatty acids.
