Food Labeling Reference Tables
Daily Values used by the FDA for the following macronutrients are Daily Reference Values.
The FDA issued a final rule on changes to the facts panel on May 27, 2016. The new values were published in the Federal Register. The original deadline to be in compliance was July 28, 2018, but on May 4, 2018, the FDA released a final rule that extended the deadline to January 1, 2020, for manufacturers with $10 million or more in annual food sales, and by January 1, 2021, for manufacturers with less than $10 million in annual food sales. During the first six months following the January 1, 2020 compliance date, the FDA worked cooperatively with manufacturers to meet the new Nutrition Facts label requirements and did not focus on enforcement actions regarding these requirements during that time. Due to lengthy shelf-life on certain food items, products containing old or new facts panel content may be on market shelves at the same time.
The following table lists the old and new DVs based on a caloric intake of 2000 kcal , for adults and children four or more years of age.
How To Calculate Your Daily Protein Intake
Knowing protein is such an important nutrient for those looking to lose weight while maintaining or even building muscle, you may wonder exactly how much protein you should be consuming each day. The previously mentioned 0.8 grams per kilograms of bodyweight per day, which translates to about 0.36 grams of protein per pound, is a decent starting point.
However, most people who are looking to lose weight and are focused on a high protein diet will likely want to increase that ratio. An article published by Harvard Medical School last year called the 0.8 grams of protein per kilograms of bodyweight ratio modest, pointing out that following the RDA would result in only about 10% of daily calories coming from protein sources. It further suggests that consuming between 15% and 25% of your daily calories from protein sources can be beneficial to help you with muscle growth and retention.
A ratio of anywhere from 0.4 grams of protein per pound to as high as 0.7 grams per pound is typically used by professional athletes or others who engage in lots of exercise. Experiment with different ranges to see what kind of protein intake your body needs to help you feel full enough to achieve your weight loss goals.

How Much Protein Do You Need For Weight Loss And Muscle Growth
Low-carb, vegetarian, Mediterraneanwhatever your diet, its important to get enough protein.
Although research hasnt yet pinpointed one perfect formula, experts say that the typical recommended daily minimums arent optimal, and that it helps to factor in your weight and activity level to determine how much protein you personally need.
A good baseline for people who exercise at a moderate level is between one-half and three-quarters of a gram of protein per pound of bodyweight. If you weigh 150 pounds, for example, eat between 75 and 112 grams of protein per day. To lose weight, diets with higher amounts of proteinbetween 90 and 150 grams a dayare effective and help keep you from losing muscle along with fat.
Since the body uses protein most effectively when you have it at regular intervals, divide your daily intake into four equal amounts for breakfast, lunch, a snack and dinner. If you work out at a high level, consider eating another 50 grams of protein before you go to bed to help with overnight muscle repair.
You might be familiar with calorie counting, but its also important to know how to tally your protein intake. While one ounce of chicken weighs 28 grams, it contains only about 9 grams of protein. So it takes a 3-ounce portion to deliver 27 grams of protein, or about one-quarter of the average daily need.

Getting More Protein Into Your Day Naturally
If youre looking for ways to get more protein into your diet, here are some suggestions:
- Try a peanut butter sandwich. Remember to use natural peanut butter with no added salt, sugar or other fillers.
- Low-fat cottage or ricotta cheese is high in protein and can go in your scrambled eggs, casserole, mashed potato or pasta dish. Or spread it on your toast in the morning.
- Nuts and seeds are fantastic in salads, with vegetables and served on top of curries. Try toasting some pine nuts or flaked almonds and putting them in your green salad.
- Beans are great in soups, casseroles, and pasta sauces. Try tipping a drained can of cannellini beans into your favourite vegetable soup recipe or casserole.
- A plate of hummus and freshly cut vegetable sticks as a snack or hummus spread on your sandwich will give you easy extra protein at lunchtime.
- Greek yoghurt is a protein rich food that you can use throughout the day. Add some on your favourite breakfast cereal, put a spoonful on top of a bowl of pumpkin soup or serve it as dessert with some fresh fruit.
- Eggs are a versatile and easy option that can be enjoyed on their own or mixed in a variety of dishes.
Optimal Daily Protein Intake For Healthy Sedentary Adults
For adults, the US Recommended Dietary Allowance for protein is 0.8 g/kg. However, a more appropriate statistical analysis of the data used to establish the RDA suggests this number should be higher: 1.0 g/kg.
Note that, contrary to popular belief, the RDA doesnt represent an ideal intake. Instead, it represents the minimum intake needed to prevent malnutrition. Unfortunately, the RDA for protein was determined from nitrogen balance studies, which require that people eat experimental diets for weeks before measurements are taken. This provides ample time for the body to adapt to low protein intakes by down-regulating processes that are not necessary for survival but are necessary for optimal health, such as protein turnover and immune function.
An alternative method for determining protein requirements, called the Indicator Amino Acid Oxidation technique, overcomes many of the shortcomings of nitrogen balance studies. Notably, it allows for the assessment of protein requirements within 24 hours, thereby not leaving the body enough time to adapt. Studies using the IAAO method have suggested that about 1.2 g/kg is a more appropriate RDA for healthy young men, older men, and older women.
Further evidence that the current RDA for protein is not sufficient comes from a randomized controlled trial that confined healthy, sedentary adults to a metabolic ward for eight weeks. The participants were randomized into three groups:

Here’s Exactly Why You Need Protein
Protein is vital to life: Its made from amino acids that are essential for building and maintaining muscles and bones. In addition, recent studies suggest that protein quality, or the total makeup of amino acids within a protein source, may become more important as you age.
But beyond your infrastructure, protein also helps to regulate a host of cellular processes, affecting everything from your immune function to the transportation of oxygen through the bloodstream. Protein can even aid in weight loss: Researchers have found that consuming it stimulates the release of satiety signals in the small intestine, helping you feel full.
In short, protein is a super-nutrient. A do-it-all. A power player in how you use your body and what it looks like.
Protein is important. In fact, its vital for building the body you want. Protein helps , builds and maintains muscle, fortifies your bones, improves brain function, aids your immune system, and can even pick up the kids from soccer practice if youre strapped for time.
We digested the past 25 years of nutrition knowledge, talked to the smartest experts about the latest science, and sorted through a lot of nutrition B.S.all to provide you with the most up-to-date information about protein right now.
Optimal Daily Protein Intake For Lactating Women
As with pregnancy, there is little research investigating how lactation and breastfeeding affect protein requirements. Women produce a wide range of breast milk volumes, regardless of their energy status . The infants demands appear to be the primary regulator of milk production.
Based simply on adult protein requirements plus the protein output in breast milk, the RDA for lactating women was set at 1.3 g/kg. However, one study reported that half of the lactating women consuming 1.5 g/kg were in negative nitrogen balance, while another study suggested that 1.01.5 g/kg leads to a rapid downregulation of protein turnover suggestive of an adaptive response to insufficient intake.
Considering the lack of data on the effects of a protein intake greater than 1.5 g/kg in lactating women and that consuming 1.5 g/kg or less leads to adaptations suggestive of insufficient intake, lactating women should aim to consume at least 1.5 g/kg of protein daily.

Increase Protein For Weight Loss
A June 2017 study published in Obesity Facts found that adults who followed a high-protein diet and stuck to it lost significantly more weight than adults who just reduced their calorie intake. This suggests that if you are trying to lose weight, cutting calories alone is not as effective as cutting calories and increasing your daily protein intake.
Additionally, an August 2018 study in Frontiers in Endocrinology notes that protein may be the key to weight management because eating protein makes you feel fuller longer. It also promotes the body’s energy expenditure or calorie burn, and helps change the body composition in favor of lower fat body mass.
In general, the American College of Sports Medicine makes the following daily protein recommendations, saying that 10 to 35 percent of your daily calorie intake should come from protein. The Recommended Dietary Allowance â which refers to what healthy people need to intake on average per day to meet their nutrient requirements and is based solely on weight â says you need to eat 0.35 grams of protein per pound of body weight.

How Many Grams Of Protein Should I Eat A Day
Heads up: When we say grams, what were referring to are the grams of the macronutrient protein and *not* the foods it comes from. For example, one large egg weighs about 50 g, but only provides a little over 6 g of protein.
When it comes to the total amount of protein you need, the current international Recommended Dietary Allowance for both men and women is 0.8 grams per kilogram of body weight .
This means a 150-lb. person would require about 54 g of protein while a 200-lb. individual would need 72 g.
This RDA is only the minimum to avoid a protein deficiency. Certain peeps often require more protein, including:
The Science Of Protein
- Protein is a macronutrient that we need for growth, repair and maintenance in the body, especially for bones and muscles. Our protein needs change across the life course.
- Protein is an energy source and provides 4kcal per gram.
- In the UK, average intakes of protein are above the Reference Nutrient Intake including in vegetarians and vegans.
- The RNI is 0.75g of protein per kg bodyweight per day for average-weight adults .
- Top contributors to protein intakes in the UK are meat and meat products, cereals and cereal products and milk and milk products.
- It is important for health to include a range of protein-containing foods and we are recommended to eat more plant-derived protein foods.
- People who do some physical activity, like going for a run or to an exercise class are unlikely to need any extra protein. For people exercising at a high level, having some protein soon after a training session can help muscles rebuild.

The Daily Protein Rule
The general protein rule that many people who are serious about building muscle follow is 1g of protein per pound of body weight per day. This is somewhat close to what the most active of individuals looking to build muscle should follow. The chart below illustrates the scale of protein to body weight:
|Table 1: Recommended Grams of Protein Per Day Based on Body Weight|
Too Much Vs Too Little
According to the U.S. Department of Agriculture, the recommended daily intake of protein for adults at an average weight and activity level is 56 grams daily for men and 46 grams daily for women. This is the minimum required protein intake, and the amount can increase depending on your goals.
Its ideal to eat smaller amounts of protein throughout the day instead of getting your protein requirement in one or two meals. This allows your body utilize what it needs throughout the day instead of storing what isnt used as fat.
Its true that eating very high levels of protein is correlated with some health risks. If youre not cutting calories from carbohydrates while increasing calorie intake from protein, you may experience weight gain instead of weight loss.
Very high protein intake may also cause digestive issues, including constipation, gut-related issues and changes in blood sugar levels.
Finally, its important to maintain a healthy, well-balanced diet that doesnt completely neglect any nutrients. This will ensure that youre getting the micro- and macronutrients you need for optimal health.

Should You Take Protein Before Bed
The elderly, as well as people looking to build muscle, increase strength and improve exercise performance and recovery, can benefit from taking protein before bed .
In a review of studies, scientists concluded that taking protein before bed is an effective strategy to promote muscle building and help them adapt to exercise .
This is because protein consumed before bed is effectively digested and absorbed, increasing the availability of protein to muscles for recovery throughout the night.
Scientists from that study recommended consuming 40 grams of protein prior to bed to maximize muscle growth and adaptation through the night .
In another study in 16 healthy elderly men, half the participants consumed casein protein before bed, while the other half consumed a placebo. The study showed consuming casein protein before bed promoted muscle growth, even in less active elderly people .
If you want to take protein before bed, you may consider taking a form of casein protein. Casein is digested slowly, which means it can provide the body with a steady supply of protein through the night .
You can also get the benefits of casein protein from real foods instead of supplements. Dairy products like cottage cheese and Greek yogurt are high in casein.

Guidelines For Special Populations
Many sources that suggest protein guidelines provide numbers for adult men and women. But there are certain populations that may need more or less protein to manage a medical condition or facilitate growth.
- Pregnant and lactating people need more protein than people who are not pregnant .
- Older adults may need more protein than middle-aged adults .
- People with liver or kidney disease need to decrease protein intake .
Consult a doctor or dietitian to determine your ideal daily protein goal.

How Much Protein Do I Need
Protein is an essential nutrient. You have protein in every single cell in your body. Proteins do more than help you build toned muscles. They play an important role in the health of your hair, skin, nails, and your connective tissues. Antibodies are proteins that are critical to your immune system function. Proteins play a role in hundreds of bodily functions that are necessary to keep you healthy. Its safe to say that proteins are a critical component of a healthy diet.
Our bodies do not store protein, so we need to eat protein every day to maintain our health. The minimum amount of protein that you should eat each day is known as the Recommended Daily Allowance, or RDA. The RDA is the amount of nutrient that you need to eat to make sure you dont get sick. The RDA for protein for most adults is 0.8 grams per kilogram of your body weight. If the metric calculations arent your thing, you can figure out your RDA by multiplying your weight in pounds by 0.36. Using either method of calculation, youll find that a person who weighs 150 pounds would need about 54 grams of protein per day.
Keep in mind: the RDA is the minimum amount of protein that is recommended each day. Depending on your lifestyle and health goals, you may need or want to eat more protein.
