How much protein do i need for weight loss ? The precise amount of protein varies depending on your personal body weight and fitness goals. For example, if you have a goal to lose weight, the precise amount would be more than the one who wants to build lean muscle mass. To lose weight by dieting, you need to create a calorie deficit. A good way to do this is to cut back on your daily calories. You may also consider increasing your exercise level. Protein plays a role in weight loss. It reduces hunger, thereby helping you reduce calorie intake. This can prevent or slow down weight gain.
What are proteins made of?
Proteins are made up of many different amino acids linked together. There are twenty different of these amino acid building blocks commonly found in plants and animals. A typical protein is made up of 300 or more amino acids and the specific number and sequence of amino acids are unique to each protein. Rather like the alphabet, the amino acid ‘letters’ can be arranged in millions of different ways to create ‘words’ and an entire protein ‘language’. Depending on the number and sequence of amino acids, the resulting protein will fold into a specific shape. This shape is very important as it will determine the protein’s function (e.g. muscle or enzyme). Every species, including humans, has its own characteristic proteins.
Amino acids are classified as either essential or non-essential. As the name suggests, essential amino acids cannot be produced by the body and therefore must come from our diet. Whereas, non-essential amino acids can be produced by the body and therefore do not need to come from the diet.
What do proteins do for the body?
Our bodies are made up of thousands of different proteins, each with a specific function. They make up the structural components of our cells and tissues as well as manyenzymes,hormonesand the active proteins secreted fromimmune cells
These body proteins are continually being repaired and replaced throughout our lives. This process (known as ‘protein synthesis’) requires a continuous supply of amino acids. Although some amino acids can be recycled from the breakdown of old body proteins, this process is imperfect. This means we must eat dietary protein to keep up with our body’s amino acid demand.
As protein is essential forcelland tissue growth,adequate intakeof protein is particularly important during periods of rapid growth or increased demand, such aschildhood, adolescence,pregnancy, and breastfeeding.1
Is there a difference between animal and plant-based proteins?
As we can see , both animal and plant-based foods can be rich sources of protein. But do they have the same quality?
The quality of a protein can be defined in many ways; however, all definitions relate to the distribution and proportion of essential and non-essential amino acids they contain. In general, animal-based proteins are of higher quality as they contain higher proportions of essential amino acids compared to plant-based proteins.
There is a common misconception that plant-based proteins completely lack certain essential amino acids. In fact, most plant-based proteins will contain all 20 amino acids but tend to have a limited amount of certain essential amino acids, known as their limiting amino acid(s). This means, if a small number of plant foods are consumed as the only protein sources, they are unlikely to supply enough essential amino acids to meet our requirements. For people who consume little to no animal-based foods, such asvegans or vegetarians,it is important that they consume protein from sources with complementary limiting amino acids. For example, consuming rice (limited in lysine and thiamine but high in methionine) and beans (limited in methionine, but high in lysine and thiamine) will provide complementary amino acids that can help meetessential amino acidrequirements.
Animal and plant-based proteins also differ in theirbioavailabilityand digestibility. The digestible indispensable amino acid score (DIAAS) is the recommended method for determining dietary protein digestibility and is expressed in values below or sometimes even above 100.3A DIAAS of over 100 indicates that the protein has very high digestibility and quality and is a goodcomplementprotein to those that have lower qualities. Animal-based proteins tend to have higher DIAAS scores compared to plant-based proteins (Table 2). As most people consume protein from a variety of sources the quality and digestibility of protein is not usually a concern.
Benefits of a high-protein diet
While protein is an important building block of any healthy diet, committing to a high-protein diet comes with several science-backed benefits:
1. Reduces your appetite
Protein can help you to feel fuller for longer and reduce your appetite; a key benefit of a high-protein diet.
Your appetite is regulated by your brain, which is influenced by several satiety hormones. These tell your brain when and how much you should eat.Studiesshow that a high-protein diet increases the levels of 3 appetite-reducing hormones, whilst reducing the levels ofghrelin, a hormone that makes you feel hungry.
Protein also takes longer to digest than carbohydrates, adding to its appetite-reducing effect. Together, these factors can lead to a reduction in hunger, which can help you to eat fewer calories and lose weight.
2. Helps you to burn more calories
Protein has thehighest TEF(thermic effect of food) of all three macronutrients, which means it can help you to burn more calories.
The thermic effect of food (TEF) is the amount of energy that your body needs to digest and metabolize the food you eat. When you eat protein, 20–30% of the calories you consume are burned during digestion. This is significantly higher than carbs (5–10%) and fat (0–3%).
For perspective, if you were to 300 calories worth of protein, your body will use between 60 and 90 of them during digestion. This increased energy expenditure can help you to lose or maintain weight naturally.
3. Increases your muscle mass and strength
One of the key benefits of a high-protein diet is muscle growth. In those trying to lose weight, it can also help to promote fat loss whilst decreasing muscle loss.
When you lose weight, you’re likely to lose muscle as well as fat. This is because your body may transform muscle mass (as well as fat) into energy when you’re in a calorie deficit. But by providing your body with extra protein, you can ensure that there is enough to support both muscle health and your energy requirements.
In a2012 study, two groups of adults were put on a low-calorie diet. However, one included high-protein, while the other was low. At the end of the study, both groups lost a similar amount of weight, but the high-protein diet group managed to preserve significantly more lean muscle mass.
4. Strengthens your bones
A high-protein diet can help to strengthen bones and prevent osteoporosis.
Protein makes up 50% of your bone structure, aids in calcium absorption and provides key nutrients for bone health. For this reason, high-protein diets are increasingly linked with greater bone mass and fewer fractures, when combined with adequate calcium intake.
TheBritish Association of Dieteticsstates that eating enough protein—at least 2 servings per day—can help to safeguard your bones.
5. Improves sleep
One of the lesser-known benefits of a high-protein diet is that it can help to induce and improve your sleep.
Tryptophan, an amino acid found in most protein foods, boosts the sleep-regulating hormone melatonin. Tryptophan is found in most high-protein foods, especially dairy products, poultry, eggs and peanuts.
Studiesshow that consuming a serving of protein before you go to bed is associated with better sleep quality and can help you to wake up less through the night.
6. Promotes weight loss
Ultimately, eating a high-protein diet of 0.6 grams+ of protein per pound of body weight can be an effective weight-loss technique. Numerous factors sway heavily in protein’s favour when it comes to weight loss and maintenance, including:
- Protein reduces the levels of the hunger hormone ghrelin, which can help toreduce hunger.
- Protein has a high thermic effect (TEF), which means you’llnaturally burn more calorieswhilst digesting your meals.
- Protein helps you tolose body fatbutreduces muscle loss(particularly when combined with strength training).
- Protein is the most satiating macronutrient, which means you’llfeel fuller for longerandexperience fewer food cravings.
How do I calculate my protein by calorie?
Now it’s time that we get to do a little bit of math, and find out more about how we handle our protein intake with our overall caloric intake. Let’s think about it this way:
- Our total calories for the day are 1800.
- The total amount of protein (in grams) for the day is 60.
- To find the total calories from protein, we have to multiply protein grams by 4.5 (which gives us 270).
- Then we divide protein calories by total calories – so, 270 divided by 1800 is 15% protein calories.
Because women consume fewer total calories than men, reaching 25-30% can sometimes be a bit more challenging. It is often more common that they supplement with protein powders to reach their targets, without getting too much food into their systems.
In Conclusion:Figuring out your protein per calorie is going to be so important. Therefore, you are going to want to make sure that you keep track of all the foods you are putting into your system on a given day. Keep track, do not guess when it comes to your health and your body!
Which foods are protein dense?
When we talk about protein, we want to get to the heart of the issue – with the kinds of foods that are the most protein dense for our diet. We want to focus on foods which have a higher protein per calorie ratio.
This might look a bit similar, compared to our earlier list, but let’s run through it again:
- Seafood and shellfish
- Eggs and egg whites
- Soy foods
- Protein powder
For dairy, there are only two:
- Cottage cheese
- Non-fat unsweetened Greek yogurt
What you might have noticed was the lack of nuts, seeds, beans, legumes, grains and other forms of dairy – where did they go? While they might be sources of protein, they are not the best sources of protein per calorie for our diets.
While beans might make for a good carb, and seeds make for a good fat, they might not always make for a good protein. So, we do not want to focus on them when we are trying to talk about the truly protein dense foods out there.
Calculate protein requirement by weight
