Importance of Protein at Old Age

People at this age most commonly face the problems of osteoporosis and muscle mass reduction, which is also known as sarcopenia. Protein helps in prevention of both of the issues in elderly people.

Protein repairs the damaged tissues or worn-out cells. In humans, after the age from 18 to 22 the organs develop to their full growth. After full development, the body cells or tissues need protein to mainly compensate the loss incidental. The toxicity in our body is responsible for occurrence of waste, deterioration of tissues, and degeneration of cells. If we follow a healthy lifestyle and consume a diet that supplies minimal toxins, we can significantly decline the rate of tissue waste, and so the needed amount of protein.

Protein for Weight Loss or Weight Gain

This amazing nutrient plays a vital role in both weight loss and weight gain, so you can’t at all afford to avoid protein in your diet.

Protein Use in Weight Loss

In the state of hunger or even craving, protein gives you much more satisfaction than fat or carbohydrates. You feel satiated after consuming protein-rich food, feeling fullness. It also helps you in getting rid of late night snacking and feeling lesser obsession about eating or food thoughts.

Protein boosts the rate of metabolism and reduces the appetite. For this boost, about 25 to 30% of protein calories work best. This protein consumption reduces your appetite decreasing the rate of calorie intake.

So this way, it helps you to lose weight, preventing from gaining extra pounds.

The Bottom Line

Add protein to your diet in appropriate amount, that is, about 30% of calories can be an optimal diet plan for weight loss or weight management.

For example, if you are following the 2000 calorie per day rule, about 150 grams of protein per day can help you a lot.

Warnings: Can High Protein Give Adverse Effects on Health?

Don’t overdo. Don’t start relying on just protein for fuel or energy. People who want to lose weight or build muscles or want a perfect body, they often mistake while following ‘low carb high protein’ diet. Too much use of protein is going to take you nowhere.

Lack of carbohydrate means our body needs to depend on the stored protein of our body. And protein breaking into carbohydrate and then into energy is a too strenuous job which gives extra burden to your liver and kidney. So don’t forget to go for ‘right’ amount.

High protein is recommended to avoid if you already have kidney related problems, but it is not so that if you have a healthy body and you are taking high protein then you will end up at kidney damage. The studies and research say this theory a myth that higher proteins affect your body adversely, but this is also right only when you are taking other nutrients in balanced amount and performing physical activities in coordination to your diet plan.

Nutrients are essential and play wonder if introduced to your food and diet plan, but beware! Measured quantity is the key to get the optimum results. Otherwise, the things can be disastrous too.

Protein Requirement: Does Too Much Protein Consumption Helps More?

The benefits of protein in developing muscles, protecting from diseases, the growth of hair motivates to consume protein. But beware! Excessive intake of protein can prove to be harmful too. It might increase your body fat. Overconsumption can also give overstrain to your liver and kidney. So take adequate protein in your diet, but do not over-take. Stick to fulfill the daily body requirement of protein! This is the best approach to follow.

Protein Use in Muscle Gain and in Building Muscle Strength

Our body is made of muscles; muscles are made of many tissues that contain largel protein. These tissues constantly break and again rebuild.

To build muscles, our body needs to build more tissues than they are breaking. So we need to take more protein than what our body is consuming in tissue formation, repair and replacement process.

As protein contains nitrogen abundantly, we can say we need to make net protein balance or net nitrogen balance.

The above mechanism is the reason that people advise to intake protein in the greater amount as higher protein eating helps building muscles and gaining strength.

Proteins are recommended for those also who have already built body muscles, but want to lose some body fat, holding muscles. High protein saves you from losing muscles when dieting Is on.

How Much Protein Do Muscle Mass Watchers Need?

For those, who want to maintain muscle mass, are not suggested protein intake amount in percentages of calories, but they are advised to take protein in grams per body weight unit. Where this amount is for per day or on daily basis, the body weight is in kilograms or pounds.

1 gram per pound of body weight
2.2 grams per kilogram or body weight

Although if we want to know the exact quantity of protein intake, research suggests contradictory amounts:

More than 0.8 gram per pound doesn’t help.
Slightly greater than 1 gram per pound gives best results.

Yet most support quantity is as below:

0.7 to 1 gram per pound of body weight
1.5 to 2.2 grams per kilogram of body weight

Protein Diet and Muscle Soreness

If you are suffering from muscle soreness after a heavy workout or weight-lifting schedule, don't forget to introduce adequate protein to your diet as protein helps in repairing and replacing the body tissues. It saves you from experiencing a prolong recovery process. But remember! Over-eating of protein will not speed up the healing process, so it is in vain to consume too much protein to get better results soon. Our body needs its time to heal, which can't be done at fast pace. So be patient!

Protein Supplements: Vegetarians Vs Non-Vegetarians

Protein Need Per Day

In case of protein, the recommended dietary allowance differs age-to-age and as per level of daily physical activities. However, 2 to 3 servings of protein sources in the diet is beneficial for healthy tissues.

Considering the above fact, either we can rely on animal proteins or can go with combining more than one type of plant proteins in our diet.

Protein Sources for Vegetarians: Protein Rich Food and Fruits

Here, one thing needs to be clear that animal protein doesn't mean lean meat or eggs only. Vegetarian people can get it with milk or milk products too.

Let's know some combinations for veggies, which can fulfill the body requirement of protein!

Protein Source: Whole grains
Combining food: Legumes

Protein Source: Rice
Combining food: Beans

Protein Source: Toasts of whole wheat
Combining food: Peanut butter

These all are high-quality protein rich sources that supply plant-based proteins.

Idea of Protein Quantity

For giving you an idea about how much protein a serving contains, below are some measurements!

Protein Source: Milk
Quantity: One cup
Amount of protein: 8 grams

Protein Source: Dry Beans
Quantity: One cup
Amount of protein: 16 grams

Protein Source: Meat
Quantity: 3 ounce portion
Amount of protein: 20 grams

Important to Know: Basic Terminology of Protein Requirement Amount

For indicating the amount, ‘grams of protein’ or ‘’pounds of protein’ are two terms that are used commonly. Here it means ‘grams of macronutrient protein’ and not ‘grams of food like vegetable, soya or eggs’. So do not confuse with this.

For example: An egg weighing 46 grams contains only 6 grams protein. So by taking 46 grams of egg, you are not going to take 46 grams of protein, but just 6 grams of protein.

So here you will know how much 'real protein' amount, not food amount. This kind of terminology is used because different food, fruits and vegetables consist different amount of nutrients. One can't say "take 1 apple" for some results because that apple can be smaller or bigger which changes its nutrition value.
