Over the last century, the worldwide population has increased four times. Until 1915, there were around 1.8 billion people globally. According to the most fresh estimate by the United Nation, currently, there are 7.3 billion people worldwide and while considering the current pace of growing population, the total populace may reach 9.7 billion by 2050. This growth, along with rising incomes in emerging countries (keeping in view dietary changes like eating more protein and meat) are raising the food demand globally.

Global Demand for Food

Food demand is expected to grow somewhere between 59% to 98% by the year 2050. The change in demand will shape agricultural markets in ways which have never experienced before. Globally, the farmers will need to raise their crop yields, either by enhancing the amount of agricultural land to grow crops or by increasing productivity on existing agricultural lands through fertilizer and irrigation while keeping in view innovative methods such as precision farming.

Food security has been and will continue to be a key driver of socio-political priorities worldwide, regional and at the national level. It is expected that increasing world population, sustainability anxiety and irregular growth of income may lead the current food and agricultural sector with the everlasting issues. These issues may include (1) increasing over-all food availabilities, (2) satisfying the growing diversification of consumers’ basket, and (3) matching higher quality standards such as safety, environment, welfare and ethic, (4) keeping food reasonable. Worldwide production is growing, but still, the level of enhancement as well as agricultural progress patterns varies to a great extent globally. Beyond natural constraints, these differences reflect diverging economic and structural reforms, as well as marketing strategies and, are significantly pertaining to maintaining diversified agricultural landscapes worldwide.

In the past last 50 years, global food demand approximately tripled [1]. This rapid growth caused on the one hand by the doubling of world population from about 3 to more than 6 billion people and on the other hand, increased per-capita demand due to rising living standards. In this article, we define food demand as equivalent to food supply according to FAOSTAT. It explains the daily average availability of food in households in kcal capita−1 d−1, including both food intake and non-eaten household food waste.

Noticing a basic rule of microeconomics, the German statistician Engel observed already in the middle of the 19th century a positive correlation between per capita food demand and income that levels out for high incomes, the so-called “Engel’s Law”. Stillbeside income, per capita demand impacted greatly by other factors that include climate, age and gender composition of the population, food costs, growth of the food industry, globalization and openness to international markets, the degree of urbanization, or transformation in the role of women in society.

Scenarios of future food demand considered as an important instrument to progress strategies for accomplishing the goal of global food security. Scenarios are taken into consideration when uncertainty is too high to allow for predictions. In its place, there are alternative images of the future that “enhance our understanding of how structures work, evolve and interrelate. They can be used to discover possible futures and to localize the regions where most energy is needed to combat hunger. In addition to that, they assist in distinguishing periods in which the issues can expect to continue, such that strategies can be adapted accordingly.

In current times, according to the most recent estimate by the UN, there are 7.3 billion population and can reach 9.7 billion by the year 2050. It is believed that all of this population increase will occur in developing countries. Urbanization will remain at an accelerated pace, and about 70 per cent of the world’s population will be urban (compared to 49 per cent today). Income levels will be many multiples of what they are now. In order to feed this larger, more urban and richer population, food production (net of food used for biofuels) enhanced by 70 per cent. Annual cereal production will need to rise to about 3 billion tonnes from 2.1 billion in present and annual meat production will be required to rise by over 200 million tonnes to reach 470 million tonnes.

Global Demand for Water

There are growing concerns about the effects of climate change on water resources. A number of studies have analyzed such impact at various national levels together with the food security challenges. An ever-increasing amount of evidence suggests that the constant increase in greenhouse gas emissions is badly influencing the global climate and changing the local rainfall system and temperatures. Transformation in the climate expected to result in considerable impacts on global water resources and freshwater ecosystems. The impacts and concentration of climate change will be different in every region. Effects of climate on global water storage capabilities and hydrologic functions will have considerable consequences for water management and planning as variability in natural processes upsurges.

Global Demand in the agriculture sector

The Agriculture sector in the 21st century faces multiple challenges. The experts have analyzed that it has to produce more food and fibre to feed an increasing population with a smaller rural labour force, more feedstocks for a potentially huge bioenergy market, participating to overall progress in many agriculture-dependent developing states.

Factors behind Growing Demand

Population

The increasing demand for food expected to boost considerably by 2050.  A major factor for this hype is world population growth.  Demographic projections have a high degree of certainty, so projections of future world food requirements based on population growth are quite reliable.

Rising Incomes

Besides population growth, food requirement will rise due to the increasing incomes of people in major developing countries as they move from low income into the middle class.  As incomes increase, people like to eat fewer grains and enhance their consumption of meat and high-value foods.  This transition requires higher levels of resource utilization.  It takes multiple pounds of grain to produce a pound of meat.  Therefore, the total pounds of grain utilized by each person, directly as grain and indirectly through meat, grows considerably.

Diet with high protein requires to eat more protein and fewer carbohydrates or fat to increase weight loss, advance energy, and augment athletic performance. Protein is considered as one of the essential nutrients for the health of the body. It is accountable for the variety of important functions in the body including enzymes, hormones, maintenance and cell repair. According to some nutritionists, a high protein diet can help overweight and obese females lose more fat and at the same time retaining less muscle mass. High protein diets assist in reducing the level of hunger, surge satiety, increase metabolic rate, and reserve muscle mass. Unfortunately, in case of diet, it varies sometimes from person to person as one diet plan cannot entertain each and every person. Generally, a diet with high protein recommends taking more than 20% of your entire calories from protein. It means to intake fewer calories from carbohydrates or fats to maintain the balance of calories in the body.

The History of High-Protein Diets

High-protein diets have been around for eras. People native to the Arctic region where green life such as plants and herbs are rare can survive only on marine life and rein deers. African warrior tribes used to survive on only milk and meat. Similarly, some Native Americans know to continue their lives while eating mostly buffalo with a few plants. The high-protein diets came into trend during the late 1970swith the Scarsdale diet, which proportionates the diet of 43% protein, 22.5% fat, and 34.5% carbohydrates. Current diets that highly emphasizes on high-proteins intake comprises of Atkins, South Beach, and Dukan diets.

How High-Protein Diets Work?

It is important for any healthy diet for weight loss to incorporate a balance of three macronutrients such as fat, carbohydrate, and protein. A high-protein diet comprises at least 20% of calories from protein. The amount of protein you should intake relies on some essential factors that incorporate your age, body size, activity level, and gender.

Guidelines for Proteins

There are general plans that guide the individuals to eat between 10% and 35% of total calories as protein. Active adults may need 1.2 to 1.7 grams per kilogram of body weight each day. This connects to 82 to 116 grams for a person weighing 150 pounds. Whereas the official recommendations daily allowance for a healthy adult is a minimum of 0.8 g/kg/day. It is easy to have a check on a daily protein intake with the help of calorie tracking applications. The application is used by many people on a high-protein diet to track their macronutrient intake to ensure that they are getting the correct ratio of protein to carbohydrate and fat.
To initiate the high protein diet, it is suggested to intake 30% of calories from protein, 30% of calories from fat, and 40% of calories from carbohydrates. Later after some days, an individual can either add or reduce the level of macronutrient according to o his needs.

Recommended Meal Timing

There is no recommended meal timing for a high-protein diet, however, some individuals on a high-protein plan also practice fasting with irregular intervals, which include confining the level of calories to certain days of the week and then fasting on others days. Similarly, the practice is continued for a longer period of time without eating, sometimes even 16 hours a day.

Resources and Tips

It is important not to make the high-protein diet difficult. It needs to be easy and flexible to get continued for a longer period. Here are a few tips that can help a person to initiate:

• Contain protein in each meal. Meals should be planned around a protein, where lean beef, a chicken must be the part of your dish together with the plate of vegetables.
• Eliminate processed carbs. Instead of eating refined grains, that includes white rice, pasta, and bread, it is best to include small servings of whole grains that are rich in protein, such as amaranth or quinoa. Similarlypasta can be replaced with spiralized zucchini or carrots and replaced riced cauliflower for white rice.
• Snack on protein. Try to keep high-protein snacks aside for between-meal hunger strikes. Almonds, Greek yoghurt, hummus, ricotta, and string cheese can help o person during between-meal hunger.
• Start your day with protein. Eggs are rich in proteins and help in filling the breakfast. If someone is running short of time or is not keen of eating eggs, a smoothie prepared with protein powder, such as whey, pea protein, or collagen, leafy greens, and berries can help allot in the quick and healthy breakfast.

High-Protein Pros and Cons

Excessiveness of any food has its own pros and cons on the health of a person. Similar to every weight-loss plan, a high-protein diet has its own share of advantages and disadvantages.

Pros:

The high protein diet can help a person on building strong muscles, burning more calories, help in more filling, and eventually helps a person in improving the diet.

Cons:

The excessive use of high protein diet can lead the person to suffer from nutrient deficiency. In addition to that, a high intake of protein diet can be harmful to the kidneys, heart disease.

When the meal on the table has a lean source of protein, there is less space on your plate for those foods that are unhealthy. It is therefore suggested by nutritionists to learn to eat various types of proteins that may help a person to improve the diet and physique as well. For example, if a person eats tuna, he will not only benefit himself from the protein in that fish but can also benefit the body from the healthy fat it is included in tuna.
It is also important to note here that protein helps you burn a few extra calories because your body has to put the effort to chew and digest the food. According to scientists, this phenomenon is known as the “thermic effect of food.” The number of extra calories is small so a person should avoid creating an entire weight loss program that is purely relied on this benefit.
