Every living thing needs a means of sustaining its life, organisms achieve this feat by a periodic supply of nutrients into their body system. Without the constant supply of this sustenance, the life of this organism will be threatened, even at low supply, the normal workings of an organism’s bodily functions will be disrupted. Different organisms derive nutrients through various means, some of which are more complex than the other. Simple living things like most single-celled organisms derive sustenance by absorbing it directly into their body from their immediate environment. The processes they used to achieve this are usually simple biological phenomena like osmosis/diffusion.
Multicellular organisms like human beings have a more sophisticated way of deriving nutrients. This is done mainly by a process called feeding. Feeding involves a way by which an organism ingests large substances that are usually rich in several nutrients into their system. The ingested food is passed through their alimentary canal where digestion of the food occurs. Digestion is also another biological process that involves the internal breakdown of food items into smaller entities that can be absorbed by the cells of an organism. The product of digestion is molecules or compounds that perform different functions in your body. This particular function performed by the digested food is used for classifying the food into different groups.
Food items can be categorized into different groups based on the functions they perform in the body after digestion. These groups include; carbohydrates, proteins, lipids, vitamins, roughages, minerals, and water. Carbohydrates are the most preferred source of energy food of the body, they include foods that contain high concentrations of sugar/starch. Proteins are referred to as the building blocks of your body, this is because your body is made mainly from proteins, from your muscles to the skin, almost all of your internal structure is made from this macromolecule. Due to its function, proteins are highly priced in meals and several diets, especially for active growing people.
Lipids are utilized as an alternative source of energy for your body and are utilized when carbs are in short supply/absent in diets. They are also an important component of the fatty layer below the skin which serves as insulation for you during extreme weather conditions. Minerals and vitamins are similar in function, they are not needed in much quantity like the other food groups, but are as important. Both help maintains the healthy state of your body and contributes to most of the activities carried out in your body system. Water exists as an all-important life-supporting liquid, that is vital for many biological processes in your body. It is so important that you can’t survive four days without taking in the molecule into your system.
Roughages are the only substance considered as nutrients that can’t be digested by your body. However, they help in maintaining the digestive health of your body. With the multiple types of food that exists, there has to be a planned process to make sure all these classes of food are introduced into your body in the right proportion. A diet that meets all these requirements is called a balanced diet. Other diets exist apart from a balanced diet that was created to meet a particular goal by the consumer, one of which is what we know as the Ketogenic diet/Keto diet.
Keto diet is a diet that is high in fats, moderate in protein, and very low in carbohydrates. It is done to switch your body from depending on carbohydrates as its main source of energy to depending on an alternative means, fats. This diet is peculiarly created for people that wish to lose weight since this diet forces your body to burn your stored fats as its main source of energy. Ketogenic diets have other health benefits apart from serving as fat removal, it similarly helps patients with cancer, epilepsy, diabetes, and Alzheimer’s disease in combating their medical condition. Keto diets initiate a metabolic process called ketosis in your body, which exists as an alternative to glycolysis.
Since there is low or no glucose in circulation, the body turns to ketone bodies as the new source of energy. Ketones are created by the emulsification of stored fat by the liver, and these ketones produced are used in producing ATP. Keto diet has many health benefits but can be disastrous to the system. It could lead to liver failure since you are giving your liver more work than normal. You may yet experience poor energy and mental function because you are not supplying your body with its preferred energy sources. To avoid these complications you should seek professional advice, before embarking on a keto diet.
