The term diet is derived from the word dieter which means one who eats. In nutrition, diet refers to the quantity of food ingested by an organism or individual. Some people believe that eating to lose weight requires strict monitoring and regimentation while others believe that diet should be flexible in nature and allow certain foods to be eaten in moderation. In recent years there has been an increased intake of junk food and other foods that are not good for you. Due to this increase in intake, there has been a corresponding increase in the occurrence of obesity and overweight in the world today. A good diet should consist of all the essential nutrients while avoiding saturated fat and other harmful fats found in canned and processed foods.
Many people believe that a strict diet should only be followed by people with severe illnesses such as cancer or HIV/AIDS. However, it is important to note that a healthy and balanced diet can help prevent obesity and weight gain in anyone at any time. There are many food groups that can help dieters to lose weight. These food groups are carbohydrates, proteins, fruits, vegetables, dairy products, oils, and alcohol.
A diet that consists mainly of carbohydrates such as pasta, rice, breads, cereals, potatoes, etc. is known as a carbohydrate-rich diet, while a diet that consists mainly of proteins, fats, fruits, vegetables, and dairy products is known as a protein-rich diet. A diet that consists of mainly processed foods such as junk food, fast food, prepackaged foods, etc. is considered to be an unhealthy diet.
