In nutrition, diet plays the role of regulating the intake of macronutrients (food substances). These are nutrients needed to maintain healthy physiology and body functions and sometimes even to promote the growth of necessary cells. Normally, one can see that most people follow diet plans in order to lose weight, maintain their body weight, and even to prevent diseases like obesity and diabetes. There are three main types of diet plans: low fat, low carbohydrate and low protein. It is also important to note that diet can be combined with other practices such as exercise and proper lifestyle.
In nutrition, the diet means the amount of foods consumed by an individual or group. The first entry in the definition of diet is a dietary plan, which is defined as the arrangement of foods that an individual adopts for his or her food needs. The objective of an individual diet is to meet the nutritional requirements. The term diet has many variants e.g. fat-free diet, low-fat diet, low-carb diet, vegetarian diet, etc.
Diets allow people to control their intake of calories and other nutrients. The amount of food intake is set either by quantity or frequency of eating habits. Some diets include foods from different sections of the food pyramid. Some people may follow a diet plan that is based on the caloric content of the foods.
Foods are categorized according to their nutrients and calories based on the amount of carbohydrates, protein, fats, and other essential nutrients. Nutrient content refers to the number of calories per serving and not the total calories consumed. It is important to choose balanced diet plans for the health of an individual. A balanced diet plan ensures the proper functioning of the different systems of the body. Therefore, it helps in avoiding obesity and many related chronic diseases. It is necessary to choose a nutritious diet rather than a balanced diet that contains high levels of calories and fat that can cause serious harm to the health.

But the truth is that there are many other foods that can be consumed in the diet and they do not all require to be drunk only. Some foods that are good to eat and are beneficial to the body include beans, nuts, seeds, sea vegetables, asparagus, spinach, lettuce, carrots, celery, green and red peppers, radishes, and cucumber. These foods are considered as non-starchy vegetables and therefore can be included in the diet without much effort. It is also important to choose a healthy drink in order to have a balanced diet plan.
Drinks like water, orange juice, soy milk, and low-sugar, non-fizzy drinks can be selected and added to the daily diet regimen. Water and fruit juices are recommended as they help in flushing out the toxins from the body while small amounts of vegetables and grains can be taken in small quantities. In order to achieve weight loss and to have a healthy diet plan, it is very essential to follow a proper and well-maintained regimen.
