A good fiend of mine asked me a while ago what is the difference between a diet and nutrition. Diet is a part of the nutrition. Here’s the explanation:
Nutrition is the science that studies the process by which living organisms acquire all the things that are necessary for them to live and grow. Nutrition focuses on the role of nutrients, which are defined as substances that the body cannot make on its own and include things like vitamins, minerals, and certain macromolecules. Basically, nutrition consists of diet (what you take in) and metabolism (what happens to it after it enters your body).
Diet is what you eat. There are two aspects to your diet: what foods you eat and how much of them you eat. To lose weight or maintain a healthy weight, you need to pay attention to both factors. If you eat all the right foods but they are in quantities that are too large, you will take in too many calories and will gain weight. If you eat the right amount of calories but you get them from only one food group, you will lack essential nutrients which may cause serious health problems.
