It seems like you're asking about the terms related to weight loss and dieting. Here's a brief explanation of each:

1. Body Composition: This refers to the proportion of fat and fat-free mass (muscle, bone and water) in your body. A healthy body composition is one that includes a lower percentage of body fat and a higher percentage of fat-free mass.

2. Body Mass Index (BMI): This is a measure that uses your height and weight to work out if your weight is healthy. The BMI calculation divides an adult's weight in kilograms by their height in meters squared.

3. Diuretics: These are substances that help to get rid of salt and water from your body. They are often used to treat high blood pressure; however, they are not suitable for losing weight.

4. Fad Diets: These are stylish weight-loss plans that promise significant weight loss in short periods of time. They often suggest cutting out food groups or buying premade meals. However, they are not usually sustainable or healthy in the long term.

5. Metabolism: This is the process by which your body converts what you eat and drink into energy. During this complex process, calories in food and beverages are combined with oxygen to release the energy your body needs to function. Some people have a faster metabolism than others, and this can affect weight loss.
