REFLECT AND APPLY A friend who is trying to lose weight complains about the odd taste in his mouth in the mornings. He says it seems like a filling has broken loose, and the metallic sensation is bothersome. What would you say?

Expert Solution
Interpretation Introduction

Interpretation:

The inference that can be drawn from the odd taste of the mouth in the morning, of a friend who is trying to lose weight and also complains about the metallic sensation, is to be discussed. It seems that a filling has broken loose in his case.

Concept introduction:

A weight loss diet involves low carbohydrates. The carbohydrates are stored as glycogen in the body and are the chief source of energy. The fats are another source of energy and their breakdown involves the production of acetone.

The fats, if broken down in a large amount, produce acetone and cause ketosis, which is also a consequence of diabetes. The acetone is a ketone body that cannot be stored in the body.

Explanation of Solution

The friend is trying to lose weight, which means he is on a low-calorie diet. The low calorie corresponds to very less amount of carbohydrates. The carbohydrates are the major source of energy in the body, and if it is present in very low amount, then the body moves on to the other available sources to derive energy. The fat is the chief source of energy after carbohydrates. The breakdown process of fats called beta-oxidation occurs in the cytosol. The breakdown of fats produces acetone as the product, which is a ketone body. The ketone bodies, when present in excess, produce a pathological condition called ketosis...
