Should Low-Carbohydrate Diet Be Avoided? Obesity or overweight can be a risk factor for diabetes or hypertension (high blood pressure), which would ultimately lead to heart disease. And it is extremely difficult for one to reduce weight once he or she becomes obese or overweight. In order to prevent from becoming obese or overweight, one should adhere to healthy diet and have regular exercises. Taking low-carbohydrate (low-carb, in short) diet is just one of the many types of diet some health experts would recommend to people who wish to stay slim. A good example of low-carb diet is the famous Atkins diet. While dieters on low-carb diet might achieve the goal of maintaining their body shapes, they might suffer from halitosis, or more commonly known as bad breath. Why is this so? First of all, one should be aware that low-carb diets restrict the daily intake of carbohydrates like grain-based foods. Carbohydrate is our body’s main source of energy. When it is unavailable or insufficient, the body will naturally switch to burning body fat and protein for energy. Such process will cause some chemicals, known as ketone, to be produced through the urine and lungs. The smell coming from the breath of a person on a low-carb diet tends to be like acetone, similar to the smell coming from nail polish removers and paint thinner. This is different from the sulphurous smell caused by oral hygiene problems, such as bacteria in the throat or at the back of the tongue.
Besides bad breath, there are of course other short-term effects of a low-carb diet, including fatigue, poor concentration and dizziness. When there is inadequate carbohydrate available for consumption, the body will have insufficient energy to run. Hence, feeling tired and dizzy is not uncommon for low-carb dieters. It is rather difficult to get rid of the bad breath generated from low-carb diet as a result of a metabolic imbalance. One way to minimize the problem is to drink enough water or suck on mints. But these measures only can mask the bad breath. Nevertheless, once one decides to stay away from low-carb diet, this type of bad breath could just be eliminated almost immediately provided he or she has no other underlying dental problems. According to dietitians’ explanation, dieters adopting low-carb diets might have rapid weight loss initially because of water loss. Instead, they advise dieters to stick to a diet that is low in calories and high in dietary fiber from vegetable, fruit and wholegrain foods. For those who want to lose weight, consuming dietary fiber would definitely help as it makes them feel full. The recommended carbohydrate intake should make up between 50 and 55 percent of one’s total calorie intake while the proportion of protein and total fat intake should be between 15 and 20 percent, and between 25 and 30 percent respectively. Dietitians favoring low calorie diets believe losing weight is about cutting down the total calories. When a person consumes high amount of fat, he or she should focus on reducing on the fat first. This is because 1 gram of fat contains 9 calories, which is more than double the amount of calories of 1 gram of carbohydrate produces, only 4 calories.
