Lose and Maintain Weight? Meat, fish, poultry, eggs, cheese, low-CHO vegetables, butter, oil; no alcohol. Carbohydrates, specifically bread, pasta, milk, most fruits and vegetables Limited food choices. Yes, but initial weight loss is mostly water.
In this edition, we will examine the scientific pros and cons regarding low carbohydrate, high protein diets such as the Atkins and South Beach diets in managing our weight and achieving optimal body composition. We will then discuss a few tips for safe and permanent weight management.
Energy intake comes from intake of carbohydrates four calories per gramprotein four calories per gram and fat nine calories per gramand of course, alcohol seven calories per gram. Energy expenditure includes Resting Energy Expenditure REEwhich is the amount of energy required for the body to function in a state of rest.
REE depends on Fad diet research paper size of body, amount of lean or fat mass, age, gender, thyroid gland activity, body temperature, health and disease status and environmental temperature.
Mahan and Escott-Stump estimate the REE accounts for up to 60 to 70 percent of the total energy expenditure per day.
The other major energy expenditure is the amount of energy required for physical activities. The amount of energy required for physical activity also relates to body size, age, and lean or fat mass. To achieve and maintain optimal body weight, it is essential to balance these two types of energy requirements.
If one takes in more energy than one expends, the extra energy will be stored as fat, which leads to Fad diet research paper increase in the BMI and percentage of body fat. On the other hand, if one consumes less energy than one expends, then the body will utilize the fat stored, thus reducing BMI and percentage of body fat.
This is a fact that has been confirmed over and over again. Just looking at societies whose members have to engage in daily physical activities, such as walking to the bus stop or underground station, or third world countries whose members do not have the luxury of taking in a large amount of food per day and have to endure some daily physical activities, shows that obesity is not a problem at all.
So, if it is that easy to balance food intake with physical activity, then why do people have such a hard time losing weight and keeping it off? Another factor contributing to the difficulty in balancing energy intake with energy expenditure is that the composition of the food is now higher in refined and simple carbohydrates which results in quick absorption, thus causing hunger urges which, in turn, lead to more consumption.
Due to these reasons, some people have a difficult time balancing their energy intake with their energy expenditure and they become obese.
The trend of increasing obesity has continued in the United States over the last few decades in spite of known detrimental consequences, such as development of hypertension, high serum cholesterol, cardiovascular disease, type II diabetes, and many others.
A number of ways have been suggested to treat obesity, including surgery, medication, and of course, numerous types of diets and weight management programs. Low carbohydrate, high protein diets have gained a lot of attention in recent years. Do these diets work—and are they safe?
Low Carbohydrate, High Protein Diets The Atkins diet, which restricts carbohydrate intake and prescribes high protein intake in order to lose weight, was developed by Robert Atkins about 20 years ago. He was a cardiologist who believed that a high protein diet would facilitate weight loss and improve serum cholesterol and thus reduce the incidence of heart disease and other complications associated with excess body weight.
Atkins believed that his diet works because it limits production and excretion of insulin, an anabolic hormone, which does not promote fat oxidation when elevated, whereas the lack of insulin leads to mobilization of body fat for production of energy, as evidenced by the increased production of ketone bodies.
He argued that the increased production of ketone bodies also reduces appetite, which allows for better weight maintenance. Although he never conducted a scientific study to prove that his diet works and is safe, he used his patient cases in his bestselling book, Dr.
So, does the diet work as claimed?
In this study, the authors examined studies published from through that dealt with low carbohydrate grams per day and high carbohydrate greater than 60 grams per day caloric restricted diets.
The majority of the studies had a randomized research design with a control group. The dietary variables included the grams of carbohydrate, fat and protein and total calories that were given to participants per day.
Another variable was the duration of dietary intervention or the number of days days which the participants received the intervention. The participants were divided in two groups, with one group receiving a low carbohydrate, high protein diet and the other group receiving a caloric restricted, high carbohydrate diet.
The conclusion of this study indicated that the higher weight loss was achieved by the participants who had a lower caloric intake and were on the diet for a longer period of time, but there was no correlation with reduced amounts of carbohydrate intake. Furthermore, the authors found that low-carbohydrate diets did not have any adverse effects on fasting serum lipids, glycemic index or blood pressure.
The authors then concluded that they could not draw any conclusions for or against low carbohydrate diets. Body composition, blood pressure, and fasting blood glucose were measured at baseline, at three months, and at the end of the study at six months.
Each subject was also given an electrocardiogram during each of these three test intervals. The results clearly indicated that the subjects on the low carbohydrate diet lost more weight 8.A fad diet is a diet that becomes popular quickly, and may die out just as quickly.
