The low-carbohydrate diet and the low-fat diet take two different approaches to achieve the same goal of weight loss. The fundamental difference between the two diets is found in the comparison of their nutritional recommendations. Nutritional recommendations are the foundation of both diets, although their views on the role carbohydrates, proteins, and fats should play differs greatly. Dieters are told that following these nutritional recommendations will promote weight loss. The amount of weight loss achieved with either diet fluctuates over time and in the end, the results for the two diets are similar.
Low-carbohydrate diets recommend eating foods high in fat and protein while limiting carbohydrates in order to promote weight loss. Foods high in fat and protein are the main source of calories during the first phase of weight loss on the Atkins diet. It is recommended that fat make up about 60% of calories ingested and protein make up 35% of calories ingested. The Atkins diet does not restrict calorie intake and they recommend that you eat until you are full. Researchers believe that overeating is avoided due to the lasting satiety dieters receive from eating large amounts of protein. The Atkins diet allows 5% of calories to be from carbohydrates, ideally only from non-starchy vegetables. The logic behind the restriction of carbohydrates is that without them present in the blood, the body is more likely to utilize stored fat for energy. Unlike many other diets, restrictions are not placed on the kind of fat and protein to be consumed; dieters are able to choose for themselves whether to stick with lean meats and unsaturated fats or to choose fatty...

...le to shed pounds more quickly than those dieters eating lots of carbohydrates on the low-fat diet.
Low-carbohydrate and low-fat diets require adherence to very different nutritional recommendations while ultimately achieving similar weight loss results. Low-carbohydrate diets, such as Atkins, encourage dieters to eat things high in protein and fat, whereas the low-fat diet requires dieters to eat mostly carbohydrates while limiting protein and fat intake. Researchers have found that both of these diets help to promote weight loss short term using strict nutritional recommendations, but that neither of them seem to be able to help dieters maintain their lower weight long term.

- Comparing and Contrasting the Atkins and South Beach Diets The weight loss industry is a multi-billion dollar machine, perpetually fueled by not only new information, but also data that have remained true for decades. Although it is unsurprising that the human body will lose weight when it expends more calories than it consumes, new findings lead to several alternative diets and weight loss methods that gain much more popularity than the basic concept of eating less and exercising more. For several decades, the Mayo Clinic diet, which was never actually invented or been approved by the true Mayo Clinic, has been used by dieters as a way to quickly lose body fat....

- Comparing and Contrasting the Atkins and South Beach Diets The Atkins and South Beach diets appear to be the same, but they do have their differences. They both suggest that limiting carbohydrates in ones. meals is a successful way to lose weight. Each diet also consists of a series of phases where carb intake can gradually increase. Although these correlations between the two diets make them difficult to be distinguished, they are in fact quite dissimilar. Whereas the Atkins diet allows consumption of all fats and hardly any carbs, the South Beach diet permits certain carbs and does not allow just any fat product....

- (2)Weakness The evidence was found from other papers,and there are some methodology drawbacks.When compared the low fat and low carbohydrate diet,researcher collect data from 17 trails without specific patient-level data.The other research based on the CHD rate only had 148 men and women participants and only 119 of them finished the trail,so that the sample size is not representative to draw a conclusion.Moreover,the result is lack of heart disease end point.The trail for women was lack of long-term intervention data.It just focus on women aged 50-79,the data can not represent all age groups.When focus on saturated fat，the trail collect the data from 6 RCT,but only one of them had healt...

- Comparing Low-Carbohydrate Diets and Low-Fat Diets The two diets I will be focusing on are comparing the low-carbohydrate diet or the Atkins diet to low-fat diets. The low-carbohydrate diet on one hand restricts the amount of carbohydrate a person consumes, resulting in greater weight loss after six months compared to low-fat diets. The low-fat diet, on the other hand, allows people to lose weight by restring the amount of fat they consume on a daily basis thus causing the person to lose weight as well, but not as much as they would have had they been on a low-carbohydrate diet for the pass six months....

- Comparing Low Calorie, Low Fat, and Low Carbohydrate Diets Comparing low calorie diets, low fat diets, and low carbohydrate diets involves looking at how they work, what problems they have, and what foods are allowed, restricted, or prohibited on each diet. Therefore, it is essential to keep in mind the recommended daily allowances of each nutritional component of a diet at non-weight loss conditions. The major nutritional components of a diet are grouped into the major categories fat, carbohydrates and sugars, and proteins.... [tags: Health Nutrition Diet Exercise Essays]

- Comparing Low-fat, Low-calorie, and Low-carbohydrate Diets Low-fat, low-calorie, and low-carbohydrate diets are of unequal effectiveness and merit. Low-carbohydrate diets are simply better. All three diets attempt to induce weight loss by managing the body’s energy intake. The body gets the energy it needs to stay alive from food. Food can be broken down into three major categories: carbohydrates, protein, and fat. Even though fat contains the most calories per gram, because of the way digestion works, the body gets all of its energy from carbohydrates and none from fat found in food....

Little University of Phoenix Comparing and Contrasting Research Paradigms Paradigms are belief systems that establish our actions patterns, practices and thoughts. Webster Dictionary defines paradigm as "an example or pattern: small, self-contained, simplified examples that we use to illustrate procedures, processes, and theoretical points." The most quoted definition of paradigm is Thomas Kuhn 's (1962, 1970) concept in The Nature of Science Revolution, paradigm as the underlying assumptions and intellectual structure upon which research and development in a field of inquiry is based....

- The anti-fat attitudes and the 'low-fat era ' that has been circling our societies for the last few decades has influenced us into believing that fat is the biggest enemy and causer of health-related diseases. Instead of further research, American 's instantly jumped on the anti-fat bandwagon and began cutting out saturated fats at the end of the 20th century. The problem with this was that with food now being low in saturated fats, food such as typical family roasts now no longer consisted of a leg of lamb on a Sunday night....

- Compare and Contrast Low Carbohydrate Diets and Low Fat Diets The two most popular methods to lose weight are the low carbohydrate diets and the low fat diets. Both are in complete contrast when it comes to each diet’s food choices, the low carbohydrate diet which completely breaks the food pyramid limits a person to eating foods that are high in carbohydrates, such as bread, pasta and rice, while on the other hand, the low fat diet which follow the food pyramid limits a person to eat foods that are high in fat like meat, milk, and bean groups....

- The purpose of this essay is to compare Low carb and Low Fat diets and examine their similarities and differences. Two studies in the New England Journal of Medicine provide evidence that in the short term, a low-carbohydrate diet helped people lose weight without any adverse effects. In the last decade, several leading nutritional scientists have taken the side effects into consideration. They have begun to think that the low carb diet may be partly right about losing weight, and scientists are now finally studying whether low-fat diets really work....
