Scientific Researches Proving Weight Loss from Atkins Diet
PUBLISHED STUDIES SUPPORTING ATKINS
Author Accurso Year Title 2008 Dietary Carbohydrate Restriction in Type 2 Diabetes Mellitus and Metabolic Syndrome: Time For a Critical Appraisal Journal Nutrition & Metabolism University/Funding n/a This is a review article. Summary Experiments are summarized showing that carbohydraterestricted diets are at least as effective for weight loss as low-fat diets and that substitution of fat for carbohydrate is generally beneficial for risk of cardiovascular disease. These beneficial effects of carbohydrate restriction do not require weight loss. Finally, the point is reiterated that carbohydrate restriction improves all of the features of metabolic syndrome.

2010 Modified Atkins Diet Brought Back The Duodecim Joy of Life to a Developmentally Severely Disabled Youth

Paijat-Hame Central Hospital, Authors describe a developmentally severely disabled man, Neurology and Internal Medicine whose epilepsy settled, autistic features were alleviated, Clinics/Funding not listed. behavioral problems disappeared and whose weight and blood lipid and glucose values have remained normal for one year during a modified Atkins diet. Agatston Research Institute/Agaston Research Institute Compared with the NCEP diet, the MLC diet, which is lower in total carbohydrates but higher in complex carbohydrates, protein, and monounsaturated fat, caused significantly greater weight loss over 12 weeks. Weight loss was significantly greater in the Modified Low Carbohydrate (13.6 lb) than in the National Cholesterol Education Program group (7.5 lb), a difference of 6.1 lb. There were significantly favorable changes in all lipid levels within the MLC but not within the NCEP group. Waist-to-hip ratio was significantly decreased within the MLC group.

Mean seizure frequency after the first, second and third months of treatment were significantly lower than at baseline. The Atkins diet can be considered as a safe and effective alternative therapy for intractable childhood epilepsy. Atkins diet was well tolerated in our patients with rare complications and it appears to demonstrate preliminary efficacy in childhood refractory epilepsy.

2004 Clinical Experience of a Carbohydrate- Metabolic Duke University Medical Restricted Diet for the Metabolic Syndrome and Center/Atkins Foundation Syndrome Related Disorders

In this outpatient program, a carbohydrate-restricted diet and a low-fat/low-calorie plus medication led to weigh loss, but the carbohydrate-restricted diet had a more favorable effect on triglycerides and HDL. Because of the side effects on weight, triglycerides, and HDL, a carbohydrate-restricted diet may be useful for the treatment of metabolic syndrome. Low carbohydrate diets lead to a marked improvement in glucose homeostasis in association with a reduction in antidiabetic therapy and weight loss. These findings show that a 12-week low-carbohydrate diet improves postprandial vascular function more than a LFD in individuals with atherogenic dyslipidemia.

In addition to these markers for MetS, the CRD subjects showed more favorable responses to alternative indicators of cardiovascular risk: postprandial lipemia (-47%), the Apo B/Apo A-1 ratio (-16%), and LDL particle distribution. The results support the use of dietary carbohydrate restriction as an effective approach to improve features of MetS and cardiovascular risk.

2004 Comparison of a Very LowCarbohydrate and Low-Fat Diet on Fasting Lipids, LDL Subclasses, Insulin Resistance, and Postprandial Lipemic Responses in Overweight Women

J Am Coll Nutr

University of Connecticut/Atkins Compared to a low-fat weight loss diet, a short-term very lowFoundation carbohydrate diet did not lower LDL-C but did prevent the decline in HDL-C and resulted in improved insulin sensitivity in overweight and obese, but otherwise healthy women. Small decreases in body mass improved postprandial lipemia, and therefore cardiovascular risk, independent of diet composition. This study shows a clear benefit of a VLCK over LF diet for shortterm body weight and fat loss, especially in men. A preferential loss of fat in the trunk region with a VLCK diet is novel and potentially clinically significant but requires further validation.

    Once assigned, the women read a book about their respective diet, then attended a weekly class for eight weeks, after which they were on their own. The study is reported as correlational research; women form each diet group were measured for the following variables: weight loss, HDL (high density lipoprotein) cholesterol, and blood pressure. At the end of one year, the Atkins group lost an average of 10 pounds; the Zone dieters 3.5 pounds; the Ornish dieters almost 5 pounds, and the LEARN diet almost 6 pounds (Tanner, 2007). The Time.com article reports that "the Atkins women had slightly higher HDL cholesterol, the good kind, and slightly lower blood pressure than the other three diets" (Tanner, 2007,…

    “Calorie restriction” is the diminished intake of energy on a daily basis. Several laboratory experiments tested different animal species, discovering that reducing the intake of calories can decrease bodily fats and increase the life span of these species, therefore it has been also called “The Longevity diet” (Delaney and Walford, 2010). Diet is “the kinds of food that a person, animal, or community habitually eats or a special course of food to which a person restricts themselves, either to lose weight or for medical reasons” (Oxford Dictionaries, 2012). Several scientists in different experiments on animals also showed that “calorie restriction” could beneficially and non-beneficially affect other aspects of the animals health. “The Longevity Diet” is a diet that applies the “calorie restriction” method, claiming to be able to affect the anti-aging process in humans (Delaney and Walford, 2010). Experiments on humans started not many years ago, in order to understand if it is possible to recreate the same effects found in animals. Whether or not the process of ageing can be affected by low calorie restriction in humans is not yet known, due to a longer life span of humans, but it is known that to be slim decreases the the risk factors of developing “diseases such as cancer, heart disease, and diabetes” (Zamora, 2012). Several scientists, health organizations and complementary therapists are concerned as to whether a calorie restriction diet on humans could be beneficial, arguing quality of life, and possible physiological reactions of…

He was a resident at a north Liverpool care facility. He was initially diagnosed with the early stages of dementia in March 2010. Although his care plan did show that this person, who we shall call R for the duration of this case study, was sometimes resistant to being supported, he did however have a large appetite. His appetite did not correspond directly to his height and weight, at just 5 foot 3 he weighed 9 stone 2 pounds. His normal everyday breakfast would start off with a Banana, followed by a 2 shredded wheat with sugar and milk, followed by a slice of toast with Jam, followed by a juice containing a fibergel and then a coffee with full fat milk and sugar.

    Obesity is an illness of the mind and the body. In the United States it continues on a startling rise. This problem is especially detrimental to the Native American population. Studies indicate that obesity rates among the Native American population is "higher than the respective U.S. rates for all races combined" (Broussard 536S). As obesity among this population continues to rise, the number of Native Americans suffering from obesity related diseases will rise as well and the projected life span of this population will continue to decline.…
