Medium term effects of a ketogenic diet and a Mediterranean diet on resting energy expenditure and respiratory ratio

2012

Background Very low carbohydrate ketogenic type diets (VLCKD) have been shown to be more effective for body weight reduction and fat loss compared to balanced or low-calorie Mediterranean diets, at least in the short-medium term [1,2], although the underlying mechanisms of its efficacy are still not well understood. Despite being a diet in widespread use there are few data available regarding effects on respiratory ratio (RR) [3,4] and resting energy expenditure (REE) and, more specifically, there are no reports about the effects on RR following a return to a non ketogenic diet. The aim of this study was to compare the effects of a 20 day ketogenic Mediterranean diet with phytoextracts (KEM…

Effects of a ketogenic diet in overweight women with polycystic ovary syndrome.

2019

Abstract Background Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women during reproductive age. It is characterised clinically by oligo-ovulation or anovulation, hyper-androgenism, and the presence of polycystic ovaries. It is associated with an increased prevalence of metabolic syndrome, cardiovascular disease and type 2 diabetes. The onset of PCOS has been associated to several hereditary and environmental factors, but insulin resistance plays a key pathogenetic role. We sought to investigate the effects of a ketogenic diet (KD) on women of childbearing age with a diagnosis of PCOS. Methods Fourteen overweight women with diagnosis of PCOS underwent to a ketoge…

The Effect of a Ketogenic Low-Carbohydrate, High-Fat Diet on Aerobic Capacity and Exercise Performance in Endurance Athletes: A Systematic Review and…

2021

A low-carbohydrate, high-fat (LCHF) diet has been proposed to enhance the fat utilization of muscle and the aerobic capacity of endurance athletes, thereby improving their exercise performance. However, it remains uncertain how the macronutrient intake shift from carbohydrate to fat affects endurance exercise training and performance. This study performed a systematic review and meta-analysis to explore the effects of a ketogenic low-carbohydrate, high-fat (K-LCHF) diet on aerobic capacity and exercise performance among endurance athletes. Searches were carried out in five electronic databases, and we followed the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) gu…

Ketogenic diet and microbiota: Friends or enemies?

2019

Over the last years, a growing body of evidence suggests that gut microbial communities play a fundamental role in many aspects of human health and diseases. The gut microbiota is a very dynamic entity influenced by environment and nutritional behaviors. Considering the influence of such a microbial community on human health and its multiple mechanisms of action as the production of bioactive compounds, pathogens protection, energy homeostasis, nutrients metabolism and regulation of immunity, establishing the influences of different nutritional approach is of pivotal importance. The very low carbohydrate ketogenic diet is a very popular dietary approach used for different aims: from weight …

The Role of Nutritional Lifestyle and Physical Activity in Multiple Sclerosis Pathogenesis and Management: A Narrative Review

2021

Studies on the role of nutritional factors and physical activity (PA) in the pathogenesis of multiple sclerosis (MS) go back a long time. Despite the intrinsic difficulty of studying their positive or negative role in MS, the interest of researchers on these topics increased during the last few decades, since the role of diet has been investigated with the perspective of the association with disease-modifying drugs (DMD). The association of DMD, diets, and PA might have an additive effect in modifying disease severity. Among the various diets investigated (low-carbohydrate, gluten-free, Mediterranean, low-fat, fasting-mimicking, and Western diets) only low-carbohydrate, Mediterranean, and f…

Effects of carbohydrate content on body composition during weight loss in female fitness competitors

2017

Introduction. Bodybuilders and fitness competitors are aiming to reduce fat mass and maintain lean mass during the competition phase. Low carbohydrate diets compared to low fat diets have claimed to be more effective in weight loss, but the results are still controversial. Low carbohydrate intake and high protein intake have been reported in bodybuilders during the diet, but the evidence of its effectiveness is limited. The aim of this study was to examine the effects of carbohydrate content on body composition during weight loss in female fitness competitors. Methods. A total of 50 female subjects participated in this study, 27 were competitors, and 23 were weight training stable controls.…

Short and middle term effects of hypocaloric low carbohydrate diet vs hypocaloric Mediterranean diet on endothelial function in obese subjects

2008

Adequate nutritional treatment is required to address the problem of increasing prevalence of obesity in Western countries. The Mediterranean diet style is now acknowledged to have large scientific evidences in terms of cardiovascular prevention. However, many popular diets are diffusing also as self-prescribed treatments. Among those, the efficacy of low-carbohydrate diets (also known as Atkins’ diet in its most popular variety) has been addressed by some investigations. It is generally concluded that the low-carbohydrate diet is able to induce a greater weight loss, at least in the middle term, and a better serum lipid profile than the conventional diet. In this longitudinal, randomised, …

Ketogenic diet does not affect strength performance in elite artistic gymnasts

2012

Abstract Background Despite the increasing use of very low carbohydrate ketogenic diets (VLCKD) in weight control and management of the metabolic syndrome there is a paucity of research about effects of VLCKD on sport performance. Ketogenic diets may be useful in sports that include weight class divisions and the aim of our study was to investigate the influence of VLCKD on explosive strength performance. Methods 8 athletes, elite artistic gymnasts (age 20.9 ± 5.5 yrs) were recruited. We analyzed body composition and various performance aspects (hanging straight leg raise, ground push up, parallel bar dips, pull up, squat jump, countermovement jump, 30 sec continuous jumps) before and after…
