Effect of a High Saturated Fat and No-starch Diet on Serum Lipid Subfractions in Patients With Documented Atherosclerotic Cardiovascular Disease
James H. Hays, MD; Angela DiSabatino, RN, MS; Robert T. Gorman, PhD; Simi Vincent, PhD, MD; Michael E. Stillabower, MDProspective single arm: To determine whether a diet of high saturated fat and avoidance of starch (HSF-SA) results in weight loss without adverse effects on serum lipids in obese nondiabetic patients. HSF-SA diet results in weight loss after 6 weeks without adverse effects on serum lipid levels verified by nuclear magnetic resonance, and further weight loss…

Gary D. Foster, PhD; Holly R. Wyatt, MD; James O. Hill, PhD; Brian G. McGuckin, EdM; Carrie Brill, BS; B. Selma Mohammed, MD, PhD; Philippe O. Szapary, MD; Daniel J. Rader, MD; Joel S. Edman, DSc; Samuel Klein, MDRCT with 63 participants: The low-carbohydrate diet produced a greater weight loss (4%) than did the conventional diet for the first six months, but the differences were not significant at one year. The lowcarbohydrate diet was associated with a greater improvement in some risk factors for coronary heart disease.

James R. BailesJr.; Misty T. Strow; Joseph Werthammer; Richard A. McGinnis; Yoram ElitsurNon-ramdomized Prospective Controlled Study: Obese children following a high protein, low CHO diet (<30g/day) lost an average of 5.21 ± 3.44 kg and decreased their BMI by 2.42 ± 1.3 points, compared to the children in the Low Cal Diet (calorie restricted) who gained an average of 2.36 ± 2.54 kg and 1.00 point on the…

William S. Yancy Jr., MD, MHS; Maren K. Olsen, PhD; John R. Guyton, MD; Ronna P. Bakst, RD; Eric C. Westman, MD, MHSRCT with 120 participants: Compared with a low-fat diet, a low-carbohydrate diet program had better participant retention and greater weight loss. During active weight loss, serum triglyceride levels decreased more and high-density lipoprotein cholesterol level increased more with the low-carbohydrate diet than with the low-fat diet.

JS Volek; MJ Sharman; AL Gómez; DA Judelson; MR Rubin; G Watson; B Sokmen; R Silvestre; DN French; WJ KraemerRCT with 28 particpants: This study shows a clear benefit of a VLCK over LF diet for short-term 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.

Jeff S. Volek , PhD, RD, FACN; Matthew J. Sharman , MA; Ana L. Gómez , MS; Chris DiPasquale , MS; Melissa Roti , PhD; Amy Pumerantz , BS; William J. Kraemer , PhDRamdomized crossover with 13 participants: Compared to a low-fat weight loss diet, a short-term very low-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…

Kelly A. Meckling; Caitriona O’Sullivan; Dayna SaariRCT with 31 participants: Both groups of subjects had significant weight loss over the 10 wk of diet intervention and nearly identical improvements in body weight and fat mass. Only the LC group had a significant decrease in circulating insulin concentrations. Group results indicated that the diets were equally effective in reducing systolic blood pressure by…

It significantly reduced the body weight and body mass index of the patients. Furthermore, it decreased the level of triglycerides, LDL cholesterol and blood glucose, and increased the level of HDL cholesterol. Administering a ketogenic diet for a…

Hennekens, MD, DrPHRCT with 60 participants: 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…

Kevin D. O’Brien; Bonnie J. Brehm; Randy J. Seeley; Judy Bean; Mark H. Wener; Stephen Daniels; David A. D’AlessioRCT with 41 participants: The very low-carbohydrate dieters had a significantly greater decrease in LogSAA, but their weight loss also was significantly greater. In this study, the decreases in inflammatory markers correlated significantly with weight loss. Also, change in LogSAA correlated with change in insulin resistance. Thus, in otherwise healthy, obese women, weight loss was associated…
