Dietary Effects on Weight Loss and Lipid Profile in Sedentary Women
A study testing NCD and LCD in people with Obesity and Overweight, run by P.L.Shupik National Medical Academy of Post-Graduate Education.
Trial summary
Negative-calorie diet is among the popular dieting guides for weight loss; however, there is still little knowledge about this method. The present study aimed to determine the effects of negative-calorie diet on weight loss and lipid profile, and to compare its efficiency with low-calorie diet. Read more about this study
