Author Interviews, Brigham & Women's - Harvard, JAMA, Nutrition / 22.01.2020

MedicalResearch.com Interview with: Zhilei Shan PhD Postdoctoral fellow on Nutritional Epidemiology Harvard T.H. Chan School of Public Health MedicalResearch.com: What is the background for this study? Response: Long-standing controversies have focused on the health consequences of dietary fat and carbohydrate. Previous evidence has shown that different types of carbohydrates and fats have varying effects on disease risk and health. For example, carbohydrates from refined grains and added sugars may contribute to insulin resistance and other metabolic problems while carbohydrates from whole grains and whole fruits appear to be beneficial. Likewise, replacing saturated fat with unsaturated fat was associated with lower risk of heart disease and mortality. Therefore, it is crucial to incorporate quality and types of carbohydrate and fat when investigating the associations of low-fat and low-carbohydrate diets with mortality. (more…)

MedicalResearch.com Interview with: Radhika Seimon, PhD Research Fellow at the University of Sydney Amanda Salis, PhD - Professor of Obesity Research at the University of Sydney Senior Research Fellow National Health and Medical Research Council of Australia  MedicalResearch.com: What is the background for this study? Response: Total meal replacement diets are severely energy-restricted diets that involve replacing all or almost all foods with nutritionally replete meal replacement products such as shakes, soups, or bars (i.e. total diet replacement). They are the most effective dietary treatment for obesity, resulting in greater short- and long-term weight loss compared with conventional food-based diets. However, there are concerns that total meal replacement diets may adversely affect body composition, notably lean mass and bone mineral density. (more…)

Dr Aseem Malhotra MBChB, MRCP Honorary Consultant Cardiologist - Frimley Park Hospital Consultant Clinical Associate to the Academy of Medical Royal Colleges Science Director- Action on Sugar Saving Londoners Lives - External Advisory Board MemberMedicalResearch.com Interview with: Dr Aseem Malhotra MBChB, MRCP Honorary Consultant Cardiologist - Frimley Park Hospital Consultant Clinical Associate to the Academy of Medical Royal Colleges Science Director- Action on Sugar Saving Londoners Lives - External Advisory Board Member   Medical Research: What is the background for this study? What are the main findings? Dr. Malhotra: It is a review of all the research up to date on what is the impact of diet on health. What type of diet has the most robust evidence for weight and health and how this can be translated into policy to rapidly reduce the burden of chronic disease. Medical Research: What should clinicians and patients take away from your report? Dr. Malhotra:
  • That "low fat" diets to do not improve health outcomes and the public should stop counting calories.
  • That a high fat Mediterranean diet is more powerful in reducing the risk of heart attack and stroke than any medical treatment.
  • That it's effect is independent of cholesterol lowering.
  • That rapid weight loss through calorie counting combined with exercise doesn't only not improve health outcomes in the long term for diabetics but can also be potentially harmful by increasing CVD risk.

MedicalResearch.com eInterview with Iris Shai, RD, PhD PI of the DIRECT trial Ben Gurion University of the Negev, Israel MedicalResearch.com: What are the main findings of the study? Dr. Shai: Low-carbohydrate is as effective as Mediterranean or low-fat diets in improving renal function among moderately obese participants with or without type 2 diabetes, with baseline serum creatinine<176µmol/L (not sever renal stage).  The effect is likely to be mediated by weight-loss induced improvements in insulin sensitivity and blood pressure.
