Type 2 diabetes is reversible Type 2 diabetes is potentially reversible using 8-week, very low-calorie diet followed by careful weight management. According to an online report published March 21, 2016 in the journal Diabetes Care by Dr Sarah Steven of Newcastle University, UK, at the time of diagnosis, everyone should be told that type 2 diabetes is potentially reversible by way of substantial weight loss. In the study, 30 overweight diabetics reduced their weight following an 8-week mostly liquid diet of 600 to 700 calories a day and 40% of them achieved an average fasting plasma glucose level of less than 126 mg/dL. This can be equated to medical bariatric surgery. Subjects were allowed to eat non-starchy vegetables and drink at least 2 liters per day of calorie-free beverages and to maintain normal activities.
