27 Jun 2019 --- Nestlé Health Science (Nestlé) is piloting OptiJourney, a weight management program for Type 2 diabetics and prediabetics, in six English Tesco stores. The program involves an intake of just 800-850 total calories a day, to be consumed in the sole form of Optifast shakes, bars and soups for 8-12 weeks. OptiJourney is based on a DiRECT study which found that a quarter of participants on a similarly low-calorie diet maintained a weight loss of over 10kg and a third of participants achieved remission from Type 2 diabetes after two years.
