Nutrition for weight loss surgery is very different to normal healthy eating and weight loss. Our specialist dietitians Eva Tamrakar and Shannon Overs are experts in the nutrition management of weight loss surgery, particularly gastric banding, sleeve gastrectomy, Roux-en-Y gastric bypass, and omega-loop gastric bypass. Bringing over 12 years nutrition counselling experience to SIOS, Eva and Shannon are highly committed to ongoing professional development and education to provide their clients with individualised, up-to-date, evidence-based dietary care.
