Julia lost 11kgs in 4 months

"Whilst the medication undoubtedly helps with the weight loss, for me, the biggest support is the counselling. My coach, Maria is really supportive. To have someone that gives you ideas on what you can change and then you hold yourself accountable which is what I think is needed for long term success."

“This program has completely changed my life, because I am a diabetic and had previous difficulty in losing weight. Now, I eat much healthier, drinking more water, exercising and being optimistic. My sleep and the level of energy has improved a lot, I don’t crave junk food, fizzy drinks, sweets, I don’t make anymore late night visits to the kitchen and so many other positive changes.”
