Extreme starvation-style meal-replacement diets can help obese adults to lose up to 22 kilograms in 16 weeks, says a new study.
Professor Clare Collins, leading Australian nutritionist, said that people obsessed with food, and those waiting for lap-band surgery, can successfully lose weight with controversial diet shakes, News.com.au reported.
Collins said that the diet must be supervised by doctors or nutritionists and one should try this at home alone.
She said side-effects could include headaches, bad breath and gall stones.
Meanwhile, Dr Leon Massage, an Australian Medical Association board member, said he did not support the use of diet shakes for patients unless they were preparing for surgery.
