Liquid diets have had an image problem â€” the idea of losing weight by mixing sachets of powder into meal replacement milkshakes or soups makes dietitians very unhappy.
They worry that losing weight too quickly could be bad for you, and such plans donâ€™t teach you how to eat healthily afterwards.
Indeed, many people do quickly put all the weight back on.
And then there are the pyramid-selling techniques behind some of these liquid diets, which have caused doctors to be especially cautious about making use of them.
But that poor image could be due a rethink following compelling new research suggesting low-calorie liquid diets can tackle obesity and reverse type 2 diabetes.
