I am considering ordering the diet chef on saturday and wondered if it really works? I have an underactive thyroid and am on tablets for it which is enabling me to lose 1-2 lbs a week but i need to lose more, i have had 5 kids and put on more weight with all of them and am now really unhappy with how i look and my level of fitness but i do not want to waste time and money on something that doesnt work, can anyone advise?
