Before you start
The GM diet is very low in calories and protein on several days, and no clinical study has tested it. Do not follow it if you are pregnant, breastfeeding, under 18, have diabetes, kidney disease, heart disease, low blood pressure or a history of disordered eating, or take regular medication, unless a doctor has agreed. Stop and eat normally if you feel faint, dizzy, confused or unwell.
