As with any weight loss diet, if you have any reason for concern you should always check with your doctor first.
Do NOT do the diet if you:
Are under 18 years of age.
Are breastfeeding, pregnant or undergoing fertility treatment. However, if you are pregnant and there is a risk of (or previous history of) gestatitional diabetes.
Are underweight and/or have a history or suspicion of an eating disorder.
Have a significant psychiatric disorder or a history of substance abuse.
Are under active medical investigation or treatment, or have a significant medical condition affecting your ability to comply with a diet.
Have had a recent cardiac event, myocardial infarction or cerebrovascular accident (less than three months ago) or other heart abnormalities.
Have uncontrolled heart disease, uncontrolled hypertension, or kidney failure.
Are unwell, have a fever, are frail or recovering from significant surgery (less than six months ago).
Cautions – discuss with your doctor if any of the following apply, before doing our program:
You have a significant underlying medical condition.
You are on insulin – you will need a detailed assessment and education by a health professional to plan a suitable reduction in medication/insulin to avoid a potentially dangerous drop in blood sugar (hypo).
You have type 2 diabetes and are on medication. Your medication may need to be reduced or stopped as blood sugars improve and to avoid hypos.
You are on certain diabetic medication and have ‘hypoglycemia unawareness’.
You are on blood pressure medication. This may need to be reduced or stopped as blood pressure improves.
You are taking other medications, e.g. warfarin.
You have moderate or severe retinopathy; you will need extra screening within six months as retinopathy can sometimes get worse when blood sugar improves.
You have epilepsy (though there is some evidence that a low-carb keto diet can improve epilepsy).
You are pregnant: clearly avoiding low-calorie diets is wise.
