> Insulin is the Miracle-Gro for your fat cells. A child with new onset type 1 diabetes — unable to make enough insulin — will invariable lose weight until receiving treatment, no matter how many calories she consumes. Give that child the right amount of insulin, and weight trajectory returns to normal. Give that child (or an adult with type 2 diabetes) too much insulin and excessive weight gain will predictably result. This is just Endocrinology 101. This is incorrect. Giving too much insulin to a type 1 diabetic causes rapid death, not weight gain. Giving no insulin to a type 1 diabetic causes weight loss because most calories leave through urine rather than getting used or stored, not because insulin is "miracle-gro for your fat cells".
