| Erm....not necessarily true. Whilst insulin plays a role in the storage of fat, it's not as potent as initially believed. Insulin resistance also doesn't particularly feature in T1s who eat a balanced diet and exercise regularly. Insulin resistance DOES occur in T2s, but that's rather obvious - T2 is effectively a disease whereby the individual becomes resistant to insulin, and needs to suppliment their own insulin supply either with OHAs or insulin, or alternatively by going on a restricted diet and high exercise routine. There's a strong relationship between cholesterol and insulin levels, because the majority of people with T2 have high cholesterol levels, which suggests that high cholesterol is a symptom, rather than a cause, of insulin resistance.
A well controlled T1 will put on weight simply because insulin will make you put on fat - see the thread in the Type 1 board. However, this is the same for any individual, diabetic or not. Provided you eat a balanced diet and exercise regularly you shouldn't put on weight - after all, with insulin injections you're simply replacing what your body would be producing anyway - 'a lot' of insulin is the amount of insulin you personally need that causes a hypo, and the amount of insulin required varies according to personal weight, food consumed, exercise performed and personal metabolism.
A diabetic who takes a lot of insulin and a lot of carbs WILL put on weight simply because they're taking in far too many calories - instead of eating to keep their body going, they're actually eating to counteract the insulin, which is completely wrong since you should take insulin to counteract what you eat. In other words, the nonsense about diabetics should stuff themselves with loads of starchy carbs is plain rubbish. An ND who eats loads of carbs will obviously have a pancreas that will produce enough insulin to cover this, but they'll put on weight. This isn't because of the volume of insulin, it's because of the number of calories. It's the same for a D too.
Bottom line - don't inject insulin and then eat an appropriate amount to stop a hypo - work out what you're eating, then take the appropriate amount of insulin to stop a hyper.  |
