If I’m a type 2 diabetic with severe insulin resistance, why does insulin being my sugar levels down but my insulin doesn’t?

Secondly, if I do low carb and I have to take insulin for protein to bring my sugar levels down, what is the point in lowering carbs? It seems I have to do it regardless whether it’s for carbs or protein!

Thank you so much.

Lots of maybes here, so I'm just going to hazard guesses: You're insensitive to your own insulin. If you shoot insulin you can add in more than you naturally produce to compensate, most likely. So where a type one without insulin resistance might have enough when they take 12 units to compensate for not making any, you, with insulin resistance, might need 80 units to achieve the same effect. (Random numbers, mind you).

Protein raises blood sugars a little, and slowly. Carbs raise them (much) more and potentially, faster. So it's basically, do you touch a table with your toe calmly and deliberately, or you do kick the table leg headlong at 50mph. One'd be more likely to break the bones your toe than the other. It's about speed and proportion.

Everything's relative, basically. Hope that helps!

Hi @lcarter I hope that a member who is Type2 but on insulin will come along to answer your questions.
Meanwhile I (a diet controlled Type 2) will give you my (limited) understanding of it all.

Firstly a few words of your post seem to be missing.

I think you are asking is why injected insulin brings your blood sugar levels down, but your own insulin doesn't?
This is almost certainly a misunderstanding, unless your pancreatic Beta cells have given up and so you no longer make any insulin yourself.

As a Type 2 you almost certainly suffer from insulin resistance which mean s it takes much more insulin than normal in order for it to force the blood sugar (glucose) out or the bloodstream and into the cells which either use or store it. If making all this extra insulin gets to be too much for your body, then one remedy is to use prescribed external insulin to make up the difference between the amount you make yourself and the amount that you actually need.
We are all different, so my diabetes isn't the same as that of each of my 5 moderator colleagues even though we are all T2 and mainly diet controlled.
Similarly, there are different kinds of insulin (human, porcine, synthetic etc) and withing the synthetics there are faster and slower acting insulins. But different people may react somewhat differently to a particular type of insulin from the way somebody else does. But, if you are still producing it, there is no reason to think there is anything wrong with your own human insulin - just that because of insulin resistance you are not making enough of it right now.

Now to address carbs: Carbs convert into glucose very easily and often very fast, sometimes while they are still in your mouth!
Some people, perhaps all people, produce some glucose from fats and proteins if they eat zero or very low carbs. There is a part of the brain which absolutely require glucose in order to work- so in cases of fasting or starvation our body needs to be make at least that amount of glucose even when no carbs are eaten. But the vast majority of the energy requirements of the body can be supplied by Ketones - which is why Carbohydrates are NOT an essential macro nutrient.

It's possible that in some people, they are not accustomed to 'burning fats' for ketones for energy and so their body produces a lot more glucose from proteins and fats than is actually necessary - thus they have to inject insulin to cover for the protein they eat if they are consuming nearly no carbs, but since making glucose from proteins and fats is 'expensive' and takes more time compared to doing it from carbs, the body always chooses carbs first!

So you have the choice - consume more carbs and inject more insulin, or consume few carbs and inject less insulin. The amount of external insulin needed is related to:
A). How bad your insulin resistance is.
B). How much insulin your body can still make.
C). How many carbs you eat.
D). How much protein and fat your body converts into glucose.

@lcarter , are you injecting insulin? Your profile says you are on oral meds. If this info is out of date and you are on injected insulin, please will you update your profile.
If I am mistaken , please accept apologies. It is not clear from what you have posted. Accurate meds info will enable members to give accurate and appropriate advice.

your insulin also reduces bg, and much faster than exogenous insulin because it immediately enters the bloodstream, and not into subcutaneous fat. It's just that your insulin is not enough and you have to add an exogenous one. For example, your insulin lowered bg from 20 to 16, but you need to lower it from 20 to 6 and you inject insulin to achieve this

I’m very much like you I’ve only learnt thru keeping a food diary . Unlike most a lot of vegetables are bad for me carrots and tomatoes in particular make me spike . After night fasting on 48 units insulin I’m usually between 6 and 8 . They another 48 units on a morning by bedtime no matter what I eat I’m always in excess of 10. I’ve done all the usual checked my evening sugars and they are round about 6/8 i don’t eat after 6 pm but by the time I go to bed they will be 10/12 or even higher up to 18 some times. Ive seen a dietician and the diet she gave me could have put me in a coma and she couldn’t fathom why this was happening. They always say I must be lying about what I’m eating but I’d love to go into hospital and prove my point

I’ve tried to change it on here but it won’t let me—I will aim to get to a desktop to change this as I’m on insulin. Thank you

I have to be careful also as tomatoes will spike me, carrots, beets and others. I can just about have one small cherry tomato with salad now and again. No more growing them in the garden :bored:
 
I can't risk root veg at all except very occasionally a few thin carrot shavings that appear in a stir-fry mix that I have bought as distinct from making my own. Tomatoes are also restricted to a very occasional half an unripe one. Plenty of veg that don't spike me, so those are the ones I eat.
 
I also had a huge surprise with some cherry tomatoes very early on when I switched out the carbs.. I guess we have to remember that tomatoes are fruits masquerading as veggies, or veggies masquerading as fruits...
