Low Carb and Reducing Insulin

Hello,

I'm trying to start eating fewer carbs (contrary to my nefrologist's advice) but I'm really struggling to know what to eat. The most important thing to me is taking care of my kidneys, which are working at 33%, so I need to be careful with potassium and phospherous too.
I inject 50 units of insulin every morning, am I supposed to change this when eating hardly any carbs? That's another thing too, what is "low"? Am I not supposed to be having any carbs at all? (That's what I've been doing and I keep having hypos and reaching for my emergency biscuits)..

Any advice would be much appreciated!

Thanks

well 'low carb' is generally said to be anything less than 135g carbs per day. Do you have any idea how many carbs you were having before? If I were you I would work my way down from there gradually. Some here have less than 20g a day, but I think that's too great a drop for you to start with when you are taking insulin. Just my opinion.

I hope someone else can help you with reducing insulin.

You need very clear answers to these, and other questions that you dont even know to ask (yet :) ) before you make any changes to your carb intake.

Going low carb when on insulin is a very different thing than going low carb when on other meds or no meds at all.

Since i dont take insulin, i cant suggest much, but i can ask a few questions, and hopefully some low carbing insulin users will be along to help soon :).

In the meantime:

Are you on mixed insulin? Or a basal/bolus regime?
Do you already know how to carb count?
How many grams of carbs are you currently eating?

Please don't make any drastic changes til you have gathered enough info to know exactly what you are doing.

You can set your carb limit wherever you want. I eat less than 20 a day and take very small doses of insulin in order to do that. When eating vlc most need to bolus for protein. I bolus for 1/2. So if I'm eating 20g I bolus like it's 10 carbs.

I had kidney stones and I too try to take care of them. I eat very few nuts or dark leafy greens. Never spinach. That's the worst food for stones. I drink lemon water to help flush them as well. I'm not sure kidney failure requires the same diet as stones but I would think it wouldn't hurt. I also keep my animal / fish protein low.

What can you eat low carb?
Any kind of protein. Chicken, turkey, egg, beef, lamb and all kinds of fish
Above ground non starchy veggies. Salad greens, mushrooms, celery, asparagus, radish, scallions, bok choy etc.
Healthy fats like avocado, olive oil, olives, nuts, cheese

Depending on how many carbs you were eating and how many you plan to eat will determine your insulin needs but if you drop some carbs you'll need to drop your insulin, especially if you're having hypos. Better to error on the side of caution and take less.

Do you carb count? Are you comfortable managing your own insulin? Are you on basal bolus? Those would both likely to be changed.

I think that before even starting to think about low carb you should analyse the insulin you are using - what type it is and the amounts you are using, and the food you are eating.
Knowing your requirements now should help you to organise any changes you intend to make, but just going in and changing one thing without adjusting others seems unlikely to give a good outcome.

Thanks for the replies! Wow so much to think about !

Are you on mixed insulin? Or a basal/bolus regime? I don't even know what this means :(
Do you already know how to carb count? Not really
How many grams of carbs are you currently eating? According to myfitnesspal 120g per day

"What can you eat low carb?

This is my problem.... lots of those things are either too high in potassium, or too high in phosphorous, I feel like I have no food choices except the 200g of pasta I'm supposed to eat almost every day (diet my nefrologist gave me)

I have to see my endocrino in a couple of weeks, I'll ask her about insulin/carbs although I know the answer already..."you must eat carbs!"

There is an online carb counting course you can take online - but (frustratingly!) i don't have a link i can give you.

Hopefully someone else will have it, and be kind enough to post it.
@noblehead for some reason i am wondering if you have the link...?

Basal insulin is a background insulin that keeps your blood glucose levels steady if you dont eat.
Bolus insulin is a fast acting insulin that controls the blood glucose rises after food.
Many insulin dependent diabetics inject basal and bolus separately during the day, in order to eat what they want, when they want.

Mixed insulins are a combination of basal and bolus in a single injection (usually 2 jabs a day) which mean that you are told to eat set portions of carbs every day, to match the insulin.

Hope that helps.

Thanks very much for that input, No2D, very helpful. 1-4 I'm doing better now , number 5 I'm trying to do, each day my understanding and recording of things is getting better. There is one thing, people say "test test test" but I haven't got an unlimited supply of strips... the nurse gives me 50 for free, for about 3 months and they are astronomical to buy from the chemist , so I'm kinda limited a bit as to how much testing I can do

I'm feeling better about things though, thanks to people on here, a few weeks ago Iwas in a very very bad place, don't want to end up there again, so thanks again everyone!

You could try asking for more, explaining that you hypo sometimes and need more than 50 strips for 3 months as you are on insulin. (I wouldn't mention the low-carbing though, she might not be open to the idea of a change in diet if it's going to cost the practice more money ;))

Hi, it's called Lantus

Lantus is a long acting or basal insulin. The job of a basal insulin is to keep blood sugar flat when you aren't eating or taking bolus insulin. But in a type 2 diabetic it may also be intended that it takes the edge off of post prandial rises. If that's the case then your dose might need adjusting to take account of the reduced carb intake. You should discuss this with your nurse.

@CluelessJoe

Hello Joe and welcome to the Forum :) Here, as mentioned above, is the Basic Information we give to new members and I hope you will find it useful. Ask as many questions as you need to and someone will be able to help.


BASIC INFORMATION FOR NEW MEMBERS

Diabetes is the general term to describe people who have blood that is sweeter than normal. A number of different types of diabetes exist.

A diagnosis of diabetes tends to be a big shock for most of us. It’s far from the end of the world though and on this forum you'll find well over 147,000 people who are demonstrating this.

On the forum we have found that with the number of new people being diagnosed with diabetes each day, sometimes the NHS is not being able to give all the advice it would perhaps like to deliver - particularly with regards to people with type 2 diabetes.

The role of carbohydrate

Carbohydrates are a factor in diabetes because they ultimately break down into sugar (glucose) within our blood. We then need enough insulin to either convert the blood sugar into energy for our body, or to store the blood sugar as body fat.

If the amount of carbohydrate we take in is more than our body’s own (or injected) insulin can cope with, then our blood sugar will rise.

The bad news

Research indicates that raised blood sugar levels over a period of years can lead to organ damage, commonly referred to as diabetic complications.

The good news

People on the forum here have shown that there is plenty of opportunity to keep blood sugar levels from going too high. It’s a daily task but it’s within our reach and it’s well worth the effort.

Controlling your carbs

The info below is primarily aimed at people with type 2 diabetes, however, it may also be of benefit for other types of diabetes as well.

There are two approaches to controlling your carbs:
  • Reduce your carbohydrate intake
  • Choose ‘better’ carbohydrates
Reduce your carbohydrates

A large number of people on this forum have chosen to reduce the amount of carbohydrates they eat as they have found this to be an effective way of improving (lowering) their blood sugar levels.

The carbohydrates which tend to have the most pronounced effect on blood sugar levels tend to be starchy carbohydrates such as rice, pasta, bread, potatoes and similar root vegetables, flour based products (pastry, cakes, biscuits, battered food etc) and certain fruits.

Choosing better carbohydrates

The low glycaemic index diet is often favoured by healthcare professionals but some people with diabetes find that low GI does not help their blood sugar enough and may wish to cut out these foods altogether.

Read more on carbohydrates and diabetes.

Over 145,000 people have taken part in the Low Carb Program - a free 10 week structured education course that is helping people lose weight and reduce medication dependency by explaining the science behind carbs, insulin and GI.

Eating what works for you

Different people respond differently to different types of food. What works for one person may not work so well for another. The best way to see which foods are working for you is to test your blood sugar with a glucose meter.

To be able to see what effect a particular type of food or meal has on your blood sugar is to do a test before the meal and then test after the meal. A test 2 hours after the meal gives a good idea of how your body has reacted to the meal.

The blood sugar ranges recommended by NICE are as follows:

Blood glucose ranges for type 2 diabetes
  • Before meals: 4 to 7 mmol/l
  • 2 hours after meals: under 8.5 mmol/l
Blood glucose ranges for type 1 diabetes (adults)
  • Before meals: 4 to 7 mmol/l
  • 2 hours after meals: under 9 mmol/l
Blood glucose ranges for type 1 diabetes (children)
  • Before meals: 4 to 8 mmol/l
  • 2 hours after meals: under 10 mmol/l
However, those that are able to, may wish to keep blood sugar levels below the NICE after meal targets.

Access to blood glucose test strips

The NICE guidelines suggest that people newly diagnosed with type 2 diabetes should be offered:

  • structured education to every person and/or their carer at and around the time of diagnosis, with annual reinforcement and review
  • self-monitoring of plasma glucose to a person newly diagnosed with type 2 diabetes only as an integral part of his or her self-management education

Therefore both structured education and self-monitoring of blood glucose should be offered to people with type 2 diabetes. Read more on getting access to blood glucose testing supplies.
