High meter reading after exercise

Hi all. I have been diagnosed with pre diabetes / type 2. They can't make their minds up. Anyway. I am not overweight, eat virtually no carbs or sugar, drink a moderate amount (Gin & Slimline tonic) and work out for an average of 90 minutes a day (weights & cardio). I am getting really upset that my blood sugars are on average 10.3 in the mornings, after all my exercise. I do understand that the body pumps out glucose during exercise but I thought being as active as I am would see the levels reducing. My daily sugar readings are between 5.2 and 7.0. I'd be really grateful if anyone had a view or advice about exercise and whether, over time, the higher readings might reduce. For information, I am 52, 6'4 and 232lbs. Thank you in advance
 
Hello and welcome @Meltedbutter (good name btw !)

Are you eating prior to exercise and what medication are you on ?

Many thanks. It's a name I've had for ages although I don't really know where it came from! In answer to your reply, I'm not eating before exercise and maybe I should but I;m not sure what to eat that isn't cad loaded. I am not on any medications either
 
If you could give us a typical day's menu we could help you identify those pesky, hidden carbs.
 
One of the things you will (should?) keep hearing and reading about diabetes is that we are all different.
This is definitely true with regard to exercise.

In general, I find longer cardio exercise decreases BG and shorter resistance training increases BG.
For me, this means spin class and running on a treadmill for 30 minutes reduces my BG whereas climbing and weights increase my BG.
There are some things which feel like outliers such as HIIT or running outside which are definitely cardio but they usually raise my BG. I think this is due to the short periods of exercise during HIIT and the added stress of weather, uneven pavements and steep hills when running outside.

However, for the next 24 to 48 hours, my BG is usually lower. This is due to the glucose release you mention - if the body releases glucose during exercise it has less to release until it has refilled its reserves.

Of course, if I then eat a carb heavy meal after exercise, this may refill my reserves quicker and I see a rise rather than a fall the next day.

Finally, on the "we are all different" topic, it depends how fit we are. I can walk for 15 miles and have no impact on my BG whereas someone else may use walking for 20 minutes as a way to lower their BG. And it is different for different types of exercise: a marathon runner is unlikely to see a BG change when they go for a 30 minute jog whereas I know I definitely will.
 
In terms of food, a typical day is two boiled eggs and some ham for breakfast, tea x 2, lunch is usually some grilled chicken with tomatoes or half an avocado, a bottle of carbonated water. Dinner is either salmon, chilli (no beans), steak, chicken, always with roasted brussels/asparagus, broccoli (salt, pepper and a little olive oil). No rice, bread, potatoes or pasta. Pretty boring really but it's tasty.
 

The issue with not eating before exercise is that your liver will respond by giving you a dump of glucose to help with the extra activity so eating something, whether it's an omelette or something else low carb then at least your digestion has something to help fuel with.
 

Many thanks for the detailed and insightful overview. I completely agree that we are all different. I guess it is finding that balance to this is the key. I was very interested in what you said about HIIT training as this wasn't something I knew. I'm not a runner per se (although I was county cross country champion many moons ago. My preference is circuits and Spinning. When the weather is better I'll be out on the road bike a lot. I will have to look at re-appraising my workouts and see if I can regulate the glucose release. Very many thanks indeed for the post. Definitely food for thought.

Hello and welcome to the Forum Here is the Basic Information we give to new members and I hope you will find it interesting and helpful.

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 235,000 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 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.
