Morning everyone

Great forum, I've learnt lots from all you lovely people!

I was diagnosed T2 about three years ago, am aged 46, currently on 2000mg Metformin and looking at possibly going on more medication as glucose control isn't great still. Slightly overweight but trying to do something about it :-).

I've recently got into road cycling and reaching the distances (50 miles +) where hydration and nutrition become very important. When cycling with friends I see them guzzling energy gels/tablets/drinks like they're going out of fashion and obviously I steer clear of them as they are basically just sugar but suffer fatigue and struggle to keep up.

So I was wondering if anybody here was involved in cycling or other endurance sports and had any advice on the subject?

Thanks in advance
 
Hello and welcome to the forum. Tagging @daisy1 for the info pack offered to all newcomers.

The LCHF lifestyle (Low Carbohydrate High healthy Fats) is said to be very good for endurance sports.
Perhaps you could look at Prof. Tim Noakes who is an expert (some would say the expert) on sports nutrition.
This lifestyle also suits many people with Pre Diabetes and Type 2 Diabetes.

Have a wander around the forum and ask as many questions as you like.

Hello Jambo and welcome to the Forum :) Here is the Basic Information we give to new members and I hope it will be useful to you. Ask as many questions as you want and someone will 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 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.

You may also be interested to read questions to ask at a diabetic clinic.

  • Low Carb Program - it's made front-page news of the New Scientist and The Times. Developed with 20,000 people with type 2 diabetes; 96% of people who take part recommend it... find out why

  • Hypo Program - improve your understanding of hypos. There's a version for people with diabetes, parents/guardians of children with type 1, children with type 1 diabetes, teachers and HCPs.

If you a veggy my apologies but to keep me going I'll eat a large pack of pork scratchings They are high in protein fat and salt. I drink plenty of water too.
 
I've recently got into road cycling and reaching the distances (50 miles +) where hydration and nutrition become very important. When cycling with friends I see them guzzling energy gels/tablets/drinks like they're going out of fashion and obviously I steer clear of them as they are basically just sugar but suffer fatigue and struggle to keep up.
I have struggled with the problem of fuelling my runs, which however are very short. In theory by eating very LCHF and entering a state of ketosis you could become fat adapted and able to fuel your athletic efforts largely from your own stored fat, thus avoiding the need to keep re-fuelling with carbs. Very convenient for running ultras! Some very successful long distance competitors report using this method and finding it works very well for them. Very few, perhaps none, have reported success over short distances while using this system.

On the other hand Dr Bernstein, while advocating low carb, is very against a low protein high fat diet. He believes it leads to muscle wastage and general ill health. He envisages taking on extra carbs while training to fuel your efforts. Unfortunately for those not insulin dependant, most of his advice is directed at those who are. He is still training quite vigorously at the age of 84, having been T1 most of his life, but I don't think he goes in for prolonged exercise.

I bought "the Art and Science of Low Carbohydrate Performance" by Jeff Volek
https://www.amazon.co.uk/Art-Scienc...TF8&qid=1533321131&sr=1-3&keywords=jeff+volek
It is a good thing it is a slim volume available at a reasonable price, as I was very disappointed in it. IMO Mr Volek tries to blind the reader with highly suspect science, which he makes sound as complicated as possible. He offers only a few case studies of athletes who are successfully fat adapted, and many of those attribute much of their success to taking a mysterious supplement made from wasps.

I suggest you post a query in the Fitness Exercise and Sport section lower down: https://www.diabetes.co.uk/forum/category/fitness-exercise-and-sport.33/
There are quite a few T1s doing long exercise sessions. Not so many T2s.
