Does training help the body burn fuel more efficiently?

An important part of getting fitter, and improving both speed and endurance is training the body to burn fat at higher levels of intensity. This is really important for athletes who do the things I like doing – running (because they can go faster and further) and mountaineering (because mountaineers don’t have very good access to food to top up their limited carbohydrate stores).

One of the advantages of having diabetes is that I can observe how much carbohydrate I need to eat to keep my blood sugar stable. Does this mean that I have an insight into how well my body is adapting to burning fat? Can this help anyone else?

Data Training

Diabetes as Art

I’ve been going to the monthly quantified self meetup whenever I can. They are really interesting evenings. At each evening, three people present on any aspect of self quantifying they have been doing. Given that I have diabetes and track a lot of data these days, I feel like there’s stuff I can learn from the presentations. Even if they’re not relevant to me they are normally fascinating, and this techy geeky world is something I wouldn’t have discovered without my diagnosis (the gift of diabetes keeps on giving…!).

At the last meetup a photographer called Travis Hodges gave a presentation on his work. He is doing something called “follow me” which is where he took a photo of someone, got them to tweet one of their friends and then took a photo of them. The chain goes on. The collection was so successful that he was asked to do an exhibition in Brixton, and decided to do portraits of self trackers, their devices, their motivations and their data.

Diabetes and being ill don’t mix

I’ve just come out of a two week long cold. Despite evidence to the contrary (I got diabetes six months ago), I think of myself as someone who never gets ill. So getting a cold and feeling low on energy and not wanting to run was a real blow. Not least because my fund raising page reminds me that I only have 54 days left to the Marathon. Given that I want to run it in a very challenging time, two weeks of almost no quality training is a real blow. I’m still waiting for comments on whether I should run the marathon in a Onesie by the way. So far two people have commented, and that’s not quite enough to encourage me to do it!

Does doing A LOT of running help blood sugar control?

This is where it all started - running in Chamonix in September made me want to do an ultra marathon in Chamonix. I found out yesterday that I have a place in the CCC - a 100km race from Courmayeur in Italy to Chamonix. It includes 7500m of vertical height difference.

Waking glucose – it was perfect for a few weeks round the start of December

I’m still in the honeymoon phase. That means my body produces a small amount of its own insulin and is therefore capable of controlling my blood sugar to some extent. In theory, if I was sensitive enough to this insulin, could my body control its sugar levels like a healthy person? Who knows!

For a few weeks before Christmas, I was consistently waking up with blood glucose readings of between 5 and 6 mmol/litre. That is basically PERFECT. It’s what a healthy person would wake up with. I started noticing that, and I also noticed that it was often 5.7 regardless of what level it was when I went to bed.

Over the past month it’s been between 6 and 7 when I wake up. That’s still good, but not PERFECT. I’ve noticed the change in trend and want to know why.

Wake up glucose

The blue line in the chart above shows my average waking up glucose. You can see a golden period before Christmas, where average waking up glucose was about five despite average glucose when I went to bed (red line) being higher. For the rest of the time, glucose on waking is pretty well correlated to glucose when I went to sleep. This suggests that my long acting insulin (Lantus – I take it before bed and it acts like “background” insulin, staying in my system for 24 hours or more) dose is about right.

What explains the really good waking glucose levels, and what explains them not being quite as good now? Please forgive the very busy chart below – it shows average waking and bed time glucose, how many minutes of running I did a day on average and average grams of carbs I eat before bed.

Factors affecting wakeup glucose

It’s not lantus

My Lantus dose has been steadily dropping as I seem to become more sensitive to insulin over time. (You can see I took it down to just four units while I was skiing, but it’s back up to 5 now.) There’s no obvious correlation between Lantus dose and waking blood sugar.

It’s not what food I eat at bedtime

If my blood sugar is a bit low when I go to bed, I normally eat something so that I don’t get a hypo. Am I eating more before bed now than I was? You can see from the chart that the opposite is actually true – I was eating slightly more before bed at the same time as my waking blood sugar was best controlled.

Could it be the running?

The other line on the chart is the number of minutes I’ve run a day, on average. In the lead up to my ultra, I was doing a lot of running (between 50 and 70 miles a week, or over 40 minutes a day on average). I wonder if doing all this running makes my body sensitive enough to insulin to enable my own insulin production to control my blood glucose to the optimal level? I’m going to ask my doctor.

The chart below shows my waking blood glucose, with periods where I’ve done over 35 minutes a day of running on average. You can see that there’s a rough correlation between waking with blood sugar of between 5 and 6 and me doing lots of running.

Running vs waking BG

I’m ramping up my running training again ahead of the London Marathon. I managed ten miles yesterday, 14 today and hopefully will do eight tomorrow. I’ll continue to monitor my waking glucose (of course!) and will be interested to see whether it starts coming in between 5 and 6 again.

I feel great to be running a lot again, and if it helps control my blood sugar better then that’s a nice bonus!

Skiing with type 1 diabetes

I’m currently in Chamonix for my first skiing Christmas. I was ridiculously keen to go skiing again. But also aware that it was my first time skiing with type one. One of the main reasons I started all my running was so that I could understand my blood sugar control better to prepare me for skiing. I’d like to do things like this again safely with type 1, so I’m really motivated to control the condition.

My second honeymoon

If you told me last October that I’d be having a second honeymoon within a year I wouldn’t have believed you. But here I am enjoying the “honeymoon period” in type 1 diabetes. The photo above is from my first honeymoon to Patagonia. I put it in the post cos it’s more interesting to look at than all the charts!

When I first got diabetes, I thought I’d be able to do loads of clever things with my data to get good at managing it. I’ve been collecting data enthusiastically, but making sense of the mountain of data I’ve produced is difficult. Plus I spent two weeks not recording anything at the start of November because I was sulking. Sulking because my smartphone app which I use to record all my data was bought by another company and they seriously dis-improved the user experience as a result. I was shocked at the emotions I experienced when something I use and depend upon every day was changed: I was more angry and upset about that than I was about being diagnosed with diabetes in the first place! So were many other users if the number of horrendous reviews on Google Play were anything to go by. Luckily they fixed the problems, but that explains the gap in my data below.
