Right now we are Android only - and specifically only with phones that have an NFC and Android version 6.0 and higher. We will be releasing iOS version later this year so join the mailing list for updates on that.
When you eat carbohydrates such as sugars your body breaks them down to glucose, which is the shortest chain carbohydrate. The glucose then travels around your body and is used for energy by your brain and body. However, if there is more glucose than immediately needed it gets pushed into your fat cells. The amount of glucose in your blood is called blood glucose or blood sugar level.
The main factor is the food you eat - especially sugary and carby foods. Other things that can affect sugar levels are exercise (when you exercise your body releases your glycogen stores to give you more energy) and stress levels (when your stress levels are high your body goes into “fight or flight mode” also releasing those glycogen stores). Spikes from exercise are not a problem, because your muscles are immediately using up that glucose.
When your sugar levels increase this causes insulin levels to increase. Insulin pushes glucose into your fat cells. So higher levels of insulin will cause more weight gain. Keeping your sugar levels balanced will reduce the amount of insulin your body produces and so reduce the amount of glucose that gets pushed into your fat cells. Also, if you no longer get sugar crashes, you’ll no longer get those tricky food cravings. This also makes dieting much easier.
When your sugar levels are crashing, you may become distracted and lose focus. Your body is worrying that your sugar will get too low and so wants you to focus purely on finding food (it's lower down Maslow’s pyramid of needs). By keeping your sugar levels balanced, you’ll not get distracted by your stomach, and will have achieved better focus throughout the day.
Crashing sugar levels, especially when they fall below your baseline (the level when you wake up) can make you hangry and irritable. Another downside of these crashes is that having the discipline required to fight these crash cravings all the time can be very hard.
There are many factors involved, including genetics, lifestyle and insulin sensitivity. However, what seems to be the most interesting and a strong predictive factor is the gut microbiome (the bacteria in your gut). This is a hot area of study with cutting edge research coming out every week.
Prices start from £139 for Android users. We are currently not offering an iPhone version - but if you join the mailing list we will let you know when we release it.
This is really up to you. Some people want a new one every month or two as an aid to keep their diet on track or further optimise it each month. Lots of myLevels customers have asked for a new sensor after 6 months as they started to get curious about new foods they've started eating. Some people felt they learnt enough the first time so that's all they need. So it's really up to you - try the first one and then see when you get another urge. We'd recommend though for everyone at least once a year as your microbiome (your bacteria in your gut) changes over time and with new situations so your responses could be different a year later.
