Many of us will try out the latest diet or fitness fad in the quest for the body beautiful.
But when it comes to key facts about our own health, our knowledge is often lacking.
In fact, most are pretty clueless about their health – with more than half admitting they don’t even know their own blood type, a study has found.
Millions have no idea what their cholesterol levels are or what their normal blood pressure or BMI are.
What weight is healthy for your height and how many calories and glasses of water should be consumed daily also leave many stumped.
The survey of 2,000 UK adults also reveals that 35 percent of people have never had a medical check up.
Meanwhile, more than four in ten admit it would take a health scare before they really start to worry about things issues like cholesterol levels or blood pressure.
And the average person doesn’t start to take more notice of their health and lifestyle choices until they reach the age of 47.

A spokesperson for Healthspan, which commissioned the research, said often people ignored their health until it becomes an issue.
‘People still seem to know little about heart health. As a result, unless it is something you know you need to keep an eye on, many would struggle to tell you what their blood pressure or cholesterol levels are, or even what they should be in order for them to be healthy.
’We carry on with our lifestyles without any real knowledge of the impact it could be having on our general health, as well as to important organs such as our heart.
‘But waiting until a problem presents itself could be too late to do anything about it.
‘By finding out about key areas of your health early on, and keeping an eye on things such as your blood pressure, vitamin D and cholesterol levels, you could prevent any health problem occurring before it even starts.’
Three-quarters admit they have no idea what their cholesterol levels are, with almost four in ten saying they have never had them checked.
Almost half also said that even if they did, they don’t actually know what is considered healthy.
