Celebrity health check: Karen Koster, TV Presenter

Do you have any ailments/health concerns?

No, thank God. Overall, myself and my family have been lucky healthwise, touch wood.

How would you rate your energy levels?

I would say good, if I've been looking after myself. Although last night, I got to the gym and then begged my trainer to let me go home because I was so tired. But that's because I worked the whole weekend. If I've been eating and sleeping right and had the weekend off, then I've enough energy to keep up with my job.

Do you get your five a day?

Yes, though it probably leans more towards fruit than veg. I'm trying to up my intake of veg, but fruit is just handier and gives me my sugar kick.

How would you rate your stress levels?

Much better than, say, five years ago. This job can be stressful in that you're always against a deadline. But now I try to outsmart stress by being super organised.

How's your sleep?

Good. I'm kind of obsessed with getting a good night's sleep. I feel off if I've had less than seven hours. I've got ear plugs, eye masks and blackout curtains.

Do you take vitamins/supplements?

Yes, every day I take a multivitamin and a silica supplement to try and coax my hair to thicken up.

Do you exercise?

Yes, twice a week I train with personal trainer Alan Byrne, based in Sandyford. I wish I'd never told him that I'm getting married next year as he's way too motivated, I'm struggling to keep up! I'm also determined to become addicted to running.

Do you cook from scratch?

As much as I can. At the moment it's about 40pc me, 40pc Marks & Spencer and 20pc eating out.

How many alcoholic beverages would you consume in a week? I would have maybe three to four during the working week over the five days. And I'm not saying how many over the weekend! But let's just say that I'm a regular contributor to my local bottle bank.

Do you have any health goals?

Apart from making running a regular part of my regime, I would say my goal is to live long and healthy. I know I'm never going to be a smaller size, but I like looking fit and strong.

Rate My Diet -- What

I ate today:

Breakfast: Slice of rye bread, toasted with peanut butter. Orange juice and tea.

Lunch: Baked chicken breast with broccoli, tomato and cucumber salad.

Dinner: Steak with steamed veg and a potato rosti.

Snacks: One apple.

Beverages: Two litres of water, one coffee, two teas and a glass of red wine.

Elsa's Verdict: Karen, you appear to have a healthy and balanced diet and you look after your overall health, so good on you.

In terms of your diet, nut butters are a great source of protein but I would suggest you try using almond butter instead of peanut butter as it contains less saturated fat and more minerals and fibre. You can buy it from health stores.

Fresh orange juice, while healthy, should be drunk in moderation as it can spike blood sugar levels.

You also like your wine, which isn't a problem, but I would suggest that you have at least two alcohol-free days per week and try to stick to no more than seven glasses per week.

You take silica to thicken your hair, which is a good natural option. I'd recommend that you increase dietary sources of this mineral as well by eating more vegetables (including their skin).

Good sources include peppers, leeks, green beans, chick peas and cucumber.
