We Anglophones have reasons for adopting strange diets. Increasingly, we live alone. We have an unprecedented choice of foods, and we're not sure what's in them or whether they're good for us. And we expect to customize practically everything: parenting, news, medicines, even our own faces.

The next frontier in nutrition will be about reconfiguring diets according to individual specific physiology, lifestyle, and health goals.

Omega-3 fatty acids are essential nutrients that we must get from our diets because our bodies cannot make them; they are crucial for early brain development, and there is much evidence that they promote cardiovascular health and cognitive function.

Our food is safer and our diets are more diverse than ever before; production methods are becoming increasingly sustainable, clean and efficient; and we are constantly becoming better at protecting biodiversity.

I don't really believe in diets. I love food... If I deprive myself, I'm going to want it more. I snack on yogurt, raw cashews and cherry tomatoes.

I don't believe in strict diets or starving yourself; eat three meals a day. I believe in eating a good breakfast, a good lunch and a light dinner. Eat breakfast like a king, eat lunch like a queen, and eat dinner like a pauper. Your ultimate goal is to eat all the basic food groups in those three different meals.

I have never been one to count calories. I have a lot of friends in the fitness industry and understand girls who do crack down on diets, but I am not like that.

I don't do very well with extremes of any kind - extreme diets, extreme fitness - so moderation makes a lot of sense, and Hershey's has really great portion-friendly desserts to help people incorporate treats into their lifestyles so they don't feel like they're depriving themselves and are still living a balanced life.

Almost 70 per cent of your fitness battle is won the day you realise what your body needs and when. I've made my own diets, and I decide for myself what works for me.

Diets play with your mind rather than your body, so if I'm doing a diet, I think about food more than if I'm just eating normally.

I don't believe in diets. I don't believe any diet ever works.

Some antiquated diet books will tell you to shun all fats if you want to lose weight, but in reality, it's not healthy to eliminate fat from our diets altogether.

I don't really go on diets because when I go on a diet, my brain stops working. I mean, really, that's all I think about: what I can eat, what I can't eat. I sort of decided that's not what I want to do with my time on this planet. It's not it.

I don't believe in diets. They don't necessarily work. What they do is scrub your weight down, but as soon as you finish, you naturally go back up. I keep everything in my diet - gluten and sugar - I just cut it down a little bit and train more. It's not rocket science.

I inherited my weight problem from my mum. She was always on diets. If there was a box of chocolates in the house, she'd eat half a chocolate, then put the other half back. She loved me, but she did encourage me to diet in my teens.

The Dorm Room Diet is nothing like the conventional diets you may have tried in the past. It offers guidelines for creating a healthy lifestyle on your own, without the daunting restrictions of a quick-fix diet.

If you continually diet, you are putting your body in a quasi-famine situation. It slows your metabolism down and breaks the thermostat. Diets don't work. They don't help you understand why you're eating more than your body wanted in the first place.

Most diets would have you cutting things out from your diet; they are about denial and discipline.

My biggest regret is putting my body through fad diets - Atkins, cleanses, the hCG diet.

I've had weight issues all my life. I've been on all the diets: Atkins, liquid protein, Scarsdale diet. Now I go to the gym often. I'm always on the StairMaster, and I do weights.

We always think of a diet with a big groan. But I think diets are fun. I think it is an American pastime for a lot of women.

I don't do faddy diets any more. I once did a no-carbs diet a few years ago but it made me depressed. I couldn't be doing with that!

Do not suppose, however, that I intend to urge a diet of classics on anybody. I have seen such diets at work. I have known people who have actually read all, or almost all, the guaranteed Hundred Best Books. God save us from reading nothing but the best.

My kids know there's no candy, no soda, until the weekend. Those are the days they get to indulge in their sweets. We're big on organic food. I'm not a diet guy; I don't believe in diets. I just believe in a great meal plan.
