Because the biological mechanisms that affect our health and well-being are so dynamic, when people change their diet and lifestyle, they usually feel so much better, so quickly; it reframes the reason for changing from fear of dying to joy of living. Also, the support that patients give each other is a powerful motivator.

I was 17 when my body started changing, and I worried about what I did wrong. I went through a period where I didn't eat at all. I also had someone who was encouraging me to take diet pills. I pushed myself to the extreme because I woke up one day and had hips - and a butt - and thought, 'Oh my gosh, I'm getting fat!'

I'm nutty for nutrition. I've become one of those people who can't stop talking about the connection between food and health. Now that I know how much changing what you eat can transform your life, I can't stop proselytizing.

My nutritionist has done a great job in changing my diet after we established I am allergic to things like gluten - I can't eat pizza, pasta and bread. I have lost some weight, but my movement is sharper and I feel great.

Adopting a new healthier lifestyle can involve changing diet to include more fresh fruit and vegetables as well as increasing levels of exercise.

If you've got a big gut and you start doing sit-ups, you are going to get bigger because you build up the muscle. You've got to get rid of that fat! How do you get rid of fat? By changing your diet.

I've realized that I'm more important than food is. I love a big slice of pizza, but I love myself more. Being thin is about changing the way you think about yourself. It's about saying that you deserve to be healthy.

By fundamentally changing how we design the places and systems that enable our daily lives, we can slash emissions way beyond the immediate carbon savings - because our own personal emissions are just the tip of a vast iceberg of energy and resources consumed far from our view.

Tesla is changing the paradigm. We're going to turn the world on its ear and create high demand through design.

Everyone designs who devises courses of action aimed at changing existing situations into preferred ones.

Meeting Marta, who she is as a person, and hanging out with her, seeing her watch my fight, screaming and cheering for me, being proud of me the same way I am proud of her, that's priceless. It was really cool. I never imagined that.

I just like hanging out with my friends, honestly. I mean, as long as I'm in good company and with cool people, and we're just hanging out and having a good time, that's usually what I like to do.

What people don't understand is joining a gang ain't bad, it's cool, it's fine. When you in the hood, joining a gang it's cool because all your friends are in the gang, all your family's in the gang. We're not just killing people every night, we're just hanging out, having a good time.

It's cool just because I've had this dream of changing the sport of swimming and it's finally happening.

Environmental advocates say that changing how much power computers and monitors use in idle mode can cut greenhouse gas emissions without requiring consumers to change their behavior.

Technological developments are changing the way we live, and there is much talk of digitalisation and the disruptive business models enabled by smart phones, tablets, computers, and the 'Internet of things.'

The way we live is changing. Each year, our free time shrinks a little more as computers clamor for an increasing percentage of our attention.

I grew up before computers. Computers are changing things, not all for the good.

The iPhone is made on a global scale, and it blends computers, the Internet, communications, and artificial intelligence in one blockbuster, game-changing innovation. It reflects so many of the things that our contemporary world is good at - indeed, great at.

Changing age old patriarchal mindsets is a difficult long process and involves constant communication and dialogue.

Unfortunately, changing forms of Internet communication are quickly outpacing laws and technology designed to allow for the lawful intercept of communication content.

We're moving into an era when things are dematerialised and much more holographic. Floating above the physical world and the geographic map, there's another landscape that's constantly changing - something like a cloud - of communication, information, exchange and commerce.

The way communication works is changing.

I didn't have a lot of communication with Elvis. You had to go through a barricade to get to Elvis. It was people hanging on every word, and I felt very uncomfortable a lot of times.
