When I read research from the Salk Institute that revealed the benefits of intermittent fasting for weight loss, heart health, and brain health, I knew I had to give it a try. So one Tuesday last spring, I skipped breakfast. Two hours later, I started complaining. I missed food – desperately. But now, six months later, I’ve dropped seven kilos. I fast twice a week; I used to do it every workday, but began to worry I’d lose too much weight.
