How many calories are in a pound? This seemingly simple question stumped me on my family medicine board recertification exam seven years ago — twice. (I think they asked the question in two different ways. I hoped they were experimental questions that didn’t count.) Later that day, I found the answer: 3,500 calories equals one pound. I don’t remember which multiple-choice answer I chose, but I do remember choosing the same answer ...

Several years ago, I was meeting a young woman in my clinic for the first time. She was healthy but had been obese most of her adult life, even though she had tried many methods of losing weight. We spoke for a few minutes about diet and exercise, and she agreed to see the nutritionist. A few months later, she came back to check her progress. She had lost weight, about ...

A patient of mine brought donuts in yesterday for the staff, and I confess! I had the one with sprinkles. But with the study published in JAMA reporting that 35 percent of U.S. men and 40 percent of U.S. women are obese, I felt the need to talk a little about obesity and reproduction. The endocrine system is tightly regulated by hormones which provide feedback to the brain to control their ...

I am about to place my plate in the sink, until I see a single pea left on my plate. I recall a recent article in National Geographic that stated that one-third of all the food we produce is wasted. I have a Zen moment, and think of the journey the pea made to reach my plate. A farmer in California sowed the seeds six months earlier. A farm worker harvested ...

No matter how early I rise with the intention of getting my workout done before my children wake up, I’m rarely able to do it alone. Most days my 3-year-old daughter climbs out of bed and comes straight down to our home gym and watches me do my workout. Often times she’ll sit quietly in the corner, but sometimes she’ll join in and follow the trainer on my workout DVD and ...

It’s hard to eat less when there is too much on your plate. That’s the major reason why America is in the throes of an obesity epidemic, abetted by the aggressive marketing of all things edible. More esoteric-sounding reasons for this epidemic -- such as fat-favoring microbes in your body or hormone-laden foods -- shouldn’t even be part of the discussion, because how much we consume largely explains why we’ve put on ...

Medical literature is full of studies showing that most diets don’t encourage long-term weight loss. In fact, the majority of diets lead to weight gain. Most people end up gaining back the few pounds they’ve lost within a year of dieting -- plus a few extra pounds on top of that. There are many theories for why this happens. An article from the New England Journal of ...
