By Dr. Madelyn Fernstrom College credit for walking? That’s what the University of Georgia offers as one of its fitness classes for students. Whether this is a good sign or bad sign for our nation’s fitness is debatable.  Most of us are very familiar with the public health message about the multiple benefits of walking. A daily 20- to 30-minute walk supports cardiovascular health, weight control, and stress management. But how many of us actually follow that advice? The results might surprise you. Nearly 40% of Americans report that they “do not exercise.” This percentage has remained stable for many years. National recommendations for daily physical activity are actually quite modest: a minimum of 150 minutes of moderate activity per week. This translates to about a half hour of brisk walking five days a week. Some recent evidence using more sophisticated activity sensors (instead of self-report information) suggests that only around 4% of adults meet that goal. Why is it such a chall

By Dr. Madelyn Fernstrom With the holiday season adding extra activities to our already busy lives, we all sometimes feel we’re running low on energy. And this lack of energy can become a barrier to enjoyment. Below are three of my favorite strategies for boosting holiday energy in a healthy way.  I hope they’ll also work for you! Structure Your Eating.   Make sure to pre-plan your eating day; avoid skipping meals. No time for lunch? Try a protein bar or shake along with fruit if you’re on the run. Carry a small bag of nuts and/or dried fruit with you for a quick emergency energy boost, especially in the late afternoon. When you avoid getting “over-hungry” it’s much easier to resist the holiday treats on every desk and in office break rooms!  Don’t Skimp on Sleep. While it might be tempting to cut back on your sleep to lengthen your active day, fight that urge. Aim for at least seven hours nightly during this busy season. When you’re rested, you’ll be much more efficient with your time

By Dr. Madelyn Fernstrom There’s a lot of debate about whether high-calorie “junk” foods should be taxed to help stem the obesity epidemic in our country. Maybe we can gain some insights from the recent policy change in Denmark. About a year ago, Danish lawmakers instituted a fat tax — a surcharge of foods high in artery-clogging saturated fat. The Danish tax ministry has now repealed that decision, citing a negative effect on both businesses and consumer buying power. So what went wrong? Perhaps one problem was taxing a whole category of nutrients (fat) rather than specific foods. The bigger problem seems to be that consumers just bought these foods elsewhere. They went to neighboring countries where prices were lower to buy their favorite butters and ice creams. Most of us are familiar with the “soda tax” issue in our country. Most recently, a bill that would have imposed taxes on sugary drinks was defeated in California.  The Danish legislature has now cancelled plans for a tax on s

By Dr. Madelyn Fernstrom Grapefruits are one of nature’s perfect fruits – low in sugar, rich in fiber, and a great source of vitamin C. But this fruit also contains a compound that can interfere with the activity of some prescription medications. A new study published this week in the Canadian Medical Association Journal reveals that the number of these drugs has significantly increased over the past few years. Researchers estimate that there are 43 drugs (26 having been introduced to the market in the past 4 years) that have been shown to cause serious harm in susceptible individuals when mixed with grapefruit. There are three major categories of drugs that can have serious negative effects when combined with grapefruit: - Cholesterol lowering statins - Some heart drugs, like beta-blockers - Some antibiotics While food and drug interactions are printed on every label and stated on package inserts, many people do not take these warnings seriously.  The best step is to talk with your do

By Dr. Madelyn Fernstrom PepsiCo has just launched a new soda in Japan, claiming to burn fat and support weight loss. It’s called “Pepsi Special” and the “special weight loss ingredient” is the addition of dextrin to the standard Pepsi formula. Dextrin is a non-digestible fiber, used in baked goods and other food products. Scientific studies have documented that fiber can help bind small amounts of dietary fat, and this metabolic observation is the sole “science” upon which this claim is based. Americans have a love-hate relationship with soda, and soda consumers are always happy to hear of some redeeming health benefit that helps justify consumption. This is not the first time soda has made a weight loss claim. In the U.S., you might be familiar with a soda named “Celcius” containing 200 mg of caffeine (the amount in a large mug of coffee) claiming to burn fat and raise metabolism. And Coca Cola’s Fuze Slenderize energy drink, containing a special blend of minerals, promises to help

By Dr. Madelyn Fernstrom You might be surprised to hear that the day after Thanksgiving can be a big barrier for many people when it comes to sticking with a healthy lifestyle over the holidays. This is the day most people make the decision to indulge smartly and adjust their eating and activity patterns to adapt to the culinary treats of the season, or disconnect from mindful eating until January and “worry about it later.” The first step in this decision starts with what I call “eater’s remorse” – feeling bad about your overindulgences of the previous day. It’s easy to get stuck in the mindset that you’ve gotten off track, and there’s no hope for your diet, so why not just keep eating until New Year’s Day.  Today is the day to adjust your thinking for weight control success. No more guilt!  Thanksgiving is just one day of eating, even if you’ve eaten way more than you intended. Don’t feel guilty about your past eating. Learn from your eating behavior, to see how you can take better
