The Challenges of Weight Loss, Part 1
As drugs for weight loss are currently seeking approval by the FDA, one has gone the way of Fen-Phen and has been pulled off the market. The drug Meridia has been on the market since 1997 and boasted claims of at least 5 percent weight loss over placebo. However, Abbot Laboratories, the maker of the drug, voluntarily pulled the drug off the market due to clinical trials showing increased risk of heart attack and stroke.
The search continues for the “one” pill that will cause weight loss. In July the FDA disapproved Qnexa for the market, a new diet pill that combines an amphetamine and an anticonvulsant. And not just drugs, but natural products are constantly being marketed as the next “fat burner”.
The problem with developing a weight loss pill or supplement is that weight gain is multi-factorial and can be different for each person. Drug companies investigate ways to suppress the appetite, decrease gut absorption of fats, and increase metabolism as quick fixes. However, there are many other factors that cause increased weight gain. And we all know the main factor, and that is high calorie processed and restaurant food. Now that New York has passed a law to put calories next to menu items, it’s no wonder why the most recent government data reports that more than 2/3 of the American population is obese or overweight. There are often very few meals under 1000 calories, and there are many that are closer to 2000 calories! For most of us, that is considered an entire days worth of calories in one meal.
The other most common factor to weight gain is lack of activity or exercise. Walking is great exercise and perhaps one of the most common forms of exercise. However, it is not the best calorie burner. Walking for 30 minutes at a rate of 3-4 miles per hour burns about 150 calories. Walking for 1 hour at 20 minutes per mile (3 miles per hour) burns about 240 calories. One Grand Latte from Starbucks is 272 calories, and that is without any sugar, syrups, or whipped cream. Some activities burn many more calories, for example 30 minutes of cross-country skiing burns about 390 calories, 30 min of rock climbing burns 373 calories, and playing golf while walking with bag 18 holes burns almost 2,000 calories! So as Americans, we are fighting high calorie foods with not enough activity to burn these calories. Not everyone can do these activities every day, but find an activity, preferably outdoors, that you can do at least once per week, and make them different every week. The body does better with change, rather than doing the same routine all the time. Before starting any rigorous activity, please consult with your health care provider first.
In my next blog, Part 2, I will discuss other factors of weight loss when diet and exercise alone are not working.
