  • Why labelling is important

    Ever noticed that restaurants don't post nutritional information?  Some do, but by and large, they don't.  Well, a recent American Journal of Public Health study shows how far off we can be in estimating the calorie and fat content of common restaurant choices.  And, sadly, the less "healthy" the choice, the greater we underestimate calorie and fat content.
     
    Approximately 200 individuals (80% college graduates) who ate out at restaurants (14 meals eaten out in past month) were asked about the nutritional content of common food items encountered in restaurants (keep in mind average daily nutritional intake should for most of us be at 2000 calories and no more than 65 grams of fat - lower is better).
     
                                            Consumer estimate                             Actual
     
    Hamburger and fries            777 calories, 37 grams fat                   1240 calories, 67grams fat
    Chef salad                          452 calories, 21 grams fat                   930 calories, 71 grams fat
    Fettuccine alfredo                704 calories, 31 grams fat                  1500 calories, 91 grams fat
    Cheese fries with ranch        869 calories, 40 grams fat                  3,010 calories, 217 grams fat
     
    I included the last option from the study due to football season!  In general, consumers estimates were HALF the calorie and fat content.  No wonder why restaurants aren't keen on labeling food content or portions the way the FDA requires food in our grocery stores. 
     
    Ironically, consumers estimated more-healthful items (turkey sandwich, chicken) much more accurately - so its not as if they don't at some level, "know" the difference.
     
    Bottom line - enjoy "eating out" but generally speaking, doing so less often, asking about nutritional info if not posted, and becoming more informed will prevent adding the usual 1-2 pounds per year!

  • Four ten minute walks a day!

    "Pre" high blood pressure is defined as 120-139 systolic (the "top number") over 80-89 diastolic (the "bottom number").  Pre hypertension leads to . . well, high blood pressure (greater than 140 over 90) unless we do something about it.
     
    A new study demonstrates that ONLY 4 ten minute walks a day reduces blood pressure . . and the effect lasts even longer (11 hours) than a 1 forty minute walk (which lasts 7 hours)!
     
    How's that for easy?
     
    Coupled with the eating more fruit (more potassium in ALL fruits lowers blood pressure), eating healthier snacks (with less salt/sodium which raises blood pressure), relieving stress, exercising or just breathing outdoors (which lower blood pressure) . . and eating right (on the road to weight loss).
     
    You see . . little choices all add up in a BIG way!
     
    Have a great day.

  • Taking the Fitness Plunge - Confessions of a Couch Potato

    I have struggled with my weight since grade school and a big part of my weight problem over the years has been due to lack of exercise. My fitness level has ranged from sub-zero to fast-paced walking 45 minutes 4-5x/week at my best.  Exercise has always been something I’ve had to make myself do. I don't like to sweat, fell asleep during yoga, don't have a bike, don't enjoy exercise in any form whatsoever. It’s not a matter of finding the time or having the resources to exercise- I just don’t like it.  I am a complete and utter couch potato by nature.
         
    Of course working at Lumenos, we are constantly made aware of our healthy (or in my case, not so healthy) habits thanks to all the programs offered, the information and supportive encouragement we receive.  Even working in such a healthy environment, it's one thing to believe it's a good idea to live a healthy lifestyle and a whole other thing to actually do it! So last summer, I joined Weight Watchers (again) and got back on the wagon, so to speak. I did all right during the first 12 weeks food-wise, but I didn't increase my exercise and continued being a couch potato. I was walking some but not very much.  After all, it was hot outside.

    I tried to stay on the Weight Watchers program for another 6 months and was able to maintain my losses over the winter but was struggling to keep going. After losing the first 25 pounds I hit a plateau, so I decided I had to take the exercise plunge to be successful, and thought I would share my experience with the other couch potatoes out there.

    Here were my criteria for starting an exercise program:

    1. Climate controlled environment
    2. 30 minutes or less
    3. Painless
    4. Convenient
    5. No barbells, mirrors or skinny people in spandex

    I debated purchasing home gym equipment but knew deep down I wouldn’t do it.  I'm the type where the treadmill would become a clothes rack. So I settled on the easiest, friendliest, most foolproof environment I could find- a Curves establishment. I pass this particular Curves every night on my way home from work, and frequently shop at the grocery store sharing the same parking lot, so its presence alone was constantly making me feel guilty. Frustrated with my lack of further progress, I decided to give it a real try for 12 weeks and see what happened.

    In those 12 weeks, I have not only seen even more weight loss, but I've lost 10 inches overall since my first measurement. The exercise has really fueled my weight loss, my level of energy, attitude, motivation to keep going, lots of positive things. I still don't love it, but it's something I can do 3-4x/week and it's not too awful. How’s that for a new attitude?

    If I can get up off the couch, anybody can.  I would encourage other couch potatoes out there to try to find something active you can do that fits your needs and schedule.  Start off slow with an easy program that’s not overwhelming.  Curves isn’t for everyone, but I now believe there is something out there for everybody- if you look.

    If you are trying to lose weight the exercise really makes a difference. It's really hard just to limit your food and continue to lose- like driving a car with no gas in it.  I think a lot of people give up when they only change their diet and don’t see enough results or hit a plateau like I did. Even if you’re not overweight, exercise is good!  You're never too old, too fat, or too out of shape to start.

    Anybody else struggling to get active?

    Any former couch potatoes care to comment? How did you find the right fitness environment for you? What did it take to make the change from non-active to active?

  • It's official - Turn off the tube and computer

    Sometimes research validates plain old common sense.  This one I had to mention.
     
    The average American watches 4 hours of television per day . . not to mention the additional hours we increasingly spend in front of our computers.
     
    This month's American Journal of Public Health reports a study on about 1000 Boston low income residents who watched 3.6 hours of TV daily.  The intent of the study was to determine how the amount of TV viewing impacted the average number of steps taken per day.  Incredibly, no one had ever really studied the direct correlation between TV watching and pedometer readings.
     
    For each hour of TV viewing, 144 fewer steps were taken each day - or, for the average person watching 3-4 hours of TV, a total of 520 fewer steps per day.  For the average individual, they were nearly 50% less likely to get 10,000 steps per day.  And this study doesn't include the several hours per day of personal (home) computer use that has also been documented in other studies.
     
    So. . . put down the remote (AFTER turning the TV and/or computer off) . . walk out the door and get moving!
     
    Have a great weekend.
