Wednesday Bubble: long-term effects of the short-term binge
Stress, emotions, life. All of these factors can contribute to binge eating. However, have you ever wondered if the binges that might occur during long vacations or breaks may contribute to a longer-term problem?
This week, I’m bursting the myth that many of us, including myself, like to tell ourselves after a few weeks of the ‘bad food’ binge, “it won’t hurt.”
Guess what?
This bit of information is straight out of BioMed Central‘s nutrition and metabolism section, and it ain’t pretty. However, the good news is that after reading this, lengthy binges may become a thing of your past and hopefully, not your future.
Researchers are saying that individuals who lead a fairly sedentary lifestyle and consume large amounts of energy (not nutrient) dense food over a period of as little as four weeks may end up with more fat mass over the long-term, even if they lose the weight they’ve gained from binging by returning to usual eating and activity levels.
In this particular case, 18 young men and women (aged ~26 years) who weighed within the normal healthy ranges were asked to increase their daily energy intake by 70% (including at least two fast food meals per day or foods rich in protein and saturated animal fat) over four weeks and limit physical activity to no more than 5,000 steps a day (which they measured using a pedometer). Thereafter, they could return to normal. The findings?
Compared to a group of men and women who ate and exercised normally, a month of binging led to an average weight gain of 14 pounds! Moreover, only a third of the people studied returned to their normal weigh after 6 months, and on average, they still managed to gain an extra 3 pounds by one year’s time following the study. Even worse was the fact that fat mass increased by as much as 3% of the total body weight by the end of the study. When the researchers looked at this separately, they found an average increase in abdominal/trunk fat by ~17% and leg fat mass by 28%.
The underlying message is that a short-term excessive binge can possibly change your physiology, making it harder to lose the weight and keep it off.
Granted, this is a small study and was conducted in individuals substantially younger than the readers of this blog. Nevertheless, if the findings prove true, it is likely that the longer term ramifications of binging at our age may pose some serious effects on health.
Just a wee bit of food for thought for a Wednesday. Keep it healthy. And move your body.
Read MoreIs black cohosh a flash in the pan?
I am a true believer of black cohosh, that wonderful herb that for many women, simply stops hot flashes in their tracks. The clinical evidence in support of the effect of black cohosh on symptoms has also been pretty positive, except when it comes to bone health. Admittedly, I’m a bit in the dark on this one because I had never read anything associating the two…until now.
To examine the effect of black cohosh on bone density, researchers randomly assigned 128 postmenopausal to one of three regimens:
1) Six weeks of highly intensive exercise directed towards protecting bone mass (e.g., strength training, aerobic activity) interspersed with 10 weeks of moderate intensity exercise (e.g. brisk walking)
2) The above program plus 40 mg/day black cohosh
3) Wellness program (light exercise for one hour a week, such as stretching, walking, balance)
Although exercise had a definite and positive effect on bone mineral density, taking black cohosh provided no additional benefit. However, women who were assigned to wellness only did experience a minor decrease in the bone density in their spine compared with women who exercised. Other variables, including lean body mass, heart disease risk and menopausal symptoms, were also favourably impacted by physical activity but again, not by the addition of black cohosh. The study was published in the online edition of Menopause.
Clearly, when it comes to bone density, exercise is the winner. Black cohosh does not appear to add any additional benefits, although it may ultimately prove to enhance any positive effects on menopausal symptoms, especially since previous clinical trials have been favourably in this regard.
Time will only tell. In the interim, keep moving and don’t rely on black cohosh to preserve your bone health.
As always, Reuters Health has done great reporting on this same study. I encourage you to check it out!
Read MoreJust an hour a day keeps the weight away
Yikes! Seems like every time you turn around, there’s another study upping the ante on exercise. Last year, I wrote about 2005 USDA guidelines suggesting that adults need about 60 to 90 minutes of moderate physical activity a day for health and weight maintenance, i.e. at least 60 minutes of moderate to vigorous exercise daily to stave off gradual, unhealthy body weight combined 30 minutes daily can help prevent chronic diseases. To achieve optimal physical fitness, the recommendations suggested the incorporation of cardiovascular conditioning, weight training, and resistance exercise to improve strength and endurance. Conversely, 2008 Federal Guidelines suggested that adults needed about 150 minutes per week of moderate intensity exercise to maintain health, while the Institute of Medicine suggested 60 minutes a day to prevent weight gain. Confused yet?
Researchers followed a group of over 34,000 women (mean age ~54) for 13 years, examining their amount and type of weekly physical activity (e.g. high versus low intensity), body weight, height, menopausal status, use of hormones or not, chronic disease, alcohol use, smoking and diet. (If you’re wondering, high intensity refers to running. bicycling, aerobic exercise or dance or use of aerobic machines, while low intensity refers to yoga, stretching, tennis, squash or racquetball, and lap swimming.)
Overall, study findings showed that on n average and regardless of physical activity level, women gained almost 6 pounds over the course of the study. However, women who exercised anywhere from 2.5 hours to less than 7 hours a week gained significantly more weight then women who exercised at least 7 hours a week (or one hour a day). In fact, women who exercised less than an hour a day were significantly more likely to gain at least 5 pounds over the first three years of the study. Note that these results apply only to normal weight women (body mass index <25).
I’ve recently increased my level of physical activity to an hour a day, not because of these study results but because I’ve been unhappy about the hormonally-driven tire that’s starting to appear around my midsection. I must tell you; it’s a huge time commitment. Undoubtedly, if you are busy in your career or with your children, finding an hour a day to exercise can be difficult. What remains unclear is whether or not this hour can be divided into increments.
What do you think? Do you have the time? Are you motivated? Or does this information discourage you?
Read MoreStirring the pot: a conversation with author/chef Mollie Katzen on food, women and aging
Just about anyone who’s interested in cooking and whose formative years took place in the late 60s and 70s knows these names: Moosewood Cookbook and The Enchanted Broccoli Forest by Mollie Katzen. Personally, both of these volumes occupied prominent places on my bookshelves for years. That is, until worn from overuse and stained with food and memories, I reluctantly let them go.
So, what do cooking and midlife and menopause have to do with each other? And what type of insights can chef and author Mollie Katzen lend to the conversation?
I originally approached Mollie in search of nutrition advice for women going through midlife and menopause. Although I realize that she isn’t a dietician or a nutritionist, as someone who’s immersed herself in food for decades, she seemed quite capable to lend a perspective. But as our conversation took hold and we found our rhythm, I realized that the focus had shifted: what I ended up with was a mini-instruction manual, not only for eating healthy but also for forming and maintaining positive relationships with food and with ourselves.
A champion of “keep it healthy,” Mollie entered the scene when cookbooks were largely geared towards the typical American meat and potato diet. When the Moosewood Cookbook first hit the shelves, “there was barely even a cookbook section in the bookstore, let alone, a ‘healthy eating’ or ‘vegetarian’ section,” explains Mollie. Yet, she is not what many of us classify as “vegetarian,” and although she primarily skews the dinner plate towards greens and veggies, she consistently includes small amounts of animal protein. “My diet in my 30s and 40s could have been classified as practically vegan,” she says, “even if I wasn’t orthodox about it.” (At that time, she was also keen on a low-fat diet, which, coupled with the lack of ample amounts of protein, spelled trouble.) “It was almost ‘remorse cuisine;’ I’d eat this way and by mid-afternoon I’d almost be fainting, depleted, irritable. I had no focus. I found that I wasn’t functioning and would wonder what was wrong with me because I thought I was eating the purest diet on the planet. I felt like I was falling apart.”
If you are familiar with the earlier editions of Mollie’s books, they concentrate heavily on whole grains and legumes. However, age has paved a path for a significant alteration in what she eats. Emphasizing that the amount of bulgar and beans she’d have to eat to obtain the amount of protein that she needs for her blood sugar to stay stable could easily translate into an extra 50 pounds, Mollie says that she has changed her diet to include grass-fed animal protein and raw milk cheese, milk and butter.
What about aging and diet? “I think that women get really frustrated,” she says, pointing out that as we age, even if we change nothing about our lifestyles, e.g., if our lifestyle is reasonable, we are of fairly normal weight, exercise moderately and eat pretty well, we still gain weight. “Our bodies become an inefficient machine and our metabolisms slow,” she says, adding that one of the most consistent things she’s observed amongst her friends is the “oh my god, what happened to my body” moment. The ‘I’m minding my business, doing the same things I’ve always done and all of a sudden, I’ve got this spare tire, I’ve got the fat” epiphany. Sound familiar?!
Although challenging, the answer to this common dilemma is fairly intuitive. And while we’d love to fool ourselves into believing that declining hormones are the primary culprits, they aren’t. Rather a decline in physical activity and lack of dietary restraint are the key players. Mollie agrees that while women can’t do a whole lot about the fat redistribution, the “one thing [they] need in order to keep the [weight gain] at bay is to keep muscles toned as possible with resistance exercise and also, eat less.” New flash! This actually works; Mollie reports that she currently weighs the same as she did in her 20’s!
Of course, what works for one woman might not be exactly what works for another. We all need to forge our dietary paths and strategies that work for both our individual metabolism and our bodies.
“Health is trial and error,” Mollie explains. “So much of it shows up in how you feel a few hours later. For example, do you feel sleepy after you’ve eaten? Do you feel sluggish or irritable later in the day? Do you have trouble sleeping at night? For me, these were all symptoms of what was going on when I was eating almost no fat or protein.” Much in line with health and nutrition experts, Molllie’s strategy has been to reduce her daily caloric intake while at the same time increasing the percent of calories in her diet that are fat. “I get a good 30% of my calories from nuts, olive oil, avocado and fatty fish.” And when she snacks, its the good fats that she reaches for: “avocados and nuts, especially walnuts. When I am hungry, I have a handful of almonds. I just think that for people as they get older, they should lose the pretzels and eat almonds or guacamole or something with good fat in it.”
We also need to slow down. Bet you’ve heard that before! Mollie says that the most radical transformation we can make with food isn’t so much changing what we eat but how we eat it. Her advice? “Don’t even pick up the fork for the first minute that the food is served. Breathe deeply, look at it, admire it, thank the cook, be grateful. Then pick up your fork, take a few bites and put your fork down. Swallow your food. Women simply don’t have the metabolic ability to do a good job with all that food.”
Food heals. As women, our love-hate relationship with food is complex. We not only use food as fuel, but also to feed our emotions. Or on the flipside, we deprive ourselves in ways that are counterintuitive and sometimes, downright unhealthy.
“This sounds so obvious,” says Mollie, “but I really want people to turn towards cooking and not away from it. To me, the more hands-on and proactive we are about food and cooking, the more we heal whatever issues or concepts we have around food. I’ve actually seen people healing their relationship with food by diving into it.” Make food one of your favorite hobbies. She suggests that rather instead of shunning away from the grocery store run, step back and make it a trip to pick up something beautiful to be celebrated. “Diving into a more positive, deliberate relationship with food gives you something nice to do,” she adds.
What are the take-away messages?
- Tailor it uniquely: keep it healthy.. for you.
- Move towards healthier choices and use food in a healing, more positive manner.
- Embrace yourself with beautiful food, whether it’s a perfect tomato from the Farmer’s Market or some kick-ass, green-as-grass guacamole.
- Take it slow, and breathe.
Wise words, from a wise woman who knows her way around a kitchen or two.

Read MorePreventing heart disease in menopause. It’s as simple as L-D-L
Aging. It’s associated with all sorts of diseases. In women in particular, heart disease is a big red flag since there is a lot of evidence showing that after age 40, risk for developing heart disease rises and continues to rise.
So, is increased risk due to to aging in general or to menopause in particular? Moreover, is there anything you can do now to reverse the trend?
Researchers have recently solved an important piece of the puzzle, discovering that significant increases in cholesterol coincide with the period right before and immediately after menopause sets in. Coincidentally, at the same time, women experience significant declines in estrogen. In this particular trial, which involved over a thousand women, researchers examined various factors that might contribute to increased heart disease risk (e.g. blood fat levels, blood sugar and blood pressure). They then compared changes in these factors over time and whether they were more in sync with aging or with ovarian changes associated with menopause.
Over the course of three to five years before menopause, a year after, and then three to five years thereafter, substantial changes were noticed in blood fats, namely low-density lipoprotein (LDL) cholesterol, which rose as average of 12 points between the first two time periods and then leveled off a few points higher (from 113 and 116, to 125 to 130. Current guidelines suggest that optimal LDL levels are below 100 and that at the very least, individuals attain LDL cholesterol levels of <130 if they have two more heart disease risk factors (and preferably, lower).
So, what are the take-away messages?
- First, declining levels of estrogen place women at risk for heart disease as they approach menopause, namely due to significant increases in LDL and total cholesterol.
- Second, women nearing menopause need to know their cholesterol numbers and insure that that becomes a priority during a normal checkup.
- Lastly, exercise and diet are key to lowering cholesterol levels, at least initially.
Both the National Lung Blood and Lung Institute and the American Heart Association recommend diets low in saturated fat, trans fat and cholesterol, and rich in whole grains, fiber, fish, lean meats and poultry. Exercise is essential, at least 30 minutes worth daily. Finally watch those risk factors and talk to your practitioner about those that may be problematic and what you can do to address them.
We may not be able to control declining estrogen but we can take positive steps to make sure that it doesn’t affect our risk for heart disease.
