Guest Post: Fighting Fat with Drugs – Is it Worth It?

Wednesday, July 14th, 2010

It’s no longer a trivial issue over which kids get bullied in the school playground or which adults get teased about at the office; today, obesity is an epidemic of oversized proportions. It’s a chronic disease, one that 12 million Americans are suffering from, and because of this, illness is on the rise. Diabetes, heart disease, strokes, cancer, and various other diseases are on the prowl and sending healthcare costs shooting through the roof. And while anyone with plain common sense knows that the best and safest way to fight obesity is to eat a healthy diet and get regular exercise over the course of your life, most people tend to resort to shortcuts and seek remedy in anti-obesity drugs.

To be fair, some people do need extra help since diet and exercise alone cannot do much to help them reduce because they are abnormally obese. And so weight loss pills help them control and/or suppress their appetite or prevent their bodies from digesting the fat in the food they eat. But a recent study conducted by Brazilian and Canadian researchers and published in the British Medical Journal states that even the long term use of weight loss pills contributes only to a minor reduction in weight, an average of less than 11 pounds.

And when we take into consideration the number of side effects that these pills cause – the anti-obesity drug orlistat which is supposed to boost weight loss by preventing your body from digesting fats causes digestive side effects even as it promotes only an average weight loss of 7 pounds; sibutramine and rimonabant which suppress or interrupt neural signals to disguise hunger pangs and food cravings reduce weight by an average of 9 pounds, but at the cost of insomnia, high blood pressure, an elevated pulse rate, and nausea. Rimonabant has also been known to cause anxiety and depression and other mood disorders and is as of now not approved for sale by the FDA.

On the bright side however, the drugs did serve to improve cardiovascular health and prevent and/or control diabetes, hypertension, and cholesterol, the killer diseases that attack overweight people. But then again, with most weight loss drugs being available OTC, we must ask ourselves the question – is it ok to tempt and even court the disease just because we perceive that the cure is just a pill away? And are we fooling ourselves into believing that it is ok to be overweight because anti-obesity medicines are now available even without a prescription?

The truth cannot be written more clearly on the wall – we are a nation plagued by obesity; we invite disease with open arms because of our irresponsible lifestyles, a callous attitude towards exercise, and an overindulgence of food. And because of this, our healthcare costs are spiraling out of control. It’s time we stopped depending on pills and medicines as the panacea to cure all our ills and start looking at their source instead; it’s time we bring up our children to respect and safeguard their health instead of encouraging their sedentary lifestyles and feeding them with junk food; and it’s time we started giving good health the deference it deserves – we don’t have to place it on a pedestal, it’s enough that we acknowledge its importance in our lives.

JAMA: Exercise recommendations in middle-aged women

Wednesday, March 24th, 2010

“As American women age many begin a war with their weight. A new study shows for normal weight middle aged women and older who eat a regular diet, 60 minutes of daily exercise is recommended just to maintain and not gain weight as they age. For overweight or obese women exercising 60 minutes wasnt enough to maintain and not gain weight over time.”



Eat veggies to lower your blood pressure

Monday, July 20th, 2009

I am a vegetarian.

Often people are surprised and they ask me – “How do you get your proteins (i.e. without eating meat)?”

My answer – “Vegetables also contain proteins.”

Now a new study published in Circulation compared the blood pressure between individuals who ate vegetable protein (specifically glutamic acid along with 4 other amino acids which are relatively higher in vegetable than animal protein) with people who ate non-vegetable protein (read animal meat).

They found a difference of about -2.7/-2.0 mm Hg in blood pressure in people eating more vegetables. Although that may sound small, individual results may be different (and maybe higher for you).

Obesity linked to pancreatic cancer

Wednesday, June 24th, 2009

Pancreatic cancer is the fourth leading cause of death in United States. Once diagnosed, patients have a very poor prognosis with median survival between 3 to 6 months.

A new study published in the Journal of American Medical Association has found a link between being obese in early adulthood and the risk of developing pancreatic cancer.

Individuals who were overweight (BMI of 25-29.9) from the ages of 14 to 39 years or obese (BMI > 30) from the ages of 20 to 49 years were at about twice the risk of developing pancreatic cancer (OR 1.67 & 2.58 respectively), independent of diabetes status. Also obesity at older age was associated with lower overall survival in patients with this malignancy.

The main drawback of the study is that this is a case control study, therefore the 2 factors studied (viz. pancreatic cancer and obesity) could occur together but not be causally related (although the authors did do adjust for most other risk factors of pancreatic cancer).

Food for thought: American expenditure on Food

Sunday, April 12th, 2009

“This graph shows percent of income spent on food at home and away from home in the United States since 1929. During the Great Depression, households spent a total of 15 to 20 percent of their income on food. Today, we spend about 10 percent of our income on eating at home and dining out.”

At Home and Away From Home
It is interesting to note that people are spending less on food (as a percentage of our income) although this is most likely due to rising incomes. However, there is no surprise that people have decreased the amount of money that they spend on home food while the percentage spent on eating out has remains relatively constant – which is most likely is a big contributor to obesity.
