Slimming effects of alli may trigger many unpleasant side effects
This no-win choice is coming soon to a drugstore near you.
A year ago, I wrote about the U.S. Food and Drug Administration's consideration of over-the-counter sales for the fat-blocking drug, orlistat. It now has the FDA's blessing: Expect to see it on store shelves this summer under the name alli (pronounced "ally").
This is no magic pill, and it isn't going to work if you live on deep-fried candy bars and consider lifting the remote vigorous exercise. alli might help you shed some extra pounds - if you work out and eat a low-cal, low-fat diet along with it.
But if you're doing that, why take a pill?
Its maker, GlaxoSmithKline, says that alli might help people lose 50 percent more than they would with dieting: that means 3 pounds instead of 2, 7.5 pounds instead of 5, 15 pounds instead of 10. No guarantees, of course.
The drug works by blocking digestion of 25 percent of the fat in your food, about 150 to 200 calories a day. Over six months, people who tested the OTC version lost 4 to 6 pounds more than those who took a placebo.
Still planning to pick up a case or two? Don't forget the adult diapers.
Sad to say, but that lost poundage comes at a price, and I'm not just talking about the $1 to $2 a day it's going to cost. The drug company refers to them as "treatment effects," which is its tidy euphemism for bowels gone wild and toxic undies.
Remember, orlistat works by blocking absorption of fat. And it's gotta come out somewhere.
What the experts are saying
• Dr. David Katz, director of the Yale Prevention Research Center, commenting on the possibility of abuse of alli by the eating-disordered:
"Anal leakage is not likely to be too socially acceptable among image-conscious teens - or anyone else, for that matter."
• Dr. Alastair Wood, FDA panel chairman, to company executives during hearings on its proposed OTC status:
"Have you considered placing a warning on the box, 'Don't take this product while wearing your new La Perla underwear'?"
What is this stuff?
Here's the skinny on the fat-blocker alli (pronounced "ally")
• What: Over-the-counter version of the prescription drug Xenical (orlistat), one of a new class of anti-obesity drugs known as lipase inhibitors and the only FDA-approved weight-loss treatment.
• Who it's for: Overweight adults following an exercise program and a reduced-calorie diet with no more than 30 percent of calories from fat, preferably closer to 15 percent
• Who it's NOT for: Anyone under 18; anyone with a body-mass index less than 27 to 30; people who already have trouble absorbing food; organ transplant recipients; people on blood-thinning drugs; diabetics or people with thyroid disease
• What it does: Prevents enzymes in the gastrointestinal tract from breaking down dietary fats into smaller molecules, decreasing fat absorption by 25 to 30 percent
• Pros: Effects limited to the digestive tract. In studies, weight loss was 4 to 6 pounds more than with a placebo over six months.
• Cons: Effects can include gas with oily discharge, diarrhea, bowel urgency and anal leakage. Study participants who stopped using the drug regained all lost weight. Calorie-counting still required.
How much fat?
• To help avoid icky side effects, the drug maker recommends that alli be taken with a low-calorie, low-fat diet - ideally 15 percent of daily calories. To put that into perspective, let's say your diet plan allows 1,600 calories a day; 15 percent is 240 calories. Divide that by 9 - the number of calories in a gram of fat - and you're allowed 26.4 grams of fat per day.
Is alli your ally?
Here's GlaxoSmithKline's "alli weight-loss readiness quiz." The company estimates at least 5 million Americans a year will use alli.
• I am willing to do the hard work to lose weight gradually.
• I am committed to following a reduced-calorie, low-fat diet (an average of 15 grams of fat per meal).
• I understand that if I take alli with a meal containing too much fat, I may get bowel changes known as treatment effects.
• I am committed to eating smaller portions.
• I am committed to making time to be more physically active.
• I will read and follow the alli label.Source: Myalli.Com
alli facts
60mg dosage in each alli pill, half the strength of the prescription version Xenical.
• A, D, E & K: Water soluble vitamins whose absorption is blocked by the drug - so you need to take a multivitamin pill as well.
• The less fat you eat - say, 15 percent of total calories - the less severe the side effects, which might subside after a month or two or last much longer.
• GlaxoSmithKline already has a Web site up for future alli users (myalli.com) that will offer support and guidance, including a customized online action plan, menus and shopping lists, lessons about meal planning, managing hunger, dealing with setbacks and a way to chat with other alli users.
More expert opinions:
• Dr. Jim Hill, director of the Center for Human Nutrition at the University of Colorado Health Sciences Center:
"The bottom line is, look at what's out there for weight loss - there are some really, really scary products. This one is not very scary."
• Dr. Sidney Wolfe, director of Public Citizen's Health Research Group, in a petition last April asking the FDA to ban orlistat:
"This drug causes a significant increase in the incidence of aberrant crypt foci, which are widely believed to be a precursor of colon cancer. The failure to ban the prescription version - or worse, to make it much more widely available by allowing OTC sales - is a decision that is likely to increase cancer incidence. Orlistat is a drug that has shown minimal efficacy coupled with both known and potentially important serious adverse events."
• Suzanne Farrell, spokeswoman for the American Dietetic Association and owner of Cherry Creek Nutrition:
"As a dietitian, I'm concerned about over-the-counter use, since diet instruction from a health professional wouldn't be something that came with it."
Comments from diet-blog.com:
• "I took this for one day. That was more than enough for me. I decided that I would rather deal with the indignity of being overweight than the indignity of soiling myself. Whoever came up with this drug hates overweight people and wants to punish them."
Carla
• "I am 5 feet 4 inches and weigh 115. (Orlistat) is great for me, and it has worked for years with very few side effects. Really. It should be something that we all use."
April
• "I was on it when I was around (198 pounds), and I got down to (130 pounds). Without the (orlistat), I was more likely to eat bad foods because there was nothing to stop me. Now I am less likely to because I don't want to spend all day on the toilet."

The company says
• Steven L. Burton, vice president, Weight Control, GlaxoSmithKline Consumer Healthcare, announcing alli's OTC approval earlier this month:
"With alli, we're excited to offer a revolutionary approach to weight loss. alli is more than a pill - it's a comprehensive program that works in conjunction with a sensible diet to increase weight loss. Because weight loss doesn't happen overnight, we're starting to educate consumers now about the importance of realistic expectations, gradual weight loss and lifestyle changes."
