What you need to know about Alli hitting shelves again

alli weight lossRemember Alli? It’s the only FDA-approved weight loss supplement, and was voluntarily recalled from the shelves last year due to tampering (AKA, there were mysteriously all sorts of different pills in their bottles). Now, Alli is back on the market, so they’ll be popping up again at your local pharmacy—and maybe even in the women’s locker room.

What should you know about this product—besides that it can’t compete with kale salads and Barry’s Bootcamp for a healthy lifestyle? We spoke to Dana James, a triple board certified nutritionist and founder of the Food Coach to find out what the heck it actually does.

“The theory is that without consuming the fat, you’re not consuming the calories or gaining the weight,” says James. One of the hitches, though, is that Alli doesn’t discriminate between the good and bad fats, so even if you eat healthfully and take it to speed up weight loss, as recommended, you’re not getting all of the benefits of a balanced diet.” Alli stops the absorption of all fats, from French fries to wild salmon,” says James.

Healthy fats are crucial to a balanced diet (doctors have been trying to explain that for years!) The good ones actually help your immune system, nerves, heart, bones, hormones, and skin.

It’s not the best long-term solution. While clinical trials involving orlistat show it can help people lose weight, the old-fashioned method might even work just as well. “While Alli might help someone who has 100 pounds to lose, in order to achieve sustainable weight loss, you need to change your behavior, and a supplement can’t help you with that,” James says.

And according to James, getting healthier should be filled with things you can stick with—like whipping up veggie smoothies, or meeting a friend for a spin class three times a week. “A supplement can’t address the emotional or behavioral aspects of eating,” says James. “It’s totally short term.” —Molly Gallagher
