The device on its own probably won't lead to lasting results
Aspire's President and CEO, Kathy Crothall, PhD, says that while a person with the device can technically eat what they want, there's really more to the story. "There are no specific food restrictions," she explains. "However, in lifestyle therapy, which is given in conjunction with this therapy, patients are taught portion control, making wise food choices, understanding their triggers for overeating, strategies to avoid overeating, reading food labels, etc."
Crothall goes on to note that the only way the device can successfully work is for the patient to chew food very carefully and thoroughly, which makes logical sense, since you physically can't suck out a big hunk of chicken nugget through a tiny tube. She says this helps with portion control and mindful eating, because patients must slow down and become more aware of what they're consuming. Also, you have to drink a load of water, which also helps your gut feel full. Thanks, water.
The device is removable, but patients have to work carefully with their doctors to determine when that happens, and they're often advised to go longer between aspirations to see if they start gaining weight again. Basically, you have to find out if you've successfully changed the habits that got you to needing the thing in the first place.
