My Bariatric Experience at the Scottsdale Weight Loss Center

I have been treating overweight patients all my medical career and full time over the last 3 years. I have been saying for a few years that sleep is an underrated part of weight loss. We all consider diet and exercise to be the most important. I think sleep is just as important and just last week a study was released showing the important triad of weight loss: diet, exercise and sleep.

My experience on this goes back a few years. I had a very analytical patient who worked unusual hours with very early conference calls. He kept track of the number of hours of sleep, hours of exercise and calories eaten each day. If he was doing well with all three, he was losing weight great. If he was doing any two of them, sleep and exercise but eating a little more or exercise and diet but not sleep, he maintained his weight pretty good. If he was only doing one of them, he was then gaining weight.

If you follow our blog you may recall an old posting on obesity and sleep from 2008. I just want to restate that these beliefs are still the same and more studies now prove it. We require seven hours of sleep. Several studies showed that those who slept less than 7 hrs per night were much more likely to be overweight and if you sleep as little as 5 hours, 80% of those persons are overweight.

Nick's Story

"I wish I would have come here first. We spend all our time reacting to the next great weight loss tip or program. It might work for a while, but does not last and we end up yo-yoing from one fad to the next – as we gain more weight." Read More

Everyone at the center was caring and friendly, from Bianca, at the front desk, to Lily, who is the MA.  Kristen listened to my frustrations and prior disappointments about what has not worked, and is confident that she can help me achieve my goals of weight loss.  I am looking forward and excited to see the success I will attain.

   Trustindex verifies that the original source of the review is Google. I'd lost 20 pounds on my own and struggled to keep it off.  I decided GLP-1 meds were the next step in losing more and keeping it off.  I wanted a medical doctor supervised program and chose SWLC.

I am so very glad I did!  The team in Glendale is so supportive and kind; and when I feel discouraged, they pick me up with positive energy and input.  They really do a great job with encouragement all the time.

6 weeks in I've lost 17 pounds, and am approaching weight loss with a very new perspective.  Also knowing that when I reach my target goal, they'll be there through maintenance and beyond is encouraging as well.  Good to not feel alone on this journey.
