Lose weight without worrying about food? Imagine this?!
Via Popular Science "Safe and effective weight loss doesn't yet come in a pill, but maybe one day it will. A new study has found a chemical that keeps mice from gaining weight through overeating. The drug also seemed to protect lab mice from some of the harmful effects of obesity: When researchers measured the mice's blood, they found reduced levels of insulin, cholesterol, and other molecules, compared to obese mice who didn't get the drug."
“This pill is like an imaginary meal,” says Ronald Evans, director of Salk’s Gene Expression Laboratoryand senior author of the new paper, published January 5, 2014 in Nature Medicine. “It sends out the same signals that normally happen when you eat a lot of food, so the body starts clearing out space to store it. But there are no calories and no change in appetite.”
In the United States, more than a third of adults are obese and 29.1 million people have diabetes, according to the Centers for Disease Control and Prevention. Both obesity and diabetes lead to an increase in health spending, a greater risk of health complications and a shorter lifespan.
Did your nutritionist give YOU guidance in regards to carbohydrate intake after your roux en y gastric bypass surgery?
Background: Exact carbohydrate levels needed for the bariatric patient population have not yet been defined. The aim of this study was to correlate carbohydrate intake to percent excess weight loss for the bariatric patient population based on a cross-sectional study. The author also aimed to review the related literature.
Materials and Methods: A cross-sectional study was conducted, along with a review of the literature, about patients who underwent Roux-en-Y gastric bypass at least 1 year previously. Patients had their percentage of excess weight loss calculated and energy intake was examined based on data collected with a four-day food recall. Patients were divided into two groups: 1) patients who consumed 130g/day or more of carbohydrates and 2) patients who consumed less than 130g/day of carbohydrates.
Limitations: The literature review was limited to papers published since 1993.
Results: Patients who consumed 130g/day or more of carbohydrates presented a lower percent excess weight loss than the other group (p= 0.038). In the review of the literature, the author found that six months after surgery patients can ingest about 850kcal/day of carbohydrates, 30 percent being ingested as lipids. A protein diet with at least 60g/day is needed. On this basis, patients should consume about 90g/day of carbohydrates. After the first postoperative year, energy intake is about 1,300kcal/day and protein consumption should be increased. We can, therefore, establish nearly 130g/day of carbohydrates (40% of their energy intake)
Conclusions: Based on these studies, the author recommends that 90g/day is adequate for patients who are six months post Roux-en-Y gastric bypass and less than 130g/day is adequate for patients who are one year or more post surgery.
The author concludes that maintaining carbohydrate consumption to moderate quantities and adequate protein intake seems to be fundamental to ensure the benefits from bariatric surgery.
