Here’s an excerpt from an article entitled, “5 Key Ways to Lose Weight After 50” by Hallie Levine, AARP, May 9, 2018, https://bit.ly/2ulWANV:
Try occasional fasting
We’re not talking juice cleanses. Rather, research now shows that a specific type of intermittent fasting, known as fasting-mimicking, can trigger weight loss as well as improve your overall health. People who followed this type of diet plan — where they consumed only 750 to 1,000 calories five days out of each month but otherwise ate normally — lost, on average, six pounds, shed one to two inches of their waistline, and saw both their blood pressure and levels of IGF-1 (a substance linked to increased cancer risk) drop significantly, according to a University of Southern California study published last year.
How might it work? “When you gain weight, the nerves in your hypothalamus that conduct signals from your fat cells to the rest of your brain become damaged,” says Louis Aronne, M.D., director of the Center for Weight Management and Metabolic Clinical Research at Weill Cornell Medical College. “As a result, your brain doesn’t realize that you’re full, so it keeps signaling you to eat.”
But when you take a day to not eat very much, he says, “you’re reducing stress on your hypothalamic nerves, so it gives them time to recuperate.” That day of rest for your nerves could be especially important for older people, he says, because of the damage that oxidative stress can further do to your weight-regulating system.
As for how to start, “I tell patients who want to try it to eat only about 800 calories twice a week, focusing mainly on vegetables, protein and healthy oils such as olive oil,” he says.
To help yourself feel fuller longer on days you’re not fasting, Aronne recommends following a low-carb diet in which about 30 percent of your calories come from protein and the rest from nonstarchy veggies, nuts and beans. Craving bread? “I tell patients that the best time to eat these types of starchy carbohydrates is at the very end of the meal, after they’ve had their veggies and protein,” he says. Aronne’s research shows that people who eat this way not only have lower levels of blood sugar and insulin after eating but also have bigger boosts in hormones like GLP 1, which help keep you feeling fuller for longer.
