“Don’t stress over joining a gym. Just walk,” advises Beth Bishop who lost 245 pounds without gastric bypass. Beth, at 380 pounds, and 5’4″, started with just a 15 minute walk. Here are some tricks that fake gastic bypass according to Jaime Ponce, MD, president of the American Society for Metabolic and Bariatic Surgery: 1) The Shrink Trick. At her heaviest, Beth consumed about 7,000 calories a day, much of it bakery products. Regular overeating stretches the stomach, making it larger. As Beth went from huge to small portions, her stomach began shrinking, and she was satisfied with less. 2) The Protein trick. Gastric bypass shuts off the part of the stomach that makes a hunger-stimulating hormone called ghrelin, says Dr. Ponce. Increasing protein supresses ghrelen, and so does cutting back on greasy foods, another strategy Beth used. 3) The schedule trick. Establishing set meal and snack times like Beth did trains your body to get hungry when you are supposed to eat. Bonus: a British study found that eating on a schedule causes hormonal changes that actually boost metabolism. 4) The Blood sugar trick. Gastric bypass changes digestion in a way that improves blood sugar quickly. Better blood sugar control leads to faster fat burning. Beth skipped the sugar-spikes. She switched to empty white stuff to natural whole grains and fruit.
