Bariatric weight loss surgeries, such as gastric bypass, sleeve gastrectomy or laparoscopic adjustable gastric banding (LAGB), force patients to drastically reduce the amount of food they consume by surgically creating a small stomach pouch. Most gastric procedures reduce the stomach's holding capacity from about two quarts to two ounces. When eating, this pouch fills quickly. Because patients feel satisfied and full sooner, they eat less.
I have helped numerous clients succeed in significant weight loss journeys that involve losses of over 20-30 kg in body fat over the space of 1-2 years or more. I actually find such longer term journeys more rewarding as they allow me to teach my clients about the impact of nutrition and lifestyle habits on their physiology. This not only helps them, but also helps those closest to them as well.
