The South Beach Diet was developed by clinical cardiologist Dr. Arthur Agatston and puts some signature spin on a classic low-glycemic index diet. Developed for patients with heart health in mind, the diet seeks to eliminate spikes in blood sugar levels by removing most carbohydrates from your diet (refined flours, pasta, etc.). Once the body has eliminated spikes in blood sugar, complex carbohydrates are slowly reintroduced into your diet and you stay in this phase until you reach your target weight. By the end of the diet, you’re allowed to eat all foods in moderation—even sweets! Though this third phase of the diet recommends some precautions, they aren’t very intrusive on your everyday life.
If Nutrisystem does encourage weight loss, it may be attributable to calorie restriction and portion control, a well-supported mechanism of weight loss. A 2013 article in the New England Journal of Medicine, for example, concluded that provision of meals and meal-replacement products promote greater weight loss than "seemingly holistic" programs based on balance, variety and moderation. While Nutrisystem once touted low-GI foods as a key element of the program, the company says it no longer claims GI to be the mechanism of weight loss.
Changing the way you go about eating can make it easier to eat less without feeling deprived. It takes 15 or more minutes for your brain to get the message that you've been fed. Eating slowly will help you feel satisfied. Eating lots of vegetables and fruits can make you feel fuller. Another trick is to use smaller plates so that moderate portions do not appear too small. Changing your eating schedule, or setting one, can be helpful, especially if you tend to skip, or delay, meals and overeat later.
You don’t have to go low-carb to ditch those extra pounds around your waist in a short period of time. In fact, opting for more whole grains might just get you there faster. Researchers at Tufts University have linked eating three or more daily servings of whole grains to as much as a 10 percent reduction in visceral body fat, the kind that ups your risk for chronic diseases, like diabetes, heart disease, and high blood pressure.
"Feeling stressed can wreak havoc on our bodies. It can cause our body to produce the steroid hormone cortisol, which can make you crave sugary foods that provide instant energy and pleasure. Short-term bursts of cortisol are necessary to help us cope with immediate danger, but our body will also release this hormone if we’re feeling stressed or anxious. When our cortisol levels are high for a long amount of time, it can increase the amount of fat you hold in your belly."
