The main guiding principles of Nutrisystem are portion control, proper nutrition and daily exercise. By relying on foods with a low glycemic index (in other words, foods that release their sugars slowly and steadily, instead of rapidly and intensely), Nutrisystem meals provide a consistent amount of energy throughout the day. The prepackaged, portion-controlled meals eliminate guesswork, while their nutritional guides encourage you to incorporate fresh produce into your meals. Nutrisystem’s meals are rich in high-quality proteins to keep you feeling fuller for longer and incorporate healthy fats (like nuts) to ensure you get all the nutrients you need. Their website allows you to track your progress and set realistic goals for yourself as well as giving you a large list of ten-minute exercises to do three times a day to help you stay active to lose weight even faster.
Rather than a long and low-intensity cardio workout, try the HIIT method of cardio: intense, fast-paced intervals that leave you completely exhausted after only a 20- to 30-minute session. This form of cardio training increases the afterburn effect, allowing your body to continue burning calories long after your workout is over. You can rotate between 30 seconds of your favorite exercises, with rest in between, as long as they work different muscle groups—such as squats, push-ups and kettlebell swings.
Support your weight loss and exercise program by getting between 1.2 and 1.6 grams of protein per kilogram (or 0.55 and 0.73 grams per pound) of your body weight, recommends research published in the American Journal of Clinical Nutrition in 2013. For a 200-pound woman, this would suggest you aim for 110 to 146 grams of protein daily, split up among three to five meals.
The key to losing weight is eating fewer calories than you expend. That creates an energy deficit, so your body taps into other sources of fuel — namely, your fat stores — to make up the difference. You’ll be able to lose weight safely by creating an energy deficit of up to 1,000 calories a day, which will allow you to lose up to two pounds per week.
"Crash diets (dramatically cutting down how much you eat) might help you to lose a few pounds at first, but they’re hard to sustain and won’t help you keep the weight off. It might seem like a quick and easy option, but eating too few calories can actually do more harm than good. If your calorie intake dips too low, your body could go into starvation mode. This will slow down your metabolism, making it harder for your body to lose weight. Make sensible, healthy changes to your lifestyle that you can stick to and avoid the fad diets."
