Pros: Compared to eating a traditional diet, switching to a low-carb diet can significantly reduce body fat, studies show. Cap your carb intake at 20% of daily calories and the weight-loss results are even stronger—plus, you can reduce your risk for heart disease and stroke. Some research suggests low-carb diets are even better than low-fat diets: One study in Annals of Internal Medicine found that people who limited their carbs lost eight more pounds than those who cut back on fat. If you cut back on carbs enough, your body learns to burn fat as fuel instead. Studies are mixed on how low-carb diets affect performance, but some evidence suggests that endurance performance can actually improve among people whose bodies adapt to fat-burning fairly easily.
And while the weight room can be intimidating for women, pumping iron is key to getting a toned and fit physique. Don’t worry, lifting heavy weights won’t make you bulky — you just don’t have the testosterone to build the size of a man. Lifting will improve your posture, make your arms, core and lower body more shapely and boost your metabolism by building muscle. Resistance training also helps you hold onto muscle that you naturally lose as you age.
On test days, they were fed either the control meal or the same entrées but altered so that calorie density was reduced by 20% using one of the three strategies. Entrée portion sizes were large enough so that the subjects could consume as much as they desired of the test meals. Leftovers were weighed to determine precisely how much was eaten of each of the test meals.
Even in America, let’s remember the 1970s. Disco was sweeping the nation. Star Wars and Jaws played to packed theatres. If you looked at an old photograph from that era, perhaps you might be amazed at several things. First, why anybody ever thought bell bottoms were cool. Second, it’s amazing just how little obesity there is. Take a look at some old high school yearbooks from the 1970s. There is virtually no obesity. Perhaps one child in a hundred.
Before you start the meal plan, make a pot of the Veggie Soup. Make 2 servings of Overnight Oats, so they can soak in the fridge. It’s also super helpful to prep your veggie snacks—make 4 bags filled with baby carrots and sugar snap peas, and 3 bags filled with broccoli and cauliflower, for alternate days. And if you really want to get ahead, you could also grill the chicken breasts and cook the quinoa and brown rice in advance.
There is plenty that you can do to get even more out of your walks. Stephanie Cyr began her 102-pound weight loss journey by walking for an hour each night—but there was a catch. "I mapped out a 3-mile course that took me through the hills in my neighborhood," she says. Live in a flat area? Alternate 1 minute of super-fast walking with 1 minute of slower walking for a calorie-torching interval routine.
The upshot of all these chemicals floating around is big trouble for big-bellied guys. In a study at the University of Alabama at Birmingham, researchers took 137 men of all ages and sizes and used seven different measurements to determine their risks of cardiovascular disease. The single best sign of multiple heart-disease risks? No, it wasn't the guys' family histories or their cholesterol profiles. It was the amount of abdominal fat they carried.
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.
In terms of the foods, this is not a low-calorie diet. This is not even necessarily a low-carbohydrate diet. This is not a vegetarian diet. This is not a low-fat diet. This is not a carnivore diet. This is a diet designed to lower insulin levels because insulin is the physiologic trigger of fat storage. If you want to lower fat storage, you need to lower insulin, and this may be done even with a high-carbohydrate diet.
I’m in favor of any program that promotes whole foods over hyper-processed fare, and this is one thing the popular diet plans can agree on. Overly processed foods have been linked to weight gain, perhaps because many unhealthy packaged foods (think: potato chips, ice cream, frozen pizza, cookies and the like) lack the fiber found in many whole foods, including vegetables. Fiber helps fill us up, and research suggests that by simply adding more fiber to your menu, you can lose weight nearly as well as a more complicated approach. Consistently choosing whole foods is one way to do this.
