You know strength training is the best way to trim down, tone up, and get into “I love my body” shape. But always reaching for the 10-pound dumbbells isn’t going to help you. “Add two or three compound barbell lifts (such as a squat, deadlift, or press) to your weekly training schedule and run a linear progression, increasing the weight used on each lift by two to five pounds a week,” says Noah Abbott, a coach at CrossFit South Brooklyn. Perform three to five sets of three to five reps, and you’ll boost strength, not bulk. “The short, intense training will not place your muscles under long periods of muscle fiber stimulation, which corresponds with muscle growth,” Abbott explains.
Low-fat diets also can help you lose weight.16 But the amount of weight lost is usually small. You can lose weight and lower your risk for heart disease and stroke if you follow an overall healthy pattern of eating that includes more fruits, vegetables, whole grains and beans that are high in fiber, nuts, low-fat dairy and fish, in addition to staying away from trans fat and saturated fat.
Carbohydrates should provide 45%–65% of your daily calories. Most of those calories should come from the complex carbohydrates in high-fiber and unrefined foods, such as bran cereal and other whole-grain products, brown rice, beans and other legumes, and many fruits and vegetables. These carbohydrates are digested and absorbed slowly, so they raise the blood sugar gradually and don't trigger a large release of insulin. People who eat lots of these foods have higher HDL ("good") cholesterol levels and a lower risk of obesity, diabetes, and heart disease. A good amount of soluble fiber in the diet lowers LDL ("bad") cholesterol, and high-fiber diets reduce the risk of intestinal disorders ranging from constipation and diverticulosis to hemorrhoids. Some studies have shown that fiber may help reduce the risk of colon cancer. Men need more fiber than women: 38 vs. 25 grams a day before the age of 50 and 30 vs. 21 grams a day thereafter.
In the past, women have often tried to make up deficits in their diet though the use of vitamins and supplements. However, while supplements can be a useful safeguard against occasional nutrient shortfalls, they can’t compensate for an unbalanced or unhealthy diet. To ensure you get all the nutrients you need from the food you eat, try to aim for a diet rich in fruit, vegetables, quality protein, healthy fats, and low in processed, fried, and sugary foods.
Trans fatty acids, also known as trans fats, are solid fats produced artificially by heating liquid vegetable oils in the presence of metal catalysts and hydrogen. They also pose a health risk, increasing LDL or "bad" cholesterol and increasing your risk of coronary heart disease. They are often found in cookies, crackers, icing and stick margarine, and in small amounts in meats and dairy products. Beginning in January 2006, all food manufacturers had to list the amount of trans fatty acids in foods, resulting in a significant reduction in the amount of these fats used in prepared foods. In its guidelines, the American Heart Association notes that trans fats increase risk of heart disease by raising "bad" LDL cholesterol and should be avoided as much as possible. In addition, research has shown that trans fats can also decrease "good" HDL cholesterol, increase inflammation, disrupt normal endothelial cell function and possibly interfere with the metabolism of other important fats—even more evidence that they are very bad for overall health.
“The reason most people don't see changes isn't because they don't work hard—it's because they don't make their workouts harder,” says Adam Bornstein, founder of Born Fitness. His suggestion: Create a challenge every time you exercise. “Use a little more weight, rest five to 10 seconds less between sets, add a few more reps, or do another set. Incorporating these small variations into your routine is a recipe for change,” he says.
Although growing bodies need plenty of energy in the form of calories, many children and teenagers consume way too many, says Ruth Frechman, RD, a spokesperson for the American Dietetic Association. The latest findings from federal surveys show that 18% of adolescents and teenagers are fatter than they should be. Kids who are obese are 16 times more likely than healthy weight children to become obese as adults, other findings show.
When layering for an outdoor activity this winter, consider a compression fabric for your base layers. “These fabrics are fantastic at wicking moisture from the body, which allows you to sweat and breath while keeping you warm,” says Chiplin, who notes they can also reduce fatigue and muscle soreness so you’re ready to head out again tomorrow. Consider throwing them in the dryer for a minute before dressing to further chase away the morning chill.
Adopting a plant-based diet could help tip the scales in your favor. A five-year study of 71,751 adults published in the Journal of the Academy of Nutrition and Dietetics found that vegetarians tend to be slimmer than meat-eaters even though both groups eat about the same number of calories daily. Researchers say it may be because carnivores consume more fatty acids and fewer weight-loss promoting nutrients, like fiber, than herbivores do. Go green to find out if it works for you.
Good sources of iron include liver, kidneys, red meat, poultry, eggs, peas, legumes, dried fruits and dark, green leafy vegetables. Three ounces of cooked chicken liver contains 7.2 mg of iron; a cup of cooked spinach contains 6.4 mg. Your health care professional will probably recommend iron supplements during pregnancy (probably starting at 30 mg per day).
Although canola oil appears to be good for the cardiovascular system, two Harvard studies have raised concerns that ALA might be bad for the prostate. In 1993, the Health Professionals Follow-up Study of 47,781 men published a major evaluation of dietary fat and prostate cancer. It found that saturated fat from animal sources such as red meat and whole-fat dairy products was linked to a 2.6-fold increase in prostate cancer. But the study also provided some disquieting news about ALA: Men who consumed the most ALA were 3.4 times more likely to be diagnosed with prostate cancer than those who had the lowest dietary intake.
A year later, a second Harvard study added to the concern. The Physicians' Health Study of 20,885 men did not evaluate diet per se, but it did measure the blood levels of ALA in 120 men who developed prostate cancer and compared them with the levels in 120 men who remained free of the disease. Men with moderately high ALA blood levels were 3.4 times more likely to develop prostate cancer than men with the lowest levels; curiously, though, men with the very highest levels were only 2 times more likely to get the disease.
