A ketogenic diet (KD) is one that’s very high in fat, moderate in protein, and very low in carbohydrates. Traditionally, KDs have been used to help treat children with epilepsy (seizure disorder), but over the past few years they have gained popularity in the athletic community for purported performance-enhancing effects. At this time, the scientific evidence does not support the use of KDs to improve performance; in some cases, it can even decrease performance. It also can be difficult to maintain a ketogenic diet due to its extreme dietary constrictions, which come with potential negative side effects. Read more...
An important thing to know about stress fractures is how to avoid them. A stress fracture is a tiny crack in a bone that happens when your muscles can’t absorb shock and transfer stresses to the bone. Most occur in the lower extremities, especially the lower leg and foot.
A stress fracture is usually an overuse injury that develops over a long period of time—from weeks to months. They’re especially common among military recruits, in about 3% of men and 9% of women. And since it can take several weeks to months for a stress fracture to heal, the best approach is to avoid getting one. Here are some tips for prevention:
- Use the progression principle of training: Gradually increase your training intensity, usually by no more than 10% weekly if you exercise 3 or more days a week. Slowly incorporate higher-stress activities such as jumping and interval training into your workout. Set incremental goals to help you develop your training routine step-by-step.
- Check your footwear and make sure it matches your training routine. Replace old or worn footwear.
- Check your form. Are you moving properly when you exercise or does your form put you at risk of injury?
- Pay attention to early signs of injury. Unusual muscle soreness and other aches and pains can be a sign of injury and/or imbalances that could worsen if they aren’t addressed early.
- Monitor your diet, specifically calcium and vitamin D intake. To learn more, read the National Institute of Health’s Dietary Supplement Fact Sheet on calcium and HPRC’s article on vitamin D.
It’s important to recognize a stress fracture and get medical help early, as described by the American Academy of Orthopaedic Surgeons. The Mayo Clinic provides more information on symptoms. And check out HPRC’s Injury Prevention section for more on how to avoid injury.
Are you including plenty of iron-rich foods in your eating plan? If you tire easily, have trouble concentrating, or experience shortness of breath, you might not be getting enough iron. It’s an essential nutrient that helps carry oxygen throughout your body, and it’s especially important if you engage in daily exercise.
Anyone’s at risk for iron deficiency, so be sure to eat a variety of iron-rich foods. Otherwise, your physical and mental performance could suffer. Check out HPRC’s new postcard on how to eat to succeed in your training envIRONment for more information. If you’re eating well, but still lacking energy, be sure to talk with your doctor.
Since the number one killer of men and women in the U.S. is heart disease, it’s important to know your cholesterol numbers. Cholesterol, an important substance made by your liver, forms cell structures, produces hormones, and helps with digestion. Here are the cholesterol numbers to know:
- Good, or high-density lipoprotein (HDL), cholesterol helps prevent fat and cholesterol from clogging your arteries. Know your HDL: Think H for healthy! A healthy number is greater than 60 mg/dL.
- Bad, or low-density lipoprotein (LDL), cholesterol can cause cholesterol buildup and block your arteries. Know your LDL: Think L for lousy! A healthy number is less than 100 mg/dL.
- Your total cholesterol score should be less than 200 mg/dL.
Starting at age 20, get your cholesterol checked every 5 years. Doctors use these numbers along with your age, blood pressure, and weight to help you manage your cardiac health. Smoking, diabetes, and heredity play important roles too.
There are ways to manage your cholesterol and heart health! Regular physical activity can lower LDL and raise HDL. A diet low in saturated fats can help as well, so make sure to check out the New Dietary Guidelines for Americans.
March is National Nutrition Month® and the Academy of Nutrition and Dietetics is encouraging everyone to enjoy different food traditions and celebrate the role that food brings to their lives. This year’s theme, “Savor the Flavor of Eating Right,” points out that the how, where, when, and why are just as important as what you eat. Making sure to enjoy the sights, sounds, memories, and interactions associated with eating are essential. Slowing down and taking time to appreciate the positive emotions that accompany mealtime are also important steps to developing a sustainable healthy-eating plan. Developing an eating pattern that includes nutritious and flavorful foods is the best way to savor the flavor of eating!
Every March, the Academy sponsors its month-long nutrition education campaign to share its message that improving overall well-being requires a lifelong commitment to healthful lifestyle behaviors, including nutritious eating practices and regular physical activity.
