Guragain enjoys fiber-rich oatmeal for breakfast. Oatmeal is a good choice for a healthy meal, providing it doesn't have added sugar, and is shown to help lower cholesterol. "It's a big win for your health — and you get it done before leaving the house in the morning," says Beth Czerwony, RD.

Guragain likes to both walk and run on the treadmill. "A study of over 1,000 men and women found that those who walked at least 20 minutes a day, at least 5 days a week, had 43% fewer sick days than those who exercised once a week or less," says Harvard Health. "And if they did get sick, it was for a shorter duration, and their symptoms were milder."

Guragain loves all kinds of seafood, from grilled fish to sushi to shellfish dishes. "A serving is 3 ounces cooked, or about ¾ cup of flaked fish," says the American Heart Association, which recommends eating two servings a week. "Fatty fish like anchovies, herring, mackerel, black cod, salmon, sardines, bluefin tuna, whitefish, striped bass and cobia are high in omega-3 fatty acids."

Guragain lifts weights at the gym, which is a great way to build muscle and burn fat. Weight training is also beneficial for bone health. "Weight training is the best way to keep the muscle mass you have and even increase muscle mass you may have lost with aging," says Shawn Pedicini, a physical therapist at Harvard-affiliated Spaulding Rehabilitation Hospital.

Guragain uses resistance bands as part of her mat workouts. "With any type of exercise, you have to maintain proper form and posture, just like you would if you were using an exercise machine," says exercise physiologist Christopher Travers, MS. "And the reps and resistance may change based on the individual. Just take your muscles to fatigue to get the most out of a session."
