Though fad diets might sound appealing and bring you short-term weight loss, they’re not sustainable, Tressler explained. Some are even risky. A diet that emphasizes a high fat intake, for example, could lead to spikes in cholesterol.
Don’t be entirely focused on weight. “A scale really only measures the Earth’s gravitational pull on your body,” Tressler said in a Penn State news release.
It’s more important to know your numbers — cholesterol, triglycerides, blood pressure, she said. They’ll give you a better picture of your health and the safest ways to lose weight.
Losing weight is basic subtraction and requires eating less than you need to maintain your weight. Age, gender and activity levels also make a difference in the number of calories you need to maintain or lose weight.
App stores and websites offer calculators to help you keep track. Tressler suggested the Harris-Benedict equation, which can calculate how many calories your body would need if it rested for 24 hours. Just don’t become too numbers-focused, she said.
“It can become very restrictive,” Tressler said, and can lead to eating disorders.
Tressler recommends “intuitive eating” based on lifestyle needs. “There are no bad foods,” she said, “only bad portions.”
The vast majority of weight loss can be controlled by what you eat, Tressler said. Some websites and articles say losing weight is the result of 80% diet and 20% exercise.
Exercise also is good for heart health, muscles and well-being. Tressler suggests 30 minutes per day, five days a week, of something you like such as dancing or walking, and then pairing that with a healthy, sensible eating plan.
“Maintain a balance,” Tressler said.
