Your health can benefit from determining exactly how many calories you need. Many calorie-counting and fitness apps can help you do it for free.

Meanwhile, some people disagree with counting calories. Registered dietitian, Tammy Karni, said she never puts importance on calories.

“A calorie for you can be very different than a calorie for me,” she said. “My focus is more on nourishing your body and like increasing your protein mass because that’s your metabolic currency and keeping that healthy and balanced, so your hormones are balanced; You have enough muscle mass, and then calories really don’t matter as much.”

She says people are undereating protein especially as we age when keeping muscle mass is important. Karni prefers focusing on macronutrients over calories.

The USDA also encourages everyone to focus on nutrient-dense foods and avoid added sugars and high-calorie foods.

Nutrient-dense ex: Salmon, kale, eggs, fruits & vegetables.
