The Noom app does not show users their levels of micronutrients (such as calcium, iron and vitamin C) or macronutrients (carbohydrates, proteins and fats), but its overall calorie estimates are rather accurate.
Noom distinguishes itself from other applications by its emphasis on well-being as opposed to traditional dieting. The app provides users with "coaches" that motivate them to achieve their nutrition goals.
"Weight loss is much more than writing things," said Andreas Michaelides, head psychology chief of Noom. "It's really about changing behavior."
Unless someone has a clinical diagnosis and must follow their micronutrients, he said, it is more important to adopt healthy habits for life.
"Most people, without the help of a food database, would not be equipped to have an overview," said Michaelides. "A lot of the calories in food are buried in their meals."
Michaelides added that no nutrition app should tell people to consume more calories because they've been exercising. Following physical activity can help people set goals and learn new behaviors, but this should not be a reason to change healthy eating habits.
"People should not be obsessed [with logging], "he said." Ultimately, it's really about creating sustainable and sustainable habits. "
