“Weight loss apps can be a great way to help adults be aware of their nutrition and lifestyle habits,” says Jaime Coffey Martinez, a registered dietitian and owner and founder of Nutrition CPR LLC, a health and wellness center. Using a weight loss app on your smartphone or laptop can help, giving you a convenient and reliable way to track your slow but steady progress. According to the CDC, people who lose weight gradually and steadily (about 1 to 2 pounds per week) are more successful at keeping weight off. A recent global study by Ipsos carried out across 30 countries found that 45% of people globally say they are currently trying to lose weight.
