This study is looking at new ways to help people keep weight off after losing it. It uses different behavioral interventions, including learning relaxation exercises, setting goals related to your values, tracking your diet to stay within a calorie goal (1,200-1,800 kcal/day), and scheduling physical activity and sleep. The study aims to understand how your behaviors, feelings, and surroundings affect your weight over time. You might be able to join if you are between 18 and 70 years old, can read English, have a Body Mass Index (BMI) between 25 and 50, can walk two city blocks, and own a smartphone. The main goal is to see how your weight changes daily over 52 weeks. The current recruitment status is unclear.
