There are several factors that can contribute to weight loss, but the three main factors are:

1. Caloric intake: To lose weight, you need to create a calorie deficit by consuming fewer calories than you burn. This can be achieved by reducing your intake of calorie-dense foods and increasing your intake of nutrient-rich, low-calorie foods.
2. Physical activity: Increasing your physical activity level can help you burn more calories, which can contribute to weight loss. This can be achieved through a variety of activities, including cardio exercise, strength training, and high-intensity interval training (HIIT).
3. Consistency: Maintaining a consistent calorie deficit over time is key to losing weight. This requires a combination of consistent caloric intake and physical activity, as well as making healthy lifestyle choices that support weight loss goals.

It is important to note that everyone is different and the specific factors that contribute to weight loss may vary from person to person. It is also important to consult with a healthcare professional before starting a weight loss program.
