We generally recommend weighing once a week, on a designated day, and first thing in the morning after using the restroom and before eating/drinking to keep the process standardized and consistent.
If you prefer to weigh each day, know that daily weight fluctuations are normal and often unavoidable. Weight naturally fluctuates throughout the day due to normal fluid shifts caused by exercise, food/beverages, hormones, medications, salt, weather, water intake, restroom utilization, and other factors.
Know it is also okay if you want to focus on getting into a good routine with your meals and snacks and not weigh for a while (track healthy habits instead). Just do what works best for you!
We also recommend setting non-scale goals like how your clothes fit, how you're feeling, health goals like stress management, sleep habits, and fitness goals. All of these things factor into a much broader picture of your overall health and happiness!
If tracking progress with a scale, a healthy weight loss target is generally 1-2 pounds per week.
