Smartphone calorie-tracking apps may be effective for weight loss only in patients who are already ready and motivated to self-monitor their calories.

If you are highly motivated and willing to log every meal daily, a calorie-tracking app can be a powerful tool for weight loss. However, if you find logging tedious or are too busy, the app will likely not help you lose weight. Consider your readiness for self-monitoring before relying on an app.
