1.Six meals a day. This is imperative as it raises your metabolism.
2.Only have carbs in the first four meals of the day, if fat loss is slow make this three meals.
3.Do cardio in the morning if you can, because of the carb cutoff the night before your glycogen stores will be depleted and you will be in an optimal fat burning state.
4.You could do HIIT instead of running. Further raises your metabolism throughout the day. Remember running and weights don't go together well, but if you aren't that bothered about muscle gain and don't mind it being slower then running is fine. Very individual whether you can gain weight with running or not. But HIIT something like running 1 minute, brisk walk 1 minute and alternate between that for 15-20 minutes is a good bet.
This should be enough, especially at 16.
