try a refeed meal, this will bring leptin back to normal. When you stop producing leptin you stop losing weight. Refeed once per week.
A proper re-feed should consist of 60% carbs, 30% protein, and 10% fat(or there abouts). No more than 10% above your calorie level during the non load days.
For a proper re-feed, focus on high quality carbs sweet potato's, pasta's, breads and so on.
