Okay, so when I say "you were 4 pounds heavier 5 months ago", take that to mean "You gained around zero weight in 5 months." The point remains exactly the same. You're eating needs drastic improvement.
Try to decide if you "like" weighing 120 more than you "like" the taste of potatoes, fruit, and other vegetables. Also, potatoes are a cinch to cook - baked in the oven, boiled, or microwaved.
As far as you need to be concerned, those things have basically nothing to do with each other. A lack of saturated fat is not what's preventing you from seeing progress. For someone in your condition, I consider saturated fat, and fiber, minutia. If you're going to track numbers, stick with total calories, protein, fat, carbs. If you make intelligent food choices, the healthy fats should take care of themselves.
