I am fairly new too, joined Jan 1! My New Year's Resolution is to get down to my goal weight and STAY THERE!
I find it very challenging to to get my macronutrients right as well carbs/fat/protein! I think a safe range is 40% carbs, 30% fat and 30% protein. Not an easy task!!
I do find that eating more whole foods and less processed food really does help with this. The problem with the processed is if it is low in fat, it is usually high in sodium or sugar! If it is lower in sugar it is higher in fat, or it is full of aspertame or some other chemical sweetener. It is challenging to say the least. Cooking from scratch seems to be the best bet for keeping your fats, sugars and carbs in line. The only processed foods I actually eat are cereals, breads, yogurt and cheese...everything else is natural. Another killer is the dressings, sauces, butter, margarines, etc! It isn't the food, it is what we PUT ON the food!!
I have discovered that balsamic vinegar is delicious on a number of different veggies and even some fruits. Mixed with a wee bit of olive oil it makes a tasty and healthy dressing.
I don't know if any of this is helpful or not! Good luck!
