One thing I did forget to mention, that I noticed in your first post, when you said that eating an apple left you hungrier than eating nothing at all, that could be a sign that you have insulin resistance/issues with carbohydrates.

Fruits contain relatively simple carbohydrates, meaning sugars. Fruit sugars break down quickly, and can lead to an insulin spike (hunger).

A snack or meal of fruit only leaves me hungrier than eating nothing, also. I have to add some fat or protein with fruit, or I'm hungry again only a short time after eating. So I'll eat an apple with a piece of cheese or a tbs of peanut butter.

A lot of "food combining/timing" theories are a lot of nonsense, but some have merit. If you use a food journal, and write down not only what and when you eat, but also when you feel hungry, and rate your hunger, you'll be able to find patterns that help or hinder you. You'll find which foods make you hungrier and which satisfy longer.

I'm not pushing a low-carb or Paleo agenda (though I am biased in favor of them), because I think different people do better on different diets.

It's that diference that brings up another issue about "healthy eating." "Just eat healthy," is absolutely meaningless, because there is no one-size-fits-all "healthy diet." What is healthy for one person may be unhealthy for another. At it's extreme, that's easy to understand - if you're allergic to wheat then whole-wheat bread isn't healthy for you.

What constitutes a healthy diet, depends upon your specific needs. A healthy diet for an 80-lb, starving adult is much different than for a 310 lb person with insulin resistance/borderline diabetes like myself.

There is no "just eat healthy" without taking your specific physiology into account.

Now "eat healthier," is a somewhat easier concept. If you're overweight; fruit, vegetables, lean meats, healthier fats and whole grains are going to be better choices than fast food. That's a no-brainer, but it can get a whole lot more complicated than that, if you want the optimal diet for your body and your health goals.

I spent many years making what seemed like healthy choices. I learned that is entirely possible to maintain a morbidly obese weight on "healthy" foods. No candy, no ice cream, no chain restaurant fast food - and no weight loss. Because even "healthy calories" add up quickly.

I have difficulty avoiding foods that increase my hunger. It's easy to forget that watermelon can be nearly as bad as a candy bar (at least with a candybar I tend to stop at one, whereas watermelon I'll eat until I'm bursting, "because it's healthy."

That doesn't mean I buy candy bars and avoid watermelon - I just have to keep every choice in perspective. And for me, it boils down to carbohydrates, because I overeat them. High-carb eating makes me feel like I'm starving, even if my stomach is full to the point of discomfort. It's a crazy feeling to feel both stuffed and starving at the same time.

Weight loss is a complicated experiment, and I really think the biggest key to success is being willing to continue the experimentation. It reminds me of the saying "you've got to kiss a lot of frogs to find your prince." If dating is like that, dieting is worse. I dated less than a dozen men to find my husband, it's taken several hundred diets (and 39 years) to find the right diet for me (it wouldn't have taken so long if I hadn't spent most of those years trying and retrying the same diet. I didn't know that I had to reduce carbs to controll hunger, in fact, I didn't think reduced carb diets were healthy at all. I had to redefine "healthy" to succeed).

Lots of good advice here.

I just wanted to add that apples make me feel hungier also.
Therefore, I do not eat apples :)

Best wishes to you. You can do it !
