Having trouble eating enough

Is your goal to lose weight (fat)? If so, you need to eat less. Moving more is good too, but eating less is most important. When you lose weight, you are "eating" off your fat stores. Are you losing weight? If so, you are eating less. Are you losing weight faster than expected? If not, you're not eating too little. In order to be sure your're eating enough but not too much, you have to track correctly (if you don't want to just go by how you feel and your weight trend). "Healthy" foods tend to be high volume so it fills you up fast, and takes a bit of effort to eat. But it also tends to be boring. When we start something new, it feels fresh and exciting, and this can make us push ourselves beyond what is really good for us. We can do it for a while, but over time our resolve wears down, especially when weight loss start to slow down (which it will), and we give up, and go back to what we used to eat, plus a little extra to make up for lost time.

What I would suggest, is that you just eat food you like, but track it correctly. This means picking entries that have the same nutritional information as the packaging, or check with producer's/restaurant's website or the UDSA database, weigh everything and log the amount you actually eat, use the recipe builder, the same way, when you cook, never forget or leave out anything, never cheat or guess or estimate, and hit your calorie goal (+/-50) every day.
