The real key is to limit simple carbohydrates, which provide little to no nutritional value, but add calories you don't need.  Depending on other health issues you might have, a keto or mostly keto food plan might work best for you.

To keep from getting bored, try a variety of herbs and spices to season foods.  Make interesting food combinations that you've not tried before.

Good luck and let us know how you're doing.
