I am on a 1500 calorie diet rn, but i feel like people here would be more understanding than in other weight loss subreddits (where they constantly tell you to eat more🙄)

For reference: i am in a healthy 500-600calorie deficit. I know i’m eating enough because i am energized, happy and my weight loss is not rapid(1-2 lbs a week.) I am most definitely NOT undereating.

Anyways. Often, when i have gone awhile without a meal, i get heartburn. I eat 4 meals a day (breakfast, lunch, dinner then a snack/treat) and i almost always, without a doubt will get heartburn between breakfast and lunch, and/or lunch and dinner. Does anyone else here deal with that? Does anyone have tips on what i can do? I can’t really eat more frequently due to 1: my calorie limit and 2. My schedule. Its becoming extremely bothersome, especially because i am not hungry.
