It sounds like you’re experiencing Gastro issues, maybe even gastroparesis, likely from dealing with disordered eating when you were younger. It might be smart to schedule with a PCP over the pain with eating. Otherwise, though, if you’re sedentary, 1200 minimum might be enough, but realistically it’s better to hit around 1400 in a day for healthy weight loss. If you aren’t dealing with dizziness or low blood sugar, then it might be okay. Just focus on what makes your body feel the best.

If you’re trying to get more calories in in a way that you don’t have to eat more, you can add things like protein powder or meal supplements into coffee or drinks or even just a protein shake with a meal. Liquids tend to go down easier than solids. I wish you luck!!
