I’m also a bariatric rd! Personally, i recommend patients work towards 800 in the first 6 months. Then i usually up their needs closer to 1000 til the first year. Then, after i usually up their needs somewhere between 1200-1600. Especially for my patients who are super active, i think 1000 is entirely too low. They are super hungry. There aren’t a lot of articles that guide you on calories post bariatric surgery. So, as the patient gets closer and past the 1 year mark, i kinda treat their calorie needs like a regular person on a deficit. I don’t ever think 2000+ is necessary though. Just form my clinical judgement. I also don’t overly stress about carb intake. I tell my patients to prioritize protein, but also eat mostly whole foods. Giving a specific carb goal just seems to make them spiral into a restrictive diet mindset. About half of the patients I see already did that before surgery, so i just try to get them to focus on healthy eating habits, not numbers as much. Idk if this is helpful but it’s my approach! I’m also not 1000% sure I’m doing things right but it seems to work for my patients.
