<human>: I had my first appointment with a nutritionist as required by my insurance before I qualify for WLS. Just to get it out of the way, I am only doing the surgery as a LAST resort; I don't plan on going through with it unless I still cannot find a way to effectively lose weight on my own in the next 6 months. 

That said, I have found a great balance over the past month which has caused me to lose ~13 lbs. My day generally looks like this:

Breakfast- 1 egg and either leftover veggies from last night's dinner or 1/2 avocado, and a cup of black coffee

Lunch- Leftover chicken and veggies, or a salad with light poppyseed dressing and a piece of fruit

Dinner- 1 protein (salmon, steak, or chicken) and any sort of veggie

I also drink about 2000ml of water a day, and I allow myself a cheat meal every Friday night of whatever I'd like. 

I feel like I've been doing great, and I'm rarely hungry on this plan, BUT the nutritionist told me that I'm eating way too little to sustain this in the long term. She outlined a new meal plan for me that's 1700 calories a day, includes lots of carbs and dairy (which I told her I recently gave up because they make me feel bloated and sick, and I have PCOS and I've always heard they make weight loss harder for PCOS ladies) and honestly, it looked like so much food that it made me feel ill. I suddenly feel discouraged, instead of inspired like I thought I would be.

My question is, does my plan really seem that unsustainable? I don't have a large appetite, and this has been keeping my sugar cravings and binge eating under control, so I'm just really discouraged now that she told me I was doing it wrong. Should I just stop whining and follow her plan? I'm pretty conflicted.

<bot>: Thought I was eating a really healthy diet for a change, saw a nutritionist, and she told me I was wrong and I can't keep it up. Do I go with my gut or follow her professional advice?
