I am 7 weeks post-op, I was losing weight really well until week 4. Week 5 and 6 I had hit a plateau where I was hardly losing anything, around 1-2lbs per week. My previous eating disorder diagnosed by the military started to resurface so I elected to restart my eating disorder therapy through the VA (military hospital).

My first appointment with my nutritionist taught me something that I'm sharing with you here that completely fixed my plateau and during week 7 I lost 8lbs after barely losing anything the two weeks prior.

I was only eating protein during week 5 and 6 because I was struggling eating enough and I was doing what my surgeon told me which was repeatedly drilled into me that protein was the most important. It felt like protein was the only thing that was important and during these two weeks my stomach was slowly shrinking to the point I was slowly eating less and less.

My eating disorder nutritionist told me you can't lose weight eating only protein because without healthy fats and healthy carbs your body locks itself down. She had me add 1/8th of an avacado or a teaspoon of no sugar added peanut butter to every single meal. That was the healthy fat. She had me add a couple berries to breakfast and a little bit of a sweet potato during lunch and dinner as the healthy carbs. Regular potatoes are an inflammatory carb but sweet potatoes are an antiinflammatory carb. I was not to eat the skin, just the insides. The sweet potatoes and no fruit were my healthy carbs.

I having been diagnosed a-typical anorexia nervosa, was afraid of fats both healthy and unhealthy. I was scared of inflammatory carbs until she explained how healthy carbs and healthy fats function in my body.

Without healthy fats you lose the ability to clot, and it contributed to the function of weightloss but the healthy carbs she explained to me that while even in ketosis, without carbs your body can't burn the fat you have which is why you stop losing weight and plateau

Between week 6 and 7 I added exactly what she told me. I was eating 1 egg, 1/8th of an avacado and 1 strawberry for breakfast. Lunch I had half of a baked fish filet, 1/8th of an avacado, and1/5th of a sweet potato. Dinner was half a baked chicken fillet, 1/8th of an avacado and 1/5th of a sweet potato. Prior to that week I only ate the eggs, fish and chicken nothing else. I lost 8lbs that week and I've slowly been able to eat more. I'm able to eat about 50% more of the protein now with the same healthy carb and healthy fat I've been eating. I'm slowly trying to eat more of the healthy carbs and healthy fats as I go.

I know hitting a weightloss plateau can be a defeating feeling but your body needs more than just protein. Even at the cost of eating a miniscule less amount of protein. I struggled greatly accepting what she told me, fearing what my eating disorder drove me to believe but she was absolutely right and I'm back to losing weight at the record speeds I started. I also noticed what she later explained was the delayed effect where during the week I ate better I was significantly more sore from exercise. This however was not due to the increased diet but rather a delayed effect from having only eaten protein for so long.

Everyone's body is different and every medical professional seemingly tells people different things but this worked for me. So if you're struggling with a weightloss plateau, give this a try. My nutritionist also taught me a bunch of other things to help with pain from eating and such so if you struggle with pain after each meal leave a comment and I can try to help you with what she taught me.

Good luck.

EDIT: Originally my surgeon told me sweet potatoes were not approved for a soft food restriction, so I had been avoiding them. This isn't entirely accurate. The skin is not safe to eat on a soft food restriction diet but the insides are totally fine according to my nutritionist. Just throw any sweet potato into the microwave and nuke it until it's soft. It takes about 5 minutes for me.

There are multiple types of sweet potatoes like orange and white insides, they are all antinflammatory and great for you. Cooked like this they aren't even sweet. I eat without anything on them, no butter, no salt, just microwaved.
