Any advice for a slow loser ?

After looking at your diary, I am surprised you are not gaining instead of losing. You are most days way over the calorie goals, sorry. And I suspect you are really overestimating what you burn too.

I have to agree with the others advice, I took a pretty good look through your diary and noticed a few things.
-occasional days with minimal to no logging, don't know if you missed them or hardly ate those days, or only half logged...
-many days with sodium levels pretty high =water retention
-I have to agree with the either overestimating calories burned or underestimating food intake, maybe a bit of both? I know MFP usually overestimates calories burned, try to only eat half back fora while and see how that goes.
-consider investing in a heart rate monitor. I personally don't use one but if you are overestimating workout calories burned this will help with accuracy
-food scale if you don't already use one, which I personally do use for any solid foods to get an idea of what a true serving is and so you aren't eyeballing portions.
-Finally I noticed a lot of days lacking lunch but having a high calorie snack later, nothing wrong with treating yourself but usually your breakfast and supper are very high calorie then there's a big gap in the middle of your day, followed by something else high calorie I'm assuming at night. I don't know if dispersing your calories through the day might help more but give it a shot. I find if I'm relatively full I won't be as likely to have something less healthy later in the night. Calories can't tell time but if you're a person who generally makes bad choices later in the night then work on integrating more healthy snacks and more balanced meals in the day. ---Also I don't know a lot about protein powder but it seems liked you have a lot of it. Maybe try getting more natural protein sources through the day, and I didn't notice much in the way of veggies so maybe try to get more of those in. They're especially good for making those really high calorie meals into lower calories while still filling you up.

Try changing things up a bit, all these suggestions may or may not work but it's worth a shot. In the end it should be about having a moderate calorie deficit =weight loss! simple as that. If your health issues could affect your weight loss you should see a doctor and maybe work with a dietician to personalize a plan that works for you if what you're doing isn't working.
