Weight loss and gain is quite normal - you just need the overall trend to be down. 500 calories per day is a very low intake; my dietitian recommends a minimum of 800 as soon as you can get up to that level of intake.

It would be helpful if you filled in our profile particularly your start and current weight along with your height, it gives context to questions and helps those replying to give a relevant response.

Even with weight lost surgery scale weight can fluctuate on a daily basis due to a lot of factors: hormones, exercise, dehydration or rehydration, medication, sodium intake etc etc.

Are you eating to your surgeon's and/or dietician's post op guidelines? If you are fairly tall or carrying a significant amount of weight, less than 500 calories may be too low for you and you won't be meeting nutritonal goals...you don't want to lose too much muscle weight you want to be losing body fat.

The weight gain and loss may well be your weight loss pattern, keep track on a daily basis if you are going to weigh daily (but if you can't cope with the daily fluctuation of scale weight don't weigh daily) and you will be able to spot the trends. Its all good as long as the long term trend is going down.

I was before surgery 250lb now I’m 212

So you've lost about 40lb in two months, that is excellent given your start weight, I would say your fluctuations are just that and no cause for panic.

The small weight gains you've experienced (along with the excellent weight loss) may be your weight loss pattern. Very few people lose weight on a continually down pattern...most of us have stalls, weight gains and and losses, this is just how our bodies are even with weight loss surgery.

My suggestion would be to weigh weekly (same day and time). I weigh every Friday morning right after getting up and going to the bathroom.

if you're eating 500 calories or even 800 calories, I can guarantee those gains aren't true weight. You're either retaining water or your intestines are full on the days your weight is up. Weight fluctuation is very normal. As long as the overall trend is down, you're good.
