where am I going wrong?

Those people that told you to eat more are right! I always stricktly stick to the MFP advice and that is working best for me. Just give it a try for a week or two and see what happens!

You're losing nearly 2 lbs per week. That's a healthy and sustainable loss.

Can we first start by changing your topic question from "where am I going wrong" to "what am I doing right"? You've lost 16.1 lbs which is awesome! You've made some positive changes in your eating habits maybe even to the point of possibly depriving yourself of too few calories consumed which can sabotage your weight loss. Our bodies are like engines, we need fuel (food) to operate efficiently. However, if you put in the wrong fuel (bad gas) your engine will seize up. You won't be able to lose weight at a reasonable rate. Maybe that's a silly analogy but it is important to eat the right kind and right amount of food for you body. It is such a tricky balancing act.

What has worked best for me personally to lose 47 lbs (slowly) is following a plan that my daughter, a PT and Wellness expert, designed for me. It's nothing complex. The key is small meals every 3-4 hours that consist of low carb, high protein, no sugar, and low sodium. The important thing to remember is just because your eating more meals DOES NOT mean that you are consuming more calories.

It's also fantastic that you joined a gym and you're moving your body. Another excellent way to fire up your metabolism and also another thing that you are doing right!

Please listen to me when I say, even though you don't know me, don't hide behind your sluggish thyroid. I take a high dose of Levothyroxine for hypothyroidism. I have in the past but never will again use this for an excuse. Just because we have thyroid disease, only means that it is an extra challenge to lose weight NOT impossible to lose weight!

So as I see it CC, you have a lot more 'Right' going on than you do wrong.

Best Wishes for success

BMR stands for basal metabolic rate and represents the calories that your body expends when completely at rest (not accounting for any activity at all). However, the BMR figure that I quoted is for a typical individual with your stats. Because of your thyroid issue, your BMR may actually be lower than this.

If your insurance will cover it, then another trip to the doctor and new bloodwork may be advisable. I think that, especially in the first year of diagnosis, more than two visits are warranted in order to get your medication dosage regulated properly.

Why so few calories?

I started at 327 pounds - shooting for losing 1.5 pounds a week, and after losing almost 70 pounds, I'm still eating 2330 calories a day.

1200 seems like too few calories for where you are right now. You will have serious difficulty sustaining that amount of calories, for the long-term. Perhaps decrease your pounds per week loss in your goals, increase your amount of workout time, or something similar?

You will plateau faster as your metabolism decreases and have more difficulty keeping it going for the long-term commitment it's going to take to do it at that level, IMHO. Think less diet and more lifestyle.

P.S. Nice job on the loss!!

Condiments I use regular are chilli flakes, garlic powder, oxo, occasionally coarse grain mustard, Worcestershire sauce. Soy sauce on sushi.
Olive oil only. I dont pour it, I put on kitchen roll and grease the oven tray.
Flora light is the marg I usually use.

Not a fan of ketchup, mayo etc unless on stuff like pizza, chips, burgers,kebabs. All of which im not eating at the mo. But if I use, I'll be sure to measure.

You don't have any of these logged.

Olive oil alone is 120 calories per T.
