So I had my BMR tested with a naturopath. The results were great for that, BMR is 1607 which is almost exactly what the online calculators said. BUT my metabolism is apparently very slow...she said the levels are consistent with hypothyroidism, and my thyroid glands have excess tissue on them.

She said that I will need to eat less than what I have been eating in order to lose and recommended that I eat at my BMR but not to go below. I explained the eat more philosophy and she definitely agreed with it but she said because my metabolism is so slow I just won't lose weight eating that much and that for me, it just won't work right now until we get my hormone levels under control.

She also said I need to cut out gluten and dairy (because of psoriasis) but that it is also beneficial for weight loss with hypothyroidism.

I don't know what to do.

I am getting blood work done to see if my thyroid levels are low but I don't know what to do about my calories.

A 51 year old patient complained of a 15 lb weight gain over the last year despite beginning a strenuous triathlon and marathon training program (2 hours per day, 5-6 days per week).
A 3 day diet analysis estimated a daily intake of only 1000-1200 Calories.
An indirect calorimetry revealed a resting metabolic rate of 950 Calories (28% below predicted for age, height, weight, and gender).
After medications and medical conditions such as hypothyroidism and diabetes where ruled out, the final diagnosis was over-training and undereating. The following treatment was recommended:

Increase daily dietary intake by approximately 100 Calories per week to a goal of 1500 calories
32% protein; 35% carbohydrates; 33% fat
Consume 5-6 small meals per day
Small amounts of protein with each meal or snack
Choose high fiber starches
Select mono- and poly- unsaturated fats
Restrict consumption of starch with evening meals unless focused around training
Take daily multi-vitamin and mineral supplement
Perform whole body isometric resistance training 2 times per week

After 6 weeks the patient's resting metabolism increased 35% to 1282 Calories per day (only 2% below predicted).
The patient also decreases percent fat from 37% to 34%, a loss of 5 lbs of body fat.

I was hooked up to some machine and had to rest for 5 minutes while it took readings and then the machine printed out the results. It was my BMR that was tested not RMR. My BMR is right on track with the online calculators. It was my basal cell metabolism that was low, my number was 28 and it should be around 37.
As I said in my original post she said the numbers suggest hypothyroidism which would be the reason for decreased metabolism.

So regardless of whether it was BMR or RMR (even though their website says it is BMR and the paper that came out said BMR) what are you saying I should do with the information?

I've already raised my calories, did so in April. I have been eating around 1950 and have only lost a pound since June. This is why I went to get tested because I am maintaining a the level that I should be losing at. I had an initial 7 lbs loss from April to June but then really nothing since.

In any case, her numbers indicated I'm at the same level as people with hypothyroidism and I will be getting the blood work back to confirm one way or the other in a couple weeks.

In the mean time I think I will leave my cals where there at and see what happens.

What is more concerning to me is that she recommends I go dairy/gluten free which makes me want to cry lol.

Apparently there is a great coconut milk icecream that's good. Going to try that.
And stuff my face with it while I cry about being gluten/dairy free.
