Brief Answer:
Thyroid

Detailed Answer:
What you are describing is not uncommon at all. There can be various reasons for this and typically there is no reason to worry.

One of the most common causes for this is a mildly under-active thyroid gland. In medical terms this is referred to as
PRIMARY ACQUIRED MILD / EARLY / SUBCLINICAL HYPOTHYROIDISM

for which one of the most common causes is CHRONIC LYMPHOCYTIC AUTOIMMUNE THYROIDITIS

which implies that your own body's defence system causes 'bruising' of the thyroid gland, making it permanently under-active.
Often this results in less thyroid hormone production by the thyroid, and replacement for this becomes necessary with a pill called levo-thyroxine.

But whether you truly have this versus some other conditions, requires a comprehensive assessment by an endocrinologist in-person.

When I see someone like you in my practice, I typically order the following blood tests in addition to a detailed physical examination:

CBC (Complete Blood Count, also known as Hemogram; includes Hemoglobin, WBC and Platelet counts)
Electrolytes (Sodium and Potassium in particular)
HbA1c (Glycosylated Hemoglobin = your 3 month glucose average)
Liver function tests (SGOT , SGPT, Albumin, Bilirubin, Alkaline Phosphatase)
Kidney function tests (BUN, Creatinine)
TSH
Free T4
Anti Thyroid Peroxidase (TPO) antibodies
Anti Thyroglobulin antibodies
25 hydroxy Vitamin D
None of these tests require any fasting and can be done at any time of the day

Detailed Answer:
Body building, protein supplements, non veg diet or weight gain are not known to cause thyroid problems.
