How I manage my weight gain for 2 years of hypothyroidism.

I had hypothyroidism for more than 2 years, but am happy to say my weight always kept between 139 to 141 pound range. Here is some things I keep doing in following ways
1. Keep strict medication compliance. I take thyroxine pills the first thing in the morning with empty stomach.
2. Watch my weight  every day. if weight increase, I will cut down my calories intake
3. Go to gym and exercise everyday for at least one hour
4. Take enough nutrients including protein, vitamin and minor  mineral
