Stubborn extra weight/fatigue

[tctrek]

+1 on getting thyroid checked. Unexplained weight gain and fatigue are prime candidates.

Also, if you are taking any medications that might block the absorption of nutrients, you need to think about when (time of day) you take them and what you eat/drink immediately after. I take Metformin and found out that it blocks absorption of calcium which in turns gave me a B12 deficiency.

Finally, you should log your food intake. I'm 57 and I have to eat less calories now than I did in my younger days even though I am very active now and barely got off the couch in my younger days! I log everything I put in my mouth to stay within a proper calorie range and ratio of carbs/protein/fat.
