Great for you, determination is key!
You're right.....it doesn't matter when you do it, it matter's that you do it....I can go in the morning because my schedule is free for now...but going in the evening or night is great as well!
I have to agree. In winter time here in Australia, I tend to put on a few kilos. It's coz I am not doing my daily walks or weights. Simple. Hypo does tend to make people eat more, and many fail to keep a food diary. As I always say, a calorie eaten has no idea that it can't be a calorie burned. It just takes more effort to lose that calorie when hypo. I know I struggled BIG time to lose the 40 kilos (over 88 lbs) in the time I did. But it can be done. Will power is one of the best medicines along with the thyroxine!
Good on you for getting up and doing your gym work. Personally I like to stay in bed! I prefer to go out in the afternoon, so it shows, what works for one is not going to work for another. If someone reading your post thinks, Oh gawd, I have to get up early to lose weight? Then it might put them off. I say to them, NO! You can go to the gym, go for a walk, lift cans of pinto beans, ANYTIME that suits YOU. The thing is to TRY!
Cheers!
