The best: Getting my life back!!! I feel 20 years younger and am doing things now that I haven't been able to do for decades. Rode 15 miles on my bike today and felt great! Hiking hills, riding my mule, climbing stairs, swimming (in a size 10 suit!!!), getting down and up off the floor, no more sleep apnea, no problems with asthma or reflux, no fungal infections in my skin folds this summer, no joint pain, normal BP and blood sugars (ie: no more metabolic syndrome!), wearing cute clothes, feeling "normal" in a crowd, more confidence, not having to size up the furniture in a room to decide which I will fit into, the list just goes on and on. I took a "Biological Age" test, and I am 16 years younger than my stated age! Hurray!!!
The worst: Can't think of any. This is one of the best decisions I have ever made for myself. I LOVE my new active lifestyle and lifelong way of eating. Yes, there can be temptations, but they get easier and easier to deal with as you see the benefits of healthy choices. Sugar and desserts have no appeal at all any more. Neither do processed foods, coffee, soda, or alcohol. I do not even see those as sacrifices - not when I get to eat so many other healthy things.
I guess one thing might be that when I go out to eat, I can only finish about 1/4 of the meal. I take the rest home, but the left overs are really not that great past a day, so I end up giving the rest to the chickens. So that's a waste of money. I am learning to order off the appetizer menu and to not let my eyes get bigger than my stomach. It's a process. Another thing might be that I feel a bit self conscious about my face, which I think looks old and wrinkly now. Others tell me differently and that I look younger, but I just don't see it that way. I am trying to be more out going and cheerful so that the wrinkles look more like smile lines than grumpy lines. That's just a matter of building confidence and learning to accept a great new body, but one that looks a little funny in places.
