Your first sentence made me laugh, but I realize too how true it is. Both for me and I'm sure many who are starting a healthier life style. After meals now I don't feel like I need to sit down, I still feel like I have energy. It's been years since I felt like that! In previous weight loss attempts I've gone on very very low calorie diets that left me with as little energy as my high calorie diet. I would get slimmer but stayed flabby and feeling poorly. This time I've lost slower but I feel stronger. I hate to even think how many calories I must have used to consume on a daily basis in soda alone.
