Weight loss journey

Ok. I need to seriously update. I've been so busy with yardwork since Friday and I had the finishing touches to do on Monday(yesterday) and I was exhausted when I came in. I had a long, well-deserved shower and realized that I didn't have food in the house. So I had to trek to the grocery store and be back before the kids got home from school. When they're home, it's another story... getting supper ready and getting some of them out of the house for their various activities.
To make a long story short, I was busy and didn't update. So I have to backdate to Monday.
Sept 24: I couldn't believe it. Somehow, with all the gardening I was doing all weekend, I guess I managed to eat right and get in all my food groups. I stepped on the scale and and I went down 1 lb!! I was actually in the 150's! I had hoped I would be by Monday but thought I ruined my chances due to the pound weight gain on Saturday... all due to my poor food choices for Friday... I overate pizza!
My wishes to be down to the 150's by Monday came true. Victory #2!
Current status: down 1 lb
Current weight: 159.5 lb
Sept 25: Can you see me doing my happy dance? I dropped 0.5 lb! What is going on? Is it the food I'm eating? Is it the total body workout I've been having doing heavy gardening? I don't know for sure but, I am so pumped! This is the reward I need to keep myself motivated and stay on the right path! 
There is no gardening for me today. I still have a few plants to get in the ground before the frost hits but I'm going to leave it for tomorrow. The weather is supposed to get a little warmer and, besides, I need a break! But, I have a very messy house! I was getting the outside looking pretty but the inside was slowing turning into a dump. Needless to say I'll be cleaning up from top to bottom, doing laundry and making an awesome supper!
