Back in July I started a weight loss regimen that I planned to use to help me lose 30 pounds this school year. Since then I've used my ellliptical trainer almost every school day, started going for neighborhood "head clearing" walks in the evening, and took up hot yoga (Bikram style) twice a week, in addition to severely cutting back on the quantity and improving the quality of my diet.
Yes, weight fluctuates daily, and even more so throughout a day. But I weigh myself each morning when I get up, on the premise that such consistency helps provide better daily data.
This morning, for the first time, I passed the 18 pound mark :-)
