I started out with Spark & I weighed daily. Drop a pound, up 0.5, down 0.5, up 2 pounds, down 1. It nearly drove me crazy trying 2 get something N a steady downward trend. All of this is compounded because I have diabetes & heart problems, balancing water intake and out-flow is very difficult as my
water weight can fluctuate. I switched 2 weekly weigh-ins & I can see a steady downward trend without the water shift problems. Women have water weight variations more severe than mine. I only weigh weekly now, and I'm not really concerned if I miss a weigh-in. I have gone 4 weeks. Sanity is OK now.
