Measurements 5/2/2012

Should I start to be getting worried, since I am losing way too much weight? My stats are as follows:

Weight - 98kg

Left Bicep	34.5cm
Right Bicep	34.5cm
Waist	95cm
Hips	109cm
Left Thigh	58cm
Right Thigh	58cm
Total	389cm

I really do need to start hitting the weights, as I am beginning to feel light, even thought my waist is shrinking, so are my arms and legs, two areas where I don't really need to lose weight...
