I've heard that the last 20lbs of weight is the slowest to go. I'm in that same range myself but haven't had all that much problem yet. You can tone your body with exercise and aerobic activity. I personally like caffine as it's a stimulant and can help with fat loss. What I think you mean is you gave up cokes or coffee and that's helping you. I take a suppliment and drink caffinated green tea, on top of drinking water.

Stick to your guns. You're almost there.

Good luck!
