Serious, good diet will reduce the weight, water is your best friend, your biggest meal should be breakfast and your smallest meal should be dinner. Lots of fruits and stuff like that. Lots of walking. You be surprise how much weight you can lose. My daughter went from 240 to 130 lbs and it did take a year but now I got her working out and stuff.
The Grom I'm buying is for her to use when going to College and short trips to the gym and local grocery store.
I used the added power/weight gains as motivation to lose some weight...went from 205 to 175 so far...but this was for my MV Agusta Brutale 910S with 125 HP at the rear wheel...buuuuut this will really help me hit a higher top speed on the grom too!!!
I did weight watchers with my wife, I was sceptical at first but I started at 300lbs and I'm down to 250! Its always hard to stay motivated but if you have other people doing it with you, then it becomes easier. Kind of glad to see another portly fellow interested in the Grom
