Starting a 3 week new me jumpstart - wanna join

HI All
I am going on vacation in 3 weeks and i thought this would be a good oppertunity to jump start a better lifestyle. Since havign my son i havent been myself and i have been craving sugars and starches alot, not eating as many veggies and not finding the time to work out

So far i have started today with part juice/healthy eating plan

Today so far i have a fresh juicer juice with many veggies and fruits
Lunch i had a bowl of tomatoe soup with a large veggie juice
Dinner planned in chicken and veggies

Does anyone want to buddy up with me on this?

Im currently 166 lbs and 5'8

ideally id like to be in the 140-145 range (but not in 3 weeks)
