Hi! I am a 33 year old wife and mother of two children. I am currently at 247. Ugh! I was weighing more but lost a lil bit with plexxus slim! My best friend and I starting a weight loss challenge tomorrow. Does anybody have any tips that may have helped them in their journey to lose weight? Thanks!

Welcome to the forum!
Do you know what food plan you are going to follow? There is a ton of information about many different food plans on this site. Pick a plan that fits in your lifestyle and you can follow long term. I chose calorie counting because it is free and flexible. It allows me to eat almost anything I wanted as long as it fits within my calorie range for the day and there are ton of free apps out there to help you track your food.
Give up the sugary drinks and drink lots and lots of water.
Incorporate some exercise into your weekly routine. You do not have to join an expensive gym try to walk more, use the stairs more, download videos off of YouTube or Hulu.com to work out to. There are a lot of things you can to do with spending a ton of money.
Lastly, if you have a bad meal, a bad day, heck, a bad food week. Do NOT let this be a reason to throw in the towel. Get back on track at the next meal. You can do this!!!
Best of luck to you!

NEmom has some great advice for you there, (most of which I'm following also!), so I'll just chime in with a welcome and all the best to you on your journey!
