lol Jay could help you on this, but ill give it a go. Problem with places like weight watchers and that is that whilst their methods may work, they dont leave you feeling good about your self as body composition is still left undesirable. What Id suggest is eat a meal the size of your hand every 2 hours, basically this will get your metabolism working harder, and take some caffein tablets but not after 6pm. Drink 4 glasses of cranberry juice drink plenty of water and stay clear of carbs after 3pm
If you can when at home 3 times a week go for a jog and do basic exercises like push ups and situp and stretching. Push up bars work wonders to your body composition
Jay is spot on mate mate! Especially about the meals if you have smaller regular meals you will feel less hungry and also not snack! But as jay said its all about the metabolism working harder so the food isnt just laying there and makes it harder to break down. I find if you can drink as much water as possible the better, i kno it sounds obvious but it works as it flushes out all the nasty toxins etc! Lastly any excercise is great for you! If your not a keen runner dont worry about it a medium paced walk or even a little jog is just as good! If you start off with small changes i.e cut down on the crap gradually you will prob find a big difference. Sorry if i have just rambled lol.
