Well done to all of you lifestyle changers, I don't say dieters because I think that diets are a fad and wont last, a lifestyle change will last , and you WILL reap the benefits. My tips above all else are :
1/ Never skip breakfast, if you don't have breakfast then start to do so. It is a great kick start to your daily metabolism.
2/Drink at least 2 litres of water a day, on top of any other drinks you may consume.
3/Try not to eat before going to bed.
4/Have healthy snacks around the house: dried fruit, fresh fruit, nuts, seeds, cereal bars etc
5/ Look to put more "good" food stuff in, rather than looking at all the "bad" stuff you need to take out. It's almost reverse psychology but once you start to feel the benefits, and you WILL, you'll naturally put more of what's best for you in, and reduce on the junk.
6/Allow yourself junk food if you love it, just in moderation.
Good luck and remember slow progress is better than no progress
