Now when making a lifestyle change (really exercising and dieting but we 'diet' all wrong) the beginning is one of the hardest parts. It's always hard to start to change. Once something becomes a routine it is infinitely easier (not that we want to get into learnt behavior and such). However, the beginning of a 'weight loss campaign' is also the easiest time to lose weight. The first week (or two sometimes) you usually shed the most weight, the fastest, with the least amount of true effort. People need to remember, really being in shape is just discipline and work.
