The short answer here is "no", it doesn't have to be difficult. In fact, as with most things in life, the simplest approach is usually the best and most effective way to go. The same rule applies when it comes to weight loss. The reason for this is simple: The easier something is, the more likely we are to stick with it.
So to rephrase, the keys to weight loss are SIMPLICITY and CONSISTENCY. If you are consistent with your efforts, you don't have to worry about how long something will take because you know that you will get there eventually.
