When losing weight, despite the fact that it may cost you a little bit more money, I would suggest buying yourself new jeans when you lose a size or in some cases 2.  Throw away your old jeans.  This will motivate you to keep the new weight off. After all, if you gain it back, you won’t have any old clothes as a backup plan, which will make you spend more money!  As for me, I’m cheap.  So I wait 3 sizes, or 20-30 pounds depending on how much my focus lies with fat and how much of it would be more of water weight.  But that is definitely not recommended.  It’s one of those things follow what I say, not what I do.  And in terms of sizes, going from size 12 to size 10 is considered 1 size in my world, not from 12 to 11.  Now when you get down to the smaller sizes, it’s more like from 2 to 1 or 1 to 0 or 0 to 00.  But above that, it is 2 numbers.  But honestly, people are more motivated by money or the loss thereof.  So keep yourself motivated by throwing away old clothes as you go or donating them if you want to help others.
