YO - YO diet

Have you experienced once that your body weight changing frequently, increasing this week and decreasing another week ? It shows that your diet program is not running very well.
The only thing you can do is : review your everyday menu. May be last night you had large amount of fried potato, today you are starving so much that you don't even touch your favorite melon juice, and tomorrow you have already planned a beer party with your buddy. Wow...this is a no - no, my friend. Gradually you'll be losing your good stamina, while you still have a beautiful dream about competing your body shape with Raquel Weisz ( for girl ) or David Beckham ( for guy ).
So, let's do your diet slowly but sure, please don't do it temperamentally or relying on your mood, but promise to yourself that you will follow a rule you set from the beginning.
