Is WW really low carb, low fat, high fiber and high protein? I tried living that way once and I was starving all the time!

For sugar, if you aren't avoiding it completely, it's mostly a trade-off like ny biker suggested. If you cut down on sugar, you are naturally cutting down on carbs and calories that can then be used for something else. Sugar is 100% completely devoid of nutrients (unless you are eating raw honey or grade B maple syrup), so why waste calories on it if you are trying to limit your intake? You get so much more bang for your buck if you were to eat a bowl of berries and top it with a little plain yogurt than to eat pre-sweetened strawberry yogurt.

Another pleasant side effect to eliminating all sugar for a period of time is that everything else starts to taste sweeter. After 30 days with zero sugar, I was stunned at how sweet my vanilla Chobani yogurt tasted. It almost made me cringe! It was a huge change because I used to just barely tolerate it because it was the lowest sugar flavor that I could handle (I am not a fan of plain yogurt either)!
