I never got why people shun carbs. Despite the fact that carbs can easily lead to overeating since they aren't filling, carbs alone don't lead to weight gain, although they can cause water retention/bloat. It's overall calories that matter.
Giuliana's make up artist has a blog and it is pretty interesting. She posts a lot about her weight and food intake (she eats a lot of eggs, vegetables, and if she eats "junk" food she'll just have a few bites of it), she takes a lot of supplements (vitamins and senna tea). Nothing unusual but it's refreshing to see somebody be honest. Sometimes she posts pics of her friend's scale and I wonder if it's G's.
It's the easiest to cut out without feeling like crap/nutrient deprived. You don't need 300g of carbs to survive also, the water retention is a mind fuck
