Hubby's changing diet

Well, Hubby has decided to try a slightly more drastic diet plan to lose some more weight for his contest. Instead of using orovo or some other pill or drink, he's just changing what he eats. My brother gave my sister this diet plan he uses successfully, which basically looks like a low-carb diet with weekends off, so Hubby hopes that it will work for him. It will be a huge diet change though, only 30g of carbs a day. I definitely couldn't do it, I love carbs! In fact the Snickers bar I'm eating right now has more carbs than he can have per day lol. He gets to eat meat, veggies, and some fruit. That's about it. As long as it works, we'll be happy.
