Carbs or fat or whatever it all depends on the individual system.

My daughter has ibs (irritable bowel syndrome) one of a number of auto-immune diseases which can also mimic each other & she can't eat sugary foods, potato, sweet potato, corn, pasta, rice or bread of any sort if she does her system just doesn't work & aside from being sick she loses weight (to dangerously low levels) a friend on the other hand who also has ibs can't eat cheeses etc which my daughter can & does eat in massive abundance.

Other people have celiacs disease so can't eat gluten etc etc etc so whether carbds or fat or anything else is good or bad depends on your system & any deficiancies.

You need a certain amount of both in your diet. You can cut back on fats. You can eat fat free, or reduced fat food if thats what you prefer. But as far as carbs go, you need to eat carbs, because thats where you get energy. You can cut back on carbs. Like only eat it 2-3 a week, but I don't suggest cutting them out of your diet. My friend cut carbs from her diet completely and she lost all of her energy and started getting sick alot.

It really depends on the person, but if you read a book (or you can read it online) about the "atkins" diet, which limits carbs, it really really makes sense. Not only does it make you lose weight, but it levels out blood sugar, gives you more energy and has a lot of other health benefits.
Carbs is where you get your energy, but if you are trying to lose weight and you cut carbs out, then your body will use its stored fat for energy. Plus, a lot of carbs are so very bad for you anyway. And sugar is soooo very bad for you.
i always wondered about it and how it worked and why it didn't raise cholesterol and what not, but after I read about it, it all makes sense.

But, like I said it may not work for everyone. I just started it four days ago and if you like, I will let you know how it goes.

Oh and as far as the fat thing goes, your body needs "good" fat. It cancels out the bad vitamins that we eat and have in our bodies. A completely nonfat diet is very unhealthy.

There are carbs in almost all foods except meat, so unless you cut out fruit, vegetables, all cheeses, all nuts & beans you will still get carbs even if you doi not eat bread, grains, cereals, potatoes, sweet potatoes & pasta, so I wouldn't worry.

If you have an auto-immune disease like irritable bowel syndrome then eating starches & sugar (inc for many people potato, sweet potato, corn, bread, pasta, cereal etc) may cause you to lose weight where as avoiding them will lead you to gain weight. My daughter being a prime example of this.

Fats are also in lots of foods, dairy, nuts, meats etc so again avoiding them all is basically impossible.
