Carbohydrates are literally in just about everything. There are simple and complex forms of carbohydrates. We need a certain amount of carbohydrates to function. We just need LESS of a good thing. So the phrase low carb diet food, simply connotes those foods that are lower in carbohydrates.

Simple forms of carbohydrates burn faster, so you are hungry again sooner, and for one thing, this leads to cravings and binges. Simple carbohydrates are for instance those that contain sugar. While refined sugar (sucrose) is the worst enemy, there is also fruit sugar (fructose) and milk sugar (lactose).

A low carb diet food would be those that limit all carbohydrates, but especially the simple carbohydrates. Of the simple carbohydrates the only one we really don't need much of to be healthy is sucrose. Particularly, refined white sugar. We would not be wise to eliminate milk (as long as it is skim or low fat), and certainly fruit is always associated with a healthy diet.

Complex carbohydrates are those that are more healthful, such as whole grains and vegetables, which are less processed. It seems the processing is what removes the nutritional value of the foods. Complex carbs take longer to digest and are therefore available to generate energy for a longer period. However, these whole grain foods would also need to be limited due to them being considered high in carbohydrates. In that they are healthy foods, however, small amounts would provide more nutrition than a large amount of processed foods.

The only foods that don't have carbohydrates are meat and fat. Both of these, if eaten in excess can be detrimental to your health. If I eat only meat and fat, I will indeed be on a low carb diet and may lose weight. However, while I may look better, I may die of clogged arteries or a number of other diseases caused by too much meat or fat. No use being a svelte corpse. I'm vain, but not that vain

Pastries are usually made from processed flour, and refined sugar is their main ingredient. Almost as tragic as a life without pastry, is a life without pasta or rice. However, this wonderful food is also one of the main foods that would not ever be considered a low carb food! Eat these very sparingly.

So besides avoiding these major villains, the operable concepts in describing the low carb diet food are limiting or reducing, (not omitting) most carbohydrates; and choosing natural or unprocessed forms of carbohydrates, rather than processed or refined; moderation, as in all things, is key to a low carb diet plan.
