Eating healthy has been a very big concern since the invention of the eating healthy pyramid created in the 1960. Scientists will argue that eating low carb foods can be dangerous to your health. Each person is different though and what might be too much for one person might not be enough for another.
If you were to look at the list of the low carb foods you would see that they pretty much fit exactly into the US food pyramid that was released by the US department of agriculture except for breads and sugars.
Although many people refute the idea of eating low carb foods no one seems to refute the idea that you should eat oils, fats and sweets. If you were to look at a low carb food pyramid it definitely does not look all that unappealing. Perhaps it is safe to say that the pyramid looks almost the same.
Eating low carb foods is almost similar to how you eat now. The only difference is you watch what types of carbs that you eat. The one big difference is that you do not eat sugar or fatty foods. No snacking unless it is a healthy snack. Although some low carb food diets allow the use of splenda I do not recommend this as there would be no reason to use a substitute.
If you feel yourself starting to slip in energy then you may need to look at what you are in taking. It could be possible that you may be lacking a certain nutrient to help with the lost energy. That can be said for someone who is overweight sometimes it might not be what they are eating just the quantity of the bad food.
Low carb foods are essential if you are looking at losing weight or just maintaining the weight you are at. There are so many diets out there it is probably easier to just make a conscious effort as to what you put in your mouth.
