How long does it take for ingested Carbs/Protein/Fat/Sugar etc to have an effect?

I've been watching my diet lately, and read plenty on how carbs are long term energy and fat is short term quick energy etc, but how long does it for those foodstuffs to actually become energy in my body, from mouth to use?  
  
For example, if I eat a high carb food at 1pm, at what time will I feel the benefits of those carbs?  
  
What about water from mouth to hydration?

Actually, it's the complete opposite; fats and proteins are much more energy dense and are metabolised into energy more slowly than carbohydrates.
