Lectures in Nutrition How Fat Cells Work  

Interested in losing those extra festive season pounds you piled on? Then you need to be concerned about your calorie intake...

Most problematical calorie sources are Carbohydrates and Fats (lipids)...

For every gram of fat you digest you are taking in 9 kilocalories - if your body doesn't need to burn it right now, it will be stored as fat...

For every gram of carbohydrate you digest you are taking in 4 kilocalories - if your body doesn't need to burn it right now, it will be stored as fat...

The Kilocalorie is referred to as calorie...



Protein is more likely to be  involved in storing fat it is taken excessively, generally protein just uses the calories stored in fats and carbohydrates as an energy source in order to make new protein (muscle and other lean tissue) and carry our repairs on damaged tissue... However if your body doesn't have any intake of  fat or carbohydrate it can use protein from your muscles as an energy source and that includes protein from your own muscle...

With lower levels of exercise for prolonged periods (for example, brisk walking)  fat is utilised to provide energy. The heart rate (and thus oxygen uptake) burns fat most efficiently at a heart rate of (220-your age) x 70%Under these conditions, oxygen is used and the carbohydrate goes through both the Embden-Meyerhoff pathway of anaerobic metabolism.


For those people who feel that The Atkins Diet is the best thing since 'sliced bread' they may like to read a book which was, probably, the first reference to a low carb diet in history... It is written by William Banting and published in its fourth edition in 1869 it concerns itself to the ailment of Corpulence (obesity).

It must be remembered at this stage however that this book was not really aimed at the masses living in Dickensian Britain as many millions of poor people had such meagre diets at that time and many, especially on the streets of London relied upon a main diet of carbohydrates for mere sustenance... some of the poorest had diets that consisted of almost daily consumption of Bread & Dripping and Tea; tea being preferred in isolation if a choice had to be made...

For further information on The London Poor please refer to Henry Mayhew's wonderful excellent research to be found in his text -  

London Labour and the London Poor, 1861
