Description: Segment 1 Dr Durnin introduces the subject and says that he wishes to only deal with energy in the diet and how it affects body composition. A diagram of a body shape is shown and Durnin points out the body's subdivisions and fat deposits. He talks over a chart showing body composition of a male and female and discusses the difference between average body composition of the sexes. Time start: 00:00:00:00 Time end: 00:05:59:11 Length: 00:05:59:11 Segment 2 Durnin says that doctors should measure the fat and fat-free masses in patients. A table showing fat measurements is pictured. Durnin describes techniques of measuring fat. Another table showing fat densities is seen, which can be used to measure fat mass. He discusses another technique of measuring body composition that involves measuring the total body water. A chart showing this technique is seen. Time start: 00:05:59:11 Time end: 00:11:10:00 Length: 00:05:10:14 Segment 3 Durnin describes another technique involving counting the body's potassium content. He says that these methods are all quite expensive, so details a cheaper technique which is to measure the skinfold thickness. He demonstrates some callipers and explains how to work out the fat mass using the skinfold thickness. Time start: 00:11:10:00 Time end: 00:15:53:00 Length: 00:04:43:00 Segment 4 Durnin talks about how fat mass statistics should be gathered to see how they correlate to other illnesses. A table showing megajoule and caloric intakes of recommended diets is shown. Different intakes are shown for men of different occupations. Time start: 00:15:53:00 Time end: 00:22:03:22 Length: 00:06:10:22 Segment 6 Another table showing the energy needed for the growth of infants is shown and Durnin discusses the data. He also mentions that it is important for children to be active. Time start: 00:27:25:00 Time end: 00:29:37:10 Length: 00:02:12:10. Segment 7 Next, Durnin discusses the energy required by pregnant and breast-feeding women. A table is seen, showing the energy required, and Durnin discusses the data. He mentions that pregnant women should not really eat that much more unless they keep active. He says that lactating women do need extra food but that they may also be less active during breastfeeding so should monitor their weight. Durnin concludes the lecture.
