1 the reduction in the average contribution of total fat to
2 dietary energy in the population to about 35 percent."
3
4 Would you accept what is written there?
5 A. Yes, that seems very sensible.
6
7 Q. Including that when the total fat was reduced to levels of
8 less than 10 percent, there was evidence of benefit?
9 A. Yes. I would have to look at that reference but I
10 suspect this was an experimental study and I doubt very
11 much if anybody would persist with a diet containing as
12 little as 10 percent fat in it. I think it would be highly
13 unpalatable. That is one of the major problems of
14 reducing fat intake is loss of palatability.
15
16 Q. In the section on Diet and Obesity, which starts on page
17 140, I think what is written in 6.8.4:
18
19 "Diets relatively high in fat and low in carbohydrate are
20 more energy dense than low fat diets and might therefore be
21 more conducive to the development of obesity."
22
23 I think that is basically what you have got in your
24 statement; is that fair?
25 A. Yes, I would agree with that totally.
26
27 Q. Right, and then in 6.8.5 it says:
28
29 "There is mounting and persuasive evidence that fat has
30 less satiating effect than carbohydrate. Control of energy
31 intake can be described in two main ways: The constraint on
32 meal size is described as satiation while the reluctance to
33 start eating is called satiety. Their determinents are not
34 necessarily identical. In obese women, both hunger and fat
35 content of a meal increase energy intake at that meal but
36 have little effect on the subsequent energy intake. This
37 implies that dietary fat has only weak effects both on
38 satiation (stopping eating) and on satiety (not starting to
39 eat). These relatively weak effects combined with the
40 relatively high density of fat-rich diets to increase the
41 likelihood of eating a diet containing excess energy,
42 so-called passive over-consumption of calories."
43
44 Would you agree with that?
45 A. Yes, that appears to be the case.
46
47 Q. Right. Then in 6.8.7, the middle of the paragraph, there
48 is a sentence:
49
50 "Although it is possible to consume excess energy from any
51 dietary source, it is rendered more likely the richer the
52 diet is in fat. The fat content of the UK diet along with
53 other westernised societies is high."
54
55 You would agree with that?
56 A. Yes.
57
58 Q. Then if we go to page 145. In the summary, this is this
59 chapter about children. It says:
