Dietary intake and tissue concentration of fatty acids in omnivore, vegetarian and diabetic pregnancy
V. Lakin,Paul Haggarty,David Abramovich,J Ashton,C.F. Moffat,Geraldine McNeill,P.J. Danielian,D. A. Grubb +7 more
TL;DR: In the vegetarian mothers, the PUFA profiles in the maternal erythrocytes, placenta and cord are consistent with an elevation in the rate ofLCPUFA synthesis in order to make up the relative deficit in LCPUFA intake, however, it may be that the higher level of desaturase activity is not able to overcome the dietary deficit of 22-6 n-3 and 22: 6 n-6.

The influence of exercise on the energy requirements of adult males in the UK
TL;DR: The results indicate that the recent Department of Health (1991) reference values for energy may underestimate the expenditure of a significant proportion of the UK population largely because the energy costs of activity used in the report to calculate expenditure do not accurately reflect those achieved during active leisure in individuals who take regular exercise.
Energy expenditure during heavy work and its interaction with body weight
Paul Haggarty,Mauro E. Valencia,Geraldine McNeill,N L Gonzales,S Y Moya,A Pinelli,Luis Quihui,Maria del Socorro Saucedo,Julian Esparza,J Ashton,Eric Milne,W. P. T. James +11 more
TL;DR: It may be necessary to take account of body weight when using the BMR-multiple approach to estimate energy requirements at low body weights to avoid errors which could be interpreted as metabolic ‘adaptation’.
Estimation of energy expenditure in free-living red deer (Cervus elaphus) with the doubly-labelled water method
Paul Haggarty,J. J. Robinson,J Ashton,Eric Milne,Clare Lesley Adam,C E Kyle,S. L. Christie,A. J. Midwood +7 more
TL;DR: Energy expenditure was estimated using the doubly-labelled water (DLW) method in summer in five free-living adult, non-pregnant,non-lactating, red deer hinds on lowland pasture under typical farming conditions.
Free and esterified fatty acid and cholesterol synthesis in adult males and its effect on the doubly-labelled water method.
TL;DR: The results, obtained in subjects typically consuming a diet with a lower fat and cholesterol content that the typical Western diet, suggest that the DLW method is unlikely to be affected by fatty acid and cholesterol synthesis in subjects in energy balance consuming a typicalWestern diet.
