AbstractObjectiveTo estimate the daily dietary energy intake for me to maintain a constant body weight. How hard can it be?DesignVery introspective study.SettingAt home. In lockdown. (Except every Tuesday afternoon and Saturday morning, when I went for a run.)ParticipantsMe. n=1.Main outcome measuresMy weight, measured each day.ResultsSleeping, I shed about a kilogram each night (1.07 (SD 0.25) kg). Running 5 km, I shed about half a kilogram (0.57 (SD 0.15) kg). My daily equilibrium energy intake is about 10 000 kJ (10 286 (SD 201) kJ). Every kJ above (or below) 10 000 kJ adds (or subtracts) about 40 mg (35.4 (SD 3.2) mg).ConclusionsBody weight data show persistent variability, even when the screws of control are tightened and tightened.

Ad Libitum

Forty crossbred lambs (20 rams, 20 ewes) were penned in two groups (equal numbers of each sex) and fed a pelleted ration either ad libitum (H) or 70% of expected ad libitum intake (70% H). Ten lambs (5 rams, 5 ewes) from both groups (H and 70% H) were slaughtered after 40 days on feed while the remaining lambs were slaughtered after 61 days on feed. All lambs were measured for carcass leanness using an EMME machine immediately prior to slaughter. The offal components were weighed fresh and the alimentary tract was emptied of digesta. One side of each carcass was broken into four cuts (leg, loin, rib, shoulder) which were further separated into fat, muscle and bone. EMME numbers only marginally increased the amount of explained variation in the prediction of lean weight over that provided by liveweight alone. Growth coefficients between sexes and intake groups (H, 70% H) for the offal components relative to empty body weight were homogeneous, indicating that sex and dietary energy intake did not affect the relative growth of the offal components. Ram lambs had heavier heads and smaller intestines than ewe lambs, but contained less caul and mesenteric fat than ewe lambs at the same empty body weight. Lambs fed H had a greater weight of pelt, liver and caul fat, but had a lower warm carcass weight and less mesenteric fat than lambs fed 70% H at the same empty body weight. Growth coefficients between sexes and intake groups for the carcass tissues relative to physically separated tissue weights (muscle, bone, fat) were homogeneous, which indicated that sex and intake did not affect the relative growth of the carcass tissues. Ram lamb carcasses had a greater weight of muscle in the shoulder and less muscle in the leg than ewe lamb carcasses at the same carcass muscle weight. Dietary energy intake had small but statistically significant effects on carcass muscle distribution. Lambs fed 70% H produced carcasses with proportionally more muscle in the leg and less muscle in the loin and shoulder than lambs fed H at the same carcass muscle weight. Sex and dietary energy intake had minor effects on carcass bone and fat distribution. Key words: Lambs, carcass, offal, fat, EMME

The rationale for employing a nonlinear iterative least-squares technique for fitting the well-known power function to oxygen consumption–body weight data is set forth. Twenty-six sets of routine or standard metabolism data from six authors were used to demonstrate the relative merits of two methods of calculating parameter values for the power function. The conclusion was reached that if accuracy in predicting oxygen consumption over a wide range of values of body weight is desired, an iterative curve fitting method may be superior to the much used technique of performing a linear regression on logarithmically transformed data.
