Oral temperatures correlated with sleeping and 24-h metabolic rates adjusted for differences in body size, body composition, and age.

Understanding the correlation between body temperature and metabolic rate can aid in metabolic health assessments.

Federal dietary advice has shifted from 'decrease consumption of meat' to 'have two or three (daily) servings' under pressure from meat producers.

Practitioners should consider how dietary guidelines may be influenced by industry interests.

Lowering dietary fat has led to an underestimation of the potential role of dietary composition in promoting reductions in energy intake and weight loss.

Practitioners should consider the role of dietary composition beyond just fat reduction in weight loss strategies.

Higher genetically determined BMI is not associated with insulin secretion.

This suggests that BMI may not directly influence insulin secretion, which could inform treatment approaches.

Sleep stages are associated with only small differences in energy metabolism.

While sleep stages affect metabolism, their impact is limited, suggesting other factors may be more significant.

Significant disproportionality for semaglutide remained in patients with coreported use of antidepressants and benzodiazepines.

Clinicians should consider the interaction of semaglutide with antidepressants and benzodiazepines when assessing risk.

Randomised controlled trials have not provided conclusive evidence that physical activity started during adulthood extends lifespan.

Caution should be exercised in claiming lifespan benefits from adult physical activity alone.

The health-related benefits of exercise have not yet translated into a proven causal relationship with longevity.

While exercise is beneficial, its direct impact on longevity remains unproven.

Using respiratory chambers for these studies should improve understanding of body weight regulation.

This suggests that improved measurement techniques can lead to better strategies for managing body weight.

Steps need to be taken to control the effects of food-industry sponsorship.

Practitioners should implement measures to reduce bias from sponsorship.

Foods with lower stated energy contents contained higher measured energy contents than stated, while foods with higher stated energy contents contained lower measured energy contents.

Practitioners should consider that lower calorie items may be more likely to be underestimated in their energy content.

NEAT is likely to serve as a crucial thermoregulatory switch between energy storage and dissipation that is biologically regulated and influenced by the environment.

Understanding NEAT can help in developing interventions for obesity prevention and treatment.

There was no evidence of a decrease in 24-h energy expenditure on a high-fat diet compared with a high-carbohydrate diet.

High-fat diets do not lead to reduced energy expenditure compared to high-carbohydrate diets in this population.

Moderate duration exercise has little impact on 24-h fat oxidation.

Short-duration exercise may not significantly enhance overall fat oxidation throughout the day.

Obesity prevalence is projected to grow by 40% in the next decade.

Practitioners should prepare for increased obesity-related health issues in the coming decade.

The incidence of obesity-related glomerulopathy has increased tenfold in recent years.

Clinicians should be aware of the rising rates of kidney issues related to obesity.

Mathematical modeling of human energy regulation and body weight change has reached a level of sophistication for accurate predictions.

Practitioners can utilize advanced mathematical models to better understand energy regulation in their clients.

Mathematical models can guide future experimental research in energy regulation.

Practitioners and researchers can use these models to inform and design future studies on energy regulation.

The doubly labeled water method can provide accurate and reasonably precise information on carbon dioxide production, total body water, and water intake in free-living humans and many small animals.

This method can be reliably used to assess energy expenditure and hydration status in various populations.

Total energy expenditure can be calculated from carbon dioxide production with little loss of precision.

Practitioners can use carbon dioxide production measurements to estimate energy expenditure reliably.

Metabolizable energy intake can be predicted, but this prediction is unlikely to be accurate and precise unless the subject is in approximate energy balance.

Practitioners should be cautious when predicting metabolizable energy intake, especially if energy balance is not confirmed.

All measures of TEE were significantly correlated.

Practitioners can rely on the correlation between different TEE measurement methods for consistency.

Weight gain of 10% was associated with significant increases in dietTEE and isotopeTEE but not chamberTEE.

Practitioners should note that weight changes can significantly affect energy expenditure measurements.

There is a lack of nutrition- and lifestyle-related curricular requirements for professional medical certification.

Curricula should be revised to include nutrition and lifestyle education.
