Hutchins K, Betts J, Thompson D, Hengist A, Gonzalez J
Am J Clin Nutr . 2025 Feb; PMID: 40021059
Background: Continuous glucose monitors (CGM) are used to characterize postprandial glycemia, yet no study has directly tested how different test foods/beverages alter CGM accuracy. Objectives: Assess glycemic responses to test...

Betts J, Bowden Davies K, Smith H, Hawley J
Exp Physiol . 2025 Jan; PMID: 39888208
Metabolic regulation is essential for maintaining homeostasis in response to fluctuating dietary nutrient availability. In this review, we explore how metabolic health can be affected by the temporal alignment between...

Beattie C, Thomas M, Borislavova B, Smith H, Ambler M, White P, et al.
BMJ Open . 2024 Nov; 14(11):e086540. PMID: 39581721
Introduction: Over half of patients who spend >48 hours in the intensive care unit (ICU) are fed via a nasogastric (NG) tube. Current guidance recommends continuous delivery of feed throughout...

Smith H, Betts J
Proc Nutr Soc . 2024 Nov; :1-5. PMID: 39555585
Endogenous biological rhythms synchronise human physiology with daily cycles of light-dark, wake-sleep and feeding-fasting. Proper circadian alignment is crucial for physiological function, reflected in the rhythmic expression of molecular clock...

Ijaz A, Collins A, Moreno-Cabanas A, Bradshaw L, Hutchins K, Betts J, et al.
Int J Sport Nutr Exerc Metab . 2024 Sep; 35(1):12-23. PMID: 39332815
There is little evidence that body size alters exogenous glucose oxidation rates during exercise. This study assessed whether larger people oxidize more exogenous glucose during exercise than smaller people. Fifteen...

Gonzalez J, Lolli L, Veasey R, Rumbold P, Betts J, Atkinson G, et al.
Eur J Nutr . 2024 Sep; 63(8):2897-2909. PMID: 39231870
Background: Following consumption of a meal, circulating glucose concentrations can rise and then fall briefly below the basal/fasting concentrations. This phenomenon is known as reactive hypoglycaemia but to date no...

Cell Rep Med . 2024 Aug; 5(8):101667. PMID: 39106867
Restricted sugar and ketogenic diets can alter energy balance/metabolism, but decreased energy intake may be compensated by reduced expenditure. In healthy adults, randomization to restricting free sugars or overall carbohydrates...

Davies S, Perkin O, Betts J, Gonzalez J, Hewison M, Jenkinson C, et al.
J Physiol . 2024 Aug; 602(17):4157-4170. PMID: 39097829
The effect of acute exercise on circulating concentrations of vitamin D metabolites is unclear. To address this knowledge gap, we examined the effect of a bout of treadmill-based exercise versus...
