The Course of the Study
A study was published in the British Journal of Nutrition that states that habitually having coffee before breakfast is likely to impair one’s metabolism. The research was conducted by Henry Smith and his co-authors and researchers at the University of Bath’s Centre for Nutrition, Exercise & Metabolism. Twenty-nine healthy men and women took part in the experiment to learn the effects of insufficient sleep and morning java on the metabolism. The three steps of the study tested the metabolic reaction to:
- A full night’s sleep followed by a sugary drink that was meant to simulate breakfast
- A disrupted night’s sleep followed by the same sugary beverage
- A disturbed night’s sleep was immediately followed by black coffee and the same sugary drink 30 minutes later.
The Right Time to Have Coffee
Throughout the course of the research, the participants’ mood, appetite, sleep quality, height, weight, and waist circumference were being observed. Additionally, blood samples were taken after each test to measure the effects on one’s insulin sensitivity and metabolic health. The study indicated that having strong coffee after insufficient sleep greatly increased the blood glucose response meaning that doing this habitually could lead to reduced insulin sensitivity over a prolonged period. Further and more extensive studies are needed to come to more conclusive results. However, for now, the recommendation is to have caffeinated beverages after breakfast, try to ensure quality sleep, and indulge in healthy levels of exercise and physical activity to reap the benefits and avoid long-term side effects on one’s metabolism.
