French Biochemist Reveals Eight Unexpected Factors That Affect Glucose Levels

French biochemist Jessie Inchauspe, widely known on social media as the Glucose Goddess, has highlighted eight surprising factors that influence blood glucose beyond diet alone.

She shared her insights in an Instagram post on October 23. She stressed that sleep, stress, hormones, and lifestyle habits all play a role in regulating glucose.

1. Meal Timing Matters

Inchauspe noted that eating after 8 pm can increase glucose and insulin levels by 20–40%. This is in comparison with consuming the same meal earlier in the day.
“Our bodies handle glucose better in the morning. At night, insulin sensitivity naturally declines, meaning sugar stays longer in the bloodstream,” she explained.

2. The Role of Sleep

Short or fragmented sleep can reduce insulin sensitivity by up to 25%, according to studies cited by Inchauspe. She warned that even a single poor night’s sleep can lead to larger glucose spikes from the same meal.

3. Light Exposure

Exposure to light during sleep, such as from phones or devices, can disrupt the body’s internal clock. This disruption may raise glucose levels the following day. Morning light, on the other hand, helps regulate metabolism and insulin function.

4. Stress and Anxiety

Stress triggers cortisol and adrenaline, prompting the liver to release extra glucose. Similarly, eating while distracted or anxious keeps the body in a ‘fight or flight’ mode. This slows digestion and reduces insulin efficiency.

5. Hormones

Glucose and insulin responses fluctuate with the menstrual cycle. In the luteal phase, rising progesterone can slightly impair insulin function, causing higher glucose levels or cravings.

6. Hydration and Magnesium

Adequate water intake and sufficient magnesium improve fasting glucose. Dehydration concentrates blood sugar, while magnesium assists insulin in regulating glucose.

7. Regular Movement

Exercise lowers fasting glucose and promotes stable levels throughout the day. Muscles absorb glucose without insulin, and a single workout can increase insulin sensitivity for up to 48 hours.

8. Mindful Eating

Being present while eating, avoiding distractions, and reducing stress during meals helps the body process glucose more effectively.

Inchauspe concluded that perfect glucose control is unrealistic. However, understanding these factors can help people better manage their metabolism and overall health.
