Diabetes: Avoid eating sweets and starchy food before bed – causes blood sugar to ‘crash’

“You can also use a glucometer to check your fasting blood glucose, which ideally should be in the mid- to high-80s, and at least between 80 and 100.

“Eat a well-balanced diet consisting mostly of vegetables, and quality proteins (eggs, fish, meat, tofu), plenty of fibre and fats.”

She added: “Never eat sugary or high carb foods without some fibre, fat, or protein. These added factors slow down the rate at which glucose is absorbed into the bloodstream and help prevent insulin surges.

“Don’t rely on caffeine and sugary snacks to get you through your work day; instead, bring along high-protein, healthy-fat lunch and snacks with minimal carbs.”
