The Truth About Fasting, Leaky Gut & Blood Sugar

Feeling tired, bloated, or struggling with cravings? In this episode of The Health Review, host Emily Rose Adams sits down with UK Registered Nutritionist May Simpkin (MSc, MBANT) to unpack the science and strategy behind fasting, leaky gut, and blood sugar balance.

takeaways

  1. Nutritionist Mae Simpkin discussed why she favours 16:8 intermittent fasting over longer water fasts, framing extended fasting as a potential stressor on the body.

  2. The conversation explored 'leaky gut' — describing the finger-like projections and tight junctions of the gut lining, and how larger undigested particles passing into the blood can cause problems.

  3. Mae emphasised feeding gut bacteria with fibre (soluble fibre, prebiotic foods like onions, garlic and asparagus) and introducing live bacteria through foods such as live probiotic yoghurt.

  4. Bone health was said to peak by the late 20s, with a discussion of calcium sources including dark green vegetables, sesame seeds/tahini, pulses, legumes, nuts and dairy.

  5. Balancing blood sugar was linked to combining carbohydrates with protein, healthy fats and fibre to slow sugar release and avoid the 'blood sugar roller coaster'.

  6. Mae shared practical habits: planning meals, shopping thoughtfully, using frozen foods, 'food assembly' rather than complex cooking, and saving leftovers.
