Are Ketones the lesser-known energy source?

Keto diet. Ketones. Good for the brain but bad for the kidneys? An effective weight loss strategy or just another faddy idea? We know it can get confusing which is why Holly has done the research and written an easy-to-read article in Healf all about Ketones and their potential benefits.

Ketones, derived from fats by the liver during low carbohydrate intake or fasting, serve as an alternative energy source, particularly vital for the brain. Their production increases with demand, such as during exercise or overnight fasting.

Due to the brain’s inability to directly utilise fatty acids, ketones play a crucial role as they can cross the blood-brain barrier, providing energy in the absence of glucose. Besides sustaining brain function, ketones offer anti-inflammatory and antioxidant properties, safeguarding cells from oxidative stress.

But being good at switching to this energy source isn’t just from fasting for 12-14 hours of fasting and you’ll need to make sure you’re metabolically flexible o be confident you’ll benefit from this fuel source.

Transitioning into ketosis might result in temporary side effects like keto flu, including gastrointestinal disturbances, reduced energy, and increased hunger.

While the keto diet suits certain populations like those managing blood sugar or epilepsy, it may lack essential nutrients such as fibre found in plant-based foods.

As for supplements – they can offer energy without caffeine-related side effects and may support weight loss, brain health, and athletic performance. However, caution is advised, especially for individuals with medical conditions or those on medication.
