Here’s how they relate to the body:

• Muscles and Brain: These organs readily use ketones for energy.
• Other Organs: Most organs can utilize ketones as an alternative fuel source when glucoseImagine glucose as the tiny batteries powering every cell in your body.

Research Insights: Sugar and Exogenous Ketones

Exogenous ketones and sugar have an inverse relationship. High sugar intake suppresses natural ketone production, while exogenous ketones can increase ketone levels even if carbohydrate intake is moderate.

Research on exogenous ketones is ongoing, with studies suggesting potential benefits for:

• Athletic Performance: May improve endurance and reduce lactic acidLactic acid, often associated with the burning sensation in muscles during intense exercise, is a molecule with diverse roles in the human body. It’s a byproduct of glucose (sugar) metabolism, particularly in situations where oxygen is limited. While its association… Read More buildup during exercise.

Summary and Conclusion

Exogenous ketones offer a shortcut to ketosis, a metabolic state where your body primarily burns fat for fuel. While they show promise for various applications, including athletic performance enhancement and potential therapeutic uses, it’s important to consult with a healthcare professional before using them, especially if you have underlying health conditions.
