Hot chocolate is arguably the ultimate cosy drink with its sweet, comforting and rich flavour. Each cup of cafe or store-bought hot chocolate will quickly tip you out of ketosis with its high sugar content. The Fast 800’s co-founder, Dr Michael Mosley, is a self-confessed chocoholic, so it felt only natural to create The Fast 800 Keto Hot Chocolate to satisfy sweet tooths while continuing to support their metabolic goals.

This warming drink is ideal for those following a keto diet. While it can be stressful to know what you can and can’t drink on a keto diet, rest assured that this delicious drink won’t tip you out of ketosis and will support your lifestyle.

This hot chocolate blend contains a bioavailable hydrolysed collagen, which is easy for your body to absorb and use. Collagen is the most abundant protein in our body, but production in the body slows with age. Supplementation can support the health of joints, skin, and hair, and aid muscle retention. As collagen production starts to decline from about age 25, it’s important to supplement your supply, and it’s an added bonus that this collagen-rich hot chocolate is convenient and delicious!
