Why I start every day with 50g of protein from formulas (+ chocolate caramel recipe)
Every morning, it’s the same thing.
Key Takeaways
Amino acid formulas are the primary source of protein for people living with phenylketonuria (PKU), since natural proteins contain phenylalanine, an amino acid their body cannot metabolize.
Starting the day with protein rather than carbohydrates stabilizes blood sugar, reduces insulin spikes and improves the glycemic response to subsequent meals (second meal effect). This is particularly important for adults with PKU, who are at increased risk of insulin resistance due to a diet that is naturally too high in carbohydrates.
A morning amino acid formula shake (like this chocolate and caramel shake with 50g of protein equivalent) is a concrete strategy for building a solid nutritional foundation from the very start of the day.

Every morning, it’s the same thing. Before coffee, before emails, before anything else, I prepare my amino acid formula for phenylketonuria. 50 grams of protein equivalent, low in carbohydrates. It’s my foundation. It’s what keeps me going.
If you live with phenylketonuria, you know our diet is naturally unbalanced: too many carbohydrates, not enough natural protein. It’s documented. Studies show that adults with PKU consume excessive amounts of carbohydrates and develop problematic nutritional profiles as they age. The risk of insulin resistance is real, and it’s directly linked to that carbohydrate overload in our diet.
But here’s what science also tells us, and this isn’t just about us: starting your day with protein instead of carbohydrates is a complete game changer. A protein-rich breakfast stabilizes blood sugar, reduces insulin spikes and even improves the glycemic response to your next meal. Researchers call it the “second meal effect”: what you eat in the morning directly influences how your body reacts at lunch. And the opposite is also true. A breakfast high in refined carbohydrates causes a rapid blood sugar spike, followed by a crash that brings hunger, irritability and the urge to snack.
For someone with PKU, this is even more critical. We can’t get our protein from eggs or Greek yogurt like everyone else. Our amino acid formulas are our main source. So if I don’t start my day with that, I’m already starting at a deficit. And a protein deficit in the morning, combined with our dependence on starchy foods, is exactly the recipe for the long-term metabolic problems we’re trying to avoid.
So yes, my morning shake is non-negotiable. It’s my nutritional foundation for the day. And as a bonus, the one I’m sharing with you today tastes like chocolate and caramel.
