There’s nothing to fix, the balance of BCAAs in Huel products is ideal and we have other Hueligans who want a higher amount of BCAAs.
The study you cited looked at varying BCAAs as a ratio to other amino acids in mice. The macronutrient ratio used is not similar to any Huel product “18% total protein, 64% carbohydrate, 18% fat”.
When you look at the diets of the mice one possible conclusion is that an imbalance of BCAAs in a highly processed Western diet could contribute to overeating and the authors suggest this is because the mice are trying to get enough non-BCAAs in their diet. Such a diet could be achieved in humans is by eating a poor diet and supplementing with BCAAs.
This is the complete opposite of what was reported in the paper. “Despite no increase in hepatic mTOR activation” and “Our results suggest that the negative health and lifespan costs of long-term high BCAA: non-BCAA diets are a consequence of hyperphagia and obesity”. The affect on mice lifespan was due to overeating and calorie excess.
I haven’t seen a study which has shown these results in humans or with a healthier diet. If you look at the amino acid profile of Huel: https://uk.huel.com/pages/the-huel-powder-formula-explained#protein or even just the ingredients that make it up you will see that the study isn’t relevant to Huel.
There are also several benefits to BCAAs such as muscle anabolism (building muscle). Let me know if you have anymore questions.
