Summary

Story summary

University of Southern Denmark researchers found that lowering methionine and cysteine in mice diets mimics cold exposure and increases energy expenditure by about 20%.
The higher energy use occurred without changes to food intake or activity.
The study, published in eLife, suggests a low-amino-acid diet could promote weight loss and fat burning.
Further research is needed to confirm effects in humans and explore practical applications.
