Hello, I'm currently in 2nd year undergrad biomedical sciences in the UK. I have an interest in exercise physiology, nutrition and metabolism but they are not taught directly in my course. Is it a good idea to read science journals to get an overview of what the contemporary scene looks like? It just seems like there is so much info out there, where does one begin so that they can narrow down for when applying to a masters/PhD? I would only do the PhD so that I can work in academia, but it seems like I'm not in a good position to make that choice right now (I will be applying for an undergrad research position for the summer and that's all). Any advice about helping to inform this decision would be great too thanks.
