For today’s edition of Dear Mark, I’m answering two questions. First, a new study out is one of the first (and maybe only) to show that acute sugar consumption can reduce the normal cortisol increase we experience in times of stress. Interesting stuff, eh? Find out whether I think this is a good thing, a potentially useful “hack”, or, given our collective tendency to overthink things and embroil ourselves in stress stews, a recipe for disaster. Next, we’ve all heard that weight loss releases stored toxins and environmental pollutants into our bodies, but is there any science that actually shows this is happening in people losing weight? And if we are releasing toxins by losing body fat, does that mean keeping the weight on is actually healthier? Find out down below.
