Flavour of the Week

TGIF


  • In non-shocking news, eating more vegetables and fruit lowers risk of stroke. In a meta-analysis of 20 studies, stroke risk decreased by 32% with every 200 grams of fruit consumed each day and 11% with every 200 grams of vegetables consumed each day (Note: 200 g is equivalent to about 2 servings). Why are vegetables and fruit so protective? They improve blood pressure and flow through your small blood vessels, which are significant contributing factors to stroke risk.
  • TGIFCould exercise actually slow down your weight loss? Doubtful. When 17 inactive individuals were enrolled in a six month lifestyle program, they lost less weight than expected and results seemed to be tied to levels of stress hormone. Those with lower cortisol levels, indicating lower levels of stress, were most successful with weight loss.

    Strangely, the authors suggest exercise may have induced an increase in the stress response, so much so that the titled the manuscript, Exercise Can Alter Cortisol Responses in Obese Subjects“, BUT we don’t see how exercise is to blame! While it looks to us that those who were stressed out by lifestyle changes didn’t do as well, there’s nothing to point to increased exercise as the sole culprit here. So, fear not and keep active!
  • Medications for obesity are certainly not a cure-all, nor are they side effect-free. Among those who gained weight while taking Orlistat for weight loss (aka Xenical, or over-the-counter Alli), side effects were most commonly reported as the reason, as well as lack of knowledge about the side effects. Orlistat blocks fat absorption and can cause bloating, abdominal pain and diarrhea when high-fat foods are consumed. Yikes!
