Rounding off our Back to Basics mini-series, this episode is all about fiber—the powerhouse nutrient for gut health and satiety. I’ll break down the best fiber sources, expose some sneaky low-fiber foods (yes, even the salad bar could be letting you down!), and share practical, easy-to-follow tips for gradually increasing your intake without any digestive discomfort. Tune in for simple ways to hit your fiber goal and get it into every meal.

Quotes
“The fiber goal for women is going to be 25 grams or more fiber per day. And for men, 38 grams or more per day.”
“When you don't have enough fiber, you cannot reach satiety. So you need there to be some bulk to your meals to have the stretch receptors in your stomach activated.”
“We actually have more bacteria than we have human cells. They need fiber to live on and to thrive.”
“Every meal or snack you have, there has got to be some fiber.”
“People will tell me, ‘Well I have these big bowls of salad’, and the reality is two cups of salad may be up to two grams of fiber. It's not a lot.”
“Remember, every time you increase fiber too abruptly, you can actually get a lot of stomach discomfort, gas, bloating, and a lot of problems. So find where you are and then just go up by a few grams.”
