Let's talk about just how big this problem really is — because the stats are staggering.

In 2022, 1 in 8 people globally were diagnosed with obesity. Adult obesity has more than doubled since 1990. Adolescent obesity? It's quadrupled.

Here in the U.S., the numbers are even more alarming: more than 2 in 5 adults (42.4%) have obesity, and 1 in 11 adults have severe obesity. Among children and adolescents aged 2-19, nearly 1 in 5 (19.3%) have obesity, and 6.1% have severe obesity. If you include the overweight category, nearly 75% of U.S. adults are affected.

And here's the kicker: despite decades of education about healthy eating and exercise, the numbers keep climbing. In fact, no country in the world has made significant progress in tackling obesity over the last 40 years.

So what are we doing wrong? Why is this epidemic continuing to grow despite everything we know?

That's the question we need to answer — and it starts with understanding that this isn't about individual failure. It's systemic. It's biological. It's environmental. And it requires a complete shift in how we approach prevention and treatment.

In the next episode, we'll dive into the consequences of not addressing obesity — and why taking action matters now more than ever.

In this episode, let's talk about stress eating, also called emotional eating. It's when you eat in response to emotions rather than physical hunger. It's usually a way to cope with stress, anxiety, sadness, boredom, or even excitement.

Why does it happen? Stress triggers the hormone cortisol in our body, which increases appetite and cravings, especially for sugary, salty, or high-fat foods. Eating releases dopamine, the brain's feel-good chemical, giving temporary relief from emotional discomfort. Once your brain recognizes this pattern and associates food with pleasure and comfort, it forms a habit loop. Signs you might be stress eating include eating suddenly and urgently without much thought, craving specific comfort foods rather than balanced meals, eating even when you're full, and feeling guilt, regret, or sluggishness afterward.

How do you break the cycle? First, pause and check for hunger signals. Ask yourself: am I really hungry or am I seeking comfort? Identify your triggers by keeping a journal of what situations or emotions spark eating urges. For example, many women crave sugar during the premenstrual phase. Then find alternative coping mechanisms like taking a walk, deep breathing, stretching, listening to music, or talking to a friend. Managing stress proactively through regular exercise, good sleep, and mindfulness practices like meditation or prayer reduces cortisol levels over time. Creating a supportive food environment also helps: keep tempting trigger foods out of immediate reach and stock easy, healthy snacks like dates, nuts, or dark chocolate instead of cookies.

The bottom line: think of your emotional hunger like a smoke alarm. It's a signal that something's off emotionally, and food is just one possible fire extinguisher. You can choose other options that won't leave a mess behind or feelings of guilt afterward.

In this episode, I'm talking about glycemic index. The glycemic index is a system that ranks carbohydrate foods based on how quickly they raise your blood sugar levels after being eaten. The scale typically ranges from 0 to 100, with higher values indicating foods that cause a rapid increase in blood glucose.

Imagine your body as a fireplace and food as the logs you throw in it. The glycemic index tells you how quickly the food will burn. High glycemic index foods (70 or above) cause a rapid spike in blood glucose. They're often low in fiber and quickly digested and absorbed. This food burns like dry kindling: quick energy, but the flames die down fast, which means you'll feel hungry or tired sooner. Examples include white bread, sodas, sweetened coffees and teas, sugary snacks, and many processed foods. Medium glycemic index foods (56 to 69) cause a moderate increase in blood glucose, burning at a steady pace. Examples include whole wheat products, sweet potatoes, sweet corn, bananas, and some types of rice. Low glycemic index foods (55 or less) cause a slow, gradual increase in blood glucose. Examples include most fruits, vegetables, legumes, whole grains, apples, and oats.

Why does it matter? Stable blood sugar equals steady energy and fewer crashes. Low glycemic index foods help maintain steady blood sugar levels, leading to better satiety and easier weight management because they keep you fuller for longer. Diets rich in low glycemic index foods are also better for your heart, helping manage cholesterol levels and reduce the risk of cardiovascular disease. Factors that influence the glycemic index include the type of carbohydrate, fiber content, preparation and cooking methods (al dente pasta has a lower GI than overcooked pasta), ripeness of fruits (ripe bananas have a higher GI than unripe bananas), and fat and protein content (combining carbs with fat or protein slows digestion and lowers the GI).

The bottom line: understanding the glycemic index can help you make informed choices about your diet, particularly if you're managing blood sugar levels or optimizing energy throughout the day. Our goal is to mostly consume low or moderate GI foods, or combine high GI foods with fat and protein to slow digestion.
