Diet

If you finish a full meal and find yourself raiding the kitchen an hour later, the problem probably isn't your willpower.

You ate a real meal. Not a handful of crackers — an actual plate of food. And yet, sixty minutes later, your stomach is growling again. Sound familiar? Before you blame a lack of discipline, consider this: biology might be running the show.

There are well-understood reasons why some meals satisfy you for hours while others leave you hungry almost immediately. Once you know what's driving the signal, you can make simple changes that actually keep hunger in check.

Decades of low-fat dietary advice are being questioned — and the science behind it is more complicated than you might think.

You've been told for years to choose skim milk, low-fat yogurt, and reduced-fat cheese. But a growing body of research is challenging that long-standing advice. Some large studies now suggest that full-fat dairy may not be the heart villain it was made out to be — and for certain health outcomes, it may even have an edge.

What you eat in the first hour of the day can set the tone for your energy, appetite, and blood sugar for hours to come.

Most people think breakfast is just about not being hungry. But nutrition science tells a different story. The foods you choose in the morning can either steady your blood sugar for hours or send it on a roller coaster that leaves you tired, hungry, and reaching for a snack by 10 a.m. Here is what the research actually says about building the best breakfast for stable blood sugar.

You may be getting enough protein — but are you eating it at the right time to protect your muscle as you age?

Most people think about protein in terms of how much they eat each day. But a growing body of research suggests that when you eat your protein may be just as important for keeping your muscles strong — especially after 40. Here is what the science says and how to put it to work at your next meal.

You might be eating enough calories and still running low on one of the most important nutrients your body needs to function.

Most people assume that if they feel reasonably okay, their diet must be reasonably okay. But protein deficiency does not always announce itself loudly. According to nutrition researchers and public health experts, many adults — especially women over 40 — are quietly falling short on protein in ways that show up slowly, and in places they might never connect to what they eat.

Here is what the science says happens to your body when protein intake drops too low, even when you feel fine on the surface.

Decades of research keep pointing to the same kitchen staple as a powerful ally for a longer, healthier life.

You probably already have a bottle in your kitchen. But you may not realize just how much the science has stacked up in favor of olive oil — not as a trend, but as one of the most consistently studied foods linked to longer life and lower disease risk. Here is what the research actually shows.

The Mediterranean diet gets all the attention — but a Northern European eating pattern is quietly building a serious body of evidence for longer, healthier lives.

You've heard about the Mediterranean diet so many times it practically has its own publicist. But researchers and nutrition scientists are turning their eyes north — to Scandinavia — where a different way of eating is racking up impressive longevity credentials. The Nordic diet focuses on locally grown, seasonal foods from Denmark, Finland, Iceland, Norway, and Sweden, and the science linking it to better health outcomes is growing fast. Here's what the research says and what a Nordic plate actually looks like.

For decades, butter was the villain. New research is complicating that story in surprising ways.

You were told to swap butter for margarine, choose skim milk over whole, and treat cheese like an occasional guilty pleasure. But a growing body of research is challenging those long-held dietary rules — and what scientists are finding about full-fat dairy and heart health may surprise you.

Millions of Americans take vitamin D every day — but many may be reaching for a form that doesn't work as well as they think.

You've probably heard that vitamin D is important. But here's something most people don't know: not all vitamin D supplements are the same. The form on the label matters more than you might expect, and choosing the wrong one could mean your body isn't getting the full benefit you're paying for.

A new study tracked what happens inside the body during a full week without food — and the findings go far deeper than weight loss.

Most people think of fasting as a weight-loss tool, a quick reset, or something monks do. But researchers have now mapped, in remarkable molecular detail, what actually happens inside the human body when someone goes seven full days without eating. The results are surprising — and they raise new questions about what fasting can and cannot do for long-term health.

Most Americans fall far short of their daily fiber needs — and their bodies are paying the price. Here's what the science says happens when you start closing that gap.

You've probably heard that fiber is good for you. But do you know what it actually does inside your body — and how fast it starts working? The answer might surprise you. Changes can begin within days, not months.
