Same lunch, 369 fewer calories. The difference was the crunch

Today’s letter

The chew test that may leave you fuller on the same lunch

A list went around last month. Someone had checked a dozen fast food chains for ultra-processed ingredients, and exactly one of them came back clean. My inbox filled up with it for a week, and every woman who forwarded it wanted the same thing: a list of what she is still allowed to buy.

I used to think the ingredient list was the whole answer. For eleven minutes one afternoon I stood in a store comparing the backs of two boxes of crackers, hunting for the emulsifier. One box went back on the shelf and I felt good about myself. Then I got home, ate most of the other box standing at the counter in about four minutes, and never once felt full.

“Why am I still hungry?”

You are not careless about this. Labels get read in your house. You are the woman who checks the back of a package while the store closes around her, who switched to the yogurt with five ingredients, who packs a lunch instead of buying one. Nobody has ever accused you of not trying. Then an hour after a decent lunch… you are back in the kitchen looking for something else.

You did what the advice said. Clean up the ingredient list, swap the bread and the cereal and the crackers, and the hunger settles down on its own. When it did not settle, there was one explanation left… and it was you. Your appetite. Something broken in your willpower. That is where a lot of women land, and for years I helped push them there.

Here’s what gets me.

None of it was your fault. You were handed one half of the answer, and then blamed for the half nobody told you about.

Hormones, genetics, stress, aging…

They’re all blamed for hair loss.

New research shows the “cause” doesn’t matter.

Yet what does is the bottleneck that stops hair from growing: Clogged follicles.

See, when hair follicles are clogged with dead skin, hardened oils, and other gunk…

No new hair can grow.

Yet once you clear this “Follicle Clog”…

Your hair’s thickness, health, and volume surges back to life.

In fact, a “Follicle Clog” clearing technique we developed is linked to a 32% reduction in hair loss.

Terri, who tried it, said: “There’s way less hair in the drain. It’s actually staying on my head.”

If you’ve struggled with thinning hair for years… and would love to see baby hairs growing again…

Let me show you how I know. Not with my opinion, but with a study built to test this exact question.

Researchers at Wageningen University in the Netherlands fed forty-one healthy adults two different diets, two weeks on each, with a break in between. Both diets were made almost entirely of ultra-processed food. Same aisle, same packaging, same ingredient lists you would flinch at.

The one thing that changed was texture. Soft menus used things like mashed potato, sweetened yogurt, and cheese on a soft white bun. Firmer menus used fried noodles with beef and cabbage, and cheese on a dense multigrain bun. Portion sizes, calories served, and how much people liked the food were all matched. Everybody was told to eat as much as they wanted, until they were full, and nobody was counting anything.

What they found

Wageningen University, 2026. Forde et al., The American Journal of Clinical Nutrition.

The soft menu (they ate more)

The food went down fast and people kept eating. Across the two weeks that added up to more than 5,000 extra calories.

The firm menu (they ate less)

Chewing took longer, and daily intake dropped by 369 calories. Body fat fell by about a pound across the two weeks, and nobody reported feeling any hungrier.

Both menus were ultra-processed, and both were rated equally tasty. The only difference was how much chewing they took.

In other words, the same people, eating the same category of food, ate hundreds of calories less a day because the food took longer to chew. Their appetite did not change. The food did.

Willpower had nothing to do with it. Not theirs, and not yours either.

So why would chewing matter that much?

Fullness runs on a delay. The signals from your stomach and your gut take around twenty minutes to reach the part of your brain that ends a meal, and that clock starts when you start eating, not when the plate is empty. Soft food beats the clock. It has already been broken down for you at the factory, so it asks almost nothing of your teeth, and a whole plate of it can be gone before the first signal arrives. Chewy food loses that race, which is the point. More chewing means smaller bites, longer time in your mouth, and more of the meal still left when the fullness finally lands.

Nobody stood a chance against that. Not you, not me, and not the most disciplined woman you know.

That’s the part no one says out loud. You were never fighting your appetite… you were fighting food that was built to be gone before your body could answer.

Try this today

At your next meal, pick the firmer version of whatever you were already going to eat. Carrot sticks instead of the smoothie. A whole apple instead of applesauce. Toast instead of soft white bread. Cabbage or iceberg instead of the soft lettuce. Chunky soup instead of blended. Then start the meal with the chewiest thing on the plate and give it two full minutes before you touch anything else. You are not eating less on purpose. All you are doing is giving that twenty minute clock a head start.

Same lunch. More chewing. Your body finally gets a vote.

Promise me you’ll try it today? Saying it out loud is half of what makes it stick.

I’m in. I’ll try it today →

None of this is magic, and chewy food is not medicine. It buys you a few minutes, and those minutes are what was taken from you in the first place.

I got there late myself. It took me years to stop squinting at ingredient lists and start noticing how fast the food went down, and in those years I told a lot of women to hunt for emulsifiers when half of what was working against them was sitting in their hand, soft and easy to swallow.

There’s still time for you. Tomorrow’s lunch will do.

So the next time you’re back in the kitchen an hour after you ate, and the question starts up again…

It was never your fault.

P.S. How many minutes does your lunch usually take, start to finish? Just the number, and hit reply. I’ll tell you tomorrow how you compare.
