"You live as long as your waist is small."

Optimal Body Composition Strand
The HOPE Protocol

1 THING TO KNOW

Stop eating earlier tonight.

Not less.

Not perfectly.

Just earlier.

One of the simplest experiments you can run for your weight is to create a longer stretch between your last bite tonight and your first bite tomorrow.

1 THING TO DO

For the next seven days, try this:

Finish dinner before 7 PM.

Then close the kitchen.

No evening grazing.

No handful of nuts while watching television.

No “healthy” little snack before bed.

Water or a non-caloric beverage? Fine.

Food? Tomorrow.

WHY I WANT YOU DOING IT

Your body doesn't just respond to what you eat.

It also responds to when you eat.

Eating late—especially when it extends your daily eating window—can work against glucose regulation, appetite control, sleep, and body-composition goals.

And here's something I learned during 46 years of helping more than 10,000 women and men:

The little bites count.

People would tell me they stopped eating after dinner.

Then I'd ask a few more questions.

A few almonds.

A bite of cheese.

Half of something left on the counter.

Suddenly, “I don't eat after dinner” had become a three-hour eating event.

Your metabolism doesn't know it was “just a bite.”

YOUR 7-DAY CHALLENGE

For seven nights:

Dinner finished by 7 PM. Kitchen closed afterward.

Then pay attention to:

Your morning hunger.

Your sleep.

Your morning weight.

And especially how you feel when you wake up.

Don't try to change ten things.

Change one thing and observe what happens.

That's how Vicky and I approach our health in our 60s and 70s.

ONE QUESTION

What's the hardest time of day for you to control your eating?

Morning?

Afternoon?

Or after dinner?

Hit reply and tell me.
