When John Goodman talked about how he lost his first 100 pounds, he didn't credit a diet plan or a specific food he cut out. He credited portion control. That's it. No tracking app, no eliminated food group, just eating less of what he was already eating.
That's the part most people skip past because it sounds too simple to actually work. Here's how it actually works, and how to do it without turning every meal into a math problem.

What Portion Control Actually Means
Portion control isn't about restriction or cutting out foods you like. It's about matching how much you eat to what your body actually needs, instead of defaulting to however much fits on the plate, the bowl, or the bag in front of you.
Most people eat more than they realize not because they're making a conscious choice, but because portion sizes at restaurants, in packaged food, and even in home cooking have grown steadily larger over the years. Portion control is about noticing that gap and closing it, not about eating tiny amounts of food.
The Plate Method
The simplest way to practice portion control without counting or measuring anything is the plate method. Split your plate into sections:
- Half the plate: vegetables, the kind you'd find in Mediterranean style meals like grilled zucchini, salad, or roasted vegetables
- A quarter of the plate: lean protein, like fish, chicken, or beans
- A quarter of the plate: whole grains or starchy vegetables, like rice, quinoa, or sweet potato
This works because it shifts the default without requiring you to track anything. You're not counting calories, you're just filling the plate in a different order.
Using Your Hand as a Guide
If you don't want to think about a divided plate every time, a simpler version uses your own hand as a rough guide:
- A palm-sized portion of protein
- A fist-sized portion of vegetables
- A cupped-hand portion of grains or starches
- A thumb-sized portion of added fats like oil or dressing
This isn't a precise measurement, and it doesn't need to be. It's a habit you can use anywhere, including at a restaurant, without pulling out a scale or an app.
Slow Down Before You Decide You're Still Hungry
One of the most common reasons people eat past the point of being full is speed, not hunger. It takes time for your body to register that you've eaten enough. Eating slowly, putting your fork down between bites, or just pausing partway through a meal before deciding whether you want more, gives that signal time to catch up.
This is closer to what Goodman described about his own approach. He didn't talk about restriction, he talked about recognizing when he didn't need more, and stopping there.
Smaller Plates, Same Meal
If you're used to filling whatever plate is in front of you, switching to a smaller plate is one of the easiest changes to make. The same portion looks and feels more complete on a smaller plate, which makes it easier to stop without feeling like you're eating less.
You Don't Have to Do This at Every Meal
Portion control works as a general default, not a rule you have to follow perfectly. Some meals, like a holiday dinner or a night out, aren't the ones to practice this on. The goal is for it to be your default most of the time, the same way it was for Goodman over the course of his weight loss, not something you're rigidly enforcing at every single meal for the rest of your life.
Pairing Portion Control With What You Eat
Portion control works best alongside the kind of food you're portioning. A plate that's half vegetables and a quarter lean protein is naturally easier to stay satisfied on than a plate that's mostly refined carbs or fried food, even at the same portion size.
