Your lunch box is the portion control

Your lunch box does the measuring for you—the size of the box sets the portion, so you just have to fill it smart.

The trick isn’t weighing food. It’s picking a box that’s the right size and committing to one box per meal. If you use a giant container, you’ll fill the whole thing and eat it. Get a box that holds about three fistfuls of food, or smaller if you’re not very active. That’s your plate.

Fill it with a simple ratio: half vegetables, a quarter protein, a quarter carbs. You don’t need scales. A palm-sized portion of chicken, a fist-sized portion of rice or potatoes, and the rest of the box stacked with greens or roasted veggies. That’s it.

One more thing: don’t go back for seconds. Fill the box once, eat it, and you’re done. If you’re still hungry after ten minutes, drink water and wait. Usually that’s enough. The whole point is you stop thinking about portions because the box already did the thinking.

You’re not dieting. You’re just packing lunch.
