How to make dinner filling while eating fewer calories

You make a smaller bowl of pasta because you're trying to lose weight. Dinner takes six minutes to eat, and by nine you're back in the kitchen wondering what else is around.

Try making the same dinner take up more room on the plate. Use a little less of the most calorie-dense part and add vegetables you actually like in its place. Keep the sauce and the rest of the meal. This is a way to lower the calories without turning dinner into a tiny, joyless version of itself.

How can a bigger dinner have fewer calories?

A gram of dry pasta carries more energy than a gram of green beans. Vegetables bring more water and bulk. For the calories to come down, the vegetables need to take the place of some pasta. Adding them to your unchanged portion makes dinner larger and adds calories.

Here's an example using round numbers from imaginary food labels. Say your pasta has 350 kcal per 100 g dry, and your frozen green beans have 30 kcal per 100 g:

• Your usual 100 g of dry pasta: 350 kcal.
• 60 g of dry pasta plus 200 g of green beans: 210 + 60 = 270 kcal.

That's 80 kcal less for those ingredients, and the finished plate is likely to be larger. This example only counts the pasta and beans; sauce, cheese, oil and anything else still count in both versions. Real packs vary, so check yours if you want the actual number.

Weigh the pasta dry in both versions. Cooked pasta gets heavier because it absorbs water, not because it gains calories. If you cook a batch and divide it later, the raw-to-cooked calculator can work out a cooked portion from the dry batch.

Will it actually keep me full?

It might. The NHS suggests filling about half your plate with vegetables when you're trying to lose weight, partly because they add volume for relatively few calories.

In a small feeding study, 41 adults ate meals with different amounts of puréed vegetables mixed in. On the lower-calorie days they ate roughly the same weight of food, consumed less energy, and reported similar hunger and fullness. That's encouraging, but it was three laboratory days. It doesn't promise that green beans will keep you full until bedtime, or prove long-term weight loss.

So treat your own appetite as useful feedback. If you're hungry soon after dinner, a larger heap of vegetables may not be the whole answer. Check whether the meal has something substantial alongside them, such as eggs, fish, tofu, beans or meat. You don't need to win a contest for the smallest pasta portion.

What would this look like on a normal Tuesday?

Stir frozen green beans into a tomato pasta sauce while the pasta cooks. They don't need a separate pan, and frozen ones wait patiently for the next Tuesday. Tinned beans work too; drain them and add them near the end. Mushrooms, courgette or carrots can do the same job if you prefer them. Choose one you would willingly eat; cauliflower rice is a poor bargain if you hate cauliflower.

Watch what goes in the pan with them. A lot of oil or creamy dressing can easily cancel out the energy saved by using less pasta. That doesn't make either ingredient off-limits. It means the whole meal is what counts. The recipe calorie calculator adds up the pasta, vegetables, sauce and oil if you want a number for the pan or per serving.

Is this enough to lose weight?

A single dinner doesn't decide your weight trend. This change helps only if it makes your overall eating pattern lower in energy and still comfortable enough to repeat. If the new meal leaves you hunting for snacks later, change it again instead of trying to tolerate the hunger. If you track calories, the guide to judging your trend over a few weeks is more useful than judging one dinner.

At your next ordinary dinner, start with what you already cook. Make a little less of the pasta or rice, add a vegetable you like, and see how the meal feels. No new diet and no six-box meal-prep project required.
