Reddit reviews MECO Spaghetti Pasta Limiter Noodle Measurer Portions Controller Tool Adjustable

I think OP is referring to a tool like this or this.

How much pasta you eat in one sitting has to do with your height and weight, yes. It also depends on what kind of pasta you're talking about. You can likely find approximate measurements for your size somewhere on the internet, then measure out the dry pasta in those amounts.

If you want to make it extremely easy, go with a long-noodle pasta like spaghetti or something similar and use a serving measurement tool to make sure that you're getting the same amount each time. Here's an example of one; here is a different one.

You can also look at the nutrition facts and use measuring cups to measure out serving sizes as labeled on the packaging. The measurements for servings in the nutrition facts are using the dry pasta (before being cooked), so you don't even have to worry about figuring anything out.

If you wind up cooking more pasta than you could or should eat in one sitting before a match or training session, you do not have to throw the excess away. Get out a ziplock bag, put a small amount of olive oil in the bag (start with about a half tablespoon) and then put the leftover cooked pasta in the bag. Shake it up and make sure it's all lightly coated in olive oil - add small amounts of oil if necessary. Put the pasta in the fridge and you can have it the next time you want pasta. To reheat the pasta you can either try your microwave (though I'd only recommend this if your microwave has a Reheat setting option - it effectively uses half-power to heat the food, so that you don't wind up with that dried-out nasty mess you usually wind up with when microwaving leftovers) OR you can boil a new pot of water, drop the noodles in and stir around for about a minute or so, just enough to get them hot again. Then serve as usual.
