Answer 1

I think you can use

'If you eat 5 cookies you\'ll consume 200 calories'.match(/\d+(\.\d+)?\s\w+/g)

• \\d+ - digits
• \\s - a space after the digits
• \\w+ - some set of characters after the digits

Demo: RegEx

Answer 2

If your text will always have the form If you eat <count_of> <something> you'll consume <some> calories , the you can use the regex below

var regex = /^If you eat (\d+) (\w+) you'll consume (\d+) calories$/;

The second, third, and third matches will be the one that will interest you (the first match is the actual string).

If you want to capture the ( ) together instead of capturing into two separate matches, you can replace (\\d+) (\\w+) by (\\d+ \\w+) .
