Posting on her website, Allen says: "As a busy mum of two, I know how easy it can be to go overboard with your daily calorie requirements! You think you're being healthy and making great meals but the weight isn't shifting."
She continues: "When it comes to making meals and you're trying your best to make everyone in the family happy, sometimes you may not realise the portions are too large or you use ingredients that could be swapped with healthier options."
The Healthy Mummy blogger has published seven meals she has made minor tweaks to - dinners the whole family can enjoy.
Limiting cheese and reducing the amount of butter gets the meal from 690 calories down to 387 calories.

MEXICAN LASAGNE
To cut this bad boy from 932 calories to just 505, Allen suggests cutting 800g of mince down to 400g and switched kidney beans for a can of salt-reduced kidney beans.
She used light sour cream and reduced full fat cheese from 150g to 130g reduced-fat cheese.
Removing 250g of white sauce from the lasagne was also a big helper in reducing calories.
