If your jeans are suddenly feeling a tad tight around the middle and you're wondering how to get a slim waist, we’re here to help. Our easy flat tummy diet plan saves calories, boosts your metabolism, and takes advantage of foods scientifically proven to burn belly fat.
What’s more, you can expect to lose up to three pounds a week, depending on your age, how active you are and how much you need to lose.
In addition to following the diet plan outlined below, we also recommend following an exercise schedule that is designed to burn fat (try a HIIT workout) and target the core - see our guides to the best exercises for weight loss and best workouts for abs, or give our 30 day ab challenge a try.
How the flat tummy diet plan works
We’ve kept things really simple. Just choose a breakfast, lunch and dinner from the list below, plus two snacks a day. There are six options for each of the three main meals, so there’s enough variety to keep things exciting and avoid boredom - a diet plan’s worst enemy.
Matcha is also a pivotal part of the diet plan to lose belly fat. Each morning at breakfast, and once as part of your snacks, enjoy a matcha latte. Simply whisk 1⁄2tsp matcha powder into 150ml cold or hot skimmed milk.
Matcha is powdered green tea, which is rich in a substance called epigallocatechin gallate (EGCG). Studies have shown this catechin compound enhances fat loss, particularly around the belly (opens in new tab).

Flat tummy diet plan tips
- Ditch the salt
Too much salt causes water retention that can give you a bloated, puffy look. We get most of our salt from processed foods, so cook from scratch, and shop for the foods with a green traffic light for salt.
- Consider taking a probiotic supplement
Probiotics are beneficial bacteria that help crowd out the harmful gut bacteria which ferment and can contribute to a bloated belly.
Also, look out for foods rich in prebiotics. Onions, garlic and artichokes are naturally rich in them, and you can also buy prebiotic-fortifed foods.
- Think about your posture
Slouching can give you a pot belly, even if you’re the ideal weight. Stand tall and hold in your tummy! Pilates is great for posture, as well as the core muscles around your abdomen that give you that fat look.
