Many people envy those super models we see on our television sets or just in magazines. How buff they are, how tall they are, how good looking they are and most of all how they still manage to have a flat stomach in a world where flat stomachs are becoming extinct. Let’s face it, most of us have insecurities when it comes to our tummies. You will find most people wearing big t-shirts or pants that cover their tummies. It has gotten to a point where even more go to swim with tank tops on. Well, not to worry. In this read, we shall highlight the 30-day flat stomach diet that has proven effective in dealing with large tummies. We will also include a workout plan that will also help with your belly. Think of it like attacking the enemy from both sides.


Why You Need To Get Rid Of Your Stomach Overhang

Apart from big bellies, making people have confidence issues and making people look bad, big tummies are just bad for your health. A big stomach is linked to various health conditions like heart attack, type 2 diabetes, hypertension and even some types of cancer. This reveals just how serious of a problem big tummies are and why everyone with a big stomach should be working to get rid of it either in the gym or by checking out what they eat.

Big bellies are bad for your health because they are made of visceral fat. Visceral fat is fat that surrounds the major organs in your body and this reduces your overall quality of life (3). And that is not all, visceral fat is known to increase with age which means the older you get the more it becomes. This is one of the reasons older people have an increased risk of various health conditions like heart attacks, strokes and so on.

Studies show that when men are between their thirties to seventies, their visceral fat can increase by up to 200% (3). It is even worse for women who are between the same age gap as their visceral fat can increase by up to 400% (3). This is yet another reason you need to follow a flat stomach diet that helps you deal with this problem for the long run. This then means that the diet has to be sustainable and effective. When we say the diet has to be sustainable we mean that the diet should not be so restrictive that you cannot follow it for a long period of time. When we say the food plan needs to be effective we mean that it needs to give you the results that you anticipate.

Foods That Will Help You Trim Your Belly

Although one cannot target weight loss, there are foods that have anti-inflammatory properties that will help you get rid of your belly. Here is a list of these foods and how they will help with trimming your stomach. 

Nuts And Seeds

Nuts and seeds have properties that will help you trim your belly and also help reduce the risks that are associated with having big stomachs. Most nuts and seeds contain monounsaturated fats (3). Monounsaturated fats are the good fats that are responsible for reducing the levels of bad cholesterol and increasing the levels of good cholesterol in your body. This property helps reduce the risk associated with various cardiovascular conditions like heart attacks, stroke and more. That is not all, nuts and seeds contain antioxidants that help you repair cell damage in your body and this may help prevent diabetes (3). Nuts and seeds also contain anti-inflammatory properties that will help reduce the size of your tummy.

Red Fruits

Red fruits are yet something else that you need to add to your diet. The deeper the colour, the better they are for your stomach trimming journey (2). Red fruits help turn off the obesity genes and this helps reduce the rate of your stomach growing bigger.


This is one of those foods that has mixed reactions according to different people. There are people who love it and they are people who can’t stand it.  Oatmeal contains fiber that helps you feel full faster and for longer. This prevents you from eating too much, hence reducing your weight and tummy while at it. Fiber is also known to work with the bacteria in your gut to help turn off genes that are responsible for diabetes (2). Oatmeal is just a representative of most of the foods that contain fiber and you should work to add all of them to your diet, like wholewheat pasta, whole grain bread, barley and so on.

Leafy green vegetables will also help with your tummy by reducing the swelling and turning off the fat storage genes in your body (2).

Those are some of the foods that you should consider adding to your diet to help you achieve your goal of having a flat stomach.

30-Day Flat Stomach Diet

We believe individualized diets work better, as people are different and what works for you might not work for the other person. That is why we shall not create a 30-day food plan but we shall give you guidelines on how to create a 30-day diet for a flat stomach as well as a sample diet that you can use as a reference.

Different studies show that low-carb diets are more effective when it comes to reducing the size of your stomach compared to other diets (2). This means for you to have a small stomach, you need to reduce the intake of carbohydrates in your meal plan and increase the intake of proteins. In terms of fats, you need to reduce your intake of saturated fats as they help increase the levels of bad cholesterol in your blood and this leads to an increased risk for various health conditions. Your diet also needs to have foods with a lot of fiber. Fiber is good for your stomach and helps reduce inflammation.
