There are all kinds of trainers, videos and products that say they can get you a flat stomach in no time, but there are no shortcuts to six pack city. It takes a lot of work, discipline and time. As this video from the PictureFit YouTube channel explains, the only guaranteed way to get a flat stomach is through — brace yourself — diet and exercise. To be more precise, you need to use up the fat you have stored around your abs. But because spot reducing is a myth, you'll have to focus on reducing the fat throughout your entire body. To do that, you'll need to burn more kilojoules than you put in every day, but it's more complicated than "eat less, move more". You need to eat fewer carbs while increasing your lean protein intake. Why? Your body will try to burn carbs for energy first, but if you haven't ingested many carb-heavy foods, your body will target fat for energy instead. Plus, protein makes you feel full longer. You also need to incorporate resistance training in your workouts to keep yourself from losing muscle mass in addition to fat (more muscle means burning more kilojoules naturally). Low intensity cardio training can help with burning more kilojoules each day, but it won't help you retain muscle, so make sure it's not the only thing you do.
It could take months before you start to notice a difference, so don't expect the process to be easy. And if you do manage to develop a nice, toned six pack, it probably won't change your life. You don't need a perfectly flat tummy or washboard abs to be healthy and look good. Keep in mind, people can't see your abs under your clothing, it's hard work maintaining them (nonstop dieting), and the low levels of body fat required to have a flat stomach may actually leave you looking less athletic and attractive. So, if you really want a flat stomach, get ready to fight for it. Otherwise, just shoot for being healthy.
