They can disappear and appear without you even knowing. On a more serious note, this has to do with the amount of water your body retains. So the next question is, why does my body retain more water some days than others? Well, that’s a great question!
This must do with 100% with what you ate and the amount of water you had the day before or sometimes even the day off. First you need to understand that salt and sugar can make your body retain more water. “Table salt is the most common cause of water retention. Excess sodium makes the body hold extra fluids in the cells.”
Sugars also known as carbohydrates is the second most common cause of retaining water. If you consume more carbs than what your body uses as energy your body will store it as glycogen. Glycogen contains water and the more glycogen your body stores, the more water it retains.
Also, this might sound counter intuitive, but a well hydrated body is less likely to retain water.
So, if you lower your salt intake and don’t overindulge on carbohydrates, you will be able to see those abs.
Strong abs aren’t the most important component of a visible six-pack; low body fat is. If you have too much subcutaneous body fat covering your abdominal area, then no matter how many hours of crunches or leg raises you do, you won’t be able to see your six-pack.
The most effective action toward achieving those ripped abs is to clean up your diet. When it comes to your abs, training can only get you so far. You need a smart meal plan to lower your body fat percentage and uncover your abs; otherwise, all your hard work in the gym will count for naught.
You cannot lose body fat in specific areas of your body by training that body part more often. If someone ever tells you that you’ll lose your gut by performing abdominal exercises, slap that person in the face and then explain to him or her that it’s impossible to control where body fat comes off your body. The only way to strip the fat from your abs is by slowly and gradually burning it off from your entire body through cardio, nutrition, and resistance training.
Unfortunately, abdominal fat is usually the last bit to come off and the first to come back. The tenacity with which abdominal fat wants to cling to your belly can make dieting and exercise discouraging. The key is consistency. It may take months or even years to uncover your abs, but if you stick to being smart in the kitchen, you’ll eventually see results.
