This one simple tool can make the difference between building lean muscle, burning bodyfat, and achieving your bodybuilding and fitness goals and making hardly any progress at all.What I’m about to talk about is very simple, and I know you’ve heard of it before, but chances are you’re not applying it as part of your routine.It is keeping a journal…Keeping a journal is not some cheesy little thing that teenage girls like to do in their spare time. But it is one of the best tools you have available for tracking your nutrition and finding out where you can make improvements to move yourself closer towards your fitness goals.Your nutrition journal doesn’t have to be anything fancy or complicated, just a simple notebook will do. All you need to do is each day write down what you eat and when you eat it. You can also keep track of other things like your bodyweight, bodyfat percentage, etc.Having a diet log book provides you with the information you need to constantly improve your eating habits and lifestyle. You’ll have everything written down on paper so you’ll instantly know if you’re eating properly or not. You’ll notice eating habits and cycles that you may have not been aware of before.I recently read a study that showed on average, overweight people forgot approx. half of the foods they ate over the course of the day. They either forgot it entirely or they underestimated how much food they ate.And I’ve also seen the opposite happen with underweight people who are struggling to gain muscular bodyweight, they often ‘underestimate’ how much they are eating and then wonder why they can’t gain weight.By simply monitoring your food intake with a nutrition journal you’ll have more control over your results then people who try to “wing it” with their eating.For the first week of keeping a nutrition journal I don’t want you to change a thing with your eating routine, just write down what you eat and when you eat it. But try to be as specific as possible…For example, don’t just write down for breakfast at 7:00 am I ate “cereal and toast”. Write down what kind of cereal, how much, how many slices of toast, what you had on it, etc. and simply do this for each of your meals.Keeping a food journal is going to take some time and effort. But the rewards of a lean toned body is well worth the effort of writing down your food intake. Guessing is not good enough.After doing this for a full week, simply review your nutrition journal and ask yourself:”Where Can I Improve My Eating To Move Closer Towards My Fitness Goals?”It could be something as obvious as:”I shouldn’t have eaten that double cheese burger, with large fries, and a DQ Blizzard for lunch yesterday.”Or it could be something less obvious like:”I need to eat more quality protein with my breakfast.”When you keep an accurate journal of your eating like this it becomes a lot easier to pin point places where you are making mistakes and where you can improve. Just being conscious of what you are eating will automatically cause you to make better food choices.When starting any new eating plan, just move yourself in the right direction and focus on improving. Don’t try to be perfect. But do get in the habit of recording your food intake, and then each week review your journal and pick 1 or 2 areas that you are going to focus on over the next week.If you keep track of everything you put in your mouth for the next several weeks, you’ll find that you’ll automatically make better food choices as part of your regular eating routine. This will make it a lot easier to get muscle building and fat loss results that you are looking for.A great recourse that you should get to help you with calculating out nutritional information is a calorie and nutritional information book. You can also do a search online as there are several websites now that allow you to search for virtually any food and instantly get the calories, protein, carbohydrates, fat, etc. This will make keeping your nutrition journal a lot easier.
