    Hey guys, quick question.

    Since I started working out with weights three weeks ago, I've been eating tons and tons of food. More than I ever would've before, and I could already eat a fair bit before that icon_smile.gif.

    Today I did a heavy workout in the early afternoon, and then this evening I was at home and I started feeling a little shaky and sick. Not hungry, but more like I was coming down with something. I ate some dinner, and pretty quickly I felt better... so I ate a bunch more (fried up some potatoes/meat/etc.) and all of the 'sick' feeling went away, and now I just feel exhausted.

    Is that a sign that I'm not eating enough comparative to the amount I'm working out, or does it mean that I'm exercising too much? Or something else totally unrelated?

    I'm trying to figure out if I just need to be shoveling in more food or if I need to cut back a little on the workouts.

    sounds like low blood sugar because you didnt eat and your energy levels were low. Did you eat after the workout at all. If you expended that much energy in the early afternoon and still had not eaten several hours later it had to be low sugar

    You did not describe what you meant by a sick feeling, so I assume you mean nausea.

    There are several common causes. The first as mentioned by Rujock is hypoglycemia. This occurs because the muscles have consumed much of the available glucose. Since the brain now has an insufficient energy supply, it begins to malfunction. Symptoms like dizziness, nausea, mental confusion, shakiness, and weakness can occur. Hypoglycemia is one of the causes of the "bonk" or "hitting the wall" described by endurance runners and bicyclists. To help prevent this problem, consume an adequate amount of carbs with exercise. Don't go into exercise in a fasted state. If you are into muscle building, this is a good time also to take protein since it is avidly taken up by the exercised muscle.

    Another cause of a sick feeling is mild dehydration. Make sure you are hydrated when exercising.

    Dizziness can occur if you stop cardio suddenly without a cool down period. The sudden stop causes a precipitous drop in blood pressure which results in inadequate amount of blood reaching the brain. The hypotensive response can be a significant problem in older individuals and individuals prescribed blood pressure medications. I had to come to aid of an older man that passed out after suddenly stopping the treadmill.

    The final problem I'm aware of is "exercised induced nausea''. This problem occurs in some people, but not all, after intense exercise. You may see this problem after a HIIT session. Some researchers believe it is do to endorphins released during exercise.

    The following information about exercise induced naseua was from the following article
    http://www.hiitsource.com/exercise-induced-nausea/

    Nagoya University in Japan did a study and found the following
    Exercise intensity DOES impact on severity of exercise induced nausea
    Food intake DOES impact on severity of exercise induced nausea
    Gender DOES NOT impact on severity of exercise induced nausea
    Level of fitness DOES NOT impact on severity of exercise induced nauseaicon_eek.gif

    Although you may feel like it, vomiting after HIIT will not kill you and it will be over usually quite quickly after vomiting and
    some resticon_smile.gif

    Recommendations were to stay away from large meals prior to exercise. Restricting fluid only worsened the symptoms.
    For the individuals unable to tolerate HIIT, it was recommended to go back to the boring 60 minute cardioicon_cry.gif

    These are fantastic tips, thanks! I am every now and then experiencing similar symptoms even though I eat well and regularly with an eye on the quality of the food as well. I believe, judging by the above, my problem is the intake around my gym routines (lunch hour) and in particular exactly then having to be extra careful about the timing as well as carb/prot mix. I oftnr take a carboprot shake after workout but probably should consider taking it rather before. With a relatively high metabolism (and difficulties to 'bulk up') I hit the HIIT quite easily if I am not careful.

    Thank you so much for the information. I've done some experimenting and I think I was eating too little, and what I was eating was too much salad/fruit... not enough protein/carbs in my diet to support the amount of exercise I was doing.

    If you were shakey and feeling like crap, chances are VERY GOOD that you had low blood sugar. That's ONE of the way it manifests itself.

    You can get a glucose meter at Walmart. Next time you feel like that, test your blood sugar. If it's below 80, you need to eat something. Or, next time you feel like that, it two pieces of candy. If you feel better in about ten minutes, you've found the problem: you need more CARBS.

    Lots of office workers suffer the mid afternoon headache. It's not really a headache, but, rather, just low blood sugar.

    Carbs are ESSENTIAL in any good diet. You need them to perform work; especially leg work.
