Amonia smell in my nose after I exercise

According to the Livestrong site, this means you are consuming more protein than your kidneys can handle, and you should eat more carbs, and less protein.

I guess it is the same, but like the OP said the amonia smell is actually in my nose - like someone is sticking a smelling salt up there - I don't smell it in my sweat, but maybe I just think I don't...

I agree that this was a great question. I have had it happen in the past and never knew why. Now if only I knew why my thighs do that snappy thing after I get home from a good walk LOL.

Ironically, I just read this today:

Post Workout Nutrition

In general, you'll maximize your fat loss if you wait about an hour after your workouts before eating. The exception, in my view, is when you smell ammonia. Ammonia is essentially nitrogen, and that sensation after a workout is a signal that you've raised your cortisol levels enough to trigger the breakdown of amino acids by the liver (gluconeogenesis). When the body needs energy, it metabolizes glycogen, then fat, then protein. If one isn't fast enough, it goes down the list. But if it's going to feed on protein, you want it to go after something other than muscle tissue. So if you smell ammonia, you should have a protein and carbohydrate containing supplement immediately after your workout, preferably along with a protein stimulating supplement such as L-Leucine (whey protein is about 20-25% Leucine).

Even if you wait to eat a regular meal, there's increasing evidence that availability of the "branched-chain" amino acid Leucine, even just a gram, closely following a workout, can kick-start new muscle synthesis.

A few additional reasons to avoid spiking insulin except after a weight-training workout. About one in four people are insulin resistant, meaning that the pancreas has to pump out a lot more of the stuff in order to be effective. That excessive insulin reduces the ability of the body to burn fat as energy even after the glucose is cleared. Insulin resistance also typically leads to an increase in "visceral fat" around the organs, particularly in the abdomen, and increases the risk of coronary disease. By keeping your carbohydrates low-glycemic and your portion sizes in control, you reduce the need for this excessive output of insulin, and you keep your fat-burning in high gear.

Insulin resistance is more common if you have diabetes in your family, or if your diet has been high in sugar, high glycemic carbs, and saturated fats. My vote for worst food in the world: funnel cake (called "elephant ears" in the Midwest ): white flour dough, deep fried in lard, covered with powdered sugar. If you ever find yourself standing in line for this stuff, just skip on over and stand in the line to get your head examined.

Fortunately, one excellent fact is that exercise itself improves insulin sensitivity. Also, you'll significantly improve your fat loss if you concentrate on eating low glycemic carbs in your portions. A few supplements are known to improve insulin sensitivity: alpha lipoic acid ( ALA ), green tea extract, and chromium picolinate. All are available at any GNC. Normal dosages (read the label on whatever brand you pick) are sufficient. Since they change the responsiveness to insulin, diabetics who are insulin-dependent should use these only under a doctor's supervision.
