I have and enjoyed doing it. The only issue I have really had was keeping up with it. I follow a low carb/keto whole food plan now so I'm less concerned about it now. This morning I had steak and eggs, nothing added so no big thing. I think that MFP is important for people that follow a less rigid plan. I rally saw how much carbs and sodium I was taking in. The sodium scared me.
The Ketogenic Diet
Your fear of sodium, especially on the Ketogenic Diet, is unfounded.
More sodium is required on the Ketogenic Diet, as well as other minerals.
If you are on the Ketogenic Diet (many believe they are but aren't) increasing sodium intake is vital.
Keto Flu
Those beginning a Ketogenic Diet often have flu like symptoms that are caused by a decrease in sodium levels.
Thus, individual who begin a Ketogenic Diet are advice to increase sodium intake. One method recommended is to consuming a Bullion drink that contains between 800 to 1,000 mg of sodium.
Some Bullion also contain another mineral that works with sodium, potassium.
Sodium is also a vital mineral for individual on other types of diets...
Sodium, Your Secret Weapon | T Nation
Studies in Canada at McGill and McMaster Universities have concluded that unless one has a specific and serious condition that would preclude him from taking in salt, then salt intake will produce no negative health problems, and could actually be health promoting. As a matter of fact, only 10% of hypertension cases have a known cause, and in almost all of these cases, the cause was either genetic or stress related.
...High-performance athletes should
not avoid sodium. They should, in fact, ensure that they get adequate amounts of sodium every day to prevent negative metabolic consequences, and to promote maximum performance.
The article above go into greater depth in explaining the importance of sodium for athletes.
My Ketogenic Diet
As I have noted on this site, I've been on the Ketogenic Diet for almost 2.5 years.
I maintain a high sodium intake, generously salting my food and consuming a Knorr (brand name) Chicken Bullion beverage prior to training; 820 mg Sodium and 210 mg Potassium.
Summary
The dogma in the vilification sodium is unwarranted for healthy individual.
