4 Signs of a Potassium Deficiency - How to Avoid Potassium Deficiency Both cramps and fatigue can be clear indicators of a potassium deficiency. Add foods that contain this mineral to your diet to avoid major health problems. Potassium deficiency can affect your nerves and their interaction with your muscle cells in your digestive tract, the heart, and other bodily systems. Most of the potassium in your body is found in your cells. When you have a balanced daily diet you keep your potassium levels stable with ease. If your diet is very poor, on the other hand, choosing unhealthy products or missing some key sources, youll have a deficiency in potassium. But how do you know if you have a potassium deficiency? In todays article well explain the signs. Pay attention to see if you have any of them. 1. You feel potassium deficiency: youre tired and weak The first symptoms of a potassium deficiency are usually muscle aches, cramps, and abnormal weakness. This weakness will not just affect your arms and legs, but also your respiratory and gastrointestinal muscles. Low potassium levels prevent your muscle cells from rapidly recharging their energy stores. This causes them to have difficult

Overview Of Disorders Of Potassium Concentration

(Video) Overview of the Role of the Kidneys in Acid-Base Balance Overview of Disorders of Potassium Concentration By James L. Lewis, III, MD, Attending Physician, Brookwood Baptist Health and Saint Vincents Ascension Health, Birmingham Potassium is the most abundant intracellular cation, but only about 2% of total body potassium is extracellular. Because most intracellular potassium is contained within muscle cells, total body potassium is roughly proportional to lean body mass. An average 70-kg adult has about 3500 mEq of potassium. Potassium is a major determinant of intracellular osmolality. The ratio between potassium concentration in the ICF and concentration in the ECF strongly influences cell membrane polarization, which in turn influences important cell processes, such as the conduction of nerve impulses and muscle (including myocardial) cell contraction. Thus, relatively small alterations in serum potassium concentration can have significant clinical manifestations. Total serum potassium concentration may be Clinical manifestations of disorders of potassium concentration can involve muscle weakness and cardiac arrhythmias. In the absence of factors that shift potassium in Continue reading >>

    Unfortunately, biochemistry is not the kind of topic that can be easily researched online without formal training. There are a number of points you make that are incorrect. I keto myself, so don't think I am trying to attack your general position here.
    Starvation and the keto diet are actually nearly identical from a biochemical perspective. The key pathway is fat mobilization, where fatty acid chains are broken down two carbons at a time to produce energy. When this process starts to happen faster than your body can manage it, some of the chemical constituents of the process actually break down to become the ketones that can be detected in the urine and breath. In other words, ketones are a side effect, rather than a major player.
    The idea that a calorie deficit, ie starvation, is somehow bad, is incorrect. Anybody who is using diet and exercise to become more lean is doing the same thing. There is no magic method to lose weight without some form of starvation. The reason why the keto diet does not cause significant lean tissue loss is that the starvation involved is not sufficiently severe.
    An important point that you bring up is the idea that the keto diet stabilizes insulin levels. This is basically correct. Insulin signals cells to take up glucose from the blood, and also tells the liver to begin glycogenesis - the process of packing glucose into glycogen. High blood sugar triggers this. These effects are basically reversed by adrenaline, which tells the liver to start breaking glycogen down to make glucose.
    Part of the difficulty with this is that with a normal diet, blood sugar spikes after meals. This leads to cyclic variance in levels of glucose, insulin and adrenaline. As the cycle progresses toward the adrenaline end, you start to get cravings for foods that will once again spike your blood glucose.
    However, when you are relying on fat mobilization to make glucose, these spikes are greatly reduced. Fat mobilization is not efficient, and is not able to provide sudden bursts of glucose. It is more constant. This makes athletic activity much more difficult aswell.
    But this is the real reason why the keto diet works - it mitigates the cycle of spiking and lowering blood sugar, providing a more level and constant supply. This reduces the propensity for craving food.
    In essence, the keto diet is not unique in terms of the basic biochemistry of metabolism. It simply makes 'starvation' more tolerable, and easier to manage. For many of us, that is exactly what we need.
    Edit - swapped 'gluconeogenesis' with 'glycogenesis'.

    Insulin signals cells to take up glucose from the blood, and also tells the liver to begin gluconeogenesis - the process of packing glucose into glycogen. High blood sugar triggers this. These effects are basically reversed by adrenaline, which tells the liver to start breaking glycogen down to make glucose.
    Insulin inhibits gluconeogenesis (creation of new glucose), you probably meant glycogenesis (conversion of glucose to glycogen)?

  3. datums

    You are right on that one. The word I was looking for was glycogenesis. It can be a little tricky to remember that between glycolysis, glucogenesis, and gluconeogenesis, one means glycogen synthesis, and the other two mean glycogen breakdown.

High potassium level can cause symptom such as: Weakness, Depression, Dehydration, Heart problems, Paralysis, Kidney failure, Renal necrosis and many others. Most dietician recommend an intake of 2 to 5grams of potassium a day for healthy people. Kidney patient would need less than this. The right daily potassium intake for a stage 4 patient would be no more than 2,5grams. However, potassium intak

Potassium - An Overview | Sciencedirect Topics

Potassium is the most abundant cation in living cells and plays a major role in maintaining an electrical potential between the inside and outside of cells, and as such, is critical to cellular excitability of muscle cells and neurons with particular relevance to motor, cardiovascular, and nervous systems function. In Clinical Veterinary Advisor: The Horse , 2012 Potassium is critical for many biochemical cellular reactions. It is ingested daily and renal excretion is regulated by aldosterone. Potassium is also lost in feces and sweat. Most of the body's potassium is found intracellularly. Serum (extracellular) potassium is less than 2% of the whole body potassium.

    hey need help still :/
    does someone take metformin on keto?
    is this safe or does the blood sugar drop to low? or does acidosis occur?
    I just dont know why I dont lose weight anymore.
    Started workout 2x a week and 1x yoga for flexibility.
    changed macros (high fat high prot, high fat+mod protein, etc), kcal (2500, 2200, 2000, 1700, 3000, 2500,etc) and cut nuts, cheese (lactose intolerant) and sweeteners. still nothing.
    also did 3 refeeds on FR evening and 1 cheat weekend for more glucagon and leptin and have more hunger now :/ great^^
    but weight is unaffected... also have now quite the carb creeps on the weekend.. damm..
    does keto reverse insulin resistance or just dampen it because there are no carbs and this could be a reason why there is no loss anymore?
    blood profile is perfect....thyroid a bit low but was before already.. maybe add iodine? only use sea salt right now..
    should I try to reverse diet and add carbs for insulin sensitivity?
    is this usefull or will it reawaken my insulin resistance??

The Plasma Potassium Concentration In Metabolic Acidosis: A Re-evaluation.

1. Am J Kidney Dis. 1988 Mar;11(3):220-4. The plasma potassium concentration in metabolic acidosis: a re-evaluation. Magner PO(1), Robinson L, Halperin RM, Zettle R, Halperin ML. (1)Renal Division, St. Michael's Hospital, Toronto, Ontario, Canada. The purpose of these investigations was to describe the mechanisms responsiblefor the change in the plasma [K] during the development and maintenance ofhyperchloremic metabolic acidosis. Acute metabolic acidosis produced by HCIinfusion resulted in a prompt rise in the plasma [K], whereas no change wasobserved during acute respiratory acidosis in the dog. After 3 to 5 days ofacidosis due to NH4Cl feeding, dogs became hypokalemic; this fall in the plasma[K] was due largely to increased urine K excretion. Despite hypokalemia,aldosterone levels were not low, and the calculated transtubular [K] gradient wasrelatively high, suggesting renal aldosterone action. Thus, rather thananticipating hyperkalemia in patients with chronic metabolic acidosis due to aHCl load, the finding of hyperkalemia should suggest that the rate of urinary Kexcretion is lower than expected (ie, there are low aldosterone levels or failureof the kidney to respond to this Continue reading >>

    Heard quit a few people have given up Caffeine while on Keto due to the boosts in energy.
    I'm at the point right now where I'm addicted to Caffeine. 2-3 pots of coffee a day (pretty much all day and I'll taper off in the evening) and about 200mg in the form of a Pre-workout before exercising in the morning.
    Unfortunately, I work Full-Time and can't just quit 'Cold Turkey' and detox for a few days.
    I've been in Ketosis for about 1-2 days now, started Keto last Friday. Any tips on how to kick the caffeine habit while on Keto?
    Should I gradually reduce my intake? Should I wait till I'm Keto-adapted?
    For those who've given up caffeine while on Keto, how did you do it?

  2. anbeav

    I'd let your body get adjusted and keto-adapted first before you try to kick caffeine to the curb.
    I quit coffee several years ago because I couldn't sleep at night. I sort of just quit but I wasn't drinking near as much as you. When you do quit I would do it slowly and would start on a weekend.

  3. MikeDuck1

    Thanks, I'm hoping once I get keto-adapted I'll just have a ton of energy first thing in the morning and just kind of 'forget' to drink coffee.
