The notion of too much protein on keto is a myth. Many people in the keto group falsely keep their protein intake low to avoid glucose development by a process called gluconeogenesis.
Because of this, beginner keto dieters can never see the long-lasting results they hope for in a low-carb, high-fat lifestyle. The reality is that too much protein on keto is a myth.
If you reach a weight loss plateau, experience a dip in energy, or note hormonal imbalances, increasing your protein intake can help.
Your protein consumption would only be harmful to your keto diet if it raises insulin levels to the point that ketone production is decreased.
That being said. However, there are little known effects of eating “too much protein on keto” because it mainly focuses on limiting carbs intake and upping protein and fats consumption. These include;
1. KETO FLU
One of the major effects of eating too much protein on keto is the keto flu phenomenon. As your body depletes its carb stores and transitions to using ketones and fat for fuel at the beginning of this eating pattern, you may experience flu-like symptoms.
These involve headaches, dizziness, weakness, nausea, and constipation—partly due to dehydration and electrolyte imbalances that arise when the body adjusts to ketosis.
Although most people tend to feel better within a few weeks, it is important to control these symptoms during the diet by staying hydrated, and eating foods rich in sodium, potassium, and other electrolytes.
2. AMMONIA BREATH
The body forms ammonia as it digests and breaks down proteins. When you eat too much protein on keto, the processing of ammonia will make your breath smell. So, if your breath smells like Windex, your protein intake may be high enough to get you out of ketosis.
3. CHANGES IN GUT BACTERIA AND DIGESTIVE ISSUES
Studies in children with epilepsy on ketogenic diets found that 65 per cent reported constipation as a common side effect. Furthermore, fibre feeds the beneficial bacteria in your intestines.
Having a healthy intestine can help boost immunity, improve mental health, and reduce inflammation. Low carbohydrate diets that are deficient in fibre, such as keto, can negatively affect your intestinal bacteria, although current evidence on this subject is mixed.
4. NUTRIENT DEFICIENCIES
As stated before, the keto diet restricts the intake of some food groups with the main one being carbs, nutrient-dense fruits and legumes. In particular, some studies indicate that a keto diet may not have enough calcium, vitamin D, magnesium, and phosphorus.
Over time, eating too much protein on keto and restricting other food groups may result in nutrient deficiencies.
5. LOW BLOOD SUGAR
Individuals with type 1 diabetes may be at high risk of further episodes of low blood sugar (hypoglycemia), characterized by confusion, shakiness, exhaustion and sweating. Hypoglycemia can lead to coma and death if it is not treated.
They normally experience low blood sugar when they take too much insulin and do not ingest enough carbohydrates and eat too much protein on keto. As a consequence, a low carb keto diet can increase the risk.
6. BONE DAMAGE
A study conducted on 29 children with epilepsy on the keto diet showed that 68% had a lower bone mineral density score after diet.
Another research in 30 elite walkers showed that those who practised keto for 3.5 weeks had substantially higher blood markers for bone breakdown than those who ate higher carbs diets.
Digesting protein releases several acids into the bloodstream, and calcium is required to neutralize them. Eating too much protein on keto can force the system to remove more calcium from the bones and weaken them over time.
A more thorough study is, however, warranted in this area.
7. INCREASED RISK OF EARLY DEATH
Research done in over 130,000 adults related low-carb diets focused on animals or eating too much protein on keto leads to higher rates of death from heart disease, cancer, and all causes.
On the other hand, low-carb vegetable diets have been linked with lower mortality rates due to heart disease and all causes.
8. ALLERGIC REACTIONS
You’ll consume more protein and fat, increasing your consumption of eggs, nuts, whole-grain milk, and other things that you might not have consumed too much before.
Eating new and unusual foods, basically, too much protein on keto can lead to allergic reactions.
Popular causes of food sensitivities include dairy, nuts, eggs and seafood.
9. WORSENS LIVER DISEASE
If you are already dealing with a weakened liver, eating too much protein on keto will contribute to the build-up of harmful toxic waste products in your body.
This is because the liver is unable to absorb all the protein properly. Standard dietary intake levels are good, but if you go overboard, whether with your diet and/or through supplements or protein powders, you will do further harm to your liver.
10. DEHYDRATION
Eating too much protein on keto can increase your thirst. This suggests dehydration and is triggered when the body uses extra fluids to flush out excess nitrogen created by digesting proteins.
HOW MUCH PROTEIN SHOULD YOU EAT A DAY ON KETO?
Your ideal protein intake level is dependent on several factors;
Genetics. Your genetic composition can affect your body’s insulin resistance and sensitivity, as well as your ability to burn ketones for energy. Both can affect your hormonal response to protein intake.
The present structure of the body. The bigger or heavier you are, the more protein you need to eat. If you have a higher body fat percentage, higher protein intakes can cause a sufficient increase in insulin levels to decrease ketone production.
Gender. Women may have a different protein response than men depending on what stage of their cycle they are in.
Insulin sensitivity. Individuals with type 2 diabetes may struggle with ketone output due to higher insulin levels, and protein intake may cause their insulin to increase. On the other hand, healthier and fitter individuals will get away from eating more protein without impairing ketones’ production.
Current calorie and macronutrient intake. Basically, eating fewer carbohydrates and/or calories can keep higher protein intake from reducing your ketone levels.
Duration on the keto diet. The longer you’re on a keto diet, the less likely a higher protein intake will interrupt ketosis.
Activity levels. If you are more active (especially if you lift weights), you will need more protein to restore your glycogen levels and build muscles. You would also need less insulin to make use of the protein. This means that ketone development will continue to be induced even after a high protein meal.
However, with that being said, the process of calculating your protein intake levels should not be complicated by having to take into consideration all the above factors. The following general principles can be used;
- If you are sedentary — consume 0.6 – 0.8g of protein per pound of lean body mass.
- Regularly active — have 0.8 – 1.0g of protein per pound of lean body mass.
- If you lift weights — eat 1.0 – 1.2g of protein per pound of lean body mass.
CONCLUSION
While a keto diet is linked to short-term weight loss and other health benefits. It can contribute to nutritional deficiencies, digestive problems, poor bone health, and other problems over time.
Due to these complications, if you contend with kidney failure, diabetes, heart or bone disease, or other medical conditions, you should talk to your health care provider before you attempt a keto diet.
You will also want to consult a dietitian to prepare healthy meals. Also, monitor your nutrient levels when on this diet to help minimize the risk of complications and nutrient deficiencies.
