Meanwhile,
I went ketogenic diet mediterranean:
After 50 years, our metabolism changes and our nutritional needs are evolving. Consequently, The ketogenic diet. Consequently, characterized by a very low carbohydrate content and a high proportion of lipids, arouses growing interest in the fifties in search of weight loss. Therefore, But is it really a good idea to adopt this controversial diet after fifties? Moreover, A recent study published in Science Advances in May 2024 seriously questions this practice, revealing accelerated cell aging in subjects tested.
What is the ketogenic diet and why does it attract those over 50? – I went ketogenic diet mediterranean
The ketogenic diet is based on a specific distribution of macronutrients: around 70-80% lipids. For example, 15-20% protein and only 5-10% carbohydrates (less than 50g per day). However, This carbohydrate restriction forces the body to draw from its fat reserves. In addition, produce ketone bodies as a source of alternative energy.
After 50 i went ketogenic diet mediterranean years, weight loss often becomes more difficult due to the metabolic slowdown. In addition, The ketogenic diet then appears to be an attractive solution, promising quick results without feeling of hunger. Consequently, Some studies actually show slightly higher weight loss compared to fat-free diets (+0.9 to 2.2 kg over 12-24 months).
The reverse of the medal: cardiovascular risks and cellular aging – I went ketogenic diet mediterranean
Recent data is worrying. An analysis of the Biobank UK relating to 305 people following an ketogenic diet has demonstrated a doubling of the risk of cardiovascular events (infarction. stroke) over a period of almost 12 years, compared to the control group.
Even more alarming. the study published in Science Advances in May 2024 reveals that the ketogenic diet significantly accelerates cellular senescence in the heart and kidneys after only 7 to 21 days of experimentation. These results. although obtained on animal models, raise serious questions about the long -term security of i went ketogenic diet mediterranean this diet, particularly in people whose organs are naturally less resilient with age.

Effects on diabetes. metabolism after 50 years
One of the arguments in favor of the ketogenic regime is its positive effect on sensitivity to insulin. Some research effectively suggests improving insulin resistance through ketosis, with activation of genes regulating pancreatic cells.
However. these benefits must be balanced with the longevity secrets of the blue areas, where there are exceptionally low diabetes -free levels without drastic carbohydrates, but rather thanks to a balanced and varied diet.
Practical challenges: grip. quality of life
The abandonment rates oscillate between 13% and 84% depending on studies, testifying to the difficulty in maintaining this restrictive regime. After 50 years. several factors still complicate membership:
- Frequent digestive disorders (constipation, diarrhea)
- Social constraints limiting interactions around meals
- Increased risk of nutritional deficiencies
- Potential impact on muscle mass already naturally declining
What the 2024 study reveals on cellular aging
The study by the i went ketogenic diet mediterranean UT Health San Antonio in 2024 sheds crucial light. The researchers observed that the ketogenic diet induced oxidative stress and an accumulation of cellular damage linked to prolonged ketosis. These mechanisms significantly accelerate the aging of cardiac and renal cells.
These results are particularly worrying for people over 50, whose cellular regeneration capacities are naturally reduced. The lack of decline in long -term mortality reinforces these concerns.
Safer alternatives after fifties
Current data suggest that the Mediterranean diet offers a better balance between efficiency. safety for those over 50. Rich in fruits. vegetables, whole grains, fish and olive oil, this food mode has proven cardiovascular benefits without the risks associated with ketosis.
For those who wish to explore the ketogenic diet. a cyclic approach alternating periods of ketosis and more balanced food phases seems more prudent to maintain its daily energy while limiting cellular risks.
Practical advice if you are considering the ketogenic diet after i went ketogenic diet mediterranean 50 years
If despite these warnings you want to test this approach. here are some essential precautions:
- See your doctor imperatively before you start
- Favor unsaturated fats (avocado, olive oil, fatty fish)
- Complete in electrolytes and fibers to optimize digestion
- Perform regular monitoring of your blood settings
- Plan regular breaks in your diet
- Maintain suitable physical activity, essential after 50 years
In conclusion, if the ketogenic diet can offer rapid results, the cardiovascular and cellular risks it involves makes it problematic as long -term nutritional strategy after 50 years. Traditional food approaches such as the Mediterranean diet. scientifically validated to prevent or manage type 2 diabetes and cardiovascular disease, remain the most careful and effective options to age in good health.
