THE KETO DIET EXPLAINED BY AN EXPERT: BETWEEN REAL EFFECTS AND NECESSARY PRECAUTIONS

This ultra-popular diet is not a fad: the opinion of the president of the Order of Biologists of Lombardy

Very popular in recent years, the ketogenic diet continues to appeal to many people looking for rapid weight loss. But be careful: this very restrictive diet is not without risk. Rudy Alexander Rossetto, president of the Order of Biologists of Lombardy (Italy), enlightens us on the functioning, the advantages, the dangers and the errors to avoid with this very specific dietary protocol.

What is the ketogenic diet?

It is based on one principle: drastically reduce carbohydrates (< 50 g/day), in order to force the body to draw on its fat reserves as a source of energy. This causes a condition called ketosis, which causes the liver to produce ketone bodies, used as an alternative fuel by the brain and muscles.

✅ Advantages and ❌ Disadvantages

✅ Benefits ❌ Disadvantages
Rapid weight loss thanks to lower insulin and increased fat utilization Difficult to follow over the long term, can cause fatigue and irritability
Reduced appetite thanks to ketone bodies Risk of nutritional deficiencies (fiber, vitamins, minerals) if poorly balanced
Improved insulin sensitivity (useful for obesity, type 2 diabetes, PCOS) Possible impact on the intestinal microbiota and imbalance of the bacterial flora
Potential positive effects on migraines and epilepsy Possible side effects: nausea, headache, muscle cramps (keto flu)
May help manage metabolic syndrome Not recommended in cases of kidney, hepatic or cardiovascular disorders

In which cases is the ketogenic diet indicated?

It can be beneficial in the following cases:

  • Overweight, obesity, insulin resistance
  • Type 2 diabetes (under medical supervision)
  • Polycystic ovary syndrome (PCOS)
  • Drug-resistant epilepsy (especially in children)
  • Chronic migraines (with emerging scientific evidence)

And the contraindications?

The ketogenic diet is not recommended:

  • In case of liver or kidney failure
  • For people suffering from lipid metabolism disorders
  • For pregnant or breastfeeding women
  • In the event of type 1 diabetes (except expert monitoring)
  • In case of eating disorders

Example of daily menu (strict version)

  • Breakfast : egg white omelette + green vegetables + 5-6 almonds
  • Snack : plain Greek yogurt + flax seeds
  • Lunch : grilled chicken fillet + sautéed zucchini + olive oil
  • To taste : 50 g lean ricotta + bitter cocoa
  • Dinner : white fish + spinach + olive oil

Recommended duration and work-study advice

A strict ketogenic diet should ideally last 4 to 5 weeks. Cycles like 5+2 (5 days keto / 2 days moderate carbohydrates) or intermittent keto are recommended to avoid stagnation and long-term side effects.

As Rudy Rossetto recalls: “The ketogenic diet does not replace the Mediterranean diet. It is a tool, not a miracle solution. » Before you start, it is essential to consult a health professional to adapt this diet to your profile and avoid unnecessary complications.
