A ketogenic diet (carbohydrate restriction <50g/day) promotes weight loss and visceral adiposity reduction by inducing nutritional ketosis, which suppresses appetite via beta-hydroxybutyrate (BHB) signaling and increases energy expenditure through fat oxidation.
To use this diet, restrict carbohydrates to under 50 grams per day (under 20g for therapeutic effects). Focus on healthy fats and moderate protein. Expect initial weight loss and reduced hunger due to ketone production. Monitor your progress with blood ketone levels (0.5-3.0 mmol/L) to ensure you are in ketosis.
GoodSupportsHIGH confidence
Ketosis is normally achieved through either fasting or carbohydrate restriction... Only when a patient restricts carbohydrates to less than 50 g/day will the body be incapable of fueling the body by glucose and will switch to burning fat... research suggests that β-hydroxybutyrate acts as a signal molecule and may play a role in suppressing appetite... The results showed that a state of ketosis increased energy expenditure (~100 kcal/d), most likely due to beta oxidation and the partitioning of fuel towards ATP production rather than fat storage.
Why this rating
The paper is a narrative review citing multiple RCTs and meta-analyses, though it acknowledges the need for more long-term studies.
