I have personally tried various trending diets in the past and experienced the 'brain fog' and exhaustion that can come with trial and error. The primary advantage of a ketogenic diet is that by restricting carbohydrates, it lowers insulin levels and increases the efficiency of fat burning, making appetite control relatively easier. However, there are clear drawbacks from a TKM perspective. A sudden high-fat diet can place a significant burden on those with Spleen Deficiency (Bi-heo, 脾虛). When digestive function is impaired, it can lead to abdominal bloating and a feeling of heaviness. Furthermore, those with an accumulation of Phlegm-Fluid (Dam-eum, 痰飮)—metabolic waste products—may experience sluggish blood circulation and severe lethargy during the initial stages. Ultimately, the core issue is whether your body can handle this specific dietary regimen. While it may be the optimal method for some, it could be detrimental to others. Rather than following the trend blindly, I suggest first checking your digestive capacity and the presence of Blood Stasis (Eo-hyeol, 瘀血) or Phlegm-Fluid. By supplementing your diet according to your specific constitution or combining it with TKM treatments to replenish deficient Qi, you can reach your goals much more comfortably. Instead of struggling alone, let's find a customized approach together.
