📝 Detailed Answer
I have personally experienced the pitfalls of extreme fasting and one-food diets, which left me feeling so dizzy that daily activities became impossible. Through that experience, I recognized that shakes offer the distinct advantages of 'convenience' and 'calorie control,' making them an attractive option for busy professionals.
However, there are drawbacks. It is difficult to obtain all essential nutrients from processed powders alone. Specifically, those with weak digestive systems may experience bloating or enter a state of 'Bi-heo' (脾虛), where the spleen's function is diminished, leading to a significant drop in energy. This can lower your basal metabolic rate, making long-term weight loss even more difficult.
Furthermore, toxins such as 'Dam-eum' (痰飮, accumulated phlegm-fluid) and 'Eo-hyeol' (瘀血, blood stasis/stagnant blood) are not eliminated simply by reducing calories. If you fast without properly discharging these metabolic wastes, your body will continue to feel heavy and sluggish.
Ultimately, the answer depends on your situation. Shakes can be helpful for immediate dietary management, but for long-term success, it is far healthier to combine balanced meals with TKM herbal medicine tailored to your constitution to boost metabolism. I suggest we first evaluate your current physical state together before deciding on the best approach.
