I've tried starving before myself—I got dizzy and couldn't focus on work. Based on that experience, I know men especially fear muscle loss. Korean medicine diet works by boosting metabolism, not just reducing food intake. It helps remove 'dam-eum' (phlegm and fluid retention, accumulated waste) so energy flows better. For those too exhausted to exercise, we supplement 'bi-heo' (spleen deficiency, weakened digestive function) to revive vitality—this is very effective. However, there are downsides: depending on your constitution, some may experience insomnia or palpitations from the herbs. Also, relying solely on medicine can make you miss the right timing to correct your eating habits—you must be careful. So it's hard to say what's 'best' in absolute terms. Some need strong appetite suppression, others need to reduce edema and first resolve 'eo-hyeol' (blood stasis, stagnant blood). I recommend we first examine your current body condition, then build a customized strategy together.
