Google AI : Based on current scientific research, there is no reputable study that says general seasoning or spices remove muscle mass. In fact, research generally suggests the opposite: culinary spices and herbs are considered beneficial for muscle health, performance, and recovery. 

ResearchGate  +3 Here is a breakdown of what the research actually says: Spices Help Retain Muscle: Spices like turmeric (curcumin), garlic, ginger, and cinnamon have anti-inflammatory and antioxidant properties that help reduce muscle fatigue, decrease soreness (DOMS), and speed up recovery. Chili Protects Muscles: A study on older adults found that higher consumption of chilies was associated with a lower risk of sarcopenia(age-related muscle loss). Improved Protein Consumption: Adding spices to food increases the enjoyment and consumption of protein-rich meals, which helps maintain muscle mass, especially in older adults. Bodybuilding Context: Extreme bodybuilders sometimes avoid seasoning during the final 36–48 hours before a show to manipulate sodium and water levels for extreme definition, but this is a temporary, elite-level strategy, not a long-term muscle-loss issue. 

ResearchGate  +4 It is possible the idea you heard stems from extreme "clean eating" culture, where individuals avoid all seasoning to eliminate sodium (salt) to prevent water retention, or due to a misunderstanding of how certain herbs might impact hormone regulation.
