The emphasis is clearly on building lean muscle mass, improving body composition, and enhancing metabolic efficiency. This is a crucial distinction because it shifts the conversation from quick facial fixes to long-term physiological change,” said Goyal. Do you work out regularly?

Strength training plays a significant role in this process by increasing muscle mass, which in turn improves metabolic rate and supports sustainable fat loss,” said Goyal.

Poor posture often leads to a forward head position, making the jawline look less defined, whereas improved alignment creates a more structured and lifted facial profile,” said Goyal.Also Read | Namita Thapar, 48, reveals her six-month struggle with a frozen shoulder and menopause: ‘But baby, I’m back!What to note?A combination of strength training, balanced nutrition, reduced inflammation, and proper hydration is what ultimately reflects on the face. “Diets rich in high-quality protein, antioxidants, and anti-inflammatory nutrients help reduce puffiness and support fat loss, both of which are essential for achieving that sculpted look,” said Goyal.Story continues below this adDISCLAIMER: This article is based on information from the public domain and/or the experts we spoke to.
