Answer

Ekasana for 51 days can bring both physical and spiritual changes. Your body may feel:

• Lighter and less sluggish
• Better control over hunger
• Improved discipline in eating
• More awareness of food and cravings
• Possible weight reduction, if your total food intake has become less

But the exact change in body depends on:

• your height
• your food quality
• your portion size
• your activity level
• your body constitution

So with a current weight of 110, the effect may be different for every person.

Explanation

In Jain practice, ekasana is not only about eating once a day. It is also a form of tapasya and self-restraint.

Common changes people notice after some days:

• The stomach feels lighter
• The mind becomes a little more focused
• There is less attachment to taste
• Eating becomes more sattvic and mindful
• The body starts adapting to a simpler routine

Sometimes weight goes down, sometimes it stays the same, and sometimes the person simply feels more balanced. That is normal.

Spiritual Understanding

In Jain Dharma, the real benefit of ekasana is not only bodily change. The deeper benefit is:

• control over desires
• reduction of indulgence
• increase in vairagya
• growth of self-discipline
• purification of mind and conduct

If done with proper भावना, ekasana becomes a beautiful support for tapas, samyak bhav, and inner strength.

Takeaway

For 51 days of ekasana, your body may feel lighter and more disciplined, and your weight may change depending on your body and food intake. But the greatest change is usually within the mind and spirit.

If you want, I can also tell you the likely physical changes week by week during 51 days of ekasana in a simple way.
