^^ speaking of simple tweaks
Shadi ke baad jab puri tarah se joint family mein shift huye toh sabse pehle my better half changed all Commode setup to squatting, not just our but sabka except parents. Sahi wala kalesh hua tha lol but now when i look at this past event, it looks like one of the fine and simple lifestyle change.
Shaadi k baad kalesh na ho toh zindagi ke kya majje. Indian toilet is good for us but as we grow older our knees tend to get weak.
That is where wester commode helps us by easing the pressure on our knees and so both the commodes are equally important.
Most of the Indians used to be farmer like 100 years ago so they just keep working most of their days that just burned them enough colories so the rich carb foods we took was good but now we are all working in airconditioned room and sitting at the desk all day that is drastic difference in physically demanding works yet we used to the same food culture that made our bellies bigger.

Gym is good but not necessary for everyone, simple tweaks in the lifestyle can get us in shape, I guess, walking, cycling over using bikes for shorter distances, waking up early, don't skip breakfast, light lunch and finish dinner at least before 7pm.
That is it. That is what we need to know. Our lifestyle impacts a lot on our body. What we eat is what we transform our body into.
Healthy food and a balanced diet is a must depending on what type of work we do.
Most of us have a desk job which requires less calories and our diet should replicate the same so that we don't get obese.
