I used to be naturally slim.
Teased and all. Always heard comments about my waist.
I never put any conscious effort into it Or thought and I assumed that it was just genetics and . Until I had a massive lifestyle change one day and my weight started to creep up. My massive lifestyle change was due to me falling in love with my now DH who is sedentary and junkie.
I was shocked with how much time he spent sitting down. How much junk food he ate. TAke always. Fatty food.
But he was a good weight because he specifically exercised.. unlike me, who never allocated time to go to gym or exercise.
So my weight creeped up by 10kg over a short period.
I then realized that although I never put the “conscious thought” into it, I however had a very healthy lifestyle.
I didn’t crave junk food on a daily basis, only on occasions. I didn’t like sitting on the desk for too long. I like to walk to places to get my stuff and so if it’s a bus journey of 20 mins I just don’t see the need to catch a bus..
It’s probably the way I was raised. Very active childhood. Hardly any screen time.. so sitting down still was the opposite of quality time for me.
So I really think the “naturally slim” are just “naturally active” without the gym.
I also hardly craved food.. I was too active to think about food. Only ate when I was starving which was about twice a day tops.
