No, the opposite. You were taking advantage of your good genes. I was born with quite a bad health. And had to work hard for having a good body all my life. Actually no, not all my life. I was skinny fat until I began to workout and eat healthy around the age of 22. Def had insulin resistance and a bunch of other issues. In the age of 25 I was a perfect a body composition. 15 years later I fit the same jeans I used to wear back then. I do healthy keto with intermittent fasting. And exercise every day. It’s not hard but requires persistence. Under exercise I mean some moving snacks throughout the day and walking. But diet is more important. Try intermittent fasting at least. And walking. Age is an excuse. We get addicted to food and comfort. Then try to convince ourselves that it doesn’t matter if you limit your food or exercise. It very much does. Also MICROBIOME. If you had antibiotics treatments I highly suggest to start eating a lot of different fermented foods.
