You're absolutely right, though - think about who you see promoting diets. It's always someone with a book or TV show, or YouTube channel, or Instagram. Always someone with financial interests.

Dieting is as simple as you state: calories in, calories out. Cut too much, and your body doesn't get what it needs. Cut the fun stuff too hard, and you end up craving and gorge too hard when you get the opportunity.

A bit of chocolate or beer doesn't hurt you, so don't forget to have your indulgences where you can. Life's too short to ingest salad and sunshine for life.
