Even the much touted keto doesn’t work for everyone. As Neil Swidey writes in the Boston Globe:
In the low-carb group, some participants lost 40 to 60 pounds while others gained 10 to 20. And in the low-fat group? Just about the same wide variation. Neither diet was better, and researchers had no success in predicting who would do better on one versus the other.
All of this suggests that your co-worker who won’t stop yapping about how keto will change your life might be completely right. Or he could be entirely wrong.

The few things that do seem to work for everyone are to reduce or eliminate added sugar, reduce processed and refined carbs, and eat healthy fats. Everything else seems to be a toss up and depends on personal metabolic traits.
Trial and error will probably be necessary, but by avoiding processed foods (itself a vague term — do bread or pasta count, if we’re being careful to make sure they’re made from whole grains?) you’ll probably be off to a decent start.
