People logging food daily on personalized diets lost no more weight than those on standard plans—even when their meals were tailored to their DNA. One study found identical HbA1c drops between custom and generic low-fat diets, despite twice the effort.
There's disagreement
Studies point in different directions — there's no clear consensus yet.
Custom diets might seem like a magic bullet, but the science isn’t as clear-cut as the post claims.
Some studies show that people on personalized diets did lose more weight and lower their blood sugar better than those getting general advice, which sounds promising. But other research found no real difference — people on standard healthy diets improved just as much, even without fancy personalization. One even found that people who logged their food more often still didn’t lose more weight on a custom plan. The results aren’t consistent, and it’s not clear if the extra effort and cost of personalization are worth it for most people.
Personalized diets aren’t a guaranteed win — for many, a simple, healthy eating plan might work just as well.
