Yeah, in most weight loss studies, just about every deficit group gets results on basic things like weight lost and waist measurements. They often throw in a “don’t change anything” control group, but it’s not even necessary really. The real fun comes with blood tests, DEXA scans, metabolic rate testing, and follow-ups weeks, months, or even a year later.
I have a few more nutrition and fat-loss articles that really dig into some interesting studies. This one is wild: The Most Effective Diet You Should Never Do.
