After following different diets for 18 months, people who ate a green-MED diet (with extra plant-based shakes and green tea) had a bigger increase in their hunger hormone levels compared to those on standard healthy eating guidelines.
Scientific Claim
Fasting ghrelin levels increased by 1.3%, 5.4%, and 10.5% in healthy dietary guidelines, Mediterranean diet, and green-MED diet groups, respectively, after 18 months of weight loss, with the green-MED diet showing a significantly greater increase compared to healthy dietary guidelines.
Original Statement
“After 18 months of moderate and similar weight loss among the MED groups, FGL increased by 1.3%, 5.4%, and 10.5% in HDG, MED, and green-MED groups, respectively (P = 0.03 for green-MED vs HDG); sex-stratified analysis revealed similar changes in men only.”

Assessment Explanation
The abstract explicitly reports the percentage increases and statistical significance (P=0.03), so definitive verbs are appropriate for stating the observed data.

Diet-induced fasting ghrelin elevation reflects the recovery of insulin sensitivity and visceral adiposity regression.
