Energy balance
A dose-response relationship exists between reduced caloric intake and weight/BMI loss, where every 100 kcal/day decrease is associated with 0.16 kg weight loss and 0.06 kg/m2 BMI decrease.
To lose weight, focus on reducing your daily caloric intake by small, manageable amounts. The study shows that cutting just 100 calories a day leads to a measurable decrease in weight (0.16 kg) and BMI (0.06 kg/m2) over 12 months. This suggests that small, consistent changes are effective for weight management.
with every 100 kcal/day decrease, we observed a 0.14 ± 0.05 kg weight loss (p = 0.004)... with every 100 kcal/day decrease, BMI decreased 0.06 ± 0.02 kg/m2 (p = 0.002).
Why this rating
Statistically significant dose-response analysis in a randomized trial, though the absolute weight loss was modest.
