Hypothesis
To compare the effects of low versus recommended levels of dairy intake on weight maintenance and body composition subsequent to weight loss.
Conclusion
Weight maintenance was similar for low and recommended dairy groups, but the recommended dairy group showed greater fat oxidation and could consume more energy without gaining weight.
Supporting Evidence
- Participants consuming recommended dairy had greater energy intake without weight gain.
- The recommended dairy group showed greater fat oxidation compared to the low dairy group.
- Weight maintenance was similar across both dairy intake levels.
- Significant site interaction indicated different outcomes based on location.
- Recommended dairy intake led to a decrease in plasma 1,25-(OH)2-D levels.
Takeaway
Eating more dairy doesn't make you gain weight after losing it; in fact, it might help you burn fat better.
Methodology
A 9-month randomized trial comparing low dairy (<1 serving/day) and recommended dairy (>3 servings/day) diets after a weight loss program.
Potential Biases
Potential bias from participant and staff blinding during the weight loss phase.
Limitations
Participants were self-reported and may have under-reported energy intake.
Participant Demographics
Participants were 40.3 years old on average, with a BMI of 34.5, and included 79% Caucasian, 15% Hispanic, 5% African American.
