The Study
The effects of cultured dairy and non-dairy products added to breakfast cereals on blood glucose control, satiation, satiety, and short-term food intake in young women.
This study found that when young women ate yogurt with cereal, their blood sugar went down more than when they ate coconut yogurt with cereal — but we can’t say for sure that the yogurt caused it, because we don’t know if they knew which one they were eating. It’s like seeing that your friend feels better after drinking tea — maybe the tea helped, or maybe they just felt better because they thought it would.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Two kinds of breakfasts with granola were tested: one with yogurt (high protein) and one with coconut (high fiber). Both made people feel full and eat less after 2 hours than if they skipped breakfast. But the yogurt one made blood sugar drop more because it made the body release more insulin.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — eating yogurt breakfast may help control blood sugar better than coconut breakfast without making people hungrier or eat more later.
- 2Yogurt breakfast: 52% lower blood sugar spike, 3× more protein, 4× less fiber than coconut breakfast.
- 3Both breakfasts made people eat less in the next 2 hours than skipping breakfast.

After eating yogurt with cereal, young women’s bodies released almost twice as much insulin as after eating coconut-based cereal, which likely helped lower their blood sugar without making them hungrier later.
Young women who skipped breakfast ended up eating less overall in the next two hours than those who ate either yogurt or coconut cereal — which seems surprising, but the study found it.
Yogurt with cereal gave young women three times more protein and only a quarter of the fiber compared to coconut cereal — even though both meals had almost the same calories and carbs.
Whether young women ate yogurt with cereal or coconut-based cereal for breakfast, both made them feel less hungry and eat less in the next two hours than if they hadn’t eaten breakfast at all.
Delayed protein consumption due to breakfast skipping results in elevated total daily caloric intake due to prolonged appetite drive until protein satiety thresholds are achieved.
When young women ate yogurt with cereal for breakfast, their blood sugar stayed much lower after eating than when they ate a coconut-based cereal breakfast.
