Pattern 10 / 12 Otto observes
Protein at breakfast → fewer afternoon cravings
The 5pm sugar craving does not come from tiredness. It comes from a breakfast that did not set the satiety signal early enough.
A breakfast with at least 25–35 g of protein tends to significantly reduce afternoon cravings and sugary snacks the same day. The effect is independent of total caloric intake — protein at the first meal shifts the hunger curve for the entire day.
Leidy et al. (2013) · Am J Clin Nutr
Crossover RCT (n=20 overweight adolescent girls who usually skipped breakfast): a 35 g protein breakfast (eggs + lean meat) reduced evening snacking vs. skipping. Brain activity in regions controlling cravings dropped in parallel with rising satiety.
Dalgaard et al. (2024) · J Dairy Science
3-period crossover RCT (n=30 young overweight women): a high dairy-protein breakfast increased satiety over 3 hours post-meal vs. an isoenergetic high-carb breakfast or skipping. Pre-lunch cognitive concentration was 3.5 percentage points higher.
Qiu et al. (2021) · Nutrients
Meta-analysis of RCTs in children and adolescents (10 studies): a high-protein breakfast reduced subsequent caloric intake by about 110 kcal, increased satiety and reduced hunger vs. a normal-protein breakfast or skipping. The effect carried over into reduced subsequent caloric intake.
Protein at breakfast stimulates the release of PYY and GLP-1 — satiety hormones that tell the brain "enough" over 4–5 hours. With simple carbs in the morning, those signals are weak and short.
On top of that, protein in the morning buffers glucose spikes across the rest of the day — even after later carb-heavy meals. Glucose stability at 4–5pm depends, in part, on what you ate at 8am.
If you skip breakfast, the craving-control signal only starts after lunch — and from 2pm on, you are catching up on the entire morning.
Protein per meal and hourly distribution (NutriBase) + food entries in the 2pm–7pm window, particularly sugary snacks.
Target: 25–35 g of protein at breakfast. That is 3 eggs + Greek yoghurt, or 200 g cottage cheese, or a 2-egg omelette + 50 g ham, or 200 g Greek yoghurt + 30 g nuts.
Otto shows you the correlation: days with morning protein × afternoon snack frequency. Within 10–14 days the pattern tends to become visible — on your own data.
