The Claim
Food restriction in rats is associated with decreased serotonin levels in the raphe nuclei.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Rats that are fed less food show lower levels of serotonin in a specific brain region called the raphe nuclei.
See the scientific wording
Food restriction in rats is associated with decreased serotonin levels in the raphe nuclei, suggesting a neurochemical alteration linked to prior nutritional deprivation.
When rats eat less food, their brains get less of the building block needed to make serotonin, so serotonin levels drop in the area that controls hunger and mood. When they start eating again, the brain breaks down the remaining serotonin faster, which may help reset how the brain responds to food.

1 studyStudy: Effect of starvation or restriction on self-selection of macronutrients in rats.
When rats didn't get enough food, their brains showed less serotonin in the area that controls mood and hunger — exactly what the claim says.
