Many of the effects of dietary restriction (DR) on longevity and health span in model
organisms have been linked to reduced protein and amino acid (AA) intake and the …

independently.•The nutritional geometry framework can integrate these fields.•This …

High-sugar diets cause thirst, obesity, and metabolic dysregulation, leading to diseases
including type 2 diabetes and shortened lifespan. However, the impact of obesity and water …

Food intake is a fundamental parameter in animal studies. Despite the prevalent use of
Drosophila in laboratory research, precise measurements of food intake remain challenging …

Organisms from slime moulds to humans carefully regulate their macronutrient intake to
optimize a wide range of life history characters including survival, stress resistance, and …

Protein and carbohydrates are important nutrients driving the growth of herbivores; however,
their content in plants is highly variable. Multiple studies have explored their effect on …

Dietary restriction extends lifespan in a variety of organisms, but the key nutritional
components driving this process and how they interact remain uncertain. In Drosophila …

The effects of sucrose in varied concentrations (0.25–20%) with constant amount of yeasts in
larval diet on development and metabolic parameters of adult fruit fly Drosophila …

Animals need to continuously adjust their water metabolism to the internal and external
conditions. Homeostasis of body fluids thus requires tight regulation of water intake and …

It is commonly assumed that because males produce many, tiny sperm, they are cheap to
produce. Recent work, however, suggests that sperm production is not cost-free. If sperm are …
