Clinical trials: Overfeeding
Overweight and Obesity
Study of the Effects of Overfeeding on Glucocorticoids in Lean and Obese Subjects
Investigators suggest that in lean subjects cortisol increases in response to overfeeding and that this increase is blunted in obese subjects.

Obesity, Normal Physiology
The Effects of Increasing Caloric Intake on Diet-Induced Thermogenesis and 24h Energy Expenditure
Background: Diet-induced thermogenesis (DIT) is the amount of energy one's body uses to eat food, absorb the nutrients from the food, and process those nutrients.

- Obesity, Normal Physiology, Healthy Volunteers
- Trial name
- NCT05545306
- Testing
- +200% of dietary requirements, 50% of calories from carbohydrates, 20% from protein, and 30% from fat, fasting, -50% of energy balance requirements. 50% of calories from carbohydrates, 20% from protein, and 30% from fat
- Where

- Testing
- Eucalaloric feeding, Acute Fasting, Acute Overfeeding

Overfeeding and Exercise
Effect of Exercise and Training on Fat Oxidation During Overfeeding - the FeedEX Study
Rationale: Body weight is not well regulated in all individuals. In an obesogenic environment, where overeating is common, some individuals are more prone to weight gain and therefore overweight than others.
- Trial name
- FeedEX (NCT02333916)
- Testing
- overfeeding + exercise pre-training, fitness training, overfeeding + exercise post-training
- Where
- Netherlands
- Volunteers
- 5 people, healthy volunteers welcome
