Clinical trials: Overfeeding, open to volunteers
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.

Liver Fat, Cardiac Function
Short-term Fat Overfeeding on the Effects of Liver Metabolism
Despite work showing the overconsumption of saturated fatty acids (SFA) to be metabolically deleterious, debate continues about whether there is a link between SFA and cardiovascular disease risk.

Obesity & Overweight
Changes in Intestinal Permeability and Systemic Inflammation Following Fast Food Overfeeding.
The purpose of this study is to investigate whether lifestyle factors can alter gut barrier integrity and whether disruptions of the gut barrier can trigger systemic and tissue-specific inflammation.

Obesity
Thermogenenic Responses to Fasting and Overfeeding in Women
This study plans to learn more about why menopause increases the risk of weight gain. During and after menopause, women are prone to increased weight gain.
- Trial name
- NCT06610162
- Testing
- Eucalaloric feeding, Acute Fasting, Acute Overfeeding
- Where
- United States
- Volunteers
- 56 people, healthy volunteers welcome
- Sponsor

Overweight and Obesity, Metabolic Syndrome
Testing the Adipose Expandability Hypothesis In Vivo During Overfeeding
Adipose, or fat, tissue is a plastic organ that retains the ability to expand and store excess calories during positive energy balance in humans.
- Trial name
- EAT 2 (NCT04583514)
- Testing
- Control, Overfeeding
- Where
- United States
- Volunteers
- 58 people, healthy volunteers welcome

Lipid-induced Insulin Resistance
Overfeeding Induced Fat-tissue Stimulation
Type 2 diabetes is the most common metabolic disease worldwide, characterized by hyperglycemia, decreased whole body insulin sensitivity, and white adipose tissue (WAT) dysfunction.
