This trial investigates whether a low-ED diet helps people keep weight off better than an energy balance diet.

Who is the study for?
This trial is for adults aged 18 to 70 with a BMI between 27 and 45, indicating overweight or obesity. It's designed for those who are interested in maintaining weight loss through specific dietary strategies.Check my eligibility
What is being tested?
The study compares two diet-based approaches to keep weight off: one group will eat foods low in energy density (low-ED), while the other will balance daily calorie intake with their estimated needs for maintenance (energy balance).See study design
What are the potential side effects?
Since this is a dietary intervention, side effects may include changes in digestion, potential nutrient deficiencies if not properly managed, and possible initial hunger or dissatisfaction as participants adjust to new eating patterns.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Low-EDExperimental Treatment1 Intervention
This condition will focus lowering on the energy density of the diet of the diet. This prescription does not include goals for any other nutrients, thus there are no energy goals.
Group II: Energy BalanceExperimental Treatment1 Intervention
This condition will focus have an energy balance prescription. Participants will be asked to consume a daily energy intake at estimated energy needs for weight loss maintenance.
