(HDLS2) Trial Summary

This trial will compare the effect of two diets on reducing abdominal fat and liver fat in obese people. One diet is a Mediterranean diet with intermittent energy restriction, and the other is a daily energy-restricted diet. The trial will recruit 312 people and randomize them to the two diets. The primary research question is whether the intermittent energy restriction diet will be superior to the daily energy restriction diet in reducing abdominal and liver fat.

Who is the study for?
Adults aged 35-69 with a BMI of 25-40 and abdominal obesity (VAT ≥90 cm2 for men, ≥80 cm2 for women), who are non-smokers, drink little alcohol, have no serious health issues or recent substantial weight changes. Must be East Asian, Native Hawaiian/Pacific Islander or White ethnicity and fully vaccinated against COVID-19.Check my eligibility
What is being tested?
The study is testing whether combining Intermittent Energy Restriction (IER) with the Mediterranean diet (MED) is more effective than daily energy restriction (DER) with MED in reducing belly fat and improving cancer-related markers over six months.See study design
What are the potential side effects?
Potential side effects may include discomfort from fasting on IER days, possible nutritional deficiencies if not properly monitored, and general challenges associated with dietary restrictions such as hunger or fatigue.

(HDLS2) Trial Design

2Treatment groups
Experimental Treatment
Group I: Mediterranean diet (MED) + daily energy restriction (DER) or MED/DERExperimental Treatment1 Intervention
The MED/DER group intervention will restrict 20% energy (25%, 45% and 30% distribution of protein, carbohydrate, and fat, respectively) continuously. Participants will also be asked to follow a moderate exercise program (1 hour of walking five days a week).
Group II: Intermittent energy restriction (IER) + Mediterranean diet (MED) or IER+MEDExperimental Treatment1 Intervention
The IER+MED group intervention will be to restrict 70% energy (25%, 45% and 30% distribution of protein, carbohydrate, and fat, respectively) on 2 days and follow a MED diet (25%, 45%, 30%) and meet their estimated energy requirement (EER) for the other 5 days each week. This would be equivalent to an over-all 20% daily energy restriction. Participants will also be asked to follow a moderate exercise program (1 hour of walking five days a week).

What objectives does this scientific research endeavor to fulfill?

"This clinical trial, which will be monitored until Week 24, has the primary goal of measuring total adiposity via Dual-energy X-ray absorptiometry (DXA) scan. Secondary objectives include assessing body weight at week 48 post trial to evaluate if the IER+MED diet plan is more effective than MED/DER in sustaining long term weight loss; determining BMI levels upon completion of the study to determine if IER+MED can reduce bodyweight better than MED/DER; and taking waist & hip circumferences measurements 24 weeks after the end of the trial to check whether or not IER+MED improves longterm weight"

Why did patients apply to this trial?

I have tried many ways to lose weight. I am interested in your study and can travel.
PatientReceived 1 prior treatment
I've been trying for 20+ years to lose weight...fad diets, exercise, lifestyle changes, doctors, weight loss programs, pills, etc. Some methods worked better than others but I have never come close to achieving my goal weight. While I have been able to lose over 100lbs over a 4 year period, I am still struggling, and am, in fact, gaining again. The excess weight is affecting my daily life like it never has before and I need help.
