Time Restricted Eating for Weight Loss Maintenance
(TWIST Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how two different time-restricted eating (TRE) schedules can help people maintain weight they have already lost. Participants will eat within either a 6-hour or a 10-hour window each day. The study seeks individuals who have recently lost at least 5% of their body weight without surgery and typically eat over more than 12 hours a day. As an unphased trial, it offers a unique opportunity to contribute to innovative research on weight maintenance strategies.
Do I need to stop taking my current medications for the trial?
You may need to stop certain medications to join the trial. If you are on appetite suppressants, anti-obesity medications, or medications expected to cause weight loss, you might need to delay treatment with these for the next 3 months.
What prior data suggests that this time-restricted eating method is safe for weight loss maintenance?
Research has shown that time-restricted eating (TRE) is generally safe for people. Studies have found that eating within a set number of hours each day, such as 6 or 10 hours, does not negatively affect diet quality. In fact, these eating patterns can aid in weight loss and promote a healthier body. For instance, one study found that eating within a 10-hour window helped participants lose weight, lower blood pressure, and reduce harmful blood fats, which can lead to heart problems.
Short-term studies also indicate that TRE is safe and easy for healthy adults to follow. Participants in these studies did not experience any serious side effects. Instead, they benefited from weight loss and reduced body fat over time. This suggests that TRE can be a safe option for those aiming to maintain weight loss.12345Why are researchers excited about this trial?
Researchers are excited about time-restricted eating (TRE) for weight loss maintenance because it offers a fresh approach compared to traditional calorie counting or dietary restrictions. TRE allows individuals to eat freely within a specific time window, like 10 hours (TRE10) or even just 6 hours (TRE6), which can be more manageable and sustainable for many people. Unlike typical diets that require constant monitoring of food intake, TRE focuses on when you eat rather than what or how much, potentially making it easier to maintain long-term. This method could simplify weight management by aligning eating patterns with the body's natural circadian rhythms, which might enhance metabolism and promote better overall health.
What evidence suggests that this trial's time-restricted eating interventions could be effective for weight loss maintenance?
Research has shown that time-restricted eating (TRE) can help people maintain weight loss. Studies have found that TRE can lead to modest weight loss, with some individuals losing and keeping off 5-10% of their body weight over a year. In this trial, participants will follow different TRE schedules: one group will eat within a 10-hour window, which earlier studies showed can lead to a 3% weight loss after 12 weeks, while another group will eat within a 6-hour window. TRE has also reduced waist size and improved body mass index, a measure of body fat based on height and weight. Overall, TRE aids in weight management by helping people eat fewer calories and improving health indicators.46789

Trial Overview
The study tests two time-restricted eating plans for maintaining weight loss: one group eats within a 6-hour window (TRE6), the other within a 10-hour window (TRE10). Participants will be randomly assigned to these groups and monitored over a period of up to three months.
