What is the purpose of this trial?

This trial examines whether daily self-weighing can help individuals with obesity prevent further weight gain. Participants will receive either standard weight management resources ("Standard Care") or a digital scale for daily self-weighing. The trial aims to determine if daily weight checks can serve as a simple, effective tool for managing obesity. Suitable candidates may have a body mass index (BMI) between 30 and 50, receive care at a participating clinic, and possess a smartphone with internet access. As an unphased trial, this study provides a unique opportunity to contribute to innovative research in weight management strategies.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on prescription weight loss medications, you must not have taken them in the past 6 months to be eligible.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that daily self-weighing is generally safe. Studies have found that this habit does not cause stress or anxiety. In fact, people who weigh themselves regularly often manage their weight better and tend to lose more weight without negative effects. Overall, this practice is well-tolerated and lacks significant downsides. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the Daily Self-Weighing approach for obesity management because it offers a simple, proactive way for individuals to engage with their weight loss journey. Unlike standard care, which typically involves general weight management advice and support, this method empowers participants with immediate feedback through a digital scale. The unique feature here is the promotion of daily accountability and awareness, potentially leading to better long-term weight management. By incorporating technology and daily self-monitoring, this approach could enhance motivation and make weight management more sustainable.

What evidence suggests that this trial's treatments could be effective for obesity management?

This trial will compare daily self-weighing with standard care for obesity management. Research has shown that daily self-weighing can aid in weight loss. Studies have found that this practice encourages better weight control habits and results in more weight loss than weighing only a few times a week. Regular weight checks also help maintain weight loss over time. In various contexts, daily self-weighing has proven effective in improving weight management. This method offers a practical approach to preventing weight gain and managing obesity. ^{3 4 6 7 8}

Are You a Good Fit for This Trial?

This trial is for adults aged 19-65 with obesity (BMI of 30-50) who are patients at participating clinics, live in one place most of the week, and have a smartphone with internet. It's not for those planning to move soon, who've lost significant weight recently or taken weight loss drugs, had bariatric surgery within two years, are pregnant or might become so during the study.

Published Research Related to This Trial

Only 35% of primary care patients with overweight or obesity self-weigh weekly, and less than 23% do so daily, indicating a need for increased awareness of self-weighing as a tool for weight management.

Patients who self-weighed daily had a lower average BMI (29 kg/m²) compared to those who did not (31 kg/m²), suggesting that regular self-weighing may help in preventing obesity.

In a study of 74 adults with overweight and obesity over 12 weeks, it was found that daily self-weighing is an effective strategy for weight loss, with high adherence rates of 87% for weighing and 85% for caloric intake.

The research revealed that increased caloric intake on one day significantly raised the likelihood of not self-weighing the next day, suggesting that weight management programs should offer additional support to participants who overeat to maintain adherence to self-monitoring.

Varenicline is an effective smoking cessation aid that works as a partial agonist at nicotinic acetylcholine receptors, with a standard dosage of 1 mg twice daily for 12 weeks, showing a linear pharmacokinetic profile across various populations including smokers and nonsmokers.

The drug is primarily excreted unchanged in urine and does not significantly interact with other medications, making it safe for use alongside common drugs; however, nausea is the most common side effect, particularly at higher doses.

In a review of ten randomized controlled trials involving 3091 participants, varenicline did not show a significant increase in overall psychiatric disorders compared to placebo, with an incidence of 10.7% in the varenicline group versus 9.7% in the placebo group.

While varenicline was associated with a higher incidence of sleep disorders, there were no reported cases of suicidal ideation or behavior in the analyzed studies, suggesting that varenicline is generally safe for smokers without current psychiatric conditions.

Daily self-weighing was found to be a motivating factor for individuals who successfully lost weight during a 12-month intervention, with participants feeling more in control of their weight management.

The study identified both positive aspects and barriers to daily weighing, suggesting that understanding these factors can help improve adherence to self-weighing as a weight loss strategy.

Phentermine-topiramate extended release (ER) has been shown to help obese individuals lose an average of 10% of their initial weight, which is about 8% more than a placebo, and it also reduces the risk of developing type 2 diabetes and improves cardiovascular disease risk factors.

While effective for weight loss, phentermine-topiramate ER can increase heart rate and poses risks for women of child-bearing age due to potential harm to infants, highlighting the need for careful monitoring and consideration in these populations.

Varenicline, a medication used for smoking cessation, has been linked to serious cardiovascular events, including pulmonary thromboembolism (PTE), which may occur even in patients without pre-existing cardiovascular conditions.

A case report highlighted a probable association between varenicline and PTE, indicating that this adverse effect should be considered when prescribing the medication, especially since the patient had a low risk for such events.

In a study of 12,159 patients, varenicline was associated with reported neuropsychiatric events, particularly anxiety, but no significant increase in these events was found over time, suggesting that the drug's safety profile remains largely stable.

While 7-17% of neuropsychiatric events were attributed to varenicline by general practitioners, the analysis did not raise significant safety concerns, indicating that further investigation is needed to clarify the relationship between varenicline and anxiety symptoms.
