ZDNET Author Loses 100 Pounds in 7 Months With GLP-1 and $110 Smart Scale

Q: Beyond the high-tech gear and medication, what was the single most crucial habit for keeping 100 pounds off?

The single most crucial habit was consistent self-monitoring through daily weigh-ins. In the ZDNET contributor’s own account, the weight stayed off for six months because he kept weighing himself every day, alongside maintaining healthier eating and regular activity. The smart scale and apps helped, but the key behavior was the routine itself: checking weight daily, watching trends, and responding early if the numbers started to drift. That aligns with broader expert guidance on long-term weight maintenance. Research and clinicians consistently point to self-monitoring as one of the strongest predictors of keeping weight off. Regular weigh-ins make small regains visible before they become large ones, allowing quick adjustments to food intake, exercise, or other habits. The most useful approach is to weigh under similar conditions each time, such as in the morning before eating, so the trend is more reliable. Other habits clearly mattered, including higher protein intake, resistance training to preserve muscle, and sustainable dietary changes such as cutting back on junk food and refined carbohydrates. But beyond the medication and gadgets, the habit that appears to have anchored the entire maintenance phase was simple and repeatable: stepping on the scale every day and using that feedback to stay on course.

100 pounds came off in seven months after the ZDNET author used Mounjaro alongside an Apple Watch Ultra and a $110 Withings smart scale, then kept the weight off for six months.
Apple Watch data tracked workouts and health markers such as VO2 max, resting heart rate and lean body mass, while daily weigh-ins and trend app Happy Scale helped smooth short-term fluctuations and keep him on target.
Muscle loss was a central concern because GLP-1 users can lose up to 39% of weight from muscle; the scale's bioelectrical impedance readings suggested no lean-mass drop as he kept protein intake high and continued weights and kettlebells.
650 miles of walks, hikes and rucking this year have supported maintenance after the initial loss, and the author now plans the full 500-mile Camino Francés in 2027.
