Pregnancy weight gain is a critical yet often overlooked aspect of maternal health, with significant implications for both mother and baby. But here's where it gets controversial: while we know excessive weight gain can lead to complications like gestational diabetes and emergency C-sections, the best ways to manage it—especially in underserved populations—remain fiercely debated. A groundbreaking study presented at ObesityWeek 2025 sheds light on this issue, revealing that a smartphone-based telehealth program for Women, Infants, and Children (WIC) recipients improved dietary habits and modestly reduced gestational weight gain. But is this enough, and for whom does it work best? Let’s dive in.
In a randomized controlled trial, pregnant women enrolled in the Healthy Beginnings program gained 1.4 kg less than those receiving standard care (P=0.04). While this difference seems small, it’s particularly notable among mothers with healthier BMIs, who saw the most significant benefits. And this is the part most people miss: even though overall weight gain differences were modest, the program led to meaningful improvements in diet quality across all groups, with participants consuming fewer calories, less sugar, and more fiber. This raises a thought-provoking question: Could focusing on diet quality be more impactful than strict weight management during pregnancy?
The Healthy Beginnings program, designed for low-income pregnant women, offered remote coaching, nutrition education, cooking classes, fitness videos, and gamified engagement. Participants received a Fitbit, a smart scale, and weekly check-ins with a coach. Yet, engagement varied: only 31% of women were highly engaged, completing over 70% of activities. This highlights a critical challenge: How do we keep underserved populations consistently engaged in telehealth programs?
Dr. Leanne Redman, lead researcher, emphasized the scalability of smartphone-based interventions, noting that WIC already uses telehealth for lactation support. “We need to better leverage telehealth, especially for hard-to-reach populations,” she said. But here’s the counterpoint: While the program reduced fat mass gain and improved diet, it didn’t significantly lower the risk of adverse outcomes like preterm births or gestational diabetes. This aligns with previous research suggesting that pre-pregnancy interventions might be more effective—a bold idea that challenges current practices.
Dr. Sharon Herring pointed out the difficulty of managing weight gain in women with obesity, a group already facing stigma. “Pregnancy might not be the ideal time to address weight concerns,” she suggested, sparking further debate. Should we shift focus to pre-pregnancy interventions, or double down on inclusive programs like Healthy Beginnings?
What do you think? Is a modest reduction in weight gain and improved diet enough to justify scaling such programs, or should we aim for more transformative solutions? Share your thoughts in the comments—let’s keep this conversation going!
