Recent Developments

Sep 8, 2025 - WeightWatchers Exits Bankruptcy, Adds Women’s Health Program
  • WeightWatchers exited Chapter 11 bankruptcy in June 2025, reducing its debt load by $1.15 billion, the company announced. WeightWatchers has struggled in recent years to adapt its business model to the fast-changing weight loss industry, which has been upended by weight-loss drugs like Ozempic. While the company has added a clinical component incorporating weight-loss drugs, the growth has not been fast enough to offset a decline in subscriptions to its core programs. CEO Tara Comote said the company expects to accelerate its transformation following the bankruptcy. It is adding a new program aimed at supporting women through perimenopause, menopause, and post menopause with clinical care, nutritional strategies, and coaching. Per Comote, “Our integrated model, spanning clinical care, behavioral support, and community, puts us in a powerful position to reinforce our leadership in long-term weight health.”
  • Indicators measuring the collective mood of US consumers show mixed signals, with consumer confidence levels slightly up and consumer sentiment falling. Consumer confidence levels, an indicator of discretionary expenditures, improved in July 2025, month over month, rising by 2 points, according to the Consumer Confidence Index. Consumer confidence levels have stabilized since May but remain lower than last year’s, according to The Conference Board, which publishes the monthly index. July’s gain can be attributed to consumers over 35 years old and shared across all income groups, except the lowest income group earning below $15K. In addition, the consumer sentiment index from the University of Michigan dropped in August 2025 for the first time in four months. The index fell to 58.6 in preliminary August data from 61.7 in July. Year-ahead inflation expectation results were higher monthly, as consumers convey lingering anxiety about prices amid tariff impacts. The index serves as a predictor of consumer spending as it indicates consumers’ perception of their financial prospects and the broader economy.
  • According to a recently released report by the National Center for Health Statistics in Deseret News, the average weight for US adults and teens has tipped the scale into the obesity range. The study analyzed the body composition of thousands of Americans between August 2021 and August 2023. The average adult male 20 and older was slightly under 5-foot-9 and weighed 199 pounds, with a resulting body mass index of 29.4, which is considered overweight. For women, the average adult female was 5-foot-31/2 and weighed 171.8 pounds, which provided a BMI of 30, considered obese. A BMI of between 18.5 and 24.9 is considered in the normal range for adults, 25 to 29.9 is overweight, and over 30 is obese. The report showed that the share of children who have obesity increases with age, with children tipping into the overweight category as they reach adulthood.
  • Reflecting the challenges facing the industry, sales for the US diet and weight reducing centers industry are projected to grow at a CAGR of 1.9% between 2025 and 2029, according to a forecast from Inforum and the Interindustry Economic Research Fund, Inc. The expected growth rate is slower than the overall economy‘s anticipated growth. Diet and weight reducing services are part of the “other services” sector, which is driven by consumer spending, along with expenditure by businesses. Consumer sentiment is likely to improve in the forecast period, which bodes well for the sector. Factors that may limit consumer spending are higher tariffs on consumer goods, which may be painful for households. On a positive note, lower inflation supports a moderate increase of real disposable income by about 2% in 2025 and 1.9% in 2026. Real income could suffer to an extent if average prices rise due to tariff implementation.
