Recent Developments

Jul 7, 2025 - Higher Percentage of US Adults Are Obese: Report
  • 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.
  • Consumer sentiment, an indicator of discretionary spending, was mixed in June 2025, according to two major indicators. The final index of consumer sentiment from the University of Michigan grew 15.9% in June 2025 from the previous month, as the Trump administration put some tariffs on hold against major US trade partners, according to CFO Dive. Year over year, the index of consumer sentiment was down 11.3%. An index measuring consumers’ expectations for the future was up 21.9% from the previous month, but was down 16.1% year over year. According to survey director Joanne Hsu, “Consumers appear to have settled somewhat from the shock of the extremely high tariffs announced in April and the policy volatility seen in the weeks that followed.” Hsu noted that consumers’ views of business conditions, personal finances, buying conditions for big ticket items, labor markets and stock markets all remain below six months ago. However, the Consumer Confidence Index fell by 12.3 points in June 2025, compared to the previous month. The index dropped in June following a gain in May, according to The Conference Board, which publishes the monthly index.
  • 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.
  • According to the Wall Street Journal, WeightWatchers filed for Chapter 11 bankruptcy in May 2025, seeking to reduce its debt load by $1 billion. 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 that deleveraging will free up cash flow to help it compete and innovate.
