Post-pandemic weight loss: There’s an app for that

 With obesity rates continuing to rise in the United States, and with more than 40% of Americans reporting undesired weight gain since the start of the COVID-19 pandemic, many people are seeking tools to help them shed the extra pounds. While the focus on dieting and weight loss has historically been on what and how much to eat, many companies are now turning their attention to the why and how of our eating behaviors: they are taking a more nuanced approach to help people understand why they eat the way they do, and how to make improvements in their eating routine.


A search for "weight loss" in any web browser or app store reveals hundreds of apps and programs designed to help people lose weight. While by no means a comprehensive review, the following weight-loss apps and programs are notable for some of the nuances in the features and program options they offer:


Noom uses artificial intelligence, cognitive behavioral therapy, and evidence-based principles of physiology and psychology to help people improve their eating behaviors with the assistance of support groups, daily educational activities, and interactive psychology-based challenges.

myWW+ (an app from WW, formerly Weight Watchers) uses their SmartPoints system — a numeric value assigned to every food item based on calorie, protein, sugar, and fat content — in combination with a flexible color-coded range of food plans. Each member is assigned to a plan after taking a personal assessment, and all plans have a personalized SmartPoints budget and list ZeroPoint food options. The MyWW+ app features 24/7 access to a health coach, guided workouts, meditations, and a sleep tracker.

Eat Right Now combines mindfulness training with an evidence-based, guided approach to help users rewire their brains to identify emotional triggers, recognize cravings, stop negative habits, and develop emotional resilience to help stop binge and emotional eating.

Reset offers a particular variation of the popular intermittent fasting protocol where users track food intake and follow a strict eating plan for only two "reset" days out of the week, and receive guidance and 1:1 coaching to help them sustain long-term healthy habits.

Livongo is an employer-based virtual telemedicine and health coaching service that provides patients with chronic disease management through consultation with health coaches who provide dietary and lifestyle advice, as well as medical providers who prescribe appetite-suppressing medications to those who qualify. They provide smart Bluetooth-connected scales and other medical devices for monitoring and transmitting health data.

What's the evidence that these tools work for sustained weight loss?

A 2016 study of data analyzed from nearly 36,000 Noom users determined that 77.9% of participants reported a decrease in body weight while using the app, and 22.7% of users experienced greater than a 10% body weight reduction compared to their baseline weight.

HIV rates rising: Could new forms of PrEP help?

 In 2021, HIV continues to be a disease with huge national and international impact. There are over 1.2 million people in the US estimated to be living with HIV today, and approximately 1.7 million new infections occurred globally last year. In parts of the US, HIV rates are currently climbing among underserved populations. We’ve seen a recent epidemic among people without stable housing in Boston, and similar outbreaks in areas like West Virginia and Philadelphia. The COVID-19 pandemic has only exacerbated the problem because many people have had less access to testing and medical care for HIV. Now more than ever, medicines known as pre-exposure prophylaxis — or PrEP — could help reverse this worrisome trend by preventing people from getting HIV. And new formulations could make it easy for a much broader range of people at risk for HIV to use PrEP. Already, one is being reviewed by the FDA. What is PrEP, and is it an option for me? PrEP is a combination of medicines that significa...

WERE YOU NOTIFIED ABOUT MISSING TAX FORMS FOR YOUR ACA SUBSIDY? BLAME COVID.

When they file their annual taxes they complete an IRS form that reconciles how much they received in advance tax credits against their actual income for the year. The letter from the marketplace said they hadn’t filed for 2019, but Schenker knew they had — just as they have every year. “I was more annoyed than anything else,” Schenker, 55, said, remembering an earlier enrollment problem that took months to resolve. “I didn’t want to get stuck in some sort of appeals category.” Schenker’s 25-year-old daughter, Kaily Schenker, who is part owner of the family’s organic farm, got the same letter about her plan. Schenker helps her with her taxes, and she also filed the Form 8962 paperwork, he said. Officials at the Centers for Medicare & Medicaid Services, which oversees the ACA marketplaces, confirmed that some consumers received notices from the agency alerting them that, according to the IRS, they hadn’t filed a tax return or reconciled their advance payments for tax credit...

Healthy Habits May Help You Live More Than 10 Years Longer

New research published by the American Heart Association (AHA) suggests that adults in the US who follow 5 healthy lifestyle habits may live more than a decade longer compared with people who follow none of the 5 habits. These 5 habits are: eating a healthy diet getting regular exercise not smoking staying at a healthy weight limiting alcohol Starting at age 50, men in the study were estimated to have an average life expectancy of 14 years and women were estimated to have an average life expectancy of 12 years when they followed all 5 habits. The study was published April 30, 2018 in the AHA journal Circulation. The study authors point out that the US ranks 31st in the world for life expectancy among those born in 2015, even though it’s one of the richest countries in the world and spends more on health care per person as a percent of gross domestic product than any other country. According to the authors, the US healthcare system focuses mainly on drug discovery and disease management...
