“intermittent fasting could be part of a healthy lifestyle.”

Mark Mattson, PhD — Johns Hopkins Medicine · 2019 ↗On intermittent fasting research

“People love intermittent fasting because it’s easy. People need to find diets that they can stick to long term.”

Krista Varady, PhD — UIC Today · 2021 ↗On sustainable habits

“In time-restricted eating, we are re-engaging the body’s natural wisdom and harnessing its daily rhythms to restore metabolism and improve health.”

Satchidananda Panda, PhD — Salk Institute · TIMET trial, 2024 ↗On a trial in adults with metabolic syndrome

“That’s the power of understanding the fundamental ability of organisms to repair themselves.”

Valter Longo, PhD — USC · Vitality magazine, 2019 ↗On fasting-mimicking diet research

“The best diet for any given person is the one that they can adhere to.”

Vicki Catenacci, MD — NIH News in Health · 2019 ↗On finding a sustainable approach

“We’ve shown that time-restricted eating is a feasible way for shift workers, such as firefighters, to improve their cardiovascular health and wellbeing.”

Pam Taub, MD — Salk Institute · 2022 ↗On a 10-hour eating-window trial in firefighters

“It absolutely depends on your schedule for how easy this would be to adopt.”

Emily Manoogian, PhD — Where Cures Begin · Salk podcast, 2019 ↗On fitting time-restricted eating into daily life

“Eating at the right time of the day, when your metabolism is naturally higher, may improve your health.”

Courtney Peterson, PhD — UAB News · 2021 ↗On studying meal timing and circadian rhythms

“Time-restricted eating is a simple dietary intervention to incorporate, and we found that participants were able to keep the eating schedule.”

Satchidananda Panda, PhD — UC San Diego Health · 2019 ↗On a pilot study in adults with metabolic syndrome

“This study adds to the growing body of evidence showing the importance of how you eat.”

Kate Bermingham, PhD — King’s College London · 2023 ↗On self-reported experiences in a meal-timing study

“This could give people who are trying to lose weight more options.”

Maggie Stanislawski, PhD — CU Anschutz · 2023 ↗On comparing intermittent fasting and daily calorie restriction

“Beyond just using fat there’s a lot that goes on in the body and brain when this metabolic switch occurs.”

Mark Mattson, PhD — Johns Hopkins Medicine · Podcast, 2020 ↗On the biology of fasting

“A lot of people like time-restrictive eating because it’s a simple rule to follow…”

Alexis Supan, RD — Cleveland Clinic · 2024 ↗On simplicity alongside a balanced diet

“When it comes to weight loss, people need to find what works for them.”

Krista Varady, PhD — UIC Today · 2017 ↗On choosing between dietary approaches

“If these findings hold true in people, we might want to rethink whether we really want that midnight snack.”

Joseph Takahashi, PhD — UT Southwestern · 2022 ↗On meal-timing research in mice; human effects unconfirmed

“One hypothesis is that fasting can activate cellular mechanisms that help boost immune function and reduce inflammation associated with chronic disease.”

Frank Hu, MD, PhD — Harvard Health · 2019 ↗On a proposed mechanism, not a proven treatment

“We found that there is a system-wide, molecular impact of time-restricted eating in mice.”

Satchidananda Panda, PhD — Salk Institute · 2023 ↗On gene-expression research in mice

“The more important message to me is that this is a dietary strategy that is an evidence-based alternative…”

Victoria Catenacci, MD — CU Anschutz · 2025 ↗On a 4:3 modified-fasting trial with behavioral support

“The longevity diet is not a dietary restriction intended to only cause weight loss but a lifestyle focused on slowing aging…”

Valter Longo, PhD — USC · 2022 ↗On a proposed dietary framework and research agenda

“We really do need long-term data to see if people can do intermittent fasting for the long term.”

Krista Varady, PhD — UIC Today · 2022 ↗On the next questions for fasting research

“intermittent fasting could be part of a healthy lifestyle.”

Mark Mattson, PhD — Johns Hopkins Medicine · 2019 ↗On intermittent fasting research
