    I’m excited to announce my new book FOOD INTELLIGENCE coauthored with brilliant journalist @juliaoftoronto! Cutting through the confusion about diet & health, #FoodIntelligence describes the fascinating science of how food both nourishes and harms us. penguinrandomhouse.com/books/671334/f…

    After 21 years at my dream job, I’m very sad to announce my early retirement from the National Institutes of Health. My life’s work has been to scientifically study how our food environment affects what we eat, and how what we eat affects our physiology. Lately, I’ve focused on

    Just submitted our latest manuscript entitled "A plant-based, low-fat diet decreases ad libitum energy intake compared to an animal-based, ketogenic diet: An inpatient randomized controlled trial". I'm looking forward to all constructive comments! osf.io/preprints/nutr…

    I was honored to lead an international team of renowned obesity scientists (including @Farooqi_Lab @StephenORahilly @DrLeanneRedman @JohnSpeakman4 @deirdre_tobias) to address widespread misunderstandings about modern obesity science in @AJCNutrition: academic.oup.com/ajcn/advance-a…

    Our latest RCT paper was just submitted for peer review and now available as a @NutriXiv preprint: "Ultra-processed diets cause excess calorie intake and weight gain: A one-month inpatient randomized controlled trial of ad libitum food intake". osf.io/preprints/nutr… 1/7

    Debates about diet mechanisms and physiology can be tiresome and confusing. It's sometimes lost that there's a lot of common ground regarding diet: To the extent possible, avoid ultra-processed foods and make an abundance of non-starchy vegetables the foundation of your diet.

    Very sad to hear this from you @calleymeans given the many times I’ve reached out to start a discussion with you. It’s not too late! I would be happy to return to serve the American people and do the gold-standard, unbiased science to unravel the root causes of diet-related

    A paper by @AdrianSotoMota @nicknorwitz @davidludwigmd et al. reanalyzed data from our previous study, claiming to have invalidated our primary findings, & concluding that our data support the carbohydrate-insulin model (CIM) of obesity. Our response:

    Answers to a few questions from @bigfatsurprise about incidences of censorship I recently experienced at NIH: 1. My request was denied by HHS to present an invited keynote talk on my ultra-processed food (UPF) research at the Bloomberg Philanthropies annual Food Policy Program

    Hi @KevinH_PhD, I wrote you privately earlier today and am now asking publicly: I'm wondering if you have released or could release any of the following: --the name of the conference to which you said you'd been invited but that the NIH would not allow you to attend --the name

    There's widespread misunderstanding of the energy balance model (EBM) of obesity. The EBM does NOT postulate that food intake is primarily under conscious control or that obesity is a failure of willpower and can be effectively treated by calorie counting or advice to “eat less”.

    Policies that discourage consumption of ultra-processed foods should be sensitive to the time, skill, expense, and effort required to prepare meals from minimally processed foods—resources often in short supply for those who are not members of the upper socioeconomic classes.

    BBC News ‘Ultra-processed foods have hijacked our appetites and we need to shift back to real food’ Let’s once again also bust the myth of physical inactivity and #obesity. You can’t out cycle a bad diet prime minister! m.youtube.com/watch?v=55CrH0…
