Ultra-processed foods just got harder to defend: a dose-response meta-analysis of 8.8 million adults found risk climbing for seven chronic diseases with every extra 100 grams a day. Plus: gut bacteria may predict who keeps weight off after fasting, and a factorial trial found protein targets didn’t move the needle on muscle gains when training stayed constant.

Evidence Spotlight
|
Ultra-Processed Food Risk
Ultra-processed food (UPF) intake tracks with a higher risk across a broad range of chronic diseases, according to a dose-response meta-analysis of 51 prospective cohort studies pooling 8.8 million adults. Digestive disease and depression/anxiety showed the largest jumps in risk, at 31% and 27% higher respectively, while all-cause mortality risk was 18% higher.
The dose-response gradient strengthens the case for a real effect: each additional 100 grams of ultra-processed food eaten daily raised cardiovascular event risk by 14% and all-cause mortality risk by 3%. Because the underlying data are observational cohort studies rather than randomized trials, the authors rate overall certainty of evidence as low to moderate.
Takeaway: This adds weight to treating ultra-processed food reduction as a broad chronic-disease prevention lever, not just a weight-management tool. The observational design supports conversations about dietary pattern, but it can’t establish that cutting ultra-processed foods alone causes the risk reduction.

Protein Targets & Muscle Mass
Assigned protein targets made no measurable difference in skeletal muscle mass gains among middle-aged and older women doing supervised resistance training. This 12-week randomized factorial trial (n=108, ages 40-77) tested three protein doses — 0.8, 1.6, and 2.2 grams per kilogram of body weight daily — layered onto either resistance training (RT) alone or RT plus cycling (concurrent training).
Resistance training alone produced greater leg-press strength gains than the combined protocol, while the combined protocol produced better estimated cardiorespiratory fitness and lower body-fat percentage — but neither difference tracked with protein dose. The complete-case analysis included 83 of the 108 women randomized, and a null finding on one 12-week trial doesn’t prove all protein doses work equally well over the longer term.
Takeaway: This suggests that for women already doing structured resistance training in this age range, hitting a specific protein target may matter less than the training stimulus itself — though the trial doesn’t rule out longer-term or additive effects at higher training volumes.

Fasting & Microbiome Prediction
A small but notable randomized trial (n=38) found that baseline gut microbiome and lab markers can help predict which healthy adults sustain weight loss after a 5-day prolonged fast. Participants who lost the most body fat at 12 weeks tended to share specific baseline features: certain Faecalibacterium and Oscillibacter species, along with lower LDL cholesterol and systolic blood pressure.
The prediction model, built with machine learning, held up when tested in three independent cohorts fasting for different lengths of time, including people with metabolic syndrome and multiple sclerosis. Fasting itself reshaped the gut microbiome and metabolite profile in the original 38 participants, though the small primary sample means these predictors need confirmation in larger trials before wider use.
Takeaway: This is early evidence that who benefits most from prolonged fasting may be identifiable in advance from gut microbiome and basic labs — worth watching as personalized fasting protocols develop, but not yet ready to guide who should or shouldn’t try fasting.

By The Numbers
Just 100 grams
a day was enough to raise chronic disease risk, in a dose-response study of 8.8 million adults.
This meta-analysis of 51 cohort studies found that every additional 100 grams of ultra-processed food eaten daily — a small, easy-to-miss increase — raised cardiovascular event risk by 14% and all-cause mortality risk by 3%, with even bigger jumps for digestive disease (31% higher) and depression/anxiety (27% higher).

Clinical Pearl
Protein targets didn’t build extra muscle
In a 12-week factorial trial of 108 women aged 40 to 77, assigned protein targets of 0.8, 1.6, or 2.2 grams per kilogram of body weight daily made no measurable difference in skeletal muscle mass, whether paired with resistance training alone or resistance training plus cycling. The training stimulus — not the protein dose — appeared to drive the muscle response.

Tech Tip

Let AI Sign In for You Without Ever Seeing Your Password
Never paste a password into an AI chat, because it becomes part of the conversation. A new beta, 1Password for Claude, handles browser logins differently. When Claude hits a sign-in page, it asks 1Password for the login. A prompt shows exactly which login it wants, and nothing is filled in until someone approves with a fingerprint or face scan.
According to Anthropic, the password and any one-time code never enter Claude’s context, memory, or Anthropic’s systems. The fine print: paid Claude plans only, and it needs the Claude desktop app on a Mac plus Claude in Chrome. Team or Enterprise admins must turn it on.
Do this: use it for low-stakes sites like webinar platforms or supplier portals, and keep EHR, banking, and patient portals out of AI browsing altogether.
