The PubMed feeds brought only papers the brief had already run, so the fitness research came from direct PubMed queries over the last 7 days. Jeff Nippard and Renaissance Periodization YouTube feeds failed again (HTTP 404). AI and finance run four items each: the rest of the window was repeats or had no use.

A pinned plugin could be swapped silently in Claude Code, Codex, Copilot and Gemini CLI

The flaw is zero click: the victim only needs a plugin from a trusted marketplace, pinned exactly as the security model says. Vendors were told in June, and two of the four still have no fix three months later.

AIR researchers disclosed Plugin4Shell on 18 September: a Git branch named after a plugin's 40 character commit hash made the agent install attacker code while reporting the reviewed, pinned version. Anthropic patched in Claude Code 2.1.179 and OpenAI in Codex 0.146.0; Microsoft has shipped no Copilot patch and Google deprecated Gemini CLI instead of fixing it.

    A consumer lawsuit says the AI slowdown pact is an illegal agreement between competitors

    Filed Friday in the Northern District of California, the suit names Anthropic, OpenAI, SpaceXAI and Google and argues that the public agreement of 12 September to slow development cuts the value of paid subscriptions. The plaintiffs say each lab may slow down on its own, but that agreeing to do it together is collusion.

    CONVOThe clean line for a finance conversation: the pact turned a safety question into a competition law question in eight days, and the complaint does not attack slowing down, only coordinating it.

    Bessent proposes a US and China notification channel for national security level AI incidents

    After talks with Vice Premier He Lifeng in New York on Sunday, the Treasury Secretary proposed an AI dialogue in which each side would notify the other of AI incidents that reach national security level. Trump and Xi are due to consider it at their Washington summit on Thursday and Friday; a similar forum discussed in Beijing in May was never formalised.

    Samsung plans to lift HBM capacity from about 180,000 to 250,000 wafers a month as China's CXMT starts mass producing new DRAM

    Sources say Samsung will double HBM4 output next year, with the HBM4 family rising from 40 to 80 percent of its high bandwidth memory production. The same weekend CXMT said its fifth generation DRAM platform is in mass production, already inside Chinese flagship phones.

The Fed and the Bank of England review bank exposure to trading firms after Jane Street's 15 billion dollar July loss

The loss did not break the firm, which still reports tens of billions of year to date trading revenue. The concern is the banks that lend to and clear for it, which S&P describes as trillions of exposure with built in fragility.

Jane Street lost about 15 billion dollars in July, its first negative trading month since 2016, largely through concentrated AI positions including its stake in Leopold Aschenbrenner's Situational Awareness fund. The Fed has opened a parallel review of how US banks manage counterparty risk to large trading firms, and the Bank of England, which warned in July about bank links to non-bank finance, is stepping up its own.

    Merz's CDU falls to 4.9 percent in Mecklenburg-Vorpommern as the AfD wins the state at 38.2 percent

    Preliminary results put the AfD on 38.2 percent ahead of the SPD on 35.4, with the chancellor's party at risk of missing the 5 percent threshold, its worst result since 1949. Die Linke won Berlin, where the AfD came third on 16.1 percent; Merz called it a disaster and says he stays and presses on with reforms.

    Chinese biotech stocks jump on a report that the US will keep allowing most drug licensing deals with Chinese firms

    The Hang Seng Biotech index rose more than 5 percent, with Akeso and Sino Biopharmaceutical up 8 percent, after Reuters reported the Treasury is drafting rules that would exclude only pathogen and weaponisable biotech. Almost half of US drug in-licensing deals in 2025 were with Chinese firms, and 81 out-licensing deals worth 110 billion dollars closed in the first half of 2026.

Last 7 daysThe week's new research kept finding that the label on a diet explains less than the calories inside it. Ultra-processed food raised intake only where it was also more energy dense, three different diets on the same calorie prescription lost the same 8.47 kg, and video consultations matched in person care on weight. What differed was adherence and continuity, not the method name.
This quarterFor ninety days the quarter bucket graded add-ons and found small effects: whole body vibration and blood flow restriction on 29 June, creatine on 6 July, photobiomodulation on 20 July, keto at matched energy on 13 August, HMB on 5 September, ashwagandha on 15 September. On 18 September the MRI study opened the first intake question about food quality rather than dose, with calories accounted for. Today's trial level meta-analysis pulls that thread back towards energy: in randomised trials the ultra-processed effect on intake disappears when energy density is matched, which extends the 13 August keto result, where the gap vanished once the comparison was fair.

Across 10 randomised trials, ultra-processed diets raised intake only when they were also more energy dense

Diets in the trials were never matched on nutrient profile, so the review cannot say processing itself does anything. The one large effect that survived was eating rate, which is a behaviour, not an ingredient.

A pre-registered meta-analysis from Liverpool found greater weight gain (SMD 0.65) and faster eating (SMD 0.96) on ultra-processed diets, while the effect on energy intake varied by model (SMD 0.18 to 0.44). When the ultra-processed diet was more energy dense the intake effect was 0.71; when energy density was similar it was 0.02, and certainty was rated low.

Critical Reviews in Food Science and Nutrition

sharpensprotein-satietyThe intake gap followed energy density (0.71 versus 0.02), not the processing label; appetite ratings and palatability did not differ.

SHINOMEKeep the client explanation on calories per bite, not on the processing label: this is the trial evidence behind the money metaphor in the nutrition guide rebuild, and it lets you answer the ultra-processed question without a food judgment.

    Three calorie-restricted diets lost the same 8.47 kg in 12 weeks, and the one people followed best lost less lean mass

    In 102 Chinese men with overweight and high uric acid, a carbohydrate-restricted diet, DASH and a low purine diet were all prescribed 20 to 25 kcal per kg of ideal body weight; weight loss was identical across arms (P = 0.99) and 83 percent completed. Adherence was higher on DASH, which also showed less soft lean mass loss than the carbohydrate-restricted arm.

    Diabetes Care

    supportsenergy-balanceMatched calorie prescriptions produced identical weight loss across three diet patterns; adherence, not the pattern, separated them.

    SHINOMEUse it in the intake call when a client asks which diet: same calorie prescription, same weight loss, and the difference showed up in which plan people could keep following.

    Video consultations matched in person obesity care on weight over 12 months, and every missed video visit was made up

    In a 32 person pilot RCT in a Sao Paulo public clinic, weight changed by minus 4.8 percent with telehealth and minus 5.5 percent in person, and 56 versus 63 percent reached 5 percent loss. Missed appointments were similar (12.5 versus 17.1 percent), but all 10 missed telehealth visits were rescheduled and attended against 8 of 14 in person (P = 0.024).

    Adding a time-restricted eating window to exercise cut 1.64 kg more than a control diet with exercise, and left fat-free mass alone

    Eleven RCTs with 602 adults with overweight or obesity: against a control diet plus exercise, time-restricted eating plus exercise reduced weight by 1.64 kg, fat mass by 1.30 kg and waist by 1.53 cm, with no significant effect on fat-free mass, glucose, lipids or blood pressure. The abstract does not state whether calorie intake was matched between arms.

    Nutrition Reviews

    sharpenstwo-mealsA shorter eating window with training lost 1.3 kg more fat without lean mass cost; intake matching is not reported, so timing and calories stay tangled.

    SHINOMERead this as a modest effect you cannot yet split between the window and the calories it removes; that is the honest answer when a client asks whether two meals beat three.

    In women who train, creatine shows small effects on performance and lean mass, at low to very low certainty

    A multilevel meta-analysis of 21 studies and 424 analysable female participants found g = 0.30 for performance and 0.24 for body composition, with the overall estimate at 0.23. The body composition outcomes did not point in a uniform direction, and physiological outcomes were uncertain (g = 0.10).

    Frontiers in Nutrition

    sharpensmuscle-is-capitalA small lean mass related effect (g = 0.24) at low certainty; another add-on smaller than the training it sits on.

    SHINOMEHave this ready for the women on the roster who ask about creatine: the measured effect is small and the certainty is low, so it sits well behind training and protein in the order of priorities.

    Walking with blood flow restriction cuffs beat plain walking on fitness, strength and function across 12 trials

    Compared with the same walking without cuffs, BFR walking improved cardiovascular fitness (g = 0.31), lower limb strength (0.32), muscle size (0.26) and functional performance (0.57). Study quality was rated low to very low with a high risk of bias, and intensity and volume did not change the result.

    Journal of Sports Sciences

    sharpenswalk-firstWalking can carry a strength signal when cuffs are added, at low certainty; it does not change the case for plain walking as the first habit.

    SHINOMEFile it as a later option for clients who cannot load their legs yet, not as a walking upgrade for everyone: the effects are small to moderate and the trials are weak.
