   Mixed training beat walking on waist size

   In a randomised trial of 57 adults aged 45-60 with type 2 diabetes-associated dyslipidaemia and BMI above 25, a 12-week programme combining aerobic, resistance and flexibility exercise significantly reduced BMI, waist circumference and waist-to-hip ratio and improved quality-of-life scores, with greater benefits than a control group that continued routine activity and walking.

   ⚠What it shows: One single-centre randomised trial, 57 adults aged 45-60 with type 2 diabetes and dyslipidaemia, 12 weeks only; the abstract reports body composition and self-reported quality of life but no blood lipid or glucose outcomes, and the control group simply carried on walking.Study · Cureus

   Yoga and meditation shifted PCOS weight and androgens

   Pooling 10 randomised trials in women with polycystic ovary syndrome, mindfulness-based practices such as yoga and meditation were associated with reductions in BMI, body weight and abdominal circumference, alongside lower total testosterone and less clinical hirsutism. Generic depression and anxiety scores did not shift significantly, but disease-specific quality of life did.

   ⚠What it shows: Meta-analysis of 10 small RCTs totalling just 356 women with PCOS; the insulin-resistance signal rests on only two studies, interventions and measurement varied, and pooled effects from small trials often shrink on replication.Meta-analysis · Appl Psychol Health Well Being

   Global metabolic syndrome hits up to a third of adults

   Pooling 684 observational studies covering 44,979,527 adults, global metabolic syndrome prevalence was estimated at between 19% and 31%, with the highest figures reported in South Asia and in Latin America and the Caribbean. Prevalence did not differ significantly between pre-pandemic and post-pandemic studies.

   ⚠What it shows: Proportional meta-analysis of 684 observational studies reporting crude prevalence; heterogeneity was substantial, metabolic syndrome definitions and sampling differ between studies, and the socioeconomic correlates come from meta-regression, so they are ecological associations rather than causes.Study · Eur J Cardiovasc Nurs

   Semaglutide's weight edge comes with a gut-trouble bill

   Pooling four randomised trials in 3613 adults with overweight or obesity but no type 2 diabetes, subcutaneous semaglutide produced 11.85% more weight loss than placebo, while gut side effects and dropouts from side effects were markedly more common.

   ⚠What it shows: Meta-analysis of only four randomised trials totalling 3613 non-diabetic adults with overweight or obesity; trials were relatively short, so durability of weight loss and long-term safety remain untested, and side effects drove significantly more discontinuation.Meta-analysis · Medicine (Baltimore)

   Cardio plus weights topped the list for HbA1c

   Pooling 34 randomised trials in 2461 adults aged 60 and over with type 2 diabetes, every exercise type beat control for HbA1c, but combined aerobic plus resistance training led the field with a 1.05% reduction and ranked first across glycaemic outcomes. Benefits on HbA1c appeared to start at roughly 520 MET-min per week.

   ⚠What it shows: Systematic review and Bayesian network meta-analysis of 34 RCTs (2461 participants, mean age 60+); modality rankings rest on indirect comparisons, the 2-hour glucose evidence was sparse, and the dose-response curves need confirmation in purpose-built trials.Meta-analysis · Front Endocrinol (Lausanne)

   Lifting twice a week tracked with better cholesterol ratio

   In up to 4,881 British adults aged 46-48, lifting weights at least twice a week was associated with a 3.99% lower total-to-HDL cholesterol ratio even after adjusting for device-measured moderate-to-vigorous activity and other lifestyle factors. Associations with blood pressure and HbA1c faded once smoking, alcohol, education, self-rated health and disability were accounted for.

   ⚠What it shows: Cross-sectional analysis of one birth cohort (up to 4,881 adults aged 46-48); resistance exercise frequency was self-reported, so no causal direction can be established and only one of three outcomes survived full adjustment.Study · Sport Sci Health

   Low activity tracked with sharply higher diabetes odds

   Among 863 adults in routine primary care, type 2 diabetes prevalence fell in steps across activity levels, from 29.7% in the least active to 8.9% in the most active. After adjustment, low activity was associated with 4.32 times the odds of documented type 2 diabetes compared with high activity, and moderate activity with 2.07 times the odds.

   ⚠What it shows: Cross-sectional observational study of 863 primary-care patients with activity estimated in routine physician interviews; no HbA1c, glucose, diet or medication data, so cause and direction cannot be established.Cohort · Medicina (Kaunas)

   Esports and health: not worse overall, but more body fat

   Pooling 53 studies covering 86,652 people, esports players did not differ from non-players on physical activity, BMI, sleep duration, anxiety, stress or grip strength, and showed slightly lower depression scores after sensitivity analysis. Non-professional players did carry 4.57 percentage points more body fat, and participation correlated with sedentary behaviour, BMI and gaming disorder.

   ⚠What it shows: Systematic review and meta-analysis of 53 studies (86,652 people), but the included studies were cross-sectional with moderate risk of bias and high heterogeneity, so nothing here shows direction of cause.Systematic review · Sports Med Open

   Mixed training beat cardio alone on teen insulin markers

   In a pooled analysis of 12 randomised trials, combining aerobic and resistance training in overweight or obese adolescents lowered fasting insulin and blood pressure versus no exercise, and modestly beat aerobic exercise alone on fasting insulin, HOMA-IR and adiponectin. Fasting glucose, total cholesterol and triglycerides did not budge.

   ⚠What it shows: Meta-analysis of only 12 RCTs in overweight or obese adolescents; GRADE rated most outcomes low or very low quality, protocols varied widely, blinding was absent and studies clustered regionally, so effect sizes should be read cautiously.Review · Front Public Health

    Time-restricted eating lowered fasting glucose, not HbA1c

    In 10 randomised trials with 599 adults with prediabetes or type 2 diabetes, time-restricted eating windows of 4-10 hours lowered fasting blood glucose by 0.30 mmol/l and body weight by 1.6 kg, but produced no significant overall change in HbA1c. HbA1c did fall modestly in the prediabetes subgroup only.

    ⚠What it shows: Meta-analysis of 10 RCTs totalling 599 adults, mean study length 4 months, graded moderate certainty; confidence intervals in several included trials were wide because samples were small, and effects on insulin sensitivity, beta cell function and continuous glucose monitoring were inconclusive.Systematic review · Diabetologia

    Strong grip linked to 44% lower diabetes risk

    In 141,848 UK Biobank adults, those in the highest third for grip strength relative to fat-free mass had a 44% lower hazard of developing type 2 diabetes over a median 7.4 years, after adjusting for genetic risk. The protective association was weaker, but still present, in those at highest genetic susceptibility.

    ⚠What it shows: Large prospective observational cohort (141,848 white British adults, 4,743 diabetes cases, median 7.4 years): associations only, not proof that building strength prevents diabetes, and results may not generalise to other ancestries.Study · BMC Med

    Each 10% more time in range tracks lower mortality

    Pooling 24 observational studies and 35,916 people with type 2 diabetes, each 10% more time spent in the target glucose range was associated with lower all-cause mortality and lower risk of retinopathy, lower-limb atherosclerotic disease and peripheral and autonomic neuropathy. Associations for albuminuria and amputation did not reach significance.

    ⚠What it shows: Meta-analysis of 24 observational studies, so these are associations and cannot prove that raising time in range causes the lower risk; monitoring methods varied from continuous sensors to fingertip testing, and albuminuria and amputation outcomes were null.Review · J Clin Med

    Fasting vs calorie cutting: less magic than you think

    In adults with prediabetes or type 2 diabetes, intermittent fasting cut body weight by 4.56 kg and lowered HbA1c, fasting glucose, cholesterol and triglycerides versus control diets, but against straightforward calorie restriction it added only modest extra weight loss and no metabolic advantage.

    ⚠What it shows: Meta-analysis of 14 randomised trials (1,101 adults with prediabetes or type 2 diabetes); fat mass, insulin, LDL, HDL and blood pressure did not improve versus control, and versus calorie restriction there were no differences in glycaemic markers, lipids or blood pressure.Meta-analysis · Diabetes Obes Metab

    Health apps move blood pressure and glucose, not mortality

    An umbrella review of 78 meta-analyses covering 177 373 participants found app-based interventions improved blood pressure, HbA1c, fasting and post-meal glucose, bodyweight, waist circumference, physical activity, diet quality, mood and medication adherence versus controls. There was no significant effect on cardiovascular mortality, cholesterol or triglycerides, body fat, hospitalisation or smoking abstinence.

    ⚠What it shows: An umbrella review of existing reviews, so quality is inherited: only 1% of the 78 included reviews was rated high quality and 73% critically low, heterogeneity was very high for most outcomes, and several authors are employed by a food company.Study · Lancet Digit Health
