Combining regular physical activity with targeted nutrition—such as vitamin D, omega-3s, or protein—may work better together than either alone to improve muscle and brain health in people with obesity and type 2 diabetes.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether combining exercise with specific nutritional interventions produces greater improvements in myokine levels and functional outcomes than either intervention alone in metabolic disease.
A systematic review and meta-analysis of at least 15 randomized controlled trials comparing exercise alone, nutrition alone, combined exercise+nutrition, and control in adults with obesity or type 2 diabetes, with pooled effect sizes for irisin, BDNF, muscle mass, and cognitive performance.
Whether combining aerobic exercise with vitamin D and omega-3 supplementation produces greater increases in irisin and cognitive function than either component alone.
A 2×2 factorial RCT of 200 adults with type 2 diabetes randomized to: (1) placebo + no exercise, (2) placebo + aerobic exercise (150 min/week), (3) vitamin D (2000 IU/day) + omega-3 (3000 mg/day) + no exercise, or (4) exercise + supplements, measuring serum irisin, BDNF, MoCA, and lean mass at baseline and 16 weeks.
Whether individuals who combine regular exercise with specific dietary patterns show higher myokine levels and slower functional decline than those using only one strategy.
A prospective cohort study of 500 adults with type 2 diabetes followed for 4 years, with annual assessment of physical activity, dietary intake (omega-3, vitamin D, protein), serum myokines, muscle strength, and cognitive performance, adjusting for confounders.
The association between combined exercise and nutritional behaviors and circulating myokine levels in a population with metabolic disease.
A cross-sectional analysis of 300 adults with type 2 diabetes, categorizing participants by exercise status (yes/no) and nutritional intake (high/low omega-3, vitamin D), and comparing serum irisin and BDNF levels across groups.
Whether individuals who combine exercise and targeted nutrition exhibit exceptional myokine responses and functional outcomes.
A case series of 5 individuals with type 2 diabetes who combined daily aerobic exercise with vitamin D (5000 IU/day) and omega-3 (4000 mg/day) for 6 months and exhibited >60% increases in irisin and BDNF alongside >15% gains in muscle strength and cognitive scores.
