DIETARY INTELLIGENCE FOR MEN PAST THIRTY.

Published nutritional research suggests a range of 1.6–2.2 grams of protein per kilogram of body weight daily for men engaged in regular physical activity. Men in their 30s who prioritise lean mass maintenance typically benefit from targeting the upper end of this range, distributed across three to four meals per day.

Time-restricted eating can be compatible with regular training when nutritional intake within the eating window is sufficient to meet protein and carbohydrate requirements. For men with high training volumes, a compressed window may reduce total caloric intake in ways that impair recovery if not carefully accounted for.

Fatty fish — including mackerel, sardines, and wild salmon — represent the most bioavailable sources of EPA and DHA omega-3 fatty acids. For men following plant-based diets, algae-derived omega-3 supplements offer a documented alternative. Walnuts, flaxseed, and chia seeds contribute ALA, which the body converts to EPA and DHA at limited efficiency.

Ketogenic dietary patterns can support lean body mass when protein intake is maintained at sufficient levels — typically above 1.8 grams per kilogram — and when total caloric intake meets maintenance or slight surplus requirements. The adaptive phase of carbohydrate restriction (typically 2–6 weeks) may transiently affect high-intensity training output.

Dietary patterns influence sleep through several pathways — including the role of magnesium in nervous system regulation, the contribution of tryptophan-rich foods to serotonin and melatonin synthesis, and the impact of meal timing on circadian rhythms. Consistent meal schedules and limiting large late-evening meals are associated with improved sleep onset and quality in adult men.
