The Claim

Resistance exercise and high-protein diet do not interact synergistically to enhance metabolic flexibility in healthy older men, as no significant differences were observed in npRQ transitions between combined intervention and resistance exercise alone.

Source: Metabolic flexibility following resistance exercise and a high protein diet in older men: Results from a 12-week randomized controlled trial.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

In healthy older men, combining resistance exercise with a high-protein diet does not produce a greater improvement in metabolic flexibility than resistance exercise alone, based on measurements of npRQ transitions.

See the scientific wording

Resistance exercise and high-protein diet do not interact synergistically to enhance metabolic flexibility in healthy older men, as no significant differences were observed between those receiving both interventions versus resistance exercise alone across all measured npRQ transitions.

Why this might work

Lifting weights increases the number of glucose transporters in muscle cells and improves the efficiency of energy-producing structures inside the cells, allowing the body to switch more effectively between burning fat and sugar for energy.

1 study
  1. Study: Metabolic flexibility following resistance exercise and a high protein diet in older men: Results from a 12-week randomized controlled trial.

    The study found that lifting weights improved how well older men’s bodies switch between burning fat and sugar, but adding extra protein didn’t make it any better than weights alone.
