Regular Exercise increases motivation to maintain positive dietary changes.
(Castro et al., 2020)
All Strength Training, Endurance, Combination of Strength & Endurance, Unsupervised training similarly increased motivation towards maintaining positive dietary changes.
I have seen this many times with clients and myself; eating well and making better food choices when you train & diet goes out of the window when you take a break or stop training.
Exercise help build muscles, increases energy expenditure (burn calories) and makes it easier to lose weight and maintain it long-term. However, the psychological effect of making it easier to maintain positive dietary changes is a huge benefit that we don’t usually talk about.
