Move More Throughout the Day
While working out is great for burning calories and building muscle, you don't want to do a morning workout and then sit at a desk all day. You want to increase NEAT, which stands for non-exercise activity thermogenesis. It's the calories you burn moving around throughout the day (not through exercise). Increasing NEAT will increase your metabolic rate, burning more daily calories, helping you lose weight.
If you sit most of the day, set reminders to stand up and walk around a few minutes every hour. Take a brisk walk during your lunch break, walk up a few flights to get to the bathroom on a different floor in your office building, or take a stroll every night after dinner.
