If you're not up for crunching numbers every day, you can take a more generalized approach. “For some people, it’s knowing, ‘Typically I eat a whole sandwich,’” says Gagliardi. “Now, I’m going to eat half a sandwich at lunch and save the other half for my dinner and cut my calories in half." To get started, consider these 25 ways to cut 500 calories a day.
Break up your workouts. Your metabolism spikes after every bout of physical activity. So if you can break up your hour workout into two half-hour chunks, you'll get two spikes instead of one. Your body burns calories at a higher-rate after a workout (sometimes for several hours after), and if you rejuvenate it later in the day, you'll further enhance the effect.
2. Eat smaller meals more frequently: “Insulin is probably the single most important factor that contributes to fat storage,” Seedman explains. This hormone is activated when you eat and responsible for shuttling nutrients into cells, either fat or muscle. A quick biology lesson: Every time you eat a meal, your blood glucose spikes, and when this goes up, so do your insulin levels. More calories at once means a larger spike in both. When these levels are sky high, it signals to your body to put nutrients into fat cells instead of muscle, causing an accumulation of fat, Seedman explains. The same thing happens when your insulin stays elevated for a prolonged period of time, which is why it’s important to let yourself become hungry before eating again, he adds. Aim for five to six meals throughout the day.
