In addition to HIIT, you'll want to consider adding some strength training to your program. Note that you can actually turn your strength training session into a high-intensity workout simply by slowing down your movements. Proper form is important, so to learn more about how to perform such exercises, please refer to my previous article, "Super-Slow Weight Training."
Certain foods can help you with weight loss and reduce belly fat. Spices contain the compound capsaicin which has been shown to increase the metabolism. This is the reason spicy food creates a temporary boost in the metabolism which is beneficial if you want to lose weight. Foods high in protein can also be helpful since it fills you up quickly and keeps you full for a longer time.
To address your sleep problems, I recommend beginning by realigning your circadian rhythms to the natural rhythm of daylight and nightfall. Without this synchronization, aspects of your waking/sleeping system will be working at the wrong time, making it difficult to sleep at night, while increasing daytime sleepiness. For an in-depth explanation of how this works, and why it's so critical for your overall health, please see my interview with researcher Dan Pardi. Three key factors to keep in mind are as follows:
Testing your limits brings about than just bragging rights. Lifting a heavier weight for fewer reps burns nearly twice as many calories during the two hours after your workout than lifting a lighter weight for more reps, according to research published in the journal Medicine & Science in Sports & Exercise. Feel smug in the knowledge you’re still torching calories in that 10am meeting.
Eat More Produce. Eating lots of low-calorie, high-volume fruits and vegetables crowds out other foods that are higher in fat and calories. Move the meat off the center of your plate and pile on the vegetables. Or try starting lunch or dinner with a vegetable salad or bowl of broth-based soup, suggests Barbara Rolls, PhD, author of The Volumetrics Eating Plan. The U.S. government's 2005 Dietary Guidelines suggest that adults get 7-13 cups of produce daily. Ward says that's not really so difficult: "Stock your kitchen with plenty of fruits and vegetables and at every meal and snack, include a few servings," she says. "Your diet will be enriched with vitamins, minerals, phytonutrients, fiber, and if you fill up on super-nutritious produce, you won't be reaching for the cookie jar."
