IKS: It was! People said, “Well, when is this gonna be a book?” Once again, no intention of being a book, but I called my editor and I said, “Listen, something’s going on here. These people are losing a ton of weight, they love it, they tell me they don’t feel like it’s a diet, it’s like just eating regular food.” And voila! Here is Shred, and it’s number one in the country right now.
And that’s not just the junk food sabotaging your diet, or the time suckers keeping you from working out. We’re also talking about the fad diets, fitness trends and questionable studies that have made reaching and maintaining a healthy weight more confusing than ever by promising this superfood or that super intense workout is the quick fix to tip the scale in your favor. (They’ve also spawned a $66 billion weight loss market.)
What does a HIIT workout look like? You could jog for two minutes, sprint for one minute, jog for two minutes, sprint for one minute. Or you could do a HIIT workout on a bike, or by running up stairs and then jogging back down. The key is that you go relatively all out for a short period of time, then recover by maintaining a moderate level of intensity, then go again.
A study in Psychosomatic Medicine confirms the link between stress and weight gain, revealing that women who are most vulnerable to the effects of stress are more likely to have excess abdominal fat and higher levels of the stress hormone cortisol. One reason could be that women tend to eat more, especially sweets, on days they are stressed, according to a study in the journal Psychoneuroendocrinology.
2. Cut out some carbs. A simple, short-term trick to losing weight is to cut back on carbs until you’re at your goal. Eat lean protein and vegetables at every meal and limit carbs to before and after your workouts, and you’ll probably see the scale shift rather quickly. Easy, low-carb meal ideas include egg-white omelettes with vegetables, Whey Protein Powder shakes made with water, salads with lean protein (chicken, tuna, or turkey), and grilled or broiled lean beef, poultry, or fish with vegetables.
Say cheese! Adding some extra calcium and vitamin D to your diet could be the key to getting that flat stomach you’ve been dreaming about. Over just 12 months, researchers at the University of Tennessee, Knoxville found that obese female study subjects who upped their calcium intake shed 11 pounds of body fat without other major dietary modifications. To keep your calcium choices healthy, try mixing it up between dairy sources, calcium-rich leafy greens, fatty fish, nuts, and seeds.
Incorporate at least two additional days of exercise -- cardio, yoga, or Pilates -- outside of the three workout days that you perform the 30-Day Shred program. According to the Centers for Disease Control, adults between the ages of 18 and 64 require 150 minutes of moderate intensity aerobic fitness every week and two to three days a week of strength training.
For even more impressive effects on body composition: aim for exercise forms which elicit a positive hormonal response. This means lifting really heavy things (strength training), or interval training. Such exercise increases levels of the sex hormone testosterone (primarily in men) as well as growth hormone. Not only do greater levels of these hormones increase your muscle mass, but they also decrease your visceral fat (belly fat) in the long term.
And so my Twitter followers and people on Facebook, they lost so much weight in such a short period of time—they were losing four pounds in five days, five pounds in seven days; the results were outrageous—they kept asking me for more. And so I kept tweeting them more and emailing them. Before I knew it we had 5,000 people across the country, [and] as far away as the UK, who were on Shred. And they were losing weight hand over fist.
A calorie isn’t always a calorie. Eating 100 calories of high fructose corn syrup, for example, can have a different effect on your body than eating 100 calories of broccoli. The trick for sustained weight loss is to ditch the foods that are packed with calories but don’t make you feel full (like candy) and replace them with foods that fill you up without being loaded with calories (like vegetables).
"Crash diets (dramatically cutting down how much you eat) might help you to lose a few pounds at first, but they’re hard to sustain and won’t help you keep the weight off. It might seem like a quick and easy option, but eating too few calories can actually do more harm than good. If your calorie intake dips too low, your body could go into starvation mode. This will slow down your metabolism, making it harder for your body to lose weight. Make sensible, healthy changes to your lifestyle that you can stick to and avoid the fad diets."
