Yes, there is rest built in—two days, to be exact—but not until you’ve put in seven straight days of pedal-to-the-metal work. Rest on days 8 and 13 to allow your body to temporarily recover from the grind of the program. This will help you bank more energy for the work days that follow. These rest days are mandatory. For those of you hitting the panic button, don’t fret—12 out of 14 days at these intensities will still be plenty adequate for getting your shred. Remember: your body changes while it recovers, not while you train. So, consider these two days your chance to bust into the gym a little more ripped on days 9 and 14.
Ah, the über-popular “know your why” strategy. One Brown University study found that when people are motivated to lose weight for appearance and social reasons, they stick with their weight-loss habits for significantly less time than those who are motivated by their health. After all, these external motivators (like looking a certain way or fitting into a cultural ideal) aren’t going to get you going when you’re feeling down, have had a bad day, or are frustrated with a plateau, Albers says.
But before we get into how to go about losing weight, please consider this: Weight loss isn’t a healthy goal for everyone, Susan Albers, Psy.D., a psychologist at the Cleveland Clinic specializing in body image and eating issues, tells SELF. “I work in a medical facility,” she says. “I have access to people’s blood work. You can be healthy or unhealthy at every size.”
"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."

1. The side plank exercise is the best way to reduce belly fat. There are only two points of contact with the floor which helps the core muscles to contract even harder. Lie on your side with your legs top of each other, rest on your lower forearm that is bent on the elbow. Force your upper body off the floor by using your forearm and place other hand on your hips. You should resemble a diagonal line from head to toe. After you lift your bodies just hold it for 30-60 seconds.
Snacks are misunderstood in the weight-loss world – many people don’t realize that snacks can help you lose weight rather than gain it. If consumed in moderation as a way to relieve minor hunger pangs, snacks are a perfect bridge between meals and prevent you from consuming too many calories at your next meal. Choose snacks between 100 and 150 calories. Some or Dr. Smith’s favorites include shrimp cocktail, olives stuffed with blue cheese, an English muffin pizza, or a banana with dark chocolate. Try these shredder snack recipes. 
Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index (for instance, asparagus is lower on the glycemic index than a potato) or lower in carbs per serving than others. Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. They may be added back, such as in “enriched” bread.
During the first week of a reduced calorie and carbohydrate diet, you will flush a lot of excess water and lose weight rapidly. This is neither unhealthy, nor an indication of what your rate of weight loss will be like during weeks 2 and 3. With that said, men should expect to see an 8 to 12 pound loss during these 3 weeks, and women will likely lose 5 to 10 pounds. 
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it’s that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, a study published in Diabetes Care revealed that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.

Another strategy to keep your metabolism off-kilter is to take your body on a calorie roller coaster. As you start off the Shred Diet at Week 1, you’ll slowly reduce your calorie intake. This will be a difficult uphill battle — the steep climb of the roller coaster. Luckily, this effort is only short-term; halfway through the diet, around Week 3, you get to bring the calories back. As you glide down the roller coaster’s hill, you can indulge in your favorites like pizza and pasta (in healthy moderation), and your metabolism will run overtime. This roller coaster of calorie consumption is the perfect metabolic recipe for shedding fat. 
"When we’re lacking in sleep, our body’s hormones get thrown off balance which can impact our hunger levels the next day. We all have two hormones that affect our appetite: ghrelin and leptin. When we don’t get enough sleep, our ghrelin levels (the hormone that makes us feel hungry) rise, and our leptin levels (the hormone that makes us feel full) drop. This means that when we’re awake, we tend to eat more but feel less satisfied. Try going to bed a little earlier than usual to avoid this imbalance and remember to remove any distractions that might prevent you from nodding off."
