Probably more than you want to, in all the wrong places, and you could do harm to your bodily systems. Fasting causes many unwanted changes, including reduction in metabolic rate, which is something you don't want if you are trying to lose weight. It is better to eat sensibly, satisfying your need for energy and protein while avoiding 'excess calories' from too many sugars and fats. You weight loss on any diet would depend on a lot of variables, such as how much you weigh, how tall you are, what is your metabolism like. However, I would like to point out something very important. If you stop eating for a long time, your body interprets this as being a time where food is hard to find. Hence, it will put itself into survival mode, which means it will take as many calories as it can from any food ingested. Consequently, when you start eating again, you will put back on the weight you lost and then some. Your body will just think "Oh food! Better be prepared for next time I don't have some!" This will eventually lead to weight gain. Thus, if the goal is weight loss, an healthy alimentation (less sugar, whole grains, lots of fruits and veggies and some proteins to keep you full) and some exercising will be more profitable in the long run.
But the source of calories obviously matters for other reasons. One, says Katz, is that "the quality of calories is a major determinant of the quantity we ingest under real world conditions." First of all, no one overeats veggies, so on a practical level, that’s a non-issue. “But where the calories come from does matter in that they influence satiety,” he adds, and this is partly psychology and partly biology. In fact, the food industry has carved out a whole new area of food science to study the “bliss point,” in which foods are created to increase the amount it takes to feel satiated and full. On one hand, says Katz, “we have the 'bliss point' science to tell us that the food industry can process foods to increase the calories it takes to reach satisfaction. We have the reciprocal body of work, including the Harvard study of the ONQI, showing that 'more nutritious' means, among other things, the opportunity to fill up on fewer calories.”
Like protein, fiber slows the rate at which your body plows through carb calories so you feel full for longer and maintain steadier blood sugar levels, one reason why research consistently links fiber intake to weight loss. That means fibrous whole grain bread tends to be a better choice than white bread and also explains why fruits, which contain fiber and valuable vitamins in addition to sugar, beat straight-up candy every time.
“This is an adaptive system,” adds David Allison, PhD. “For every action there’s a reaction; that’s a law of physics, not of biology, but it seems that it also works in biological systems. This is why we often overestimate quite radically an effect of a particular treatment.” He points out that public health campaigns that, for example, urge people to take the stairs instead of the elevator or go on a nightly stroll – or, for that matter, even eat fewer calories – are unlikely to work, since they may fail to take into account the body's compensatory mechanisms that can totally counteract the effect.

Want to lose that belly fat? In your dreams! Seriously, though: a good night’s sleep is one of the best ways to get rid of that extra fat around your waist for good. Among the 60,000 women participating in the Nurses’ Health Study, those who snoozed for fewer than five hours a night were at the greatest risk of becoming obese and gaining 30 or more pounds over the course of the 16-year study period when compared to those who slept for seven or more hours.
Make sure that you don't get hungry by eating small portions throughout the day at regular intervals. Between your meals, eat a 150-calorie snack to keep your metabolism burning and to stave off hunger. Be sure that you don't eat a fattening snack such as sweets or crisps. When you're hungry, your body conserves calories and slows down your metabolic processes.
93. Look At A Motivational Image – Print out one of these 10 fitness motivation images to look at every day. Pick an image that’s positive and inspiring. If possible, make it specific to things you like to do. For example, find a cool picture of a surfer riding a wave, a bodyweight exercise you want to accomplish, your favorite athlete, or a rock climber scaling a mountain wall. Looking at that image may inspire you off the couch and into the gym.
On the rare chance that you did lose too much weight and want to put on some muscle, Jim says to slowly add in more (healthy) calories, about 200 to 300 extra a day. "Stick with adding in mostly lean proteins, whole grains, fruits and vegetables, and low-fat dairy," he said. When it comes to exercise, he recommends weight training two to three times a week.
Figure out how many calories you should eat each day to lose weight. Losing weight isn't all about weight. The more aware you are of the calories in the food you eat, the more easily you'll be able to eat the right amount of food and do the right amount of exercise to drop a couple of pounds. Take your food journal and look up each item individually. Keep a running tally and add up your calorie total for the day.
Positively stay away from fast food. In addition to cooking everything in trans fat, fast food burgers, fries, and shakes (or burritos, mac 'n' cheese, or sandwiches) are whoppers when it comes to salt and sugar. They are essentially empty carbs, with no real nutrients to them. If you're serious about shedding those pounds and getting your weight back on the right path, you'll stay away from fast food.
84. Take Progress Pictures – Every week, or month, take a shirtless picture of yourself to see your change over time. This comes back to motivation. Since you see yourself in the mirror every day, you might not notice the subtle changes in your aesthetics and physique. Taking pictures of yourself lets you compare where you started with where you are and where you’re going.
And what fat loss comes down to is simply a caloric deficit. Which means either burning more calories, eating less calories, or a combination of the two. And when you get down to it, it’s just a whole lot easier for most people to eat (for example) 500 less calories per day than it will be for them to try to burn those same 500 calories every single day. That’s why diet alone gets the job done just fine, and diet and exercise combined gets the job done too. But exercise alone? That’s the least effective of the group by far.
This will require you to improve your posture. But, do work on your posture as standing up taller can make you look 5 pounds slimmer. Stand in such a way that your pelvis is relaxed. You can also stand against a wall to check whether your posture is straight. Make sure that your back is pressed up against the wall with no more than an inch between the wall and your lower back. A wider gap means your pelvis is not straight.
