The Best Foods to Boost Metabolism and Shed Pounds. By Ori Hofmekler. What you're about to read here may change the way you think about food. Yes, once you see the facts, you'll realize that most of the products on the grocery shelves don't fit your biology. Most of today's dietary products are not designed to keep your body young. The genes that regulate your biological age are highly sensitive to your diet, as they're triggered or inhibited by what you eat, how much you eat, and how often. The point is: You need to know how your diet affects your biological age. You need to know what food keeps you young and what food is making you old. How Your Diet Affects Your Biological Age. It has been largely agreed that one of the most detrimental causes of aging is excessive calorie intake. Scientists speculate that humans have an overly strong drive to eat when food is readily available. And since people are surrounded today with calorie dense food, they tend to consume excess calories, which then cause them to gain weight, lose health, and age prematurely. Given this, many believe that calorie restriction is the most effective strategy to get in shape and counteract aging. But the calorie restriction theory is only partly true. It can't always predict whether you'll gain weight or lose weight, neither can it predict whether you'll get in shape or get out of shape. You can be on a low calorie diet and fail to lose weight, and you can be on a high calorie diet and yet manage to slim down. Emerging evidence indicates that there is another powerful factor behind the scene – one that overrules and dictates your energy expenditure, metabolic rate, body fat percentage, physical shape and eventually your biological age. That factor is the system that controls your hunger and satiety signals. And as you'll soon see, it has nothing to do with your calorie intake, but rather with what you eat and how often. How Your Hunger- Satiety System Affects Your Physical Shape. Your hunger- satiety system consists of multiple neuro- peptides that act to initiate or terminate your feeding. These are your hunger- satiety hormones. ![]() ![]() Their signals are integrated by centers in your brain to modulate how you consume, spend or store energy. The balance between these signals dictates whether your body is in a fat- burning or a fat- storing mode. In order to maintain a healthy body weight, your hunger and satiety signals must continually adjust your food intake to your energy expenditure. Any imbalance between these two will affect your fat stores and physical shape. Obesity, for instance, is a result of a disrupted energy balance in which a surplus of accumulated food energy is stored as body fat. Again, your physical shape seems to depend on the ratio between your hunger and satiety hormones and so is your biological age. Both hormones regulate your eating behavior and metabolic rate, albeit with opposite effects on your body. Hunger Hormones vs. Satiety Hormones. Your hunger and satiety hormones are constantly clashing with each other like two armies at war. And the consequences of that hormonal clash are manifested in your body. Hunger hormones tend to slow your metabolism and increase your body fat whereas satiety hormones tend to boost your metabolism and decrease your body fat. Simply put, if your hunger hormones get out of control, you'll be prone to suffer from a sluggish metabolism and excess body fat. ![]() How long does Tramadol stay in blood? After more than a couple of days, it’s unlikely that Tramadol will be detected in the blood. This detection window for. Beautifully stated, moonwest. I like your emphasis on the "goodness of others"! You are right to emphasize that and to contrast it to the "turn a buck" medical and. Heroin effects may last anywhere from a few minutes to hours, but the drug can stay in your system for much longer. Many people are surprised when they hear that the. And if your satiety hormones take over, they will counteract the effects of your hunger hormones to allow you greater energy and a leaner healthier body. But note that your hunger hormones are not inherently bad; when balanced, they play important roles in your metabolic system. Under healthy conditions they may even help you burn fat. The hunger peptide ghrelin, for instance, is a most potent trigger of your growth hormone – it binds to growth hormone secreagogue receptors (GHS- Rs) and increases its release by six fold. ![]() Indeed, fasting and hunger boost your growth hormones and potentiate its actions to burn fat and repair tissues more efficiently than drugs – naturally and safely without side effects. Your hunger hormones are part of your survival apparatus. They relate to your satiety hormones like yin to yang. They keep you alert and give you the drive to search for food along with the desire to achieve. ![]() ![]() And they balance the actions of your satiety hormones which tend to calm you down. But if you let your hunger hormones get out of control, you'll experience chronic hunger, diminished energy, metabolic decline, decreased libido and increased tendency to gain weight. You need to know how to manipulate both types of hormones to work for you. And you certainly need to keep your hunger hormones under control. ![]()
But how can you do that if you don't even know what causes your hunger hormones to get out of control? What Causes Your Hunger Hormones Get Out of Control? Normally your hunger hormones are highly responsive to feeding – their levels increase during fasting and reduce upon food ingestion. Your most notable hunger hormones are ghrelin, neuropeptide Y (NPY) and agouti- related protein (Ag. RP). During fasting, your hunger hormone ghrelin peaks, boosting your growth hormone to initiate fat burning. Meanwhile, your remaining hunger hormones are continually balanced by your satiety hormones (adiponectin and glucagon- like peptide). ![]() This keeps your hunger under control and potentiates your sensitivity to satiety signals. Then, when you resume eating, your hunger hormones decline – allowing your satiety hormones to kick in and act to boost your metabolism. That's how your hunger- satiety system works under healthy conditions. It allows you to burn fat when you don't eat and it acts to boost your metabolism when you eat. Hence, a win- win situation. But your hunger- satiety system can only function well as long as your diet is adequate. If your diet is high glycemic and your feeding episodes are too frequent, your hunger- satiety system will be utterly disrupted. Frequent consumption of high glycemic meals impairs your key satiety hormones insulin and leptin, leaving your hunger hormones unopposed and dominant. When insulin is impaired (such as in cases of insulin resistance), ghrelin levels remain elevated even after meal consumption – a condition that leads to chronic hunger (mostly for carbs), excess food intake and undesirable weight gain. This issue has been widely overlooked, perhaps because people normally like to consume baked goods and candies on a daily basis and even more so during celebrations. But the evidence leaves no doubt: frequent consumption of high glycemic foods jeopardize your satiety apparatus and put your body under the tyranny of your hunger hormones. To prevent that you need to avoid high glycemic foods and resist cravings for sweets. You need to know how to boost your satiety hormones and let them take control over your metabolism. ![]() How to Boost Your Satiety Hormones. Your satiety hormones include insulin, leptin, adiponectin, cholesystokinin (CCK), glucagon- like peptide (GLP), PPY and melanocortin. When potentiated to counteract your hunger hormones, they help increase your energy expenditure, stimulate your thyroid, enhance your sex hormones, lower your stress hormones and increase your capacity to burn fat. The three main factors that boost your satiety hormones are: – Food restriction– Exercise– Weight loss. Food restriction, exercise and weight loss increase the sensitivity and effectiveness of your insulin and leptin while potentiating the actions of your other satiety hormones. This means that with proper diet, exercise and restoration of a healthy body weight, you can increase the efficiency of your satiety hormones to allow you be at your peak physical potential. But how do you put this in practice? How do you put your satiety hormones in charge? There are three ways to achieve that: Eat satiety foods Avoid hunger foods Train your body to endure hunger Eat Satiating Foods. The food that promotes satiety most is protein. It yields satiety more effectively than carbohydrates or fat. Out of all proteins, the one with the fastest satiety impact is whey protein – that's if the whey is whole and non- denatured. Studies reveal that consumption of whey protein before meals can swiftly boost the satiety peptides CCK and GLP- 1, which have been shown to decrease food intake and increase weight loss. Whey protein is also beneficial when consumed before exercise. Having a small serving of whey protein (with no sugar added) about 3. A pre- exercise whey meal has also shown to boost the body's metabolic rate for 2. Other satiety- promoting foods are low glycemic plant foods including raw nuts, seeds, legumes, roots, cruciferous vegetables, tomatoes, eggplants, grasses and green leafy vegetables. Being low glycemic and fibrous, these plant foods are a great fit for your insulin and leptin as well as your whole satiety system. Nuts and seeds trigger PPY – a satiety peptide which is highly sensitive to dietary fat. PPY shifts your cravings from carbohydrates to fats and increases your metabolic capacity to convert fat to energy. That action counteracts your hunger hormones, which typically shift your cravings towards carbohydrates. Note that it's the shift towards refined carbohydrates that has been linked to chronic cravings and excessive food intake. This is the reason why once you open a bag of potato chips and start crunching, you may find it difficult to stop. And note that your muscle isn't programmed to do well on hunger foods; it rejects fructose and has a limited capacity to utilize high glycemic foods. But your muscle literally thrives on satiety foods. Combinations of whey protein and berries, eggs and beans or meat and nuts have unmatched muscle nourishing properties. Furthermore, being satiety oriented, these food combinations promote the right hormonal environment for muscle rejuvenation and buildup. Does Building Muscle Burn Fat, Calories & Increase Metabolism? How many times have you read an article about weight loss that contained a list of “fat burning tips” or any kind of advice aimed at helping you lose fat better, faster or easier? And how many of those times did you come across the suggestion that weight training is super important, because it will allow you to build muscle? The human body naturally burns more calories each day to maintain a pound of muscle than it does to maintain a pound of fat. Therefore, the more muscle you build, the more calories your body will naturally burn each day at rest. Which means, just by building muscle, you’ll significantly increase your metabolism and turn your body into a calorie burning, fat melting machine? Technically speaking, it kinda is. For example: FACT: Your body really DOES burn more calories maintaining muscle than it does maintaining fat. FACT: This means that YES, the more muscle you build, the more calories your body will naturally burn each day on its own. FACT: Which means that building muscle DOES increase your metabolism. FACT: And this all means that building muscle definitely has the potential to help you lose fat. With me so far? Good, because here’s where it all starts to get a little screwy. You see, the problem with this theory/advice isn’t so much that it’s wrong but rather that it’s just highly exaggerated, way over- hyped (usually to sell some crappy product), and extremely insignificant in terms of the actual effect building muscle will have on helping you lose fat. How Many Calories Does Muscle REALLY Burn? To get to the root of the problem, you need to understand how many calories muscle actually burns. Depending on where you get your diet and fitness information from, you may come across the suggestion that 1 pound of muscle burns as much as 2. If this were true, then building 5lbs of muscle would lead to as much as 5. Unfortunately, muscle doesn’t burn anywhere near that amount of calories. Instead, based on all the research I’ve seen, the actual numbers are more like this! I can feel my metabolism increasing as we speak! This would mean that building 5lbs of muscle would lead to you burning an additional 2. Building 1. 0lbs of muscle would lead to a whopping 5. You’d have to build the maximum amount of muscle that your body is capable of building in your entire lifetime before the amount of calories it burns gets even close to the crazy “significant” levels people incorrectly assume. And in case you’re wondering, 1 pound of fat burns about 2 calories at rest. So yeah, muscle does burn more calories than fat. I mean, if you lost 5lbs of fat and gained 5lbs of muscle, your metabolism would increase by a whole 1. I think that deserves another sarcastic wow? It’s pretty simple. While I will always recommend weight training during fat loss (primarily because it’s a requirement for maintaining muscle while losing fat), the idea that it’s helping you build muscle and this muscle is having a significant fat burning effect is mostly just exaggerated bullshit that is often: A) Repeated by people who don’t know what they’re talking about (like most fitness myths are). B) Used to help sell some junky product built mostly on hype and fancy marketing. Potentially. However, while every little bit helps, it’s unlikely it will ever make anywhere near enough of a difference to truly have a significant effect on your fat loss efforts. Instead of trying to increase your metabolism, you’ll be better off trying to eat less total calories (or trying to increase activity to burn more of them). This will always have the legit significant fat burning effect you’re looking for. More about that here: How To Lose Fat.
