This is not true. Your body will process the food that you ingest, and if the caloric intake of the food is greater than the amount of calories burned during the ensuing exercise, you will gain weight. You can have some carbohydrates before your workout if you find that your diet doesn't supply you with enough energy to not feel weak or excessively tired ...

In a sense, yes it does. It's not a permanent increase, you simply keep on burning more calories than your resting rate until your body returns to baseline. The type of exercise (the shorter, higher intensity workouts are better) also influences how long this occurs. In this study : ...

You have already listed some good points. I don't believe eating spicy foods has any long term effect on metabolism. It's true that spicy foods increase the body temperature. Calories must be used to generate that extra heat. After a few minutes, the heat goes away, so what good does it do? Eating regularly makes your body believe that food is abundant and ...

This is a complex question, and no one has the complete answer, but a recent study compared the metabolic rate of a hunter gatherer culture still in existence with the metabolism of sedentary westerners and found that "daily energy expenditure of traditional Hadza foragers was no different than that of Westerners". Similarly, a study found that the ...

It takes 30 to 40 minutes for food to digest in your stomach and 3 to 4 hours for it to absorb in your intestines. I agree that there is no strict formula for this, since it also depends on what you eat and how you intend to expend that energy. From my experience if I eat a large meal which is heavy in carbohydrates I see my best performance with a high ...

This is a situation where she needs to take a step backward in order to move forward. The worst thing she could do is lower her net caloric intake again via diet or lots of exercise, as that will just reinforce "starvation mode" to her body. I would suggest she starts by eating natural whole foods to fill for a few weeks. Its probably best to avoid tracking ...

Basal Metabolic Rate (BMR), and it's sibling, Resting Metabolic Rate (RMR) refer to the amount of Calories your body will burn without any work done. They are similar, and for convenience sake most people are referring to RMR when they talk about daily Calorie requirements. Several things do affect those values, such as: Proportion of lean body weight to ...

I've been told that the body can store up to 3 days of glycogen, and consequently takes about that long to transition into ketosis. You can feel lethargic and possibly even nauseous during this time (some of my friends experienced the latter where I only experienced the former). The initial stages of ketosis are rather inefficient, and it takes about three ...

In an effort to support the very thorough answer given by @Berin Loritsch, here is a more explicit conceptual picture. The mass food that is taken into the body (A) has 3 potential fates: 1) it will not be digested or absorbed by the digestive system (gut) and will pass out of the body via the anus. There are many factors that affect this but mainly it is ...

In a very real sense, you may be reading more into these numbers than is there. First and foremost, our bodies are designed to be efficient at maintaining its operation. That includes the amount of body fat you have, how much energy it expends, etc. Your body has adapted to the approximately 2000 Calories you are consuming. At your activity level, height ...

To answer that question it would require a long discussion about the pancreas, the colon, the kidneys, the liver and general digestion. I believe the thyroid also has a role to play. The one organ that is most involved with regulating the fat stores is the pancreas. When your body has a surplus of blood sugar, it secretes insulin which stores the excess ...

There are (at least) two different ways to look at this. Adding muscle mass => higher basal metabolism Post-workout metabolic effects The first one being that the more muscle you have, the more energy your body will demand to maintain itself. You can probably find a basal metabolism rate calculator, and input different values of your weight to see how ...

Chris made a very good comment on your question. I have the same body structure like yours is. I found some advantages of being an ectomorph. You can eat whatever you want; till it's just a matter of increasing fat on your body due to your eating habbits. You will never have to struggle to lose weiht. You have fewer chances of getting affected by those ...

Ectomorphs automatically win when it comes to long distance running and rock climbing, as well as any other sport where being light is an advantage. Being unable to gain weight easily means strength gains are almost entirely without a matching weight gain. That's great if you want to keep your own weight low while getting stronger. Also, a lot of designers ...

Go back to the doctor, get other bloodwork done. Women are prone to a couple of different endocrine issues that are related to weight gain - namely PCOS and hypothyroidism. Both are very often under- or misdiagnosed. For PCOS, you need at least the following bloodwork - DHEAS, fasting insulin, and fasting glucose. Ideally, she should also get free ...

I agree with everything md5sum says but there are a few thing's I'd add. What the link points out is that, while aerobic exercise burns more calories during the exercise (and soon afterward), the anaerobic exercise continues to burn calories well after the exercise (up to 38 hours) because your body uses a lot of energy during recovery (reversing the ...

Using more and different muscles will cause you to burn more calories and will increase your Excess Post-Exercise Oxygen Burn (EPOC). I would definitely advise you to work your entire body, and not just running. I work my upper body every other day and work my legs and run on the days between.

Exercise is highly specific, and will only affect the muscles you exercise--not all cells in the body. That said, there are two types of hypertrophy involved in building muscle: Myofibrillar hypertrophy which builds more protein pairs and makes each muscle cell stronger. This is built using short rep schemes (1-5 reps) with high weight. This improves ...

One way is build more muscle. At rest, muscle burns more calories than fat. When doing exercise, try and stay in the 60%-80% of max HR range. This is a fat burning range, and when you get beyond that you move into glycogen metabolism. If you can get a higher Basal Metabolic Rate (BMR) by building more muscle, then sleeping burns more calories than ...

I cannot answer all but I will do what I can... Drinking hot beverages doesn't aid in the digestion, but it increases your metabolism. I drink hot water in the AM to help 'induce' a 'flushing' of my excess before big races. Drinking water near room temperature allows the water and fluid to be absorbed into your body quicker and easier. Thus room temp. ...

I would recommend eating smaller meals more often. Eating one very large meal and one small meal isn't good based on my experience I'm the same way, except I only eat about 3800 calories a day. I'm 6"2' (1.88m) and 155 pounds (70kg), though My body weight back before I started lifting and when I only ate about 2200 calories per day was 130 pounds (59kg). ...

Well the first part is true for some people. It's a fact that not everyone responds to diet and exercise the same way, and that's a reasonable hypothesis for why some people react in a certain way. The last part about alternating high and low calorie diets being the only way to lose weight and gain muscle consistency isn't true. For weight loss it might ...

Because the english wikipedia is pested by bad references (mostly third class fitness sites that oversimplify the whole thing) I will cite from the German Wikipedia (with translation by me). Diese Idee ist heute medizinisch widerlegt. Das Konzept taucht heute fast ausschlie├člich im Fitness-Bereich auf, um ein dem K├Ârpertyp angepasstes Trainingsprogramm ...

Your question is in some ways quite broad, but in the narrow sense: yes, long distance slow paced steady-state cardio like marathon running absolutely reduces muscle mass, and has a distinctly diminished return on investment after you've been doing it for a while. That is, if you work yourself up to running X miles every week, staying at X miles each week ...

Greg Knuckols wrote a good article regarding the differences between men and women as it pertains to weight training: Muscles behave the same on everyone: all that matters is cross-sectional size of the muscle and neural stimulation. Women's skeletal structures are different where the legs join the hips: this affects what correct form looks like for a ...

Somatotypes are bunk that were initially used as a psychology measurement. There is no documented evidence that a person is an ectomorph, mesomorph or endomorph and unable to change. While certain characteristics like height are fixed, things like weight and muscle/fat ratios are dictated much more by the exercise a person performs and the diet they eat. ...

I understand that there is a window (not sure if it's 15 minutes exactly, I suspect longer, and there's probably a gradual drop-off) after a heavy strength-training session in which your body is in a hormonal state that causes it to route most e.g. carbohydrates into repair and refueling your muscles & supporting systems, rather than routing it into fat ...
