We evolved to find calorie-dense foods very tasty, and we don't have taste-receptors for micro-nutrients When humans (and most of their predecessors) did most of our evolving, low-calorie plants were plentiful. Sweet fruit wasn't usually around all year. Meat could be hunted, but it required plenty of energy and effort, and was usually quite lean. (Much ...

There's a 2005 study, and plenty of others, that show a clear dopamine release when sugar is ingested. This one shows that (in rats) it's on par with addictive narcotics. These results suggest another neurochemical similarity between intermittent bingeing on [sugar] and drugs of abuse: both can repeatedly increase extracellular [dopamine]. This ...

Unfortunately, for sake of a good answer, this could be so many different things. I'll try to highlight/mention as many as I can. To start, my best advice would talking with a good MD and ask about blood testing. That being said when the results come back I would recommend asking lots of questions and even consider having multiple MD's look at the results ...

When people talk about chocolate as a health food they are usually talking about dark chocolate, and in limited amounts. The current trend in coconut is around coconut water and coconut oil. With respect to dark chocolate, the health benefits in one study for example indicated that "Dark, but not white, chocolate decreases blood pressure and improves ...

It should be noted that it's very hard to make good studies showing wether exercise helps or not. All you can do is to ask old people about their history of exercise and correlate it with their health (or ask their relatives if they are dead.), but this correlation will contain unwanted components. For example; people who exercise often eat different food ...

I know that bodybuilding makes you heavier, stronger and more attractive, but is it really beneficial for one's health in the long run? Bodybuilding is not strength training. Bodybuilding is a very specific practice to improve one's looks. Strength training, by contrast, is training to improve the capabilities of one's body. Strength training is the ...

As with all health questions, the answer is to see a doctor. Dizziness could indicate that an insufficient amount of oxygen is reaching your brain. Causes of that can be as benign as being very winded or as serious as a heart problem. A physical examination by a doctor is the only way to know the cause is benign.

If you can't eat properly and exercise then no, there is no chance you'll transform to an athletic or physically fit body. I try to be helpful and supportive but aside from diet and nutrition, what other options do you have? Not having time really isn't much of an excuse. You could have decent progress with a commitment of this level: Training 3 times a ...

There can be a number of issues at work here, and to really understand what's going on, you'll need to talk to your doctor. It's not normal to always be fatigued in the way you are describing. There are a number of things you need to be asking yourself: Am I sleeping enough? Insufficient sleep causes a multitude of problems including fatigue. NOTE: ...

I don't think it will have an adverse affect on your fitness, but it will cause a dip in your energy levels, and make you more likely to reach for the wrong type of foods later, as you will be so hungry. What foods have you tried at lunchtime that are making you sleepy? Pasta, or anything that is too heavy is likely to have this affect. Try A salad, a ...

Injury sucks and it can never heal quick enough. To let it heal completely, you will need to have patience, though. First of all - and yes, I'm being preachy, bear with me - see a specialist. A trip to your physician is never really wasted time, even if he just tells you to slow down. In the worst case scenario you're really hurt and doing nothing can lead ...

Here's a blog article I haven't posted yet. Will weight lifting, strength training, etc, stunt my or my child's growth? If you (or your child) aren't sprouting up as quickly as the other kids and you've been lifting weights, it's easy to resort to believing the old wives' tale that you're short because of the weight training. We may never know how this ...

I would have to see the videos in question, but I suspect that most of the time they are talking about stretching to increase the range of motion. For the vast majority of the general public, this isn't going to be a problem as "normal" day to day flexibility should be more than sufficient for basic fitness and lifting routines. If, however, you have ...

"Injury" in the context of weightlifting typically refers to repetitive strain injuries. Lifting heavy weights is meant to stress the muscles, but too much stress (high weight or not enough recovery) can cause a muscle to tear. Heavy weights also strain the tendons and joints. You could encounter knee pain due to an overused patellar tendon, or shoulder pain ...

The advice contained on a number of health sites (eg NHS UK or Harvard Medical School) positively recommend progressive "resistance" training twice every week (in addition to cardio-vascular training) - because of the health benefits it brings. Not only are you conditioning your muscles, but also combating loss of bone density as well as strengthening and ...

I found out what is going on for me. In case others have questions similar to mine, this paper provides a pretty good background: Myalgic encephalomyelitis: International Consensus Criteria - Carruthers - 2011 - Journal of Internal Medicine - Wiley Online Library http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2796.2011.02428.x/pdf The specific issue ...

Geeky, If you sit all day, you'll develop a big waistline (sources: Live Science, NPR, and US National Library of Medicine). The main way to prevent that is to move around often, even if it's just for a few mins . Many of us are in similar situation as you (sitting for an extended period); so, we have an idea what you are going through. To keep a ...

What you're going through sounds similar to an experience that I had. I was a college athlete, I played basketball and tennis every day of the week and lifted multiple times a week. I had very bad pain in both of my knees and it was due to tendonitis above and below the knee cap. I was treated for this but the pain consisted. I finally went in and got my ...

We're getting more into diet than a fitness question, but the evidence is pretty clear currently that "gluten insensitivity" either does not exist or cannot be tested for. The only scientifically determined problem with gluten is celiac disease. Everything past that is a mix of marketers taking advantage of the panic and misinformed people advocating the ...

A few thoughts... Dehydration is a common trigger, and it's easy for that to happen if you work out for long periods. Milk of magnesia is your friend. It works by changing the osmotic balance of your intestines and keeping more water in the intestinal tract, making things softer. Great when you are having issues. I cycled regularly with hemmorhoids and not ...

This strategy looks like an emulation of the effect of a slingshot, a device which mainly sees use with people benching heavier weights (300+). I have not used this device, but I've spoken with users and they recommended it, mainly for dealing with shoulder injuries. When a shoulder injury occurs, especially for people benching these sorts of weights, it ...

Contrary to John's answer, I've also heard that aspertame is bad for constant consumption. Your question made me search more on the topic and came up with the following sources http://articles.mercola.com/sites/articles/archive/2011/11/06/aspartame-most-dangerous-substance-added-to-food.aspx: Excerpts from the source: How Aspartate (and Glutamate) ...

Tai Chi can help improve balance, mucscle strength, joint range of motion, relaxation, breathing and concentration. Elderly people often have joint problems that are painful and can prevent ...

The real answer can only be provided to you by a health professional, but I can give you some things to consider and educate yourself on in advance. Do some research and have a serious conversation with your doctor. You may already be experiencing insulin resistance. This means that your arteries are routinely being doused with fatty deposits that are ...

From obesity researcher Stephan Guyanet: Two new studies concurrently published in the Journal of Clinical Investigation last week demonstrate what I've suspected for a long time: brown fat can be 'trained' by cold exposure to be more active, and its activation by cold can reduce body fatness. Men's Health has a layman's overview of the same material. ...

It could be marked as non-potable for a variety of reasons. It could be reclaimed water, as defined: water that is not used for drinking, but is safe to use for irrigation or industrial purposes. I worked in a building that marked a lot of sources as non-potable because the pipes were leeching minerals into the water that were higher than what was ...

It seems unlikely to me that your body would actually still grow vertically at that age. However, if you have bad posture (such as a hunched back, or a office-job crooked neck), and you target this issue by doing exercises, you might eventually find yourself standing more upright than before, and therefore appear to be taller, even though your body hasn't ...

I am in the same situation actually as a high school student. I wake up at 4:30 in the morning sometimes to get to school and don't get home until 6 just to start my homework. I certainly find that eating healthier is a must. I know it is easy to succumb to the temptation of a bag of chips or a soda on the way home from school just to get some food into you, ...

What do you enjoy, or what looks most appealing to you? Do that. Doing something you enjoy, whatever it is, means you will be much more likely to stick with it over the long term. If you don't know what you enjoy, try short courses of a bunch of different things. Most will help you get in better shape, and when you find something you really like, stick ...

"Is diet soda less healthy than regular soda?" Hysteria around the aspartame in diet drinks is not justified by the evidence It is quite hard to prove a negative but the simple observation that hundreds of millions of people take aspartame containing drinks every day without apparently causing any notable epidemiological evidence of all the effects ...
