5 Worst Nutrition Tips EVER!

badideaThe only thing more astonishing than the amount of misinformation about nutrition the willingness of people to follow it. Over the years, there’s been no shortage of terrible nutrition advice – and these are some of the biggest offenders.

  1. Don’t eat egg yolks. Why this advice sucks: It’s no secret that eggs are high in cholesterol and that most of the cholesterol is contained in the yolk. But dietary cholesterol tends to have a fairly low impact on the cholesterol levels in blood. Some people with high cholesterol diets have low blood cholesterol and some people with low cholesterol diets have high blood cholesterol. Beyond cholesterol, the yolks are packed with other important nutrients that are essential for your diet. Unless you have high blood cholesterol, eating the egg yolk is a actually nutritional benefit.
  2. Eliminate fat. Why this advice sucks: Decades ago, reduced fat diets and low-fat foods became extremely popular. Unfortunately, much of the low-fat hype and low-fat foods have survived through present day. In reality, fat doesn’t make you fat. Consuming more calories than you burn results in weight gain. Our bodies need healthy, essential fats – like those found in avocados and nuts and extra virgin olive oil. While fats are very calorie dense and should be consumed in moderation, opting for low-fat foods won’t do much to help the cause. In addition, many reduced fat foods are loaded up with sodium or sugar to help replace the favor. And that’s definitely not a good thing.
  3. Don’t eat carbs. Why this advice sucks: Carbohydrates, as it turns out, are crucially important to proper bodily function. Instead of reducing or eliminating all carbohydrates, it’s much wiser to eliminate simple carbs (i.e., sugar, candy, white rice, white bread, etc.) in favor of complex carbs (i.e., brown rice, whole wheat bread, etc.). By eliminating carbohydrates entirely, you won’t have the energy to power through your workout or any other physical activity. In addition, a lack of blood sugar from a low-carb diet can severely slow and limit brain function. Opt for complex carbs.
  4. Don’t eat after 7PM. Why this advice sucks: Science just doesn’t back this claim up. Studies have found that what you eat – and how much of it – is far more important in determining weight gain than meal timing. There’s nothing wrong with eating late at night. If you are eating late at night, pay special attention to what you’re eating. It’s not a green light to mindlessly snack on a bag of chips. Instead, continue to make smart nutritional choices all hours of the day.
  5. Detox your body regularly. Why this advice sucks: Detox diets are a marketing gimmick, plain and simple. Your liver and kidneys detoxify your body naturally. This isn’t accomplished by a packaged juice product that’s devoid of the essential nutrients your body needs. Not only are detox diets unhealthy and counterproductive, but they’re also downright miserable.

  1. Richard Fountain says:

    Not sure if it is correct or not but you shouldn’t eat carbs after a certain time of day and they should taper down throughout the day. Is this correct? Xx

  2. What about the one that says to drink juice from half a lemon in a glass of water every morning (some say a spoonful of apple vinegar instead) ?

  3. A friend once told me to start smoking. I just looked at her like the idiot she was.

    • this thinking probably comes from the known fact that people gain weight after they stop smoking. Some people thus make the assumption that smoking renders you thinner. However what they don’t know is that smoking alters your gut flora (it becomes similar to an obese person’s) by killing some of the important bacteria in their gut and once they stop smoking the wrong type of bacteria grow back in the place where the “good” types should be altering a persons metabolism so he/she gains weight faster (can happen after long duration antibiotic treatment as well)
      so a non smoker that starts to smoke will not lose weight, but when he stops again he’ll gain weight…
      you shoul let your friend know

  4. Sorry, I’ll jave to call BS on your low carb theory. The science I read proves the opposite of what you said. Our bodies opperate perfect without any carbs. Our bodies AND BRAINS actually function on ketones rather than insulen. Ketones = broken down fat.

    • Ruan … Are you a biochemist? Because at the moment I don’t think you know the difference between a potato and a stun gun -_-

      Carbohydrates are essential for every known cell they are hydrocarbon chains (usually circular in form) with hydroxide groups attached. When these hydroxide groups react together they form water and are stored as long chain carbohydrates (hydrated carbon) and when they split (hydrolysis (latin: water-splitting)) hence why you need to break down the long chains to digest them.

      When fully broken down they are glucose molecules, these then undergo Glycolysis to form ATP (the ‘fuel’ of the cells) and Pyruvic acid with oxygen or lactic acid without oxygen.

      Keytones on the other hand are classified as an oxygen molecule double-bonded to a carbon that is then single bonded to two other atoms (regardless whither they are in a chain or not). Although many sugars – such as fructose – are ketoses they are more distinctly active as carbohydrates, and keytones are formed from carbohydrates.

      So in conclusion, I’d love to see how long you live without carbohydrates! ๐Ÿ˜›

      From – A natural scientist ๐Ÿ˜‰

    • When did you forget your biochemistry lessons? Or didn’t you take them at all?

      The brain is probably the most energetically consuming organ of the human body: it requires about 20% of the glucose and oxygen that enters the body. While it’s true that the brain can obtain energy from ketone bodies, it only does so during severe starvation or very low glucose intake, as its favorite “fuel” by excellence is glucose itself. The same for the rest of the body: glucose is the main immediate source of energy for the cells, and only when its levels drop and not replenished the body starts using its stored forms of energy (any remaining glycogen, fat deposits and, when starvation lasts too long, even structural proteins).

      Ketone bodies are produced when the levels of acetyl-CoA are increased in the cells breaking down both carbohydrates and fat. Due to their chemical nature, ketone bodies can travel freely through the bloodstream until they are absorbed in tissues and used as a source of acetyl-CoA. However, ketone bodies are not a primary source of energy for cells because of the main adverse effect of their lasting presence in the bloodstream: ketoacidosis (the blood’s pH goes down, which has an effect on the structure of plasma proteins and the solubility of some compounds found in blood).

      Do you see it now?

  5. Davey is pretty much right about everything here.

    In regards to the carbs cutting out the simply varieties is the best option and keeping to complex is advised.

    Ruan cutting out carbs completely is extremely difficult and even dangerous long term. Yes our bodies can function without them by consuming stored fat but those “ketones” you mentioned are the byproduct of this process not what causes it.

    If you also did comprehensive research you would realise carbohydrate as essential for more than just energy production and fat storage. Also note the human brain prefers the broken down components of carbs you would know as sugars, not the broken down fat molecules.

    Adding further argument; ask any bodybuilder, fitness model or athlete (even regular gym goers) and they will give you the same answer. A body builder tapers down the carbs towards a show to help “cut and shred” for a better defined physique. They know the hardships of carb cutting and what it does to the body let alone to the mind. But after the show you’ll find them start consuming higher levels; even directly off stage many body builder will have a high carb meal waiting.

    The key thing to point out from all this; out bodies have evolved to consume carbs from day 1. Back when we were monkey in trees and as our brain developed we required more. If you believe so whole heartedly in your “research” attempt to not eat carbs for a minimum of a week; cold turkey that is.

    If you can accomplish this you would have show self control greater than the worlds best body builders and athletes…..oh and I hope you enjoy the cravings, the headaches, the lethargy and the overall bad mood.


    • Well no, I don’t consider myself taking a beating on this one,
      I still stand by what I’ve said, but might clear up on some comments.
      No I’m not a biochemist. But I do know how to read a science paper, and know how to think for myself (and see the larger picture).
      Also remember, nutritional science is NOT a very exact science – and should always be taken with a pinch of salt – there are just too many factors.
      I make my point based on a well respected South African scientist, Prof Tim Noakes, who has extensively, and I mean extensively, researched this field. Also major research and pretty much a food revolution coming out of Sweden.
      I’ve been on a low-carb, high fat (lchf) diet for two months, aside from weight loss, all my “unhealthy markers” have improved, I’ve never felt better, physically and mentally! But I’ll say this, I am not going 0 gram carbs, but keep it below 25 – 50 grams a day – I believe it would be pretty much impossible to have 0 carbs.
      p.s. Tim has been doing it for over 2 years – never been healthier.
      When looking at the bigger picture, our carb diets of today is radically different than it was 100 years ago. It cannot even compare to what we ate as we evolved into this state. This is due to extensive GMO on foods such as crops and fruit.
      Just the amount of sugar in fruit is staggering, and certainly not normal!
      No wonder such a vast majority of the population is carb-resistant/insulin resistant.

      Greg – no need to get nasty. Also your argument doesn’t really tell me why carbs are necessary, just how it works.

      Many nutritional scientists also says that “glucose is the preferred source of energy. I disagree – our bodies don’t really want it, but burning them is an effective way of getting rid of them – provided you are not insulin resistant.

      Daniel – Ketoacidosis is a term frequently thrown around loosely. When following a healthy LCHF diet, your ketone levels never get high enough to cause ketoacidosis. It is only really a concern if you are a type 1 diabetic, they can’t produce the insulin to counteract.

      Rylan – Yes we evolved with minor amount of carbs & sugars, but it was radically different to what we get today. “The monkeys” had virtually no “sugars” as industry had not yet modified it in. Carbs were very tough (tubers) – its equivalent aren’t commercially available today. Also the crops where our starches come from, were also radically different back then and naturally much less abundant,

      But that is my humble opinion, It will take many years to get the obese, sugar addicted, heart unhealthy world to switch back to what we ate pre 1950’s. It took us 30 years to adopt a low-fat, high carb diet, and only now do we realise how unhealthy it is.

      I very much recommend all the science-types read the work from Jeff S. Volek and Stephen D. Phinney. For non-science-types and science-types please look into “The Real Meal Revolution” by Prof Tim Noakes, Sally-Ann Creed, Jonno Proudfoot, and David Grier.

      • Brandon, ADNS says:

        Like Davey has said before, everyone and every body is different. Carbs are necessary no matter how you look at it. The more you work out and exercise, essentially the more carbs you need as energy because your body has required more energy. Sugar is a very quick and short term energy source. Carbs are the bodies preferred method of energy. As Davey has said numerous times, listen to what your body tells you. Your body knows what it needs, you just have to listen. Losing weight isn’t a diet, it’s a lifestyle change, when you make that transition, a transformation begins to happen.

        Honestly, I wish I had my professor’s “short” lecture on carbs, sugars and fitness. She explained it very well. She was in the Navy nurse, after her service she became a body builder and was very fit. She’s in very good shape even today. Her focus in the medical field has always been prevention and healthy lifestyle promotion/fitness.

  6. Davey,

    I am so glad you are debunking these nutrition myths. So many people believe them and they do nothing or actually make people less health.

  7. I have tried all of those silly things and all its done ultimately is actually made me fatter because you cant live on crazy diets forever and as soon as you stop you just go back to your old ways . I have spent all my adult life going up and down on the scales and over time actually getting bigger . Now to the point were my life is uber threat from my obesity . So I have to eat a propper diet that I can actuaaly live on for the rest of my life and loose weight and be healthy

    ruan took a beating on this one! sometimes less talk is more! research it! you got it davey!

  9. christopher says:

    good advice-but controversial-i had baked beans late evening.high protein-works for me.

  10. You forgot an “is” in the first sentence if this post. Sorry, the marketing editor never stops. ๐Ÿ˜›

  11. I was always taught by my mother to eat a huge breakfast, a medium size lunch and a small dinner..and I was always skinny as a child….was she correct?
