Do low/no carb diets make you lose more fat? No, they don't. Not in the long term at least. Studies have shown that while low carbers lose more weight in the initial outset of a diet, (due mainly to water loss) over a year when compared with a "balanced diet" (providing carbohydrate) there was no difference in weight loss. The "balanced" group actually lost a little more weight but it was not statistically significant. In addition, blood glucose and insulin levels correspond positively with leptin, a hormone in your body that has a very large role in weight maintenance. What this means is that basically low carbohydrate diets mimic starvation on many levels, not something you want. Thats not to say that low-carb diets have no use, they certainly do, there's just no "metabolic advantage" to them.
You have to do tons of cardio to get shredded: No, you don't. You have to create a caloric deficit. I'll probably say this a million times but you must create a caloric deficit to lose bodyfat. How much of total body weight you lose as bodyfat will depend on your exercise regimen, diet, genetics, and supplementation. So instead of running you could simply eat less, though a combination of the two would be ideal. Of note, High Intensity Interval training (will be discussed in the future) may actually increase your bodies capacity to burn fat by upregulation of certain enzymes.
(Women) Lifting weights will make me look bulky (often accompanied by some flexing): Lifting weights is not going to make you look bulky unless you
- Are in a caloric surplus
- Using steroids, insulin, GH etc.
The fact is, you don't have the sort of hormonal system needed to make you very "bulky". Resistance training (weight lifting) confers a lot of benefits including fuel partitioning (more calories to muscle than fat), Calorie burn (as much as 9 cal/minute burnt), Better control of food portions, increased mental health, protection against wasting diseases etc etc. Lift, you'll thank me for it.
Whats the best drug/supplement to get me ripped in 2 days? That was a bit of an exaggeration but people ask me all the time, what can I take to accomplish my goals in (an absurdly short amount of time). Here it comes people, get ready for it. There isn't one. No magic bullet, no pot of gold at the end of the rainbow, no santa claus. Now this is not to say that there aren't some nifty supplements/drugs for fat loss/recomposition because there are, I'll write more on those soon. The issue is people are going to rely mainly on this supplements, they think that it is going to be the main pulling horse on their plow of fat loss. It's not, and even if it was, its not sustainable. There is, for example, a very potent fat burning drug that many of you have probably never heard of (and I won't name it yet simply because I don't want you killing yourself before I write a full article on it) that causes losses of 2/3 lb to 1 lb of fat loss per day. You can't stay on this drug forever though, you build a tolerance and on top of that, it can literally cook you inside your skin.
Moral of the story: Drugs/supplements can help, but you cannot rely on them alone to reach and maintain your fatloss goals.
Eating before bed will make you fat: Again, no it won't. If you read the little bit above on cardio, it's the same deal. Eating something that puts you over maintenance calories combined will make you gain weight.
You have to eat 6 times a day to get your metabolism revved up. NO NO NO. This misconception stems from the thermic effect of feeding, i.e the amount of calories your body burns processing the food. The effects is different for each macronutrient but lets just say its 10%. With a 2000 calorie diet this makes 200 calories a day burnt processing the food, do you think it matters whether those 2000 calories were consumed in 6 meals or two? No, not really.

Localized fat loss: Losing fat just on your hips or thighs without supplement/drug intervention is not possible. Spot reduction does seem to have some real world applicability with certain drugs/supplements but I should note.
- You already have to be lean (<15%)
- You need to be in a calorie deficit
- The effects are marginal
Closing: These are obviously not all the myths/statements in the fitness community, but I think some of the more prevalent ones. If you would like me to cover one in more depth or think I missed a big one I will be happy to go into it. 'Til next time.
