1. Eat According to Your Metabolic TypeThe origin of this idea in the modern diet business can be traced to The Metabolic Typing Diet by William Wolcott and Trish Fahey. The general idea dates from the 1970s and perhaps even before that.
The premise is that we all have a “metabolic type” — an individual metabolism that can be manipulated by dietary choices. According to this, we all fall into three metabolic types. And how do you know your metabolic type? Usually, the practitioners of metabolic type diets ask you a range of questions about your body shape, natural food choices, energy levels and many other things. Some may charge for blood or urine tests.
No doubt, you will soon be offered a genetic test that is supposed to identify your best nutrition and training habits based on your genes, which, presumably, create your metabolic type. Already similar services are being promoted to health and fitness enthusiasts — for a fee of course.
There is no evidence that metabolic types have any validity for weight management or fitness training, including weight training. Our genes can influence how our bodies works, but genes are not faultless determinants of physical function — or behavior for that matter. Genes interact with the environment, in this case, with food and physical activity. The idea that we have a metabolic type that reacts rigidly to diet in a certain way because of a genetic component is false, or at least only partly true. Food and exercise are just as likely to change the way these genes function as genes are to demand certain foods for health, perhaps even more likely.
2. Don’t Eat Carbohydrates Because They Turn to FatThis one still persists, even after all the debunking that has been done. It is a persistent myth of misplaced emphasis that derives from the low-carb diet movement. First, some carbohydrates can be converted to fat and stored, but this is only significant if you overeat. Fructose in corn syrup and cane sugar is more likely to do this than glucose from starches, such as grains.
Second, even if some carbohydrate turns to fat, it is not permanently enshrined in some fat larder on your hips, legs, belly, arms and butt until the end of history. Mostly, you can burn it off just like you can burn off dietary fat that is eaten and stored. What matters is the total calories you consume and the energy calories you expend.
3. Eat Foods that Boost Metabolism or Decrease AppetiteWhile it is true that chemical substances, such as amphetamines, boost metabolism so that you burn more calories and this helps you with weight loss, amphetamines are powerful substances and few naturally occurring herbs or extracts have this type of effect. Or, if they do, products, such as ephedra, may not be safe for casual consumption. The FDA says ephedra is unsafe.
Other plant-derived substances touted as useful weight loss supplements are caffeine, capsaicin (chili), green tea, hoodia and many others sold as natural remedies. Some, such as hoodia, are supposed to be appetite suppressants.
The main issue with these weight loss solutions is that they aren’t solutions. Some may provide a small benefit, but mostly they cost you extra money and distract from the main game, which is getting your food intake and exercise plan working for you over the long term. There’s no harm in consuming coffee, chili and green tea as part of a normal diet. Spending big on supplements or exotic herbs for this purpose is bound to disappoint you if you don’t address the major factors in weight management.
4. Negative Calorie Foods Can Help You Lose WeightThis one is only for the very naïve. The idea that certain foods use more energy in digestion than they contain in calories is not to be believed, especially when lists of such foods includes fruits that contain significant calories in natural sugars.
If you eat a diet of green leafy vegetables and fruit, you probably will lose weight, but that’s because, overall, you will have reduced your calorie intake substantially. Try the Calorie-Count database to see how many calories are in various foods.Read the full article here
