Low Carb Diets

low-carb-dietDue to extensive publicity, low carb diets have become increasingly popular.

However there is considerable ambiguity over exactly what is low carbohydrate. Many companies have seen low carb popularity as a brand to be exploited.

Low Carb – A Definition

All food is made up of three primary macro nutrients – carbohydrates (or sugars), proteins, and fats. Low carb implies that the percentage of carbohydrate (by calorie) is low – but lower than what?

  • High Carb 50-70% (USDA Food Pyramid)
  • Moderate Carb 40-50%
  • Low Carb 25-39%
  • Very Low Carb 0-25%

However it is common to find that any diet less than 50-60% carb ratio is called a low carb diet.

Depending on one’s sensitivity to carbohydrates, a moderate carb ratio may be better than a high carb ratio.

By definition, the lower the carb ratio – the higher the fat and protein ratio. Generally speaking a low carb diet will also tend to be a high protein diet.

Popular Low Carb Diets

The following diets are generally all ‘lumped’ together under the definition of ‘low-carb’. However they actually are made up of little or no carbs – to some that are moderate carb.

The Low Carb Industry

The surging popularity of low carb diets caused an entire food industry to appear seemingly overnight. An entire line of foods now bear the catchy name “low carb”.

What’s unfortunate is that a lot of these foods are very processed, and are not rich in nutritional quality. Clever marketing has come to the fore, with terms like “Smart Carbs” and “Net Carbs” appearing on many products.

The craze began to decline towards the end of 2004 but continues to be popular.

It Doesn’t Work For Everyone

Some people respond very well to low carb eating and lose weight quickly. However, some do not. It really depends on your genetic make-up and how you process carbs based on it.

A low carb diet is just one of the many viable methods a person can use to lose weight or stay slim.

    I just started my diet. I want to lose 55-60 pounds by Christmas. At my doctors urging I need to do this. So am I right in lowering carb intake, like eating salads, green, veggies and some fruits? Am I starting at the right place????

    • ted

      Hey Glenn, yes but you want to also increase your protein intake because this will keep you from feeling too hungry which could lead to slip ups.. Best of luck!

    Oh, and you dont’ have to go very low carb to achieve good results. Moderate carb works well.

    Trish, I’m periomenopausal, post hysterectomy, and I’ve been using low carb & exercise since Sep 08. I’ve been successful with getting 60lbs off and keeping it off. Never felt better. And didn’t know the menopausal symptoms had me feeling sooo bad!

    Do low carb diets work w post-mnopausal women? seems more difficult now to lose weight even with increased exercise

    Low carb diets are tough, especially south beach and others that require you to cut out fruits, breads, desserts, chips and other snacks. I think the best diets are ones with weight training built in to help your body burn more calories instead of just cutting carbs and calories. I use low carb chocolate to help curb my cravings and stay on my diet and meal plans.

    Low carb diets work the best, and Atkins is a pretty good standard.

    The primary cause of fat gain is Insulin, which is always triggered by carbohydrate intake. Insulin tells the body to store energy, in muscles and – more commonly – in fat tissue.

    >Holmes, I can understand you would think your diet works the best, sicne if it gave me results I would approve of it. However it doesn’t sound particularly healthy, and I’m guessing that with a low carb diet you would need half of the exercise you did (which I’m assuming was boring low intensity cardio?).

    Low carb means that you will be constantly burning fat – stored or from diet – for energy, this means that you would still lose weight even if no exercise was involved.

    And Green Vegetables are gods in this diet, since you can scoff as many as you want.

    > elvis: is this for real ? why should I restrict energy food ?

    Because what do you think your body burns for energy if you stop eating sugar? Duh.

    Sadly, this doesn’t work with other diet plans, so everyone assumes you must be weak, miserable, and starving on low carb, too. When actually, you’re full and bursting with energy and health for the very first time in your life.

    Read the Atkins book. It starts at 20g and goes up to 200g or so. The rules are very specific.
    Salads and ranch dressing are fine. Baked potatoes aren’t. Everything you used to put ON the baked potatoes? Encouraged. Yum.
