Hi welcome back!!
Low carb diets are back in the news again so it seeems timely to revisit them. Let’s be clear – cutting out ANY macronutrient group is a mistake, BUT certainly sub-types of macronutrients should be curtailed for health benefits and fat loss.
There is no doubt & lots of studies that prove that Low Carb diets result in weight loss (not just fat – more on this later) for those who follow the protocols correctly. The protocol, roughly speaking is eating less than 100 grams of carbs per day over an extended period of time. (in the Atkins phasing in period it is down to 20 or 30 grams)
The instinctive knee jerk from the popular press and most nutritionists is that low carb diets are bad for your health. A lot of these people who lost weight on these older style low carb diets became, in effect, skinnier fat people.
This is because shedding carbs usually involves water loss and if too severe for too long can also result in muscle being broken down for fuel in preference to fat – so you lose weight but end up percentage-wise just as fat as before. But with less muscle, a slower metabolism and rebound weight that is incredible to endure!!
The howls of outrage about the evils of low carb are based upon outmoded, and frankly decades old types of low carb diets. Originally Atkins cut out all types of carbs, but as the years went by they then developed the idea of ‘net carbs’ where eating fibre rich carbs was okay as these were nutritionally dense but calorie & more importantly sugar poor.
So the idea of low carb meaning no carbs at all is not only out of date and old fashioned but it is plain wrong. Likewise the idea that low carb means that you must eat loads of fat. The best low carb diets do NOT advocate an open slather approach to fat in your diet – they advocate eating lean protein wherever possible.
These days low carb means cutting out processed carbs, and eating your fill of fresh vegetables and some fruit. Eating low carb in this fashion supplies all of the nutrients that the nutritionists are concerned about you missing out when you eat ‘traditional’ low carb.
But there has been further research papers published recently that shows that folk on low carb diets did not lose a lot of weight.
Let’s talk weight first – the most beneficial thing for your health, if overweight, is to lose fat. Losing weight is a misnomer and a dangerous one. Many diets cause you to lose weight through water and muscle loss. The infamous detox & some shake only diets do this which is why the rebound weight gain is so high. Unfortunately when this happens you ahave less muscle, your metabolism has slowed and you find it harder to lose fat. And so it goes.
Upon examination however it turns out that the folk who ate low carb had one or more of the following failings:
1) They cut carbs but kept their alcohol consumption at their regular level. Alcohol, as we’ve noted in other posts, kills fat loss.
2) They didn’t eat lean meat & protein but went the high fat route. Again not the way to lose weight nevermind about fat.
3) For a number of people dropping back to 100 grams of carbs was not really going low carb, just dropping their own carb intake lower. 100 grams of carbs is considered moderate in most studies.
4) At the other end were the folk who declared all carbs bad and so deprived their bodies of not only the preferential fuel source but also a lot of needed nutrients.
So what is the right way to use a low carb diet?
Well firstly you should view it as a lower processed carb diet – not a low carb one.
When followed properly, a lower processed carb diet sees you eat more lean protein to supply your body the nutrients to build new lean muscle. The amino acids from protein sources can also be used to provide your body with some of its energy needs.
Couple this with a moderate intake of healthy fats, a lowered alcohol intake and you have a solid basis to lose fat.
As you’ve heard me say before – carbs are not the enemy but we tend to eat not only too many carbs but too many of the wrong types of carbs. In the main eating high GI, highly processed carbs leads to fat gain.
So doing something as simple as replacing half of your current processed carb intake with low GI un- or lightly processed carbs may very well help you to begin to lose fat.
This is why a lower processed carb diet may be beneficial to you is because it forces you to stop eating all the processed simple carbs that usually contain a lot of calories but not a lot of nutrients. And we know that a lack of needed nutrients leads to cravings and increased hunger which leads to more eating which leads to…
By eating a greatly reduced amount of processed carbs you also re-train your body to adjust the way it utilises the calories. Add to this the increase in lean protein with good fats and your body will become more efficient at functioning with fewer sugars. Also by lowering processed carbs it becomes easier to use up the stored carbs and fat you are carrying around.
Following a low processed carb diet is an effective way to lose fat, to learn to eat in a healthier manner by choosing better foods and training your body to use the nutrients differently and more efficiently.
The original low carb approach had a lot to recommend it but the true value lies in a low processed carbs diet. This is the one that works.
Have you followed a true low carb diet before? Were you successful with it?
