Low carbohydrate diets, from keto and Atkins to Primal and Paleo, are enjoying a moment in the spotlight. Carbohydrates are one of the three macronutrients, the other two being protein and dietary fat.
Protein is highly thermogenic, meaning your body actually has to work harder to process and digest it than it does with carbs.
The verdict"The theory of the alkaline diet is that eating certain foods can help maintain the body's ideal pH balance (acidity levels) to improve overall health. In many cases, a low-carb diet causes 2-3 times more weight loss as the standard low-fat diet that we’re still being told to follow (1, 2).
In fact, the studies show that these diets cause major improvements in many important risk factors (3). A high percentage of the fat lost on a low carb diet comes from the belly area and the liver. Unfortunately, this is not fully known, and chances are that it is multifactorial – as in, there are many different reasons why these diets are so effective (11).
In this article, I take look at some of the most convincing explanations for the effectiveness of low carb diets.
It is actually well established that low-carb diets lead to drastic and almost immediate reductions in insulin levels (12, 13). However, I’d like to point out that many respected obesity researchers do not believe this to be true, and do not think the carbohydrate-insulin hypothesis of obesity is supported by the evidence.
Glycogen: The body stores carbs in the form of glycogen, which binds water in the muscles and liver. This does not happen to nearly the same extent on a higher carb diet, even if calories are reduced significantly.
Even though some people use this as an argument against low-carb diets, reduced water weight should be considered an advantage. Anyway, despite claims to the contrary, this is far from being the main weight loss advantage of low-carb diets.
So, part of the weight loss advantage of low-carb diets is explained by reductions in water weight, but there is still a major fat loss advantage as well.
Bottom Line: When people go low-carb, they lose significant amounts of excess water from their bodies. In most studies where low carb and low fat diets are compared, the low carb groups end up eating much more protein. This is because people replace many low-protein foods (grains, sugars) with higher protein foods like meat, fish and eggs.
Many nutrition experts believe that the high protein content of low-carb diets is the main reason for their effectiveness. Although this is controversial, many experts do believe that low carb diets have a metabolic advantage.
In other words, that low carb diets increase your energy expenditure, and that people lose more weight than can be explained by reduced calorie intake alone.

A study conducted in 2012 found that a very low carb diet increased energy expenditure compared to a low fat diet, during a period of weight maintenance (21). However, another study has suggested that it may be the high protein (but not low carb) part of the diet that causes the increase in calories burned (22).
On a very low carb, ketogenic diet, when carb intake is kept extremely low, a lot of protein is being transformed into glucose in the beginning, a process called gluconeogenesis (23).
Bottom Line: Low-carb diets appear to have a metabolic advantage, but most of it is caused by the increased protein intake. Many of these foods are also highly rewarding, and the reward value of foods can impact how many calories we end up eating (26). Bottom Line: Low carb diets exclude many foods that are highly rewarding and extremely fattening.
Probably the single biggest explanation for the weight loss effects of low carb diets, is their powerful effects on appetite. It is well established that when people go low carb, their appetite goes down and they start eating fewer calories automatically (27).
In fact, studies that compare low carb and low fat diets usually restrict calories in the low-fat groups, while the low-carb groups are allowed to eat until fullness (28). Many people who go on a ketogenic diet feel that they only need to eat 1 or 2 meals per day.
There is also some evidence that low carb diets can have beneficial effects on appetite regulating hormones like leptin and ghrelin (30). Bottom Line: Low carb diets lead to an automatic reduction in calorie intake, so that people eat fewer calories without having to think about it. Even though low carb diets are very effective in the short-term, the long-term results are not that great. Most studies that last for 1-2 years show that the difference between the low-carb and low-fat groups mostly disappears.
There are many possible explanations for this, but the most plausible one is that people tend to abandon the diet over time, and start gaining the weight back.
This is not specific to low carb diets, and is a well known problem in most long-term weight loss studies. Some people refuse to accept that low carb diets can work, and that people can eat as much as they want, because that must violate the calories in, calories out model.
However, when you understand the mechanisms behind low carb diets, you can see that the CICO model is not being violated, and the laws of thermodynamics still hold. They boost your metabolism (increasing calories out) and lower your appetite (reducing calories in), leading to automatic calorie restriction. Calories still count, it’s just that low carb diets automate the process and help prevent the biggest side effect of conscious calorie restriction, which is hunger. As the name suggests, carbohydrates bind with water (hydrates), so for every gram of the macronutrient carbohydrate we eat, we also take on around 4g water. To lose body fat using a lower carbohydrate approach takes a slower and more long term nutritional overhaul (like any sustainable diet).

Both of these make you feel nice and full, giving a sense of satisfaction which lasts longer than simple carbohydrates. Although both macronutrients have the same calorie count (4 kcalories per gram for both carbs and protein), protein takes more effort for your body to digest, process and use. Some people are very sensitive to carbohydrates, and find that even the healthiest and most natural carbs lead to cravings not unlike classic sugar cravings.
It's not wise nor necessary to cut out all carbs, unless you really are going on a strategic ketogenic diet. The plan recommends three snacks a day from an extensive list, including crisps and chocolate, two meal replacement shakes or bars and one regular meal, taken from a list of recipes on the Slim-Fast website.You can stay on the diet for as long as you want, depending on your weight loss goal. We’re concerned that this diet promises such a large weight loss, up to 13lb, in the first two weeks. High insulin levels contribute to fat storage, and low insulin levels facilitate fat burning. When carb intake goes down, glycogen levels in the body go down, and the water follows along. In the beginning of a very low carb, ketogenic diet, some calories are wasted when glucose is produced.
A lot of foods have a carbohydrate content, such as vegetables, fruits, seasonings, chocolate, all types of sugar (even natural ones), nuts and seeds. Carbohydrates also keep our glycogen stores (in muscle tissue and in our livers) topped up. Here's why low carb could lead to better body composition and less body fat in the long term. If you want to minimise your carb intake, start by cutting out the highly-processed, manmade stuff (bread, pastries, cakes and cookies, crackers, cereals).
Once reached, you’re advised to have one meal replacement shake a day, up to two low-fat snacks and two healthy meals. If you are interested in lowering or controlling the amount of carbs you eat, get used to reading food labels and using some sort of recording tool (like an app) to record total carbohydrates in everything you eat. Reduce carbs, and not only will your glycogen stores become depleted, but you will literally lose water weight.
This is why people can often drop significant amounts of weight, and look smaller, from just a few days of dropping their carbohydrate intake.
Carbs are off limits except for a small amount of oat bran.The next three phases of the plan see the gradual introduction of some fruit, veg and carbs, and eventually all foods.
