Will Low-Carb Diets Help You Lose Weight
With so many different diets and nutrition programs available these days, it can be difficult to figure out which strategy you should adopt to get the results that you want. Some diets claim that carbs are deadly, whilst others advocate a complete avoidance of all dairy products. The fact is that the majority of these diets promote extreme methods that are not sustainable in the long run. There are no quick fixes or magic pills to guarantee you results, but there certainly are nutritional approaches that will help to maximize your results. The focus here is on health and making healthy food choices. But first, lets have a look at some of the most popular diets and why they don’t make the best choice if sustainable results are what you are after.
Extremely low carb diets like the Atkins diet do seem to work well in the short term, but because they advocate a complete removal of carbohydrates from the diet, sustainability is an issue. It has been debated that any diet that completely removes one of the three macronutrients (carbohydrate, fat or protein) should be approached with caution, and the fact that the Atkins diet comes with a warning that those following it may experience weakness, fatigue and leg cramps speaks volumes. Moreover, very low carbohydrate, or ‘ketogenic’ diets have been shown to be inferior to diets that contain a more balanced ratio of carbohydrates, fats and proteins. A large study was performed comparing ketogenic diets (high protein and high fat, zero carb diets) with non-ketogenic, moderately low carbohydrate diets. The ketogenic diet was associated with an increase in harmful LDL cholesterol.
Another very popular diet, at least was for a the minute there, is the Paleo diet. If you can’t go a day without eating meat, then you may think that this is the perfect diet for you. The diet is based on that of our Palaeolithic ancestors, and focuses on lean meats, seafood, non-starchy vegetables and fruit. Dairy products, grains, legumes, and all other processed foods are to be strictly avoided.
Sustainability is therefore an issue, as are certain micronutrient deficiencies. With all dairy products removed from the diet, it can be difficult to consume enough calcium when following a Paleo lifestyle. Vitamin B6 – found in grains, might also be an issue for those on the diet, who will struggle to meet their requirement for this micronutrient through the consumption of lean protein alone.
The diet that is hard to ignore right now, it is also very controversial. A keto diet is high in fat, a normal amount of protein and low in carbohydrate, used as medicine to treat hard-to-control epilepsy in children. It isn't new, the ketogenic diet became popular as a therapy for epilepsy in the 1920s and 30s. The diet forces the body to burn fats rather than carbohydrates. Such low-carbohydrate diets can produce positive results in some individuals, especially for people with insulin resistance.
Keto diet may cause fatigue at the beginning, but a well-formulated ketogenic diet have not shown major safety concerns for a majority of people. From the evidence we have so far, a ketogenic diet may be effective for the treatment of obesity and type 2 diabetes. A ketogenic diet is also very promising, for other conditions associated with metabolic dysfunction, such as type 1 diabetes.
The problem with extreme nutritional approaches, like those highlighted above, is that they hard to maintain for long period of time. Many people will struggle to follow the rigid structure of these diets, and will quickly fall back into their old habits. Small but sustainable changes are a better place to start. Focus on consuming plenty of whole foods, which will improve satiety and are naturally rich in vitamins and minerals. Eat lots of fruit and vegetables, and try to limit processed junk food as much as possible. Unless you are lactose intolerant, there is no good reason to avoid dairy. It is rich in calcium and other micronutrients that help to support good health. If you are looking to maximize your results, then there are a number of other factors that you will need to consider, like nutrient timing and your macronutrient ratios. However, these more advanced nutritional strategies should be put in place only once you have the basics covered. Get this right and you will set yourself up for long-term success. References: 1.)
