That being said, there are countries around the world, like India, where a plant-based diet is the norm. Typically this shift occurs for one of three reasons: In recent years the number of people shifting to a plant-based diet has dramatically increased, particularly in the United States and Europe. The Paleo diet is well known across Western Europe, North America and Australasia, however, many followers of the diet find it difficult to stick to when travelling or eating out due to its restrictive nature. After all, if they wanted to eat then they had to hunt and gather, exerting much more energy than the sedentary lives we lead today.ĭespite this, the Paleo diet has been proven to aid weight loss, as well as provide other benefits for those with digestive or inflammatory issues. Our ancestors were also much more physically active than we are today. Now, the logic behind the Paleo diet does have its flaws since the foods that would have been available to our ancestors would have varied considerably depending on where in the world they resided. Restrictions on the Paleo diet typically limit or omit the intake of dairy products, cereals, starchy vegetables, and sugar. Instead focusing on lean proteins, lots of fruit and vegetables, and only consuming healthy fats in the form of nuts, seeds and natural oils. ![]() Voegtlin pioneered the concept that we should learn from our ancestors and revert to a more natural way of eating, removing sugar, salt and processed foods from our diet. The core principles of these diets are the same, whilst they vary in terms of restrictiveness and the foods that are allowed to be ingested as part of the overall diet. Walter L Voegtlin, introduced the idea of the Paleolithic diet in his book, The Stone Age Diet, paving the way for similar diets such as the Caveman diet, the Hunter-Gatherer diet, and the most well-known Paleo diet. It also requires followers to take a daily supplement of oat bran, and may require additional supplements due to the limited fruits and vegetables that can be consumed.ĭespite this, the Dukan diet maintains popularity in France and mainland Europe, but has also experienced reach outside of Europe with the official diet book being translated into 14 languages, selling over eight million copies around the world. ![]() Now, the Dukan diet has been criticised for not being nutritionally balanced due to its highly restrictive nature. ![]() The two subsequent stages (consolidation and stabilisation phases) are then designed to stabilise the individual’s weight and solidify healthy eating habits for the long-term. The second phase, called the cruise phase, slowly introduces carbs in the form of 28 approved vegetables, but lasts as long as it takes the dieter to reach their target weight. How long someone follows the diet for depends on their starting weight, fitness levels, and desired results.įor example, the first phase, or the attack phase, lasts between five to ten days where dieters have 72 high-protein foods to choose from, but carbs are completely banned. ![]() We will take a look at four popular diets, Dukan, Paleo, plant-based and Keto, as well as alternatives to dieting which are also increasing in popularity around the world, including surgery and the use of supplements. This is particularly true of developing countries where exposure to weight loss diets is yet to reach the overexposed levels experienced in the developing world. As you’ll see, these diets may take years to become known and accepted in certain regions, whilst popularity declines elsewhere in the world. In recent years, however, there has also been a rise in popularity for weight loss diets across the globe, some of which we’ll focus on in this article. Despite being quite common in developed countries, like the US, we are seeing a rise in obesity in developing countries due to rising disposable incomes in the middle classes and increased Westernisation when it comes to food. Ĭountries particularly impacted by increasingly overweight populations include the United States, China, and India. According to data from the World Health Organization, published in 2021, as many as 2.8 million people die every year due to obesity, whilst 115 million individuals from the developing world suffer from obesity-related health conditions.
