The Atkins Diet
Who? Kim Kardashian, Renée Zellweger and Jennifer Aniston.
What? The original low-carb meal plan, the Atkins Diet is a favourite among celebrities and pro athletes alike. We’re sure you all know the deal, but for those who need a little recap, it’s all about a low-carb, high-fat diet that means you don’t fill up on empty calories. So a double-cheeseburger is totally fine, just as long as you don’t eat the bun.
Why? Restricting carbs to such small amounts is said to put the body into a fat-burning, ketogenic state to spark rapid weight loss as your body feeds on stores of fat for energy.
The Food Combine lean proteins like fish and chicken with healthy fats, including fresh vegetables and low-GI fruits.
The Cons There are heaps of documented problems with the Atkins Diet, not confined to the fact that it restricts your body to an amount of carbs way lower than your body needs to function, as well as icky side effects including bad breath and constipation.
The Paleo Diet
Who? Jessica Biel, Megan Fox and Uma Thurman.
What? Also known as the Caveman Diet or Stone Age Diet, the Paleo Diet pays tribute to our hunting and gathering ancestors, eating only what they would have done back in the day before modern food-production methods look over our lives. As such, you’re guaranteed a much healthier lifestyle, free from processed foods and drinks.
Why? Eating this way is said to lower the body’s glycaemic load, contribute to a healthy ratio of saturated-to-unsaturated fatty acids and increase the body’s consumption of vitamins and nutrients.
The Food Think lots of fish, grass-fed meat, fruit, veggies, mushrooms, nuts and roots, most dairy products are banned, as are refined salt, sugar, oils and processed food.
The Cons While there are fewer problems with this diet than others, the main issue people have is that your shopping list is super strict, so it’s unlikely you’ll be able to turn this into a lifestyle change.
The Alkaline Diet
Who? Gwyneth Paltrow, Kirsten Dunst and Victoria Beckham.
What? One of the biggest breakout diets as of late, the Honestly Healthy Alkaline Diet involves eating mainly alkaline foods in order to keep the body’s pH between 7.35 and 7.45. Modern Western diets can make our body way too acidic, so it’s all about balancing it out.
Why? It promises to improve energy levels and memory as well as help prevent headaches, bloating, heart disease, muscle pain and insomnia.
The Food Fresh fruit, vegetables, roots, nuts and most veg including kale, spinach, asparagus and cauliflower are all alkaline. Surprisingly, fish and shellfish are acidic, so they’re out.
The Cons The research is limited, with many health professionals dismissing the diet as completely unnecessary, while it takes a lot of research, too – for example, lemons and apple cider vinegar, which are acidic in nature, are listed as alkaline due to the way they are metabolised in the body. So you’ll need to know your stuff.
The Blood-Type Diet
Who? Liz Hurley, Miranda Kerr and Cheryl Fernandez-Versini.
What? Dubbed the ‘Eat Right 4 Your Type plan,’ this diet is based on the principal that different blood types react in different ways to certain foods. By following the plan, you can make informed choices about what you should be eating to complement your body. Apparently, most diets fail because they don’t match the way our bodies work.
Why? There are four basic blood types: O, A, B and AB, and it’s best to adapt according to yours if you want to lose weight effectively.
The Food It’s totally dependent on your blood type, but for some examples, Type O should focus on high-protein foods; Type A should go meat-free; Type B need to avoid corn, wheat, lentils and tomatoes; and Type AB should eat a diet high in tofu, seafood, dairy and green veg.
The Cons As well as being complicated and time-consuming, cutting out entire food groups can lead to serious nutrient deficiencies. It could therefore be a problem for blood types A and O
