Though the ketogenic diet (KD) has gained a lot of attention recently and may seem like a passing fad, it’s actually been around since the early 1920s. The KD is a high-fat, very-low-carb, moderate-protein diet that puts your body into a state of nutritional “ketosis” – this means your body relies almost exclusively on burning fat, instead of sugar, for energy.
Historically, the KD has been used to treat patients who had epilepsy. It’s also been shown to improve cognitive and motor function and reduce brain inflammation, and research has shown the KD to significantly reduce symptoms of mental disorders such as depression and schizophrenia.
The paleo diet is one of the oldest on Earth. This diet is all about eating real, unprocessed foods in their most natural forms, the way cavemen and our hunter-gatherer ancestors most likely did. This ancestral-style diet is made up of unprocessed lean meats, fish, eggs, fresh vegetables and fruits, nuts and seeds, and fresh and dried herbs and spices—basically, any food you could get by hunting or foraging.
Following a paleo diet means cutting out processed, refined foods, which are all-too-prevalent in the typical Western-style diet. This alone can help work wonders for managing weight and reducing the risk of chronic disease.
Simply put, the pillars of the paleo diet plan include increasing protein, fiber, fruit, vegetable, potassium, vitamin, mineral, and antioxidant intake while improving fat intake and lowering carbohydrate intake, glycemic load, and sodium intake. Paleo also involves eliminating processed foods, cereal grains, trans fats, legumes, refined vegetable/seed oils, added sugars, soft drinks, juice, sweets, and dairy.
It’s exactly what it sounds like–going periods of time without eating. Voluntary fasting (very different from starvation) has been practiced around the world since the beginning of time. Though there are different types of fasting, Time-Restricted Feeding (TRF) is the most popular.
This means you only eat during a certain period of time, usually lasting around 8 hours or less. This may sound unhealthy since many dietitians have recommended eating small meals every 2-3 hours. Others, though, believe fasting helps reset your body and boosts your metabolism, aids in weight loss, and improves heart health.
