The Atkins diet was developed and popularized by Dr. Robert Atkins, an American heart doctor, in his 1972 book.
It is a ketogenic diet that believes health and weight loss is best achieved by a high-protein, low-carbohydrate diet. The idea is that when our body is starved of sugars (carbs), it enters a state of ketosis which helps burn unwanted fat.
The diet itself comes in four phases. Phase 1 is called Induction and it’s the strictest phase. It lasts from 2 weeks to several months. It’s when most of the weight loss should be achieved. After successfully completing Phase 1, people progress to the remaining phases.
In Phase 1, there is strict avoidance of most carbs, including all fruit and starchy vegetables, grains or refined carbs. It also restricts nuts and seeds, legumes, dairy and caffeine. It allows for low carbohydrate butter, cream and cheese.
The good news is that there’s no calorie restrictions of allowed foods.
