Generally, the Atkins Diet embraces a high amount of protein and fat, and basically cut out carbohydrates. Atkins 40 is an updated take on the well-known meal plan, which also embraces low-carb meals to lose weight.

When starting the Atkins 40 plan, you are allotted 40 grams of Net Carbs for the whole day. The diet consists of four overall stages and gradual increased carb intake is allotted for each.

Those following the Atkins 40 diet also avoid and limit added sugar and refined carbs, like white flour, because these foods are not very nutritious, according to Atkins.

People on this meal plan will need to choose foods from the acceptable food list. On Atkins 40, dieters eat a ton of vegetables (actually more than recommended by the USDA), meat, fish, poultry, plant-based proteins, olive oil, avocado, nuts, Greek yogurt, cheese, fruits, and whole grains.

Alcoholic spirits such as Scotch, rye, vodka, and gin are accepted, but mixers containing sugars — like juice, tonic water, and non-diet soda — are not permitted on this regimen.

“Atkins is founded on the principles of optimal protein intake, adequate healthy fat intake, and low carbohydrate consumption,” Colette Heimowitz, vice president of nutrition and education at Atkins, explained to StyleCaster.
