Before you apply, you should be clear about what you want from your credit card. All credit cards give you flexibility to manage your cash flow over a month but some cards have other benefits on top of this. Customers with a good credit history are more likely to have access to cards with these extra benefits.
When you switch to a low carbohydrate diet, the drop in fruit, vegetables, legume and grain consumption can significantly decrease fiber intake and result in inadequate phytonutrient, antioxidant, vitamin C and potassium intake.
Note on Saturated Fats and Low-Carb Diets. The Atkins Diet, LCHF, and most other low-carb approaches don't emphasize reducing saturated fats as long as carbs are kept low. They point to the lack of evidence that reducing saturated fats to extremely low levels is helpful in terms of risk reduction for most people.
