Starting a keto diet comes with its share of challenges.

Be prepared to cut back on carbs, track your macros, and go through the so-calledketo flu.

These changes may seem overwhelming, but you’re free to take one step at a time.

Bok choy, celery, zucchini, radishes, and kale are low in carbs, too.

Other veggies, such as corn, onion, and beans, should only be consumed in small amounts.

These symptoms are perfectly normal and should subside within two weeks.

Therefore, it’s normal to experience a decline in physical performance when you switch to a low-carb diet.

Going keto can also affect muscle growth and exercise performance at higher intensities (perNutrients).

All in all, starting a keto diet takes some planning and determination.

Plus, there is a risk of gaining the weight back when you return to normal eating.
