An LCHF lifestyle: Eat real, wholesome food only.
Avoid processed junk food and always try to choose organic, free range, grass-fed meat, eggs and dairy if possible. Avoid sugars completely, however xylitol, erythritol and stevia are sweet substitutes you can use but do not opt for artificial sweeteners as they contain all sorts of nasty chemicals and preservatives in. Cut out carbohydrate from your diet especially the high carbs which include bread, pasta, rice, breakfast cereals, pastries, cakes etc. Your body will get enough carbs from the vegetables that you eat and green leafy vegetables are the best.
