I started the keto diet a little over a week ago. Somehow I've lost 6 pounds in the first week alone. I'm not even sure how that is possible, but the scale doesn't lie. Basically I keep to 30g of carbs or less a day. You are allowed under 50g, but most suggest the lower amount so you have wiggle room for screw ups. To supplement this I've also eliminated sugar almost completely from my diet. So 3g or less a day. This basically covers the multitude of seasonings that generally contain less than 1g of sugar. I also make sure to stay at 2,000 calories or less a day. At the end of the day calories in, calories out. I started keto so I could retrain my body to burn fat. On this diet you can pretty much eat fatty stuff, and it is encouraged. (like fatty cuts of meat). Fat keeps you full. This is why other diets never worked for me I guess. The first three days my body was definitely not happy. Stomach pains and... uh... frequent trips to the bathroom (might account for the extra weight loss... you know... water weight). All good now though.
