keto diet -: In my opinion, however, the burning question when it comes to low-carb foods is: are we getting away from the real point of the low-carb diet? Processed foods are what got us into the obesity epidemic that we're in today.So how can you lose the weight and keep it off without putting your body at harm? You need to follow a healthy diet plan that includes all your food groups. Eat a diet that is low in fat and calories. You are probably thinking that you will be starving and not have your favorite foods, well this is not true.
