If you decide to lose weight anyhow, remember that there are no short cuts or instant solutions. Ultra Fast Keto Boost Fad diets and fasting are not at all recommended for teen girls weight loss. Fasting deprives a growing body of much needed food for energy and the body turns on its own tissues. Digestive juices produced by the stomach turn into harmful acids.
Carefully controlling calorie intake to match your burn rate is considered best practice for losing weight. Dietitians or medical practitioners have the required techniques and knowledge to calculate Lean Body Mass (bare weight of your bones, muscles, organs and tissues), Basal Metabolic rate (the rate at which your body burn calories while at rest), etc and calculate calorie intake for teen girls weight loss.
