Target weight is to be around 75 - 80 kg by December next year and yeah I'm aware of a lot of things in terms of age and foods I'm just wondering weather the recommended intake of calories is actually accurate
You don't say anything about your target weight. I assume you're trying to gain weight, but tell us exactly what you're trying to accomplish. I'd like to also say that eating a lot to gain weight is fine with the amount of working out you're doing, but keep in mind a lot of the food you're eating isn't very good for you. Health is still the most important thing. I'd also say be careful at such a young age when you're body is still developing to overdo both the eating and the exercise. Do you have a nutrition and fitness coach?
I am 16, coming on 17. Height - 180cm. Weight - 66.5KG or 10 1/2 stone. My training sessions are high intensity with a small increase in weight every week or two. My routine is Monday - arms 1hr. Tuesday - abs - anywhere from 1hr or more (daily an work but tuesday is focused mainly on these muscles). Wednesday - chest 1hr. Thursday - 1hr legs. Friday - arms. Saturday - shoulders and back. Sunday rest. Breakfast I have around 4 wheatabix blocks, followed by a bowl of porridge and 2 scrambled eggs, 2 pieces of toast. Lunch I have a bacon sand which with eggs a banana and apple. Throughout the day I'll eat mainly fruit variations in the house with little intake of chocolate or anything of that kind. Depending on the day I will have fish with sweatcorn and sweat patatoes.
