Right. First off, 6 hours a day in the gym is not necessary. Keep it to 2 hours maximum.
Here's a load of help for your diet and training:
Go to this link, fill out the information about yourself in order to find out you maintainence calories:
https://www.bodybuilding.com/fun/macronutcal.htmBy working out your maintenance calories you will be able to find out how many calories you need to take in daily to ensure you achieve your long term goals.
So, now you know your maintainence calories, take this number and subtract 250 to 500 away from it to leave yourself in a calorie deficit. This way, you are reducing your necessary calories to maintain your body weight to a level which will reduce your body weight.
Download the app: MyFitnessPal. This will be your best friend when it comes to tracking food. And trust me, this is really important.
So, you have your daily calorie intake. Take this number, for example: for me, mine is 2950. If I want to lose weight, I would subtract 250-500 away from this; making it around 2700. Now, you should have your own individual calorie intake. So, with this you can work out your proteins, carbs and fats.
Your proteins will need to be around 1 gram of protein per lbs of body weight. So take your body weight in lbs and work out this number. For me it is 165g of protein. Multiply this number by 4 and that is how many calories the protein will supply you with. Take this number away from your total calorie allowance (e.g. For me = 2700-660 = 2040.
2040 is the amount of calories you will have dedicated towards fats and carbs. And obviously you want to reduce your fats, so take your original number of total calories (e.g. 2700) and multiply this by 0.15 to 0.25 depending on how much of a percentage you want your diet to have fats. Once you have worked this number out, divide it by 9. So for me it would be 0.20 x 2700 = 540. So 540 of your calories will be fats, which is 60g of fat. (540/9 = 60)
So, so far you will know your numbers, for me these are 165g of Protein and 60g of fats. Equating to 660 + 540 calories, = 1200.
Now, take this away from your original daily calories, 2700-1200 = 1500. That's how many calories you will have dedicated towards carbs. Divide this by 4 and you will be consuming 375g carbs per day.
So for me it is: 165g,60g and 375g.
For you it will be whatever you work it out to be.
