And honestly, I know this may sound like odd advice, but I would eat more calories. Do a search for “adaptation” with posts by CT. Here is a long post where he says:
"The redical diet is good for a quick fix, but if performed over the long run it WILL lead to severe muscle loss regardless of how well planned your training is. 50g of BCAAs will help prevent some muscle loss.
But at over 300lbs there is NO WAY that you will prevent losing a good amount of muscle consuming only 1000kcals per day. Heck, you could be on many anabolics and still lose muscle with that deficit!
Now, your goal is to lose 80lbs, great! But how much time do you think it will take? Even if you were to lose 8lbs per week for the whole durating of the program, which is not realistic as your body will eventually adjust to the lowered caloric intake, it would still require 10 weeks to drop the 80lbs.
Are you planning on staying on the Radical diet for 10 weeks? If so I will venture as far as to say that you are likely to lose at least 15lbs of muscle, probably more. That is, if you do not go insane before that… I’ve known 125lbs figure girls who were starving on 1000 calories per day.
And as I mentionned, the body will eventually adapt to the caloric/nutrients intake you are giving it. At this point your progress will stagnate. What can you do when that happens? Drop down to 500 calories per day?!? Common!
And what do you think will happen when you increase food intake to normal levels? You will balloon back up! There is what is called a ‘‘relative caloric surplus’’; this refers to a level of food intake that is higher than what your body is used to receiving. When that happens, even if you are TECHNICALLY eating under maintenance, you will still gain fat.
For example if you get your body used to ingesting 1000 calories per day, after several weeks it will accept this as its normal feed amount, and then you suddenly increase caloric intake up to 2500 calories per day. That represents a relative surplus of 1500 calories per day, or over 10 000 calories per week (1 pound of fat = 3500 calories).
This relative surplus WILL lead to fat gain as long as your body has not adjusted back to the new caloric intake, and this will take weeks. So even though at 2500kcals per day you are maybe 1000kcals under your THEORETICAL maintenance level you will still gain fat until your metabolism adjusts.
Furthermore I don’t like to use plans relying on calories. The body doesn’t recognize calories, it’s only a measuring unit. It only recognize nutrients (quantity and quality).
I don’t know the training plan you are talking about, but a mistake peoples make when trying to lose weight is that they increase their reps and lift lighter weights. It is my belief that the best way to force your body to retain its muscle is to do everything in your power to maintain, or even increase, strength.
If you ask me you will not be able to sustain this plan until you reach your goal of losing 80lbs. And if you do, you will have lost almost as much muscle as fat. So in essence you will simply become a smaller version of what you are looking like right now.
I understand that fat loss and body transformation is an emotional issue. We want our body to change RIGHT NOW. But the fact of the matter is that you dug yourself into a pretty big hole; you can either try to do it fast or to do it right, which will require a long term approach."
Now this guy was eating less than you, but I think this still applies…And be sure you’re getting protein at every single meal - that means breakfast! In fact, your whole diet needs revamping. Look up articles by John Berardi, buy the book Precision Nutrition, and practice his “Effective Habits.”
