TweetOK, I'm gonna have to question this. Yes, after a lay off your body may need a jolt to get things moving again, but what do you think training is? I believe thats a really "Big" Jolt to the ole body after a long lay off. As well as starting to eat properly to fuel your training efforts. That in itself is going to shock your system, especially if your food intake hasn't been timed properly and you haven't been in taking the proper amount of macros , etc. The biggest shocker to a body is "Feeding Frequency and Timing"~!
Okay, so lets just take a look at the diet you have above.
1st meal-
Well, yes oatmeal is a good BBing diet food, its easy to prepare, portable, Low in the glycemic index, which means that it yields sustained energy as it is released slowly, and it also does not spike insulin levels, thus making it an excellent carbohydrate for dieting and fat loss, high in fiber, and a healthy source of fats, such as GLA.
Breakfast is the most important meal of the day, it sets the tone for the rest of the days food consumption. Your body has been fasting all night, and your glycogen is low and your body is in a CATABOLIC STATE. (which means it's burning the muscle you are trying so hard to gain for fuel) Your body has been working hard to repair and rebuild from the stresses it may have encountered the day before.
Protein is absolutely necessary to build muscle mass, it's your muscles building blocks as there is no other nutrient which can rebuild muscle fiber. As you continue your workouts, you reach a situation where your muscles are torn and broken as a result. Only protein can repair this damage and allow the muscles to benefit from your exertions. Inadequate protein is a major stifler of progress and development. This is especially important to those who train natural.
A good protein choice for breakfast is a quick absorption protein such as whey protein.
The other meals, Hmm not bad, BUT, not enough calories either. You should be taking in minimum 10x your body weight, so 2300 cals is where you should build from. It's not a wise move to drop down under 1000-1200 cals aday anyway.
So you'll loose weight, but most of it is going to be precious Muscle! Muscle Wasting! Which I would want to think is what you want to keep and/or add. Its also going to slow and/or shut your metabolism down to a crawl.
There are better ways to shock and trick your body, starvation is not one of them. Thats when we have to go back to BBing basics 101~ Avoiding Plateaus, & seeing gains, by implementing "Periodization, specificity, overload and adaptation, principles back into our training."
Stay Strong~~!!!
