No flaming here but...
diet, exercise routine are horrible. You do seem to have excellent desire as shown by the number of days you work out, and desire and stick-to-it ness is 99% of the battle.
You're like I was about 5 months ago, only I was at 5'10" 194 and had many years of weightlifting under my belt- (not to mention a few too many 'cheezburgers'!) Plus the age was catching up. Now at 176, larger up top, smaller in the waist (2" less) and I'm toying with the idea of stepping up to the next level.
[I'm assuming that it is not your goal to "bulk up," rather that you are trying to loose weight (FAT, not muscle) and get a little more muscle.]
Diet:
1) Check out "Enter the Zone" by Barry Sears, PhD. It'll give you a logical approach to 'dieting' and how and why we lose weight, gain muscle, lose fat. It also strongly addresses insulin issues.
2) Calculate your diet based on lean muscle mass and protein requirements and balance the rest around that. You should not be eating more than 125-140gm of protein daily at your weight and activity level. You definitely should not be taking in more than 2000 calories.
3) Divide the protein into 3 meals, 2 snacks (snacks are 1/3 - 1/4 of a meal and are 2-3 hours after lunch and at bedtime, 2-3 hours after dinner).
4) Add 9 grams of carbs (see threads on 'good' carbs) and 1.5-2 gm of fat for each 7 grams of protein you consume.
This is the Zone, as simply put as can be possible. With this, you will loose weight, more importantly SIZE, while preserving muscle whether you work out seriously or not. Just walking for 45-60 minutes 3x weekly will do it. Be patient; the first few days are difficult but then you'll find you're never really hungry and have ridiculous energy to spare! Plus you can do little 'cheat' weekends if you like after a month or so.
Exercise:
1) You CANNOT work the same body part every day. If you can, then you're not working it hard enough. Muscles must be worked to exhaustion, then rested for them to damage, then repair themselves and subsequently hypertrophy (grow). Focus on muscle groups. There are many, many schools of thoughts on this and I am no expert.
Basically though, for example, work your biceps with 3 or more exercises on the same day. Keep going up in weight until your last sets are 4-6 reps, doing 3-5 sets of each exercise. Go from dumbell curl to straight bar to preacher or pulleys. Use accessory muscles (e.g. close grip pullups with hands facing you). Same with triceps, chest, shoulders and back, legs (if you want, I hate legs), etc... you MUST give them 48-72 hours to rest. And yes, they will hurt like hell for the first 1-2 weeks because you have been doing didly poo-poo up until now. Get a partner, trainer to push you and spot you and don't be afraid to try heavier weight, you don't know what you can't do until you drop it!
When you start to get to a respectable weight (175 or so) you'll decide whether you want to really bulk up or cut down and change your diet and exercise routine accordingly (more protein, etc...)
You can use the shakes but make sure you include them in your daily protein/carb/calorie count. You shouldn't need them at the point you are now.
Good luck, dude
