Please help this diet/supp schedule?

Basically if you read my other post you guys know my situation. I'm 23 6' 200 with a gut, haven't worked out in 3 years. I now plan on lifting, running, and boxing.

The supps I plan on taking are 1 AD for 6 weeks with Tribestan for 3 weeks after, multivitamin,glucosamine,protein shake,BCAAs,glutamine, effervescent sugarless creatine, Potassium and Vit. C caps.

I also plan on drinking 5 liters of water a day.

The diet I want to start consist of

Breakfast 5:30 am
A bowl of keto rice krispies (21 g protein 4 g carbs) with skim milk
1 cup of green tea

Brunch 8:30 am
Tuna with fat free mayo

Lunch 11:30 am
1 chicken breast with BBQ sauce
1 vegetable serving either peas,green beans,corn,brocolli,asparagus

Dinner 3:30 pm
Rotisserie turkey with gravy, steamed veggies and green beans from boston market OR a Tuna and provolone cheese honey wheat wrap.
I will also be having 1 side salad with croutons and fat free dressing

Evening meal 6:30 pm
1 porterhouse steak with steak sauce
1 vegetable serving either peas,green beans,corn,brocolli,asparagus

Post workout/bedtime meal 10 pm
4 egg whites (no yolks)
Protein shake with skim milk

It's roughly 300 g protein and 85 g of carbs

What do you guys think?
