Better plan:

Eat whatever you like. Of course with mesure

Day 1: warm up, 3 sets maxing out on pull ups with 5 mins of rest between the sets

Day 2: the same but with dips insted of pull ups

Day 3: rest

Repeat

My body got soo much better by doing this in less than 6 months.

After you get to at least 5 of each you can try adding some light weights.
