Those are okay-ish lifts. If you're positive that you can't make any more progress on what you're doing, here are a few suggestions:
- Madcow 5x5. Pretty much a continuation but pushes the progression less aggressively.
- 531. Your weights get heavier on a monthly basis here.
- Westside for skinny bastards. The title says it all.
(of course, there are plenty of other good ones)
Food hacks: first, get two scales. One for your food and one for yourself. You need to know your own weight.
Get enough protein to grow. The general consensus is 1g/lb of bodyweight, but I've seen 0.8g/lb work as well. Once that's covered, get your calories from healthy fats and carbs. They are cheaper and easier to consume in larger quantities. Some high-calorie foods are
- white rice
- olive oil
