1 - after-lunch fatigue is often caused by an interruption in one’s ultradian rhythm, often induced by early consumption of caffeine. Wait a full ultradian cycle (90 minutes) after waking before caffeine consumption in the morning. Even for longtime early morning coffee drinkers, it’s actually pretty easy to break the habit and delay caffeine intake. (Early morning concentration does not suffer.)

2 - get early morning sunlight to ensure well-functioning internal clock and dopamine/cortisol/serotonin function.

3 - take a real rest after midday meals. Go for a walk. Do nothing. Hangout with friends. Read. Rests must be real (no social media) to be effective.

4 - if you like what you’re working on make the midday meal light and keep after it.

On a final note, oftentimes it is appropriate to shift into less-focused work later in the day. Humans experience less dopamine and less cortisol starting around midday, and serotonin or unfocused joy becomes a dominant force. (For me this happens something like 7 hours after waking. I do more abstract design work, write, connect with people, read, broaden strategic perspective, do whatever work I find most fun, or stop working altogether.)

Honestly, going for a walk or reading is more energy-demanding that social media. People default to social media because it provides the most pleasure for the least amount of energy expended.

It’s not about energy-demand – it’s about motivation circuitry (dominantly dopamine). Humans have a lot of “energy” to do a lot of different things irrespective of midday meals. The issue is motivation, flow states, feelings of reward, joy, cognition.

On this note, social media is a terrible rest as it makes the brain pump with endorphins, making it immediately more difficult to find motivation for anything with delayed dopaminergic effect.

Burning physical calories boosts mental energy, did you not know?
Andrew Huberman, is this you?

Valuable advice.
