1. Avoid alcohol. Each time you get buzzed, it takes 3 to 4 days of your energetic potential away from you. It's a literal toxin for your body and brain and shown to increase risk of various cancers.
2. I would start a habit of lifting weights at least 3x a week. You lose 3 to 8% of muscle every decade after 30. Keeping muscle will put you ahead of everyone who didn't at 40.
3. Find a diet that helps you keep a healthy body composition and high energy. Food is fuel for your body and brain.
If I woke up 30 pounds overweight and wanted to lose it all by the end of this year, this is EXACTLY what I'd do:
1. Eliminate alcohol. When you drink your body prioritizes burning it first. Trying to burn fat while drinking alcohol is playing the game on hard mode.
2. Multiply your bodyweight by 12. That will be your daily calorie intake.
3. Multiply your bodyweight by .8. That will be the daily grams of protein you need to eat to maintain/build muscle while burning fat.
4. To keep it easy focus on hitting your calories and protein.
5. Set the right meal schedule:
- Last meal 3 to 5 hours before bed
- First meal 1-2 hours upon waking
- Second meal between them
6. Eat a breakfast containing 40g of protein to regulate hunger and appetite at night while building muscle.
