How I lost 30 lb without losing my strength
I went from 147 lb down to 117, then built back up to 147. Same bodyweight at the start and the end, completely different body, and way stronger. The biggest thing I learned: losing fat is easy to mess up in a way that also loses you muscle and strength. Here's what kept mine.
1. Keep lifting heavy
When you diet, your body needs a reason to hold onto muscle. That reason is heavy training. A lot of people switch to light weights and "toning" when they cut. That's backwards. Keep your main lifts (squat, bench, deadlift or whatever your big lifts are) in your program and keep the weight on the bar as heavy as you safely can. You might do a little less volume, but don't drop the intensity.
2. Eat enough protein, every day
Protein is what protects muscle while you're in a deficit. A practical target most people can use is about 0.7 to 1 gram per pound of bodyweight per day (roughly 1.6 to 2.2 g per kg). I spread mine across 3 to 5 meals. If that number feels huge, start where you are and add one protein-heavy meal or shake a day.
3. Don't crash diet
A small deficit beats a brutal one. If you drop weight too fast, your training suffers, your sleep gets worse, and you lose more muscle. Aim for about 0.5 to 1% of your bodyweight per week. For a 160 lb person that's roughly 0.8 to 1.6 lb a week.
4. Track the right things
The scale bounces around because of water, salt and food in your gut. Weigh in most mornings and look at the weekly average instead of one day. Also track your lifts. If your weight is going down and your lifts are holding steady, you're losing fat, not muscle.
5. Sleep and steps
The boring stuff matters. Sleep 7 to 9 hours so you can recover, and walk every day. Steps burn calories without beating up your recovery the way extra cardio sessions can.
The rebuild
After the cut, I slowly raised my calories and kept lifting. Because I hadn't lost much strength, I built muscle back fast. That's the whole point: cut smart, keep your strength, and the rebuild is the fun part.
Not medical advice. This is general education from my own training and what the research generally shows. If you have a medical condition, an injury, or a history of disordered eating, talk to a doctor or registered dietitian first.
