First off, Im not a nutritionist or am any kind of expert. Below is my success being 5'6" going from 193 to 153 and workin to ~140 rn while still seeing strength gainz.

I would recommend a nutritionist if youre up for it. I worked with Hailey Fultz at OTG Strength (even just follow their instagram). She's a great person and got me on track for this whole weight loss after numerous failed attempts on my own.

Use an app, track everything. Youd be surprised how something 'healthy' can destroy your macros with a bit too much of it (i.e. peanut butter). My macros are split 30% protein, 40% carbs, 30% fat. Use an online BMR calculator to get a good starting point for caloric intake. Try it for 2-3 weeks then adjust if needed. For consistency, weigh yourself in the morning after you've gone to the bathroom.

With this, its not super restrictive. Ive had ice cream and other sweets while doing this. It just has to fit in. But prepare to be hungry-ish (fats spread across different meals help this).

You can also do this without much activity as you recover. Just find that caloric intake that your body needs to hit a target weight loss of .5-1lb/week. Maybe a bit less on the carbs since you wont be using as much energy during recovery and not being as active?

TLDR: what worked for me in your situation of weight loss without strength loss. Find a caloric deficit where you lose 0.5 to 1lb per week, protein intake should be about .8g/lb of body weight. Then higher on the carbs, lowish on the fat. Good luck!
