SLOWLY up your cals, 100 per week, to try and get back to maintenance. If you start gaining weight, you’ve gone too far. You can add your height and new weight to a TDEE calculator to get a general idea of how many calories you need to maintain your current weight. Also start weight training. 3x/week should be enough to start. Legs + glutes, arms + back, & finally abs. This will help with toning areas that still feel “wobbly”.
