@_marc97 Yes, recomposition works. But it is an outcome rather than a complete action plan with a set of rules. The idea behind recomposition is to change drastically in body composition compared to any changes in scale weight. And recomposition does not have to be strictly equicaloric. Say, a person is on the lower end of the healthy BMI spectrum and over a year of strength training implementing progressive overload and eating approximately at maintenance (more like a tad bit above, person is not super strict at tracking, which is a very common scenario) and ends up with a scale weight 5-8 lbs heavier than they started out with, but lost 5-8 lbs of fat mass and gained 10-16 lbs of muscle mass (numbers are purely hypothetical and just to illustrate the point) in the process, I'd consider that a pretty successful recomp. Inversely, if a person starts out at the higher end of a healthy BMI and loses 5-8 lbs in total (because over their first year of progressive resistance training they ate either at maintainance or in a deliberate, small deficit), while they lost 10-16 lbs of fat and gained 5-8 lbs of muscle (this is probably a bit more realistic, numbers wise), they've recompositioned.
Beginners are usually in a good place for (equicaloric) recomp so long as they have relatively too little muscle mass and relatively too much body fat. That is because fat is an energy storage and you create demand for muscle by training with close proximity to failure in the gym. Fat and muscle are two distinct biologial tissues, the energy freed from fat oxidation can be used for muscle protein synthesis. As we progress and lose fat and build muscle, the rate of this process slows. (Think of any (bio)chemical reaction. In the beginning, when you have a lot of substrate and no product, product will form rapidly and the reaction slows until equillibrium. Then, to get the process going again, you either have to add more substrate or remove some product.) This is why a recomp at maintenance for the same net amount of progress is a 1-year project for a beginner, but a 10-year project for an advanced trainee if they refuse to change in weight for a while by increasing calories. They have so much less absolute fat to be used for that process.
That being said, your nutrition is likely holding you back. If not the only 1500 (are you extremely sedentary outside of your 2-3x/week?), then it's going to be the only 75g of protein, I would increase that to 1g/lbs of bw, to be on the safe side. Also, how are your workouts? Structured? Implimenting progressive overload in a linear fashion?
