if you are relying on mostly pre prepared meals to make you feel better and perform at a high level, they will not work long term for you despite you having very good intentions and them marketing themselves as healthy.
If it seems too god to be true such as offering too good to be true healthy cheesecakes, too good to be ready meals with low calories then it usually is.
I would try getting back to basics, porridge for breakfast, jacket potato and things like beans tuna with some greens with it too (spinach etc), and then evening meal be made from scratch, some wholegrain pasta again with a protein source like fish, chicken, turkey etc with more vegetables, keeping your plate as colourful as possible in terms of veg is always a great idea, drink more water and all of this will complement heavily to a great results, as you are working hard at the gym.
Buying in pre prepared foods usually means eating foods that are loaded with chemicals and too much salt, as salt is a natural preservative designed to keep the food edible for an extended period of time.
When you make for from scratch, you know exactly what is going into it.
When you eat from scratch, watch the difference in your workouts compared to the pre prepared foods, there will be a NIGHT AND DAY difference to your energy and performance level overall.
