Sleep
Take care of your sleep hours because a bad rest can make you fat.
Don’t break with the good habits acquired
Keep making 5 meals a day and don’t forget to stay hydrated. They seem like two very basic points but it’s very easy to get back on the running.
Keep exercising
Just as you have to keep taking care of your diet, not only to not get fat, but for your health and well-being, your routine can’t disappear from physical activity. Talk to a trainer to adapt your routines, you may want to change cardio exercises for strength training.
