My food advice is to cut any and all highly processed food and eat natural foods. Bump up your protein via chicken and fish and eat fruits and veggies. Simple and very effective. WHen it comes to calories it's quality (protein, good fats vs complex carbs) over mere quantity.
Stay the course, stay on point, stay motivated, dedicated, and you won't be stopped. Discipline. Perseverance. Focus. Dig deep and you will be victorious.
