When you need to start somewhere but don’t know where, think small rather than big. Large things have a way of becoming too overwhelming: small things can be done.
Before you try to cut out all carbs, try increasing your protein and fiber intake.
Before you try 5 HIIT workouts per week, try increasing your steps and taking two or three 20 minute walks per week.
Before you try fasting, try having set meal times.
Before you try ice baths, try consistently sleeping for 7-9 hours.
