Don't eat sugar all day because you need the "kick" to get everything done. This is not only pointless, as sugar wreaks havoc on blood sugar levels and so causes energy crashes and mood swings, it is simply a very unhealthy thing to do.
Don't work more than you relax. Remember that, “All work and no play makes Jack a dull boy.” Balance your work life with some downtime and some fun time. If you are a bit of a workaholic there is probably something else that you are avoiding facing.
As with sugar, don’t drink 10 sugary drinks or ten cups of coffee to keep you going. Your adrenals will burn out and you will end up fatigued, after your blood sugars crash from too much sugar in your system. Sugar has been found to be as addictive as cocaine! Avoid sugar and caffeine and instead go for herbal teas or plenty of pure, fresh water.
Don’t be a couch potato binging on hours of Netflix. You will become lethargic and your muscles will become slack as they atrophy. You will develop a bad habit that will be hard to break.
Don’t snack on chips, cookies, and buttery popcorn. Go for healthy snacks like raw veggies and lo-fat dip. Preferably, avoid snacking at all and stick to three balanced, healthy meals per day.
