Many people exercise but see very little change to their bodies. Why? No amount of exercise will help you achieve your body goals unless your diet is controlled too.
If you struggle with over-eating, wearing a waist trainer can diminish your appetite. Instead of eating 2-3 large meals per day, you should feel fuller and may be more inclined to eat more smaller portioned meals throughout the day (eating more frequently can speed up your metabolism).
Persistently wearing your waist trainer and controlling food intake can result in a flatter, more toned and tighter looking stomach region, even when your waist trainer is off.
Waist trainers are not only great for appetite suppression, but also encourage an improved posture as it forces you to sit/stand in an upright position.
This can result in the relief of back pain and tension that you probably did not realize was caused from poor posture, in particular those who stand or sit for long periods at a time throughout the day e.g. retail, hospitality, office job.
In order to maintain your progress for long term, permanent results; your waist trainer should be used in conjunction with a healthy, balanced diet and moderate exercise.
