The number of people suffering from eating disorders and body image issues has been soaring over the past few decades, and children as young as 7, both men and women are afflicted by it. These can become really serious and makes people vulnerable to scores of illnesses since their immune system becomes compromised, and their life expectancy shortens as well. So, this obsession with losing weight through any means possible, be it by doing extreme diets, starving oneself, taking laxatives and whatnot are not healthy ways to lose weight, and in case you or someone you know is doing any of these things, it is strongly advised that you seek help because this can be dangerous in the long-term.
Eating very small portions is actually not a sustainable way to lose weight because our body will realize that there is a food deficiency, and for that purpose is will make your body run slower so that it does not need as much food, and over time your body will become used to barely getting any food. So, instead of eliminating entire food groups, it is better to just eat smarter, because healthy weight loss is possible, and that should be the goal. If you lose weight via unhealthy means then you are not just putting your health at risk, but you are also more likely to gain the weight back as well.
It is important that you educate yourself regarding different food groups and to know what kind of ingredients are good or bad for you. Incorporating more natural foods in your diet and cutting out unnecessary processed food is a great way to start. Apart from this, having a healthy workout plan where you work with a trainer going side-by-side is also a great way to lose weight and still be healthy and strong.
