I have the opposite "problem" tho I don't mind. I wan't to gain weight but I just can't, whatever I do my weight just stays the same(fast metabolism). My advice for you would be to stop eating 3 meals a day but instead in the mornings just make a smoothie, and eat a big meal for lunch and don't eat for the rest of the day. Main reason why there are so many overweight people(not knowing if you are, but principle is the same) is that people eat 3 or more times a day, which doesn't let organs to settle down and relax. Because of that body processes food extremely quick because it is used to get another meal soon so it has to work fast which means it will leave alot of things unprocessed which mainly is just fats that start collecting together in the hips or belly.
Nope, that's wrong.
Every nutritionist will tell you that the healthiest way to get your weight in check is to eat
at least 5times a day.
Of course 3 main meals and 2 healthy snacks (vegetables and fruit not some sweets filled with sugar and salt).
Main meals shouldn't be filled with salt or fried. Don't mix carbs and protein. There is a lot of information about this on the net.
The next part is the water intake. Nobody is taking enough water and that's our main problem. The cells can't function properly without water.
The most important part is exercise. Some say that food is only 30-40% and exercise is 60% of success.
As for you, I guess you're still young and your metabolism is fast so it can tackle anything you throw at it.
After 25-30yr mark it starts to slow down and you get all of this weight problems.
But it'll never happen if you stay hydrated, eat healthy foods(nothing to do with quantity but the quality) and exercise as much as you can.
