You Overcompensate For Exercise.
Often people comfort/reward themselves with food after exercise. And more than often they eat more that they burnt during exercise.
You’re Not Getting Enough Sleep
Too little sleep slows down the metabolism, effects exercise performance (because of the lack of energy) and increases the appetite. It can also increase stress levels and add to weight gain.
Drinking To Much Sugary Drinks
Stick to fresh juices and water. Even when drinking fresh juices, keep an eye on the quantity. If you used 5 apples, and 4 oranges for example, make sure that you can eat that same amount without using the juicer. So make a selection of fruits and veggies you can eat in one portion and juice it. Do not use more.
You’re Eating Large Portions
Eating too much of anything causes weight gain. Try keeping to fist size portions. If you find you are still hungry, wait 1-2 hours before eating another portion or having a snack.
You’re Eating Too Little
Your body has a natural instinct to protect itself so when you eat too little it automatically goes into starvation mode, causing your metabolism to slow down drastically and your body to hoard fats & calories.
