In the morning I always eat some form of protein and it helps to keep me feeling full.
Example:
breakfast:
I prepare 1/4 cup steelcut oatmeal
3 eggwhites with spinach and a teaspoon of feta cheese
a couple of hours later I have a cup of herbal tea with a piece of fruit
and some ff yogurt
lunch:
usually a huge salad with tuna and veggies. I dress it with a tablespoon of balsamic vinegar and a tablespoon of olive oil
snack:
fruit and a few almonds
before dinner snack:
sweet potato
dinner:
lot's of veggies
small piece of chicken or fish
snack:
fruit with yogurt
I honestly never feel hungry and I lose about 1-2 lbs a week.
Eat more often and have more protein. Let me know how it goes.
