Yesterday at 1,192 calories (more or less) I had:
Morning: 2 cups of black coffee
Breakfast: 2 scrambled eggs with tofu, spinach and tomato (high protein, kept me full for ages)
Lunch: Big salad with iceberg lettuce, tomato, cucumber, beetroot, alfalfa sprouts, 50g of chicken breast, topped with flaxseed and dressed with oil and balsamic, plus peach iced tea diluted with water (I like it about half and half)
Dinner: Chicken soup, and 10 frozen red grapes (sounds bonkers, but I love them!)
I don't usually start eating until 11-12 in the morning, so it all carries me through until bedtime easily.
You said I just feel I'm not losing on 1400, I'm down one week then not the next... It's important to remember that your bodyweight WILL fluctuate. Water retention, inflammation from exercise, hormones...
Consistency is so key, and not changing your habits because of just one week's results on the scale. As long as there's a downward trend over time, short-term ups and downs are just a body being a body.
