To lose fat you may feel a bit hungry for some part of the day (in this case, morning), and energised the rest of the day. If you never feel hungry and you still lose weight, then great for you, keep that up.
The best advice I can give you is to “not get greedy”. If you’re losing size without starving yourself, you’re in an ideal position. Don’t try to mess with your diet so you can lose 1.5 pounds a week instead of 0.8 pounds. It’s much better to lose the size slowly while eating a nutritious diet, having good workouts, being energised and feeling good about yourself, rather than starving yourself, being weak and depressed just so you can lose the weight a bit faster. 90% of the people who take the second route (starving to lose weight fast), regain all their lost weight within 2 years! Does that mean you should eat more just because you lost 10 pounds in 3 weeks? That depends on how YOU feel. If you were starving yourself, consider eating a bit more (adjust your diet up), and slow-cook the progress… If you weren’t starving and felt great, keep it up. Just listen to your body, starving yourself is never the answer to sustainable fat loss.
