Thing is, quality matters too. If you just eat less, you will lose weight, no matter what you still continue to eat. But if you eat mostly nutritionally vacant foods (sugar, white flour, saturated unhealthy fats, foods filled with chemicals and preservatives), you won't come even close to feeling your best. These things drain your energy and affect your skin and hair poorly, can make you feel depressed and lead to mood swings, constipation, bloating and trouble sleeping. Wholesome foods like fruits, vegetables, whole grains, and healthy fats contribute to glowing clear skin, shiny healthy hair, a regular digestive system, sounder sleep and feeling alert and happy.
Eat to live (don't live to eat) and keep moving.
