9.Walnuts
It’s those omega-3s again. Walnuts have one in particular that your body uses for energy (alpha-linolenic acid). Though nuts are high in calories, studies show that people who eat them don’t gain weight or have other signs of bad health from them. That could be because the fiber slows how your body takes them in and the “healthy” fats satisfy hunger.
10.Coffee
It’s where many of us get our morning caffeine jolt. And it works. It boosts your energy and keeps you more alert. Just don’t overdo it. Caffeine can make you jittery and interfere with your sleep if you have too much, you’re not used to it, or you have it late in the day.
