What to take for energy?

Answer 1

If you are lacking energy then it likely stems from a problem that cannot be solved by taking a pill or supplement. All foods contain energy in differing amounts, those with the most fat are generally the highest, but if you are experiencing lethargy, it is likely to be due to a hormonal problem in your body, and not through lack of energy intake.
To ensure you have sufficient energy, make sure you get enough sleep, are not eating/drinking high GI foods causing sugar crashes, and are not under too much stress.
If you are constantly fatigued then it is advisable to consult your doctor.
