In an Australian study, it was discovered that men with high-fat diets were more likely to suffer from daytime fatigue and poor nighttime slumber than men with low-ft diets. Scientists doing this study speculated that fat intake affects hormones, metabolism and the central nervous system, all of which interact with the circadian clock that regulates shut-eye. In addition, the lead author noted that sleeping poorly makes people crave rich, fatty foods thus creating a vicious cycle. The Dietary Guidelines for Americans recommends that adults get no more than 20 to 35 percent of their total calories from fat.
For those who complain of daytime fatigue and difficulty sleeping, do not think it is simply because you are getting old. Cutting down on the fat intake in your diet may take care of these problems. And of course, trusting in God and resting in His care are what we need to renew our strength and sleep good at night.
The Scriptures declare: “[It is] vain for you to rise up early, to sit up late, to eat the bread of sorrows [for] so he gives his beloved sleep.” Psalms 127:2. In Isaiah 40:31, the prophet writes: “But they that wait upon the LORD shall renew [their] strength, they shall mount up with wings as eagles, they shall run, and not be weary [and] they shall walk and not faint.”
To renew our strength and not be weary or fatigued and to be able to sleep in peace and rest, we need to trust in the Lord, wait patiently on Him and stay away from a high fat diet.
