Undereating also decreases your body’s production of thyroid and energy hormones, leading to metabolic dysfunction over time. If you think you’re not eating enough calories and you’re worrying too much about calorie counting or food weighing, it could be time to take a step back and nourish and energize your cells with more calories, minerals, and vitamins .
Research reveals people frequently lose weight and burn fat on keto even without intentionally restricting or counting calories  .
Don’t Over Exercise or Underexercise
Overexercising can lead to exhaustion, especially if you’re not replenishing those calories you’re burning. On the other hand, not exercising enough can slow your metabolism and make you feel more fatigued. Studies show a sedentary lifestyle and sitting around can make you more tired! 
Movement is medicine, and it’s crucial you find the right balance! You might decide to talk to your doctor or personal trainer about finding a suitable exercise plan for you.
Eat More High-Quality Natural Foods
Processed keto foods shouldn’t be the focus or staple of your keto diet. Your body needs a diverse range of nutrients, so it’s important to stay away from dirty keto versions of your favorite comfort foods and snacks.
Prioritize fresh produce and healthy meats and fats. Doctors advocate eating the rainbow and the whole spectrum of colorful antioxidant-rich plant foods. Remember, it could take a few weeks or longer for your metabolism to adapt to eating healthier and more natural low-carb foods.
Eat More Fat
Most of your energy on keto comes from fat, so make sure you’re eating enough of it and eating the right kinds of healthy fats. Leave the fatphobia in the past and get ready to enjoy healthy fats like coconut oil and coconut milk, olive oil, grass-fed butter or ghee, grass-fed beef, wild-caught fish, avocado, nuts, nut butters, and seeds!
Without enough healthy fat for fuel, you risk feeling lackluster and fatigued. Don’t buy into the fales statement that fat makes you fat. Eating healthy fats can actually help with weight loss and metabolism.
