As your body needs nourishment to function correctly, starvation diets are bad. Moreover, significantly limiting calories can result in vitamin deficits and physical side effects like weariness, lightheadedness, and hair loss.
Some diets advise cutting out all carbohydrates or fats in order to lose weight quickly. While it's true that cutting back on your intake of carbohydrates and fats will help you lose weight, this is not a long-term solution.
Cutting off carbohydrates and fat is not a wise move because both are necessary for your body to function. Fresh produce, lean proteins, healthy fats, whole grains, and fresh fruits and vegetables would all help to balance these macronutrients.
Supplements should not be used as a meal replacement or to improve general health. Protein smoothies are a good example of a meal replacement, but they should only be taken seldom.
Exercise is crucial for weight loss, but you don't need to push yourself too hard to see results. Overworking your body can result in burnout and damage.
Finding a hobby you enjoy and incorporating it into your lifestyle are the keys. Make sure you're doing physical exercise that you enjoy and can sustain over time, whether it's yoga, swimming, or walking.
