Reduce excessive saturated fats whenever possible and eliminate hydrogenated fats. Replace those other fats with polyunsaturated fats such as flax or chia and monounsaturated fats such as olive oil and avocados. Poly and monounsaturated fats are considered "good fats" and should be a part of your diet.
Research shows that omega-3 fats from many sources of fish like cod, salmon, sardines, tuna and algae oil sources help improve health and fat loss. MCT oil is also another beneficial fat that has shown to help in the weight loss process and enabling faster ketosis and appetite suppression. Essential fatty acids (EFA) are required for optimum health and fatty acid metabolism. Avoiding "good fats" is a sure way to sabotage a fat-loss diet and degrade your health.
