So long as you're getting the macro- and micro-nutrients your body needs, there shouldn't be. Complete protein, sufficient minerals and whatnot for proper bone/blood/eye/etc repair and growth, and so forth. Man of the "fad" diets skimp on the nutrient content part, though they can certainly zap pounds.

Going "clean" is a pretty good way to begin, for most folks. Eliminate as much packaged (labeled) products as possible. Eliminate as much refined additives as you can (which includes products with good amounts of sugar, sugar alternatives, sugar "alcohols" and the like). Get plenty of water. Consider a balanced intake, in which each intake has some portions of fats, proteins, carbs. Have plenty of vegetables and moderate amounts of fruits. Of course, not everybody's body is tolerant of all things. Many have allergic (inflammatory) reactions to surprising numbers of foods. Many don't react well to, say, spices. But, generally, a balanced diet of modest amounts of fats, proteins, carbs with suitable vitamins minerals from a wide range of foods can be a vast improvement over the typical intake many rely on these days.

Good clean wide-ranging intake in modest amounts, plenty of exercise and sleep ... and you should find the changes come on pretty quickly (within a week or two).
