Also, it's hard to have too much protein. 

"It has been observed that the human liver cannot safely metabolise much more than 285-365 g of protein per day (for an 80 kg person), and human kidneys are similarly limited in their capability to remove urea (a byproduct of protein catabolism) from the bloodstream. Exceeding that amount results in excess levels of amino acids, ammonia (hyperammonemia), and/or urea in the bloodstream, with potentially fatal consequences,[1] especially if the person switches to a high-protein diet without giving time for the levels of his or her hepatic enzymes to upregulate. Since protein only contains 4 kcal/gram, and a typical adult human requires in excess of 1900 kcal to maintain the energy balance, it is possible to exceed the safe intake of protein if one is subjected to a high-protein diet with little or no fat or carbohydrates. However, given the lack of scientific data on the effects of high-protein diets, and the observed ability of the liver to compensate over a few days for a shift in protein intake, the US Food and Nutrition Board does not set a Tolerable Upper Limit nor upper Acceptable Macronutrient Distribution Range for protein.[2] Furthermore, medical sources such as UpToDate[3] do not include listings on this topic."

As long as you eat enough protein (ideally 1g per pound of lean body mass but 1g per kg of body weight is acceptable) being over on fat is fine. Fats and protein should be viewed as minimum values so it's fine to go over. Carbs are unnecessary so you don't have to worry about eating enough. Some people do low carb, some people find their exercise suffers if they keep carbs too low, do what works for you.

What's important about fats is the ratio of saturated vs. monounsaturated vs. polyunsaturated fats. Saturated fat has been demonized in the past but some is necessary. Half of your cells membranes are made up of by saturated fats. Saturated fats are easy to get in your diet so try to focus on incorporating more essential fatty acids into your diet. Oily fish and flax seeds are a great source of omega 3 EFA's. You can take a fish oil or flax oil supplement if you have trouble getting it from your diet. Omega 6's are very easy to get into your diet so there's not need to supplement it. Most people eat too many omega 6's and too little omega 3's so to maintain a good ratio you shouldn't supplement your omega 6 intake.

Sugar is just a carb. As long as you're eating enough fats and protein, your carbs/sugar aren't particularly important unless you have a medical issue that requires carbs/sugar to be monitored.

However, it should be noted that fructose and sucrose can only be stored as liver glycogen and not muscle glycogen. The liver can hold 100-120g glycogen so anything more than that will be converted to triglycerides. As long as you still have a calorie deficit this will even out. Just try to make most of your carbs glucose and not sucrose or fructose. Fructose in particular has been shown to decrease exercise performance, increased likelihood of gastrointestinal distress, and increase perception of exertion.

As long as you're under your calorie goal, you'll lose weight. Some people find that sugar (even from fruit) causes them to have more sugar/carb cravings so keep that in mind.
