Support your weight loss and exercise program by getting between 1.2 and 1.6 grams of protein per kilogram (or 0.55 and 0.73 grams per pound) of your body weight, recommends research published in the American Journal of Clinical Nutrition in 2013. For a 200-pound woman, this would suggest you aim for 110 to 146 grams of protein daily, split up among three to five meals.
Even tiny changes in how and when you eat can add extra pounds or shut down the weight loss process. Did you start skipping breakfast or other meals? Did you try to lose weight by cutting out all sugar but now you’re bingeing on sweets ? Are you eating too many dairy foods to get extra calcium for bone health? If you’ve eliminated meals or changed your diet for what you thought were health reasons, your weight can go up.

When you want something sweet, all those fat-free, sugar-free options seem like a smart choice for weight loss. But researchers at Cornell University found that overweight people who choose low-fat versions of snack foods rather than the regular kinds consume, on average, twice as many calories. "The terms 'fat-free' or 'sugar-free' can create a green light effect, triggering people to eat more," says dietitian Cynthia Sass, RD. But many fat-free foods have about the same number of calories (or more) as their full-fat counterparts. 
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.

It’s called a “beer belly” for a reason. Boozy bubbles are a major cause of belly bloat, as anyone who’s ever looked in the mirror after a few too many drinks can attest. But it’s not just the carbonation that is the culprit. Alcohol can lead to an overgrowth of bad bacteria in your stomach, leading to gas, not to mention all the empty calories that are going straight to your waistline. Instead, skip the alcohol altogether or limit yourself to one serving per day.
Choose Liquid Calories Wisely. Sweetened drinks pile on the calories, but don't reduce hunger like solid foods do. Satisfy your thirst with water, sparkling water with citrus, skim or low-fat milk, or small portions of 100% fruit juice. Try a glass of nutritious and low-calorie vegetable juice to hold you over if you get hungry between meals. Be careful of alcohol calories, which add up quickly. If you tend to drink a glass or two of wine or a cocktail on most days, limiting alcohol to the weekends can be a huge calorie saver.
