To avoid feeling hungry after a workout, eat a snack with at least 12 grams of protein before exercising, says Dr. Cheskin. And if you’re still hungry afterward? First, check in with yourself and make sure it’s actual hunger and not dehydration, says Dr. Cheskin. Then, eat a protein-rich snack that also includes some carbs, like a protein bar with whole grains.
Consequently, researchers have widely discredited the hCG diet, which involves using hCG injections, pellets, sprays, or drops, and consuming  as few as 500 calories daily. The diet is problematic not only because there’s a lack of research on hCG supplements, but also because the calorie requirement is dangerously low, potentially leading to nutrient deficiencies, fatigue, hormone imbalances, blood clots, and other issues. Thus, most experts agree the hCG diet is not safe for anyone, the Mayo Clinic notes. (35)

Aim to do ab work 3 or 4 times a week on non-consecutive days with at least 24 hours of rest in between sessions, says Gagliardi. During those sessions, you can start with simpler moves like crunches, bicycle crunches, and planks. Even though you may only be directly targeting your abs 3 or 4 times a week, you should still be activating your core (aka, tightening your ab muscles) in every workout you do, says Gagliardi.
By encouraging food tracking, calorie counting, and the consumption of mostly fruits, veggies, and lean protein (sugar and unhealthy fats are discouraged), you can theoretically lose as many pounds as you want with WW, as long as you do not deviate from your established plan. And, because WW does not prohibit any foods, it is one of the most sustainable diet plans out there. Once you get the hang of the points system, you can even do it by yourself for the rest of your life. 
Spending more time in the kitchen can help you shed belly fat, as long as you’re cooking with the right foods, according to one 2017 study. After analyzing data from more than 11,000 men and women, UK researchers found that people who ate more than five homemade meals per week were 28 percent less likely to have a high body mass index, and 24 percent less likely to carry too much body fat than those whole only downed three meals at home.
Contrary to other low-carb approaches, the South Beach Diet makes a clear distinction between “good” and “bad” fats (avocado oil is good, butter is bad), and only prohibits the consumption of certain, but not all, carbs. This means that, while the South Beach Diet has certain similarities with the keto approach, is not strictly ketogenic, but rather keto-friendly.
The one thing that is sure to make you lose weight is this simple equation: CICO, short for “Calories In, Calories Out.” In short, it means: a) if you eat more calories than your body spends, you’ll gain weight; b) if you eat less calories than you spend, you’ll lose weight. In spite of all their differences, all diet plans that aim to help you lose weight must adhere to this seemingly simple equation. However, most experts agree that, by itself, CICO is an incomplete and flawed approach due mainly to its focus on quantity over quality, and the fact that it doesn't take nutrients into account.
All bodies are not created equal, and this is why there is no one “magical” diet solution for all. What’s more, even when two people with similar body compositions try the same diet plan, the difference in results can be overwhelming. “Bodies react differently depending on their genetic makeup and metabolism rates,” said Barcelona-based and Certified Nutritionist Carla de la Torre, and added, “this is why, for example, some people can get abs on a bread and cookies diet, while others cannot get the desired 'six pack' even after undergoing rigorous eating and exercise regimes.” 
Even though theoretically anyone can benefit from a healthy diet, it’s recommended that you consult with your doctor before beginning a new diet plan. Also, there are people for whom certain plans may not be ideal, including people with diabetes, pregnant women, people allergic to certain foods, people with hypertension, and people with a history of eating disorders.
"Your body begins to work differently. This study proves that small amounts of nourishment throughout the day are better than the same amount of food concentrated in three big sittings. If we feed the body at regular intervals we send a signal to the body that it doesn't have to store calories. Conversely, when we skip meals we send just the opposite signal for the body to store calories, creating a negative effect on the metabolism." — Dr. Wayne Scott Andersen, co-founder and Medical Director at Take Shape For Life
