During the first week of a reduced calorie and carbohydrate diet, you will flush a lot of excess water and lose weight rapidly. This is neither unhealthy, nor an indication of what your rate of weight loss will be like during weeks 2 and 3. With that said, men should expect to see an 8 to 12 pound loss during these 3 weeks, and women will likely lose 5 to 10 pounds. 
You're probably familiar with high-intensity interval training (HIIT). When it comes to cardio, HIIT is definitely the best way to strip off body fat, to the extent that there's literally no reason to hop on a treadmill and run at a steady pace for 30 or more minutes unless you're an endurance athlete. And if you're reading this magazine, chances are you don't desire the physique of a marathoner.
“The best way to stick with a diet, is for people to put the fewest restrictions on themselves as possible,” Langer says. “There shouldn't be anything in the world that they shouldn't ever eat again.” Similarly, Albers recommends ditching the “don’t” list entirely. “Instead of trying to stop an old negative habit, focus on building a positive new one,” she says. “New habits crowd out the old without the struggle of trying to stop a behavior.”
Nuts, the second food to watch, contain a fair amount of carbohydrate, and it’s very easy to unwittingly scarf down large quantities. Cashew nuts are among the worst carb-wise – you’ll find that they contain around 20% carbohydrate by weight. For someone following a strict keto diet with a 20 grams of carbs per day allowance, this means that consuming 100 grams (which happens in a flash!) will have filled their daily quota. Peanuts tend to be around 10-15% carbohydrate – not putting them in the clear either.
Certain carbohydrates have a tendency to be poorly absorbed in your intestines and then rapidly fermented, leading to gas and bloating. Common culprits include refined carbohydrates and simple sugars—like those found in processed foods with added sugars. Excess sodium can also cause bloating due to increased water retention. Opt for freshly prepared foods and reduce processed, packaged foods to cut back on belly bloaters. In the morning, swap your sugar-laden bowl of cereal for this Green Smoothie, made with fresh fruits and vegetables to get your day started the right way.
If muscling up is key to shedding timber, you might as well do so efficiently. Rehash your recovery period by introducing short rest intervals within your sets. Switching your 120-second rest between sets to a 60-second intra-set break brings greater strength gains and increased power output, according to a study published in the Journal of Strength and Conditioning Research.
You must have noticed that some of your friends eat a lot of sugar-based foods, fried foods, or cold drinks. Yet, they manage to have a flat stomach, the reason being they have a very high metabolic rate. If your metabolism is not good, you may have a bloated stomach. Thyroid conditions, diabetes, and other medical conditions can be the reasons for slow metabolism.
"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."
